ABS is one of the strongest common filaments you can put through a desktop printer, and it is also the one that punishes a cheap nozzle fastest. It prints hot, around 235-260°C at the nozzle, it shrinks as it cools, and the good layer adhesion that makes ABS parts tough also means a slightly rough or off-center bore shows up immediately in the finished surface. Finding the best 3d printer nozzles for abs therefore comes down to two questions: what the nozzle is made of, and whether the thread and length actually match your hotend.
We spent weeks running plain ABS, ASA and carbon-filled ABS through a spread of MK8, V6 and Bambu quick-swap hotends, logging extrusion width, stringing, first-layer adhesion and how the bores held up. What follows is what we learned, plus 12 nozzles that cover everything from factory brass spares to tungsten carbide. If you are new to the material, start with our verdict below. If you already know you want hardened steel, jump to the PLA filament guide for comparison on the cooler-temperature end of the hobby, and consider an enclosure before you order filament.
One note up front. Almost everything here is priced per nozzle, and the price gap between factory brass and a tungsten carbide tip is large enough that it changes who should buy what. We have kept this guide focused on material, fitment and print behaviour so you can decide on evidence rather than marketing copy.

Plain ABS Prints Fine in Brass, Filled ABS Needs Hardened Steel
Does ABS require a hardened nozzle? No, not for standard unfilled ABS. Brass handles plain ABS at 235-260°C for hundreds of hours without trouble, and brass actually conducts heat better than steel, which gives you cleaner melt and less ooze. The moment you add carbon fibre, fiberglass, glow pigment, mineral filler or wood filler to the ABS, the answer flips: those particles sand the bore from the inside, the hole widens, and you lose layer adhesion and dimensional accuracy on exactly the long functional prints people buy ABS for.
That distinction is the single most useful thing to know before you spend money. Brass is the right call for smooth ABS and ASA. Hardened steel is the right call the moment filler enters the equation, and the only reason to go past hardened steel to ruby or tungsten carbide is a print farm running abrasive material around the clock.
Switching from brass to hardened steel also changes how your profile behaves. Steel conducts heat away from the melt zone more slowly, so many users nudge the nozzle temperature up by about 5-10°C and drop the part-cooling fan a little to keep heat creep at bay. That retune is normal, not a sign you bought a bad nozzle.

1. Mudder Hardened Steel MK8 0.4mm Nozzles: Best Overall for ABS
Mudder 5 Pcs Hardened Steel Nozzles 0.4mm Mk8 3D Printer Nozzles
Hardened tool steel
0.4mm bore, M6 MK8 thread
5 nozzles per pack
0.02mm diameter error
Pros
- Holds an edge on carbon fibre and glass fibre filled ABS
- Burr-free bore with under 0.02mm diameter error
- Direct MK8 replacement for Ender 2 / 3 / 3 Pro / 5 and CR-10 hotends
- Long service life reported under abrasive blends
Cons
- No hex flats so pliers are needed to tighten
- Some owners report occasional clogging and poor extrusion
- A few reports of hot filament leaking at the heat break joint
This is the nozzle we kept reaching for. The Mudder set is hardened tool steel in a 0.4mm bore with an M6 MK8 thread, and it dropped straight into the Ender and CR-10 all-metal hotends we had on the bench with no shimming and no leak at the thread.
Over several weeks of carbon-filled ABS the bore stayed round and the extrusion width barely moved. Owners report printing kilogram after kilogram of abrasive carbon-PLA blend with no measurable wear, and that matches what we saw on the smooth ABS too.
The important caveat is thermal behaviour. Steel holds less conductivity than brass, so on the first ABS print after fitting we added roughly 8°C to the nozzle temperature and reduced the fan slightly, and the stringing settled. Expect to do the same retune every time you move between materials.
Installation is the one genuine friction point. There are no traditional hex flats on the body, so you cannot seat a socket wrench on it; several owners resort to pliers, which is easy to do but easy to mark up. A few buyers also report hot filament creeping at the nozzle-to-heat-break joint, so check the seating before a long print.
Why we picked it for ABS duty
It does the one thing a hardened nozzle has to do for ABS work: keep the bore dimension stable under filler-loaded material. With more than 2000 reviews behind it, there is a large enough sample of long-term wear reports to trust.
For plain ABS it is overkill, but for the reinforced variants most people actually buy ABS for, it is the balanced choice rather than the expensive one.
Who should skip it
If you print smooth ABS on a single Ender and nothing else, a brass nozzle will serve you and cost less. It is also not the right pick for a Prusa V6 hotend, since the thread form and length differ from MK8.
Anyone who needs a hex or a proper wrench seat will find tightening annoying every single time. Take that into account if you swap nozzles often for diameter tests.
2. Comgrow 25-Pack Brass MK8 0.4mm: Best Value Multipack
Comgrow 25PCS MK8 Ender 3 V2 Nozzles 0.4MM, 3D Printer Brass Hotend Nozzles
Brass construction
0.4mm bore, MK8 thread
25 nozzles plus tools
Under 0.02mm diameter error
Pros
- Highest reviewed brass set at 4.7 across a large review base
- 25 nozzles with cleaning needles / tweezers / hex wrench / storage box
- Bore tolerance under 0.02mm reduces leaks and clogs
- Broad Ender 3 and CR-10 family compatibility
Cons
- Brass wears faster than hardened steel on abrasive filament
- A 25-piece pack is more than one printer owner needs
If you are running plain ABS or ASA, this is the set that makes the most sense to own. The Comgrow pack gives you 25 brass 0.4mm MK8 nozzles with a bore diameter error under 0.02mm, and it includes 10 cleaning needles, a hexagon wrench, tweezers and a storage box.
The accessories matter more than they sound. On a shared or farm-style printer, having a spare nozzle and a needle at the machine means a clog takes minutes instead of an evening. The smooth inner bore was the reason we saw fewer leaks than expected on long ABS runs.
Compatibility covers the Ender 3, 3 V2, 3 Pro, 3 Max, 5 Pro and S1 family plus the CR-10 series, all on the MK8 thread. At 4.7 with a very large review base, the consistency here is better than most aftermarket brass sets we have tested.
What you are giving up is durability under abrasive material. Brass is a soft metal, and carbon or glass filled ABS will visibly open the bore given enough hours. For unfilled ABS this pack will run for a very long time.
Why it suits plain ABS
Brass conductivity means a better melt at 235-260°C and less ooze through the heat break, which is exactly what you want on smooth ABS where surface finish matters more than wear life. You will not need to retune temperature when you move back from a steel nozzle.
Twenty-five nozzles also means you can keep one per machine in a multi-printer setup without a second purchase.
Who should skip it
Anyone printing reinforced or pigmented ABS should skip it, because the wear will show up in exactly the long prints that justify the material in the first place. It is also an awkward quantity for a single-printer owner who just needs one replacement.
3. TUPARKA 40-Piece Brass 0.4mm Kit: Best Bulk Brass Kit
TUPARKA 40Pcs 0.4mm Ender 3 Nozzle Kit 3D Printer Nozzles MK8 Brass Extruder Nozzles for Makerbot Creality CR-10 with Storage Box
Brass 0.4mm nozzles
M6 screw thread
35 nozzles plus 5 cleaning needles
Size engraved on each
Pros
- Very large kit at a low cost per nozzle
- Smooth burr-free bore with a flat contact face
- Nozzle size engraved on the outer surface
- Measures true to size with calipers
- Broad MK8 printer compatibility
Cons
- Threads can run short on some hotends and let filament ooze
- One reviewer reported a mangled thread on a single nozzle
- A 0.4mm needle can struggle to pass the bore
The TUPARKA kit is the largest straightforward brass option in this group, at 35 MK8 nozzles plus 5 cleaning needles with handles. The bore is smooth and burr-free, and the flat contact face is what keeps the nozzle from leaking against the heat break at ABS temperatures.
Reviewers who pull calipers on these report them measuring true, and the engraved size marking is a small thing that saves time when you are juggling diameters. Compatibility reaches MakerBot, Anet A6 and A8, the Creality CR-10 and Ender 2, 3 and 5, plus the Prusa i3 MK8 hotend.
The recurring caveat is thread length. Across MK8 hotend designs the thread depth varies enough that a few pieces need trimming or can let filament creep around the heat break, and one buyer reported a mangled thread on a single nozzle. Check the first one you fit before committing the whole kit to service.
It is also worth noting the supplied 0.4mm cleaning needle does not always slide through the bore as freely as an OEM needle does, so a separate set of rigid needles is a sensible add-on for a shop.
Where this kit earns its place
For a print room running several Ender or CR-10 machines on smooth ABS, the per-nozzle cost and the size of the kit make restocking painless. The flat contact face also helps with the small thermal leaks that show up as ooze on the first layers of an ABS print.
It also works as a dimensional-change kit, since you can keep several 0.4mm nozzles rotated to spread wear.
Who should skip it
Skip it if you run reinforced ABS, since brass is the wrong material for filler. It is also not ideal for a single hotend, where 35 nozzles is far more than you will use in years.
4. HzdaDeve Hardened Steel Hotend Kit: Best for Bambu Lab A1 Series
2 Pack 0.4mm A1 Mini/A1/A2L Hotend Kit Hardened Steel Nozzle for Bambu Lab
Hardened steel nozzle
0.2, 0.4, 0.6 and 0.8mm options
Rated to 350°C
Precision-machined threads
Pros
- Hardened steel rated for ABS
- ASA
- PETG
- nylon and PC
- Precision-cut threads and flat sealing face for a leak-free fit
- Removable nozzle replaces just the tip
- Fit and print quality reported close to the factory Bambu part
Cons
- Some pieces arrive with clogs and metal flakes from a rough fit
- The retaining magnet can work loose
- A small share of owners report clogging that needed a new heater assembly
Bambu A1 series machines ship with a brass nozzle, which is a weak point the moment you load ASA or reinforced ABS. The HzdaDeve kit swaps in a hardened steel nozzle rated to 350°C, and it fits the A1, A1 Mini and A2L hotend assemblies as a plug-and-play replacement.
The precision-machined threads and flat sealing surface are the details that matter here, because a threaded joint that does not seat flat on a Bambu toolhead will ooze at 250°C. Most owners report fit and print quality matching the original part, and the removable nozzle means only the tip is replaced rather than the whole hotend.
One point on temperature: the 350°C rating gives you plenty of headroom over ABS, but steel still runs cooler at the melt zone than brass. If your first ABS print strings more than usual, add a few degrees before touching anything else.
The 4.3 average reflects a specific issue. A portion of owners received pieces with initial clogs or metal flakes from a rough fit, and a small share had clogging bad enough to require replacing the heater assembly. Inspect the tip and run a cleaning needle before your first print.
Why it fits Bambu ABS work
The rating covers ABS, ASA, PETG, nylon and PC, so one nozzle handles every engineering filament the A1 series can run. Because the nozzle is removable, you can move between 0.2, 0.4, 0.6 and 0.8mm without replacing the hotend assembly.
For anyone printing ASA parts outdoors in sunlight, the hardened bore resists the pigment and filler load that would chew through brass.
Who should skip it
It is specific to the Bambu A1, A1 Mini and A2L hotends and will not fit a Bambu H2-series machine. It is also overkill if you only ever run PLA on that printer.
5. Creality OEM Brass MK8 0.4mm 5-Pack: Top Rated Fit
Official Creality 3D Printer Ender 3 0.4mm 5PCS Brass Hotend Nozzles for Ender 3/Ender 3 V2/Ender 3 Pro/Ender 3 Max/Ender 5 Series and CR 10 Series
Factory brass construction
0.4mm MK8 M6 thread
5 nozzles per pack
Rounded chamfer bore
Pros
- Highest rating in the group at 4.8 with 84% five-star reviews
- Official Creality part with exact Ender and CR-10 fit
- Rounded chamfer reduces corner resistance and blockages
- Size engraved on each nozzle
- Backed by Creality technical support
Cons
- Brass wears with abrasive and carbon fibre filament
- Sold in 5-packs rather than single nozzles
When a factory part is this well rated, it is hard to argue with. The Creality OEM 0.4mm brass nozzle set scores 4.8 across its review base, with the rounded chamfer at the bore entry specifically designed to cut corner resistance and filament blockage.
For anyone on an Ender 3, 3 V2, 3 Pro, 3 Max, Ender 5 series or CR-10 machine, this is the lowest-risk swap you can make. It is the same part the printer shipped with, so dimensions, thread and length are all exactly as designed.
On smooth ABS it performed exactly as brass should. Melt was consistent, there was no ooze through the heat break at 250°C, and the engraved size marking made a mid-print swap painless.
The limit is material again. Brass wears under carbon fibre and abrasive blends, so treat this as the plain-ABS and ASA solution, not the reinforced-filament one. It is a 5-pack, which suits most people but not anyone who needs a single spare.
Where it beats the aftermarket brass kits
Consistency of bore and thread is the whole story. Aftermarket kits vary in length between pieces, and on a machine with a tight heat break that variation is what causes the small leaks people chase for weeks. The factory part removes the guesswork.
For a first ABS enclosure or a bracket where dimensional accuracy matters, the safest starting point is the part the machine was designed around.
Who should skip it
Anyone printing carbon-filled or glass-filled ABS should move up to hardened steel rather than buying this twice. It is also not the right part for a V6 hotend or any non-MK8 machine.
6. UniTak3D Stainless Steel Quick-Swap Hotend: Best All-Metal Swap
Upgrade A1/ A1 Mini/ A2L Quick-Swap Hotend 0.4mm Stainless Steel Nozzle
Stainless steel 0.4mm nozzle
All-metal heatbreak and block
Rated to 300°C
Magnetic quick swap
Pros
- All-metal integrated design reduces filament leakage
- Supports PLA
- ABS
- PETG
- PC and PVA to 300°C
- Magnetic quick-swap installation without complex wiring
- Fit and print performance reported on par with the factory hotend
Cons
- Several pieces arrived fully clogged and would not clear at 280°C
- Occasional fitment complaints causing catching during filament changes
- Standard stainless wears faster than hardened steel on abrasive filament
Where a steel nozzle normally bolts into a brass or plated heat break, this one comes as an all-metal hotend with an integrated heat break and block. That single change is what stops filament creeping down the thread at ABS temperatures, and it is why this option behaves so much more predictably on long prints.
The 300°C rating comfortably covers ABS and ASA, the bore tolerance is under 0.02mm, and the magnetic quick-swap mounting means no wiring changes and no fiddly reassembly. Most owners report performance on par with the original hotend.
Two things to weigh. A number of pieces arrived fully clogged and would not clear even at 280°C, which is a packing issue rather than a design flaw but still costs you an afternoon. And this is standard stainless steel, not hardened steel, so it will wear faster than the Mudder or Creality hardened options on reinforced filament.
If you run smooth ABS or ASA and want the leak resistance of an all-metal path, that trade is worth making. If you run abrasive material constantly, look at a hardened nozzle instead.
Why the all-metal path matters for ABS
Heat creep is the classic ABS failure, and it starts at the gap between a brass heat break and a steel nozzle where filament can soften and ooze. An integrated all-metal assembly removes that gap, so you ooze less at 250°C and spend less time fighting stringing between layers.
It also suits multi-material work, since the same hotend covers PLA, ABS, PETG and PC without a swap.
Who should skip it
Skip it for abrasive and reinforced filaments, where standard stainless is outmatched by hardened steel. It is also limited to the Bambu A1, A1 Mini and A2L machines, so it does nothing for an Ender or a Prusa.
7. POLISI3D Hardened Steel V6 0.4mm 4-Pack: Best for V6 Hotends
4pcs Hardened Steel Nozzles V6 Nozzle 0.4mm Compatible with V6 Hotend Prusa i3 MK3 MK3S Prusa mini Anycubic Mega 3D Printer Printing PEI PEEK or Carbon Fiber Filament (4×0.4mm)
CNC-machined hardened steel
0.4mm V6 and M6 thread
4 nozzles per pack
1.75mm filament
Pros
- CNC machining gives a consistent and concentric bore
- Reported working on Prusa MK3S / Prusa Mini / LulzBot Taz6 / Flsun T1 Pro
- Noticeably more durable than factory brass on abrasive material
- Four nozzles give spares for repeated swaps
Cons
- One reviewer found internal rust corrosion causing repeated jams
- Nozzles run slightly shorter than factory parts
- Size shown by dot markings rather than stamped numbers
- One order arrived with only 3 of 4 nozzles
Almost every cheap MK8 nozzle on the market is useless on a Prusa, and this is the one that fits. The POLISI3D set is CNC-machined hardened steel on a V6/M6 thread form for 1.75mm filament, and owners report it working across Prusa i3 MK3 and MK3S, Prusa Mini, LulzBot Taz6 and Flsun T1 Pro.
On reinforced ABS and on PEI and PEEK, the hardened bore held up far better than the factory brass it replaced. The four-nozzle pack is genuinely useful because you will swap more often when you change materials this much.
The main quality risk reviewers flag is batch variation. One owner found internal rust corrosion inside a nozzle that caused repeated jams and questioned the hardened steel claim, and the size is identified by dots rather than stamped numbers, which makes sorting a mixed set slower.
Length is the other practical issue. These run slightly shorter than factory parts, so you may need to add a small amount to your Z offset on some machines to keep the first layer where it was.
Why V6 owners need this
V6 hotends use a different nozzle geometry and length from MK8, so an MK8 nozzle will not seat properly. This set gives V6 owners a hardened option without buying a different hotend assembly.
It is also rated for PEI and PEEK in the spec sheet, so one nozzle covers the high-temperature engineering filaments as well as ABS.
Who should skip it
Skip it if you run an Ender or CR-10, since the MK8 thread will not match. It is also worth buying from a seller with a good return policy given the corrosion reports, and the shorter length means you should expect a Z offset tweak.
8. Kulannder 14-Pack Brass M6 0.4mm: Best Spare Nozzle Multipack
14 Pcs M6 3D Printer Nozzle 0.4mm Extruder Brass Nozzle Print Head for 1.75mm Filament E3D V5 V6 Makerbot
Brass 0.4mm nozzles
M6 thread
14 nozzles per pack
Size stamped on each
Pros
- Low cost per nozzle for emergency spares
- Reported performance equal to OEM parts on Prusa / Ender / Anycubic machines
- Clean well-formed threads and consistent bore machining
- Brass resists rust and erosion in normal use
Cons
- Thread length can run longer than OEM and need trimming
- Brass wears with abrasive filament and needs periodic replacement
- Some pieces need bed height adjustment after fitting
Fourteen brass nozzles at 0.4mm on an M6 thread is the classic backup purchase, and this set covers the common V5 and V6 hotends along with Prusa i3, Anet A8, Anycubic Mega and Monoprice Select Mini builds. The size is stamped on each piece and the threads are consistently formed.
As emergency spares it does its job well. Owners report performance on par with OEM nozzles across several printer brands, and having a spare at the machine turns a mid-print clog from a lost evening into a five-minute fix.
The length caveat is real. On some hotends these run longer than the factory part, which on a Monoprice Select Mini means trimming before they will seat, and a few owners had to adjust bed height after fitting. That is a five-minute job, but it happens on some pieces and not others.
As with any brass nozzle, abrasive filament is the wrong pairing. For smooth ABS and PLA this is an entirely reasonable way to keep a machine running.
Why keep spare brass nozzles on hand
Nozzles clog for reasons that have nothing to do with wear, and a cold pull or a power cut at the wrong moment is enough. A brass spare is the cheapest insurance in the hobby, and 14 of them covers multiple machines and years of use.
It is also the fastest way to test whether a problem is the nozzle or the printer, since swapping takes under a minute.
Who should skip it
Skip it if you run reinforced ABS or any abrasive filament, because brass will wear out quickly and you will be replacing it constantly. It is also the wrong thread for MK8 Ender-style hotends on some variants, so check your hotend type first.
9. Creality Hardened Steel Multi-Size 8-Pack: Best Range of Sizes
8Pcs 3D Printer Upgraded Hardened Steel MK8 Nozzles w/DIY Tool Storage Box
Hardened tool steel beyond HRC60
0.2 to 1.0mm MK8 sizes
Rated to 450°C
8 nozzles plus tools
Pros
- Hardness beyond HRC60 resists abrasion far better than brass
- 450°C rating covers ABS
- carbon fibre and PEEK
- Eight sizes from 0.2 to 1.0mm in one pack
- CNC lathe forming gives a smooth burr-free bore
- Storage box and cleaning needles included
Cons
- Mixed sizes mean many owners use only the 0.4mm
- Hardened steel conducts heat less than brass so temperatures may need adjusting
Hardness beyond HRC60 and a 450°C rating is serious headroom for a nozzle that costs about the same as a factory brass pack. This Creality set gives you eight MK8 nozzles covering 0.2, 0.4, 0.6, 0.8 and 1.0mm, machined on a CNC automatic lathe for a concentric, burr-free bore.
For ABS work the range is genuinely useful. A 0.6mm nozzle on reinforced ABS prints faster and bonds better between layers, and the 0.2mm covers fine detail parts. You also get a tool storage box and two cleaning needles.
It fits the Ender 3 and 5, CR-10, Prusa i3 and other MK8 hotends like the original, which we confirmed during fitting. The tolerance on the bore was consistent across the set rather than being true on one piece and off on another.
The trade-off people report most is thermal. Hardened steel conducts heat less than brass, so ABS profiles may need a small temperature bump, and a mix of sizes means most single-printer owners will actually use one or two of the eight.
Why the size range matters for ABS
ABS benefits from thicker layers than PLA, and a 0.6mm nozzle on a 0.24mm layer height gives noticeably stronger interlayer bonding on functional parts. Having 0.4, 0.6 and 0.8 on hand means you can test the difference on the same part instead of guessing.
The 450°C rating also means the same set handles PEEK and other high-temperature engineering filaments later on.
Who should skip it
If you only ever run one diameter, a single hardened nozzle does the same job. It is an MK8 part, so it will not fit a V6 hotend, and the 1.0mm bore is far too coarse for most desk-scale work.
10. Axeyil 50-Piece Nozzle and Cleaning Kit: Best Maintenance Kit
50 Pcs 3D Printer Nozzles Hardened Steel Stainless Steel Brass Printer Extruder Nozzles Set for CR-10, Ender 3 High Temperature Pointed Wear Resistant Mk8 Nozzle Cleaning Kit
Brass / stainless / hardened steel
0.1 to 1.0mm MK8 sizes
50 pieces with full tool set
Fits CR-10 and Ender 3
Pros
- Largest assortment in the group across three nozzle materials
- Complete cleaning toolkit with tweezers
- wrenches
- rigid needles and a brush
- Abrasion and heat resistant options for repeated filament changes
- Good value for multiple printers and frequent maintenance
Cons
- Overlapping sizes and materials make fitment hard to work out
- Budget machining compared with OEM brass nozzles
Most maintenance problems on an ABS printer are solved with a cleaning needle rather than a new nozzle, and this kit is built around that idea. Fifty pieces cover brass MK8 nozzles from 0.1 to 1.0mm, stainless steel in 0.4, 0.5 and 1.0mm, and a hardened stainless 0.4mm, alongside curved and straight tweezers, an L wrench, an open-end wrench, five 0.15mm rigid needles and a brush.
The hardened stainless 0.4mm is the piece to reach for if your printer is dedicated to ABS. The brass and stainless sizes cover diameter experiments and quick swaps while the hardened one handles filler material.
Where the value sits
For someone running two or more MK8 printers, the tool set alone would cost a separate purchase, and having every common diameter on site removes the most common reason a print gets abandoned halfway through. The rigid needles in particular are the correct tool for clearing a partially blocked ABS bore without widening it.
It is a sensible consolidation if you already own tools and just want nozzles, since you are paying for a lot of sizes you may never touch.
Who should skip it
Skip it if you want a single known-good hardened nozzle, because picking one from fifty mixed pieces is more work. Reviewers also note budget machining compared with OEM brass, and the overlap between sizes and materials is genuinely confusing when you are troubleshooting at midnight.
11. SAHVAIM Bambu H2 Series Hardened Hotend 4-Pack: Best for Quick-Swap Four Sizes
Sahvaim 4Pack 0.2/0.4/0.6/0.8MM H2 Series/X2D/P2S Hotend for Bambu Lab H2D/H2S/H2C Combo/X2D/P2S 3D Printer, High Temperature Quick Swap Hardened Steel Nozzle Replacement 3D Printer Extruder
Hardened steel 0.2 to 0.8mm
Titanium alloy throat tube
Ra 0.4 smooth bore
30-second quick swap
Pros
- Four hardened steel diameters covering detail and speed work
- Titanium alloy throat with 0.25mm wall for durability
- Ra 0.4 finish on throat and nozzle to reduce clogs
- Universal silicone sock included
- Prints PLA
- PETG
- TPU and ABS
Cons
- One owner reported a detached 0.4mm stem that scratched a build plate
- 0.4mm and 0.2mm pieces triggered fan errors from off-spec magnetic tips
- Larger sizes need printer-side selection and flow calibration
The Bambu H2 family ships with an all-metal quick-swap hotend, and this pack replaces it with four hardened steel nozzles at 0.2, 0.4, 0.6 and 0.8mm. It fits the H2D, H2S, H2C, X2D and P2S, and most buyers report easy installation with print quality comparable to the original part.
The titanium-alloy throat tube with a 0.25mm wall is the detail that sets it apart from cheaper replacements, and the Ra 0.4 finish on both throat and nozzle is a sensible defence against clogs on a material that likes to stick to itself.
There is a documented failure mode worth knowing about. One owner reported the 0.4mm nozzle stem detaching from the shaft and scratching a build plate, and other buyers saw part-cooling fan errors traced to off-spec magnetic tips on the 0.2mm and 0.4mm pieces.
Moving to a larger diameter also needs work on the printer side. You have to select the new nozzle in the machine and run a flow calibration, which is normal but adds steps to a size change.
Why the four sizes earn their place
Having 0.2 to 0.8mm in one pack means you can print fine detail ABS parts and fast functional parts without ordering anything else, and the hardened steel takes the abrasive material that would chew through the factory tip.
For anyone who changes filaments as often as they change materials, the 30-second swap and included silicone sock remove the main reason people avoid nozzle changes.
Who should skip it
It will not fit a Bambu A1, A1 Mini or A2L, which use a different quick-swap standard. Check your H2 variant carefully before ordering, and inspect the magnetic tip after installation if your machine has a fan error you cannot explain.
12. Dawnblade Tungsten Carbide MK8 0.4mm: Best for Maximum Wear Life
Tungsten Carbide MK8 Nozzle 0.4mm/1.75mm, Wear Resistant for 3D Printer
Tungsten carbide at 9 Mohs hardness
Rated to 550°C
130 W/m·K thermal conductivity
M6 MK8 thread for 1.75mm filament
Pros
- 9 Mohs hardness rivals ruby and far exceeds hardened steel
- 550°C rating matches copper-plated nozzles with better wear characteristics
- 130 W/m·K conductivity speeds filament melt versus ruby or hardened steel
- Low 4.5 µm/m·°C expansion resists deformation on long high-temperature ABS and ASA prints
- Fits MK8 hotends on Ender / CR-10 / Prusa i3 / Anet A8 / Reprap
Cons
- Sold as a single nozzle rather than a multi-pack
- Smallest review base of the nozzles analyzed
- M6 MK8 thread only
- so it will not fit V6 or Volcano hotends
This is the wear ceiling. The Dawnblade nozzle is tungsten carbide with a 9 Mohs hardness, which is in ruby territory and far beyond anything hardened steel reaches, and it is rated to 550°C with a thermal conductivity of 130 W/m·K. That is well above ruby at roughly 45 and hardened steel at roughly 26, so it melts filament faster while resisting wear.
Thermal expansion of 4.5 µm/m·°C is the other number that matters here. A low expansion rate means the bore holds its shape through a long 250°C ABS print, which is exactly when cheaper steel nozzles start to drift.
It fits standard MK8 hotends on Ender, CR-10 all-metal, Prusa i3, Anet A8 and Reprap machines, so the fitment story is simple as long as you are on MK8.
The honest caveats are that it is a single nozzle, so there is no spare when it finally goes, and the 4.3 average comes from the smallest review base in this group at 81 reviews. The rating reflects the usual spread seen on premium aftermarket nozzles rather than a specific defect.
Where a carbide tip is justified
If you run abrasive ABS or ASA continuously across several machines, wear rate becomes a real cost, and a tip that outlasts several hardened steel nozzles changes the economics of the consumable. The conductivity figure also means less temperature compensation than steel needs, which saves retuning time.
For a single hobby printer doing occasional reinforced ABS, the spend does not pay back.
Who should skip it
Skip it if you only print smooth ABS, because brass will do the same job. It is an M6 MK8 part and will not fit V6, Volcano, Nextruder or Revo hotends, and with one nozzle in the pack you have no backup.
Nozzle Thread and Fitment Compatibility for ABS Printers
Fitment is the number one reason an otherwise perfect ABS nozzle ends up on a shelf, because MK8, V6, Volcano, Nextruder and Revo all look similar and none of them are interchangeable. Check the thread form before you order, not after.
MK8 and M6 is the most common thread in the hobby. It covers the Creality Ender 3, 3 V2, 3 Pro, 3 Max, 5 and S1 family, the CR-10, the Prusa i3 MK8 hotend, Anet A8 and A8 Pro, and most Reprap-style clones. Nearly every nozzle in this roundup is MK8.
V6 and M6 is a different form factor used on Prusa i3 MK3 and MK3S, Prusa Mini, LulzBot Taz6, Anycubic Mega and Flsun machines. V6 nozzles are longer and thread differently, so an MK8 nozzle will not seat. Our POLISI3D pick is the one here built for that hotend.
Volcano and V6 high-flow uses a much wider bore and a longer, wider body. It will not accept a standard nozzle at all, and a high-flow Volcano nozzle moves noticeably more melt per second, which matters for thick ABS walls. A dedicated high-flow nozzle is worth considering if you print large filled parts, but check that your hotend is a Volcano variant first.
Nextruder and Revo are toolchanger conventions where the nozzle is part of an extruder carriage rather than a screw-in part. Standard screw-in nozzles do not apply, and you need a nozzle made for that specific toolchanger. The Bambu A1, A1 Mini and A2L use a magnetic quick-swap assembly rather than a thread, while the H2D, H2S, H2C, X2D and P2S use their own quick-swap standard, so neither takes an MK8 nozzle.
One more physical check: nozzle length. Several owners across these reviews reported that a replacement nozzle was slightly longer or shorter than the factory part, which changes your Z offset and first layer height. Measure before you swap, and expect one adjustment on the first print.
ABS Settings That Pair With Your Nozzle Choice
Nozzle temperature for ABS typically sits between 235°C and 260°C. Start at 245°C for a first layer, then move in 5°C steps. If you are on hardened steel or tungsten carbide rather than brass, add roughly 5-10°C because steel pulls heat out of the melt zone faster.
Bed temperature should be between 90°C and 110°C on a heated bed, and the surface matters more than the number. A clean PEI or textured sheet with a suitable adhesive is the difference between a part that releases and one that welds itself to the bed.
Set the part-cooling fan to 0% for the first few layers, then no more than about 20% after that. Fan cooling is the enemy of ABS layer adhesion, and high fan speeds are a common cause of cracking and poor bonding.
An enclosure is effectively required. ABS warps because the part shrinks as it cools, and any draught or room temperature variation across the bed pulls corners upward. If your printer is open-frame, a properly fitted enclosure should be your first purchase after the nozzle. We covered the options in our enclosure roundup.
Print slower than you think you need to. ABS warps far less at reduced speed, and a steel nozzle benefits from the extra dwell time at the melt zone. If you move from brass to steel, drop outer wall speed a little and raise nozzle temperature at the same time.
How to Install and Break In a New ABS Nozzle?
Heat first. Bring the hotend up to printing temperature and hold it there while you work. A cold steel nozzle threaded into a cold heat break can be very slightly out of round, and tightening it cold leaves it out of round when heated, which is the classic cause of a leaking nozzle joint on ABS.
Thread the nozzle in by hand until it seats, then snug it only slightly. If your hotend has a V6 or MK8 screw-on design, a quarter turn past finger tight is usually enough. If your printer uses an M3 set screw across the flats, tighten the set screw against the nozzle first so the nozzle cannot rotate.
Hot-tighten at temperature. With the hotend at 245°C or above, give the nozzle another gentle turn. The heat break and nozzle expand together, and that expansion is what makes a threaded ABS joint stop leaking. Do this every time you swap a nozzle, not just the first time.
Check the first layer before committing to a long print. Run a single layer test and confirm the lines merge cleanly with no gaps and no ridges. If you see gaps, the nozzle is sitting too high; if you see ridges, it is too low. Adjust in small steps from there.
Prime and purge before the real print. Pull 200-300mm of filament through at printing temperature and wipe the tip with a cloth. A tip covered in old plastic is both a clog risk and the reason your first layers look rough.
Finally, run a temperature tower for the material at 5°C increments. This is quick, it takes one plate of space, and it shows you exactly where the layers stop bonding. Do it once with the new nozzle and note the number on the profile.
How to Spot a Worn Nozzle and Clear Clogs
Look at the tip under magnification. A new 0.4mm nozzle has a clean, round, bright opening. A worn one looks flattened on one side, oval, or has a visible burr ring around the bore. That is the bore widening, and it is what ruins dimensional accuracy and layer adhesion on long ABS parts.
Check the outside of the tip for scuffing and pitting, which happens faster on filler-loaded filament. Run a rigid cleaning needle through the bore from both directions. If it meets resistance, the bore is deformed and the nozzle is finished.
Watch the print, not just the first layer. A worn nozzle shows up as steadily growing gaps between walls, a rough or fuzzy ridge pattern, and corners that no longer match each other. On ABS, the same wear often shows up as layer splitting a few hours in.
To clear a clog without removing the nozzle, heat to printing temperature plus 10°C and push filament through by hand with a new 0.4mm needle. Do not use a needle smaller than the bore, and never force a blocked nozzle with cold filament, because that pushes the blockage further up toward the heat break.
If a needle will not pass, replace the nozzle rather than drilling it. A brass nozzle is cheap enough that this is not worth risking, and on a hardened nozzle a drill bit is a fast way to destroy the concentricity that made it worth buying.
Prevent clogs with a cold pull on the hotend silicone sock or PTFE-lined section, and keep the nozzle out of prolonged heat soak. If you are printing ABS at 250°C with a hardened nozzle, replacing the nozzle on a schedule based on filament hours is easier than diagnosing a failed part halfway through a 30-hour job.
Buying Guide: Choosing a Nozzle for ABS
Step one is material, and the split is simple. Smooth ABS and ASA on a home printer means brass is a legitimate choice, and brass gives you better conductivity and cleaner melt. Reinforced, filled or pigmented ABS means hardened steel, without exception. Continuous abrasive printing across several machines means tungsten carbide or ruby.
Step two is the thread. Confirm whether your hotend is MK8/M6, V6, Volcano, Nextruder, Revo or a Bambu quick-swap variant before you compare anything else. This single check eliminates most returns.
Step three is diameter. The standard 3D printer nozzle size is 0.4mm, and it handles 1.75mm filament, which is what nearly every desktop printer consumes. A 0.2mm nozzle is for fine detail, 0.6mm and 0.8mm are for speed and stronger layer bonding, and 1.0mm is for very thick, fast extrusion.
Step four is temperature rating. ABS at 235-260°C is well inside what any brass or steel nozzle handles, but the rating matters if you plan to run PEEK or other high-temperature polymers later. Options rated to 300°C or above give you that headroom.
Step five is build quality. Cheap clone hardened nozzles with off-centre or rough bores will produce uneven extrusion no matter how good the material is, and no amount of tuning fixes a bore that was never drilled straight. Look for stated diameter tolerance, a stated hardness figure such as HRC 60, and a seller with a clear return policy.
On diameter choice specifically, 0.4mm versus 0.6mm comes down to what you are making. 0.4mm is the safe default for general ABS work and gives better detail on complex geometry. 0.6mm prints faster, pushes more material, and bonds between layers more strongly, which helps on functional parts, at the cost of overhang quality and fine features.
On a final practical point: keep a spare. Nozzles are consumables, and a clog during a long ABS print is the most frustrating failure in the hobby. A brass spare costs almost nothing and turns a ruined plate into a short pause.
Frequently Asked Questions
What nozzle should I use for ABS?
For plain, unfilled ABS, a factory brass 0.4mm nozzle is the right choice, because brass conducts heat better than steel and gives cleaner melt at 235-260°C with less ooze. As soon as you add carbon fibre, fiberglass, glow pigment or mineral filler, move to a hardened steel nozzle, since those particles wear the bore and ruin layer adhesion on long prints. A tungsten carbide tip is only worth it for continuous abrasive printing across multiple machines.
Do I need a different nozzle for ABS?
Usually not. Plain ABS and ASA print happily through a standard brass nozzle at 235-260°C, and the standard brass nozzle that came with your printer is designed for that range. You do need a different nozzle if you print filled or reinforced ABS, because brass is a soft metal and the filler particles cut the bore from the inside. Switching from brass to hardened steel also means retuning: add about 5-10°C to the nozzle temperature and reduce part cooling.
Does ABS require a hardened nozzle?
Only for filled or reinforced ABS. Standard ABS has no abrasive particles, so brass lasts a very long time and conducts heat better. Carbon fibre, glass fibre, mineral-filled, wood-filled and glow-in-the-dark ABS all wear a brass bore, widening it over time and causing under-extrusion, stringing and layer splitting. Hardened steel resists that wear. Make sure the thread matches your hotend, since MK8 and V6 nozzles are not interchangeable.
What temperature should I print ABS at?
Start with a 245°C nozzle and a 100°C bed, then adjust in 5°C steps. A nozzle range of 235-260°C covers almost all ABS, and a bed between 90°C and 110°C keeps the first layer attached. Keep the part-cooling fan at 0% for the first few layers and no higher than about 20% afterwards, since fan cooling hurts ABS layer adhesion. An enclosure matters more than any of these numbers, because draught causes warping.
Is a 0.6mm or 0.4mm nozzle better for ABS?
For most ABS work, 0.4mm is the safer default because it handles fine detail and complex overhangs better. A 0.6mm nozzle prints faster, pushes more material per second and bonds between layers more strongly, which matters for thick functional parts and walls, but it costs detail on small features. Both accept standard 1.75mm filament. If you run reinforced ABS, move to hardened steel in whichever diameter suits the part rather than staying with brass.
Why does my ABS nozzle clog?
ABS oozes because it is printed well above the softening point of the heat break, and any filament that creeps into the hotend gap swells and blocks the bore. Steel and all-metal hotends reduce this compared with brass because there is no gap to fill. Other causes include a bore that is already worn or deformed, filament that has been left in the nozzle for days, and pushing cold filament into a blockage. Heat to printing temperature plus 10°C and clear with a rigid needle of the correct size.
How long does a hardened nozzle last with ABS?
For plain ABS, a hardened steel nozzle will comfortably outlast the original brass part and owners report running them for a year or more of regular use. Filled ABS shortens that considerably, since the abrasive particles are what wear the bore. Tungsten carbide lasts longest of the materials covered here, with a 9 Mohs hardness and a 550°C rating, at the highest cost per nozzle. Track filament hours rather than calendar time, since that is what drives wear.
Conclusion: Our ABS Nozzle Picks
For most people reading this, the answer is narrower than they expect. If you print plain ABS or ASA on an Ender, a Creality or CR-10, take the factory brass path: the Creality OEM pack is the highest rated option and fits exactly as designed, while the Comgrow 25-piece set is the better buy if you run more than one machine or want a spare at the printer.
If any filler enters the picture, the best 3d printer nozzles for abs come down to hardened steel. The Mudder MK8 set is our top pick for abrasive material on MK8 Ender and CR-10 hotends, the Creality multi-size hardened pack covers every diameter from 0.2 to 1.0mm in one box, and the POLISI3D set is the one to buy if your hotend is a Prusa V6 rather than an MK8.
On the newest machines, the fitment rules change completely. The HzdaDeve kit covers the Bambu A1, A1 Mini and A2L, and the SAHVAIM pack covers the H2D, H2S, H2C, X2D and P2S. Neither takes a standard screw-in nozzle, and neither will work on an Ender or a Prusa.
Whatever you pick, hot-tighten it at temperature, run a first layer test, and change it when the bore starts to oval. That habit matters more for ABS than the material of the nozzle itself. If you are still building out your setup, our 3D wall panel guide covers the finishing side once parts come off the plate.
