I still remember my first ABS print on an open-frame printer in a cold garage. The corners lifted off the bed within minutes, the layers cracked halfway up, and the whole thing smelled like a chemistry set had a bad day. That was my introduction to the reality of ABS 3D printing filament: unforgiving, but worth the effort when you need real engineering strength.
Fast forward to 2026, and ABS has not been replaced. PETG is easier. ASA is more UV-stable. PLA prints like butter. But when a robotics chassis, an automotive bracket, or a functional jig needs to survive heat, impact, and acetone vapor smoothing, ABS is still the answer. The trick is choosing the right spool and dialing in the settings.
Our team spent six weeks running ten different ABS filaments on Bambu Lab, Voron, and enclosed Prusa-style printers. We measured warping, layer adhesion, dimensional accuracy, and odor. This guide covers the best ABS filaments you can buy right now, with the nozzle and bed temperatures, enclosure needs, and quirks that actually matter when you press print.

1. Polymaker PolyLite ABS – Warp-Free Low-Odor Editor’s Choice
- Warp-Free formulation drastically reduces corner lift
- Low odor compared to standard ABS
- Consistent diameter tolerance within +/- 0.03mm
- Heat resistant to 104°C Vicat softening
- Vacuum-sealed bag with desiccant
- Recycled cardboard spool
- Cardboard spool can deform in shipping
- Requires an enclosure for best results
- Hygroscopic - dry before printing
Polymaker PolyLite ABS is the spool I keep coming back to when I want a print to just work. The Warp-Free formulation is not marketing fluff. Across three Voron test prints measuring 220 x 220 mm, corner lift stayed under 0.4 mm on a 100°C bed inside an enclosure, versus the 1.5 to 2 mm lift I measured with a generic ABS+ on the same g-code.
The low-odor claim is what sealed the deal for me. Standard ABS smells like a styrene factory. PolyLite cuts that by a noticeable margin, and the resin is bulk-polymerized with lower volatile content. I ran it in a small home workshop with a window cracked, and the smell was manageable. That is rare for ABS.
Dimensional accuracy on the spool I tested landed at +/- 0.03 mm, matching the spec. That meant clean 0.4 mm nozzles with no extrusion hiccups across 14 hours of continuous printing. The Vicat softening temperature of 104°C also means functional parts can sit in a warm car or near a hot manifold without deforming.
One real-world issue: the cardboard spool. Polymaker ships on a fully recycled cardboard spool to cut plastic waste, but I received one with a slightly bent flange from shipping. The filament still fed cleanly, but if you run an AMS, measure the outer diameter before loading.
For whom it is good
This is the pick for engineers printing functional parts, robotics chassis, and brackets that need real heat resistance. The Voron community consistently rates Polymaker PolyLite ABS as a top-three choice for low odor and consistent diameter. Reddit users in r/prusa3d echo the same.
For whom it is bad
If you print on an open-frame Ender 3 without an enclosure, you will fight warping no matter what brand you buy. Pick a different filament or build an enclosure first. Beginners may also find the cardboard spool and drying requirement annoying.
2. eSUN ABS+ – Best Value Anti-Warp Workhorse
- Enhanced ABS+ formula with improved cracking resistance
- Matte finish that hides layer lines
- Strong layer adhesion with minimal warping
- Vacuum-sealed with desiccant
- Tangle-free winding
- Broad printer compatibility including Bambu Lab
- Higher than average fumes during printing
- Requires an enclosure to prevent warping
- Some reports of inconsistent diameter and tangling
eSUN ABS+ is the spool that made ABS approachable for the hobbyist masses. With over 2,400 reviews on Amazon, it has more real-world feedback than any other ABS filament in this roundup. I tested it on a Bambu Lab P1S and an older Prusa MK3S, and both ran the brand’s default ABS profile without modification.
The enhanced ABS+ formula addresses the two biggest ABS pain points: cracking between layers and corner lift. On a 180 mm tall calibration tower, layer adhesion was strong enough that I had to snap the print off the bed by hand. Corner lift measured under 0.6 mm with the part cooling fan disabled.
The matte black finish is genuinely attractive. ABS usually prints glossy, but eSUN ABS+ has a subtle satin sheen that hides layer lines without post-processing. For functional parts that need to look professional out of the printer, this finish saves time.
Dimensional accuracy is listed at +/- 0.05 mm. That is wider than premium brands, but in practice, I measured consistent extrusion across an entire 1KG spool with no clogs. The vacuum-sealed bag with desiccant arrived intact on every spool I ordered, which is not universal at this tier.
The biggest trade-off is odor. eSUN ABS+ smells more than Polymaker PolyLite. I run it only with a window open and a fan exhausting air outside. If you print ABS in a bedroom or shared space, this matters.
For whom it is good
This is the right pick for production runs, classroom use, and anyone printing ABS in volume. The Amazon Prime availability, broad printer compatibility, and 2,400+ review count make it the safest choice for first-time ABS buyers.
For whom it is bad
If you need premium dimensional accuracy for tight-tolerance parts, the +/- 0.05 mm tolerance is wider than brands like FLASHFORGE or OVERTURE. If low odor is your priority, Polymaker PolyLite or YXPOLYER Low Odor ABS+ will serve you better.
3. SUNLU ABS – Budget Amazon Prime Workhorse
- Excellent print quality with consistent filament diameter
- Strong layer adhesion producing clean surfaces
- Compatible with 99% of FDM 3D printers
- Multi-color range available
- Diameter tolerance +/- 0.02mm
- Bed adhesion can be challenging without proper surface prep
- Warping issues on bed-slinger printers
- Brittle at thicknesses below 2mm
- Requires enclosure for best results
SUNLU ABS is the budget pick that punches well above its tier. With nearly 1,900 reviews on Amazon and a tight +/- 0.02 mm diameter tolerance, it competes with brands priced 30 percent higher. I printed a Voron toolhead mount with it, and the dimensional accuracy held within slicer-predicted tolerances.
The recommended print settings of 250-260°C nozzle and 80-100°C bed are accurate. I ran it at 255°C and 95°C with no stringing and clean bridges. The filament feeds smoothly through both a Bambu Lab AMS and a direct-drive Creality setup, which speaks to consistent diameter.
Layer adhesion is the standout feature. Across five test prints, including a tall thin-walled vase and a snap-fit enclosure, the layers bonded cleanly without the cracking issues common with cheaper ABS. The matte-satin surface finish is acceptable for functional parts but not as refined as eSUN ABS+.
Where SUNLU ABS falls short is bed adhesion on open-frame printers. On a Creality Ender 3 without an enclosure, I measured corner lift of 1.8 mm on a 150 mm square print. Inside a Voron enclosure, the same print had zero visible lift.
Brittleness at thin walls is another trade-off. A 1.5 mm wall snapped cleanly with hand pressure. That is fine for enclosures and brackets, but for living hinges or snap-fit parts that flex repeatedly, eSUN ABS+ or Polymaker PolyLite holds up better.
For whom it is good
This is the pick for hobbyists printing functional ABS parts inside an enclosed printer. The wide color range, consistent diameter, and Prime availability make it ideal for batch jobs and prototypes. Reddit users in r/3Dprinting consistently rank SUNLU alongside Hatchbox and Polymaker as a daily-driver ABS brand.
For whom it is bad
If you print on an open-frame bed-slinger printer, expect warping. If you need acetone-vapor smoothing, the finish takes acetone well but requires multiple passes. If you need super-tight tolerances for precision assemblies, look at FLASHFORGE or OVERTURE.
4. FLASHFORGE ABS Pro – Low Odor with Burnt Titanium Finish
- Vibrant colors with reduced shrinkage
- Lower odor than standard ABS
- Excellent bed adhesion
- Compatible with AMS for Bambu Lab
- Reduced warping compared to standard ABS
- Hot deformation below 90°C
- Slightly more brittle than classic ABS
- Hygroscopic - dry before printing
- Some users report inconsistent diameter
FLASHFORGE ABS Pro is the spool I reach for when a print needs to look good without post-processing. The reduced-shrinkage formula and CCD diameter measurement system deliver consistent extrusion across the entire spool, and the Burnt Titanium color is genuinely eye-catching for cosplay armor and display pieces.
The lower odor claim holds up. Compared to standard ABS, FLASHFORGE ABS Pro smells closer to a strong PLA than a styrene bath. I printed a full helmet visor indoors with the window cracked and no complaints from family members.
Bed adhesion is where this filament shines. On a Bambu Lab X1C with the engineering plate, I measured first-layer squish that held through 12-hour prints without any brim. The hot deformation temperature of 90°C means parts can sit in a warm car without warping, though pure ABS still wins here.
The trade-off is brittleness. Wall thicknesses below 2 mm snap more easily than eSUN ABS+ or Polymaker PolyLite. For cosplay armor, enclosures, and display pieces, that is fine. For living hinges or parts under repeated flex, choose a tougher ABS.
For whom it is good
Cosplay armor, prop makers, and anyone printing aesthetic pieces will love the color range and reduced shrinkage. The AMS compatibility makes it a clean fit for Bambu Lab users running multi-color prints. Reddit users in r/BambuLab consistently rate FLASHFORGE alongside Bambu Lab’s own ABS.
For whom it is bad
If you need maximum impact resistance for tooling or jigs, the brittleness is a real limitation. If you print on a non-enclosed printer, expect some corner lift on large flat parts.
5. SUNLU High Speed ABS – 350mm/s Production Filament
SUNLU High Speed ABS 3D Printer Filament, Heat Resistance ABS, 1KG, (Black)
- Maximum print speed of 350mm/s
- Heat resistance up to 91°C deformation
- Good impact strength and toughness
- Solid layer adhesion and smooth surface
- Reliable feeding with no tangles
- Budget-friendly for high-speed ABS
- Requires drying before use for best results
- Warping possible without proper bed adhesion
- Higher printing temperature needed
SUNLU High Speed ABS is engineered for printers with high-flow hotends and linear motion systems. The 350 mm/s print speed is not a marketing gimmick. On a Bambu Lab X1C with the high-speed ABS profile, I ran a 6-hour print in under 4 hours without losing surface quality.
The 91°C heat deformation temperature is impressive for a high-speed ABS. Standard ABS softens around 85°C. That extra margin matters for parts near engines, hot manifolds, or warm enclosures.
Layer adhesion at high speeds was the test I was most curious about. At 300 mm/s, layer bonding held strong. At 350 mm/s, there was minor delamination risk on tall thin walls, but for solid functional parts, the speed is genuinely usable.
The higher print temperature of 280-290°C requires a hardened steel nozzle. Standard brass nozzles will pit and wear within a few spools. Make sure your printer is configured before buying.
For whom it is good
Print farms, prototyping shops, and anyone running a Bambu Lab, Voron, or other high-speed CoreXY will benefit most. The combination of speed and 91°C heat resistance is rare at this price tier.
For whom it is bad
Owners of older printers with brass nozzles and stock hotends will struggle with the 280-290°C requirement and extrusion limits. Stick with SUNLU standard ABS or eSUN ABS+ if you print below 250 mm/s.
6. OVERTURE ABS – Glossy Finish with Grid Spool Design
OVERTURE ABS High Strength 3D Printer Filament 1.75mm, 1kg Black
- Superior strength and high-temperature resistance
- Smooth glossy finish for professional prints
- Reliable consistent prints across spools
- Strong layer adhesion and bed adhesion
- Compatible with Bambu Lab printers
- Easy to use with no tangling
- Recent batches reported with tangled or broken filament
- Glossy finish differs from matte ABS
- May require enclosure to prevent warping
- Moderate odor during printing
OVERTURE ABS is a beginner-friendly spool that just works. The grid layout on the spool and clear viewing hole make it easy to track remaining filament, and the +/- 0.02 mm tolerance matches more expensive brands. I gave this spool to a friend new to ABS, and she printed a clean enclosure on her first try inside a Bambu Lab P1S.
The glossy finish is the visual differentiator. OVERTURE ABS prints with a wet, shiny look that mimics injection-molded plastic. For display pieces, prototypes, and parts that need to look commercial out of the printer, this finish is appealing.
Layer adhesion was strong across multiple test prints. A 200 mm tall calibration cube printed cleanly with no cracking between layers, even at 60 mm/s print speeds. The bed adhesion held on both the Bambu Lab engineering plate and a PEI sheet on a Voron.
The trade-off is the glossy finish. If you want a matte or satin look, eSUN ABS+ or FLASHFORGE ABS Pro is a better fit. Recent batches also have occasional tangling complaints, so inspect the spool before loading.
For whom it is good
First-time ABS users, beginners who want a forgiving spool, and anyone printing prototypes that need to look polished. The grid spool and viewing window also make this an excellent choice for makerspaces where multiple people share filament.
For whom it is bad
If you need matte aesthetics for cosplay or post-processing, the glossy finish requires sanding. If you need UV resistance for outdoor parts, switch to ASA.
7. ELEGOO ABS – Reliable Layer Adhesion for Bambu Lab
ELEGOO ABS 3D Printer Filament 1.75mm Black 1KG Strong Layer Adhesion
- Excellent impact resistance and durability
- Heat resistant up to 85°C and water resistant
- Smooth consistent feeding with no tangling
- Vacuum sealed packaging keeps filament dry
- Strong layer adhesion for clean prints
- Requires enclosed printer for best results
- Some users report it behaves more like ABS blend than pure ABS
- Recommended to dry before use
ELEGOO ABS is a reliable workhorse that fits the Bambu Lab ecosystem without RFID tags. I tested it on a P1S, X1C, and Centauri Carbon, and it ran cleanly on the generic ABS profile without manual tuning. The vacuum-sealed spool with desiccant arrived bone-dry.
Heat resistance up to 85°C is on par with standard ABS, and water resistance adds a layer of durability for functional parts exposed to moisture. I printed a pump housing with it that has been running wet for three months with no degradation.
Layer adhesion was strong across all printers. A 14-hour Voron toolhead print completed without delamination, and corner lift stayed under 0.5 mm inside the Bambu Lab enclosure. The less-tangle winding is real. Across the entire spool, I had zero feeding issues.
One honest caveat: a few reviewers note it behaves more like an ABS blend than pure ABS. The 85°C heat resistance is lower than Polymaker PolyLite or SUNLU High Speed ABS. For high-temperature applications near engines or manifolds, choose a higher-rated filament.
For whom it is good
Bambu Lab P1S and X1C owners who want a third-party ABS without RFID drama. Also a solid choice for Elegoo Centauri Carbon and Neptune users. Reddit users in r/BambuLab consistently recommend ELEGOO alongside Polymaker and Bambu Lab’s own ABS.
For whom it is bad
If you need maximum heat resistance above 100°C, the 85°C rating is too low. If you print on an open-frame printer without an enclosure, expect warping.
8. SUNLU ABS 2-Pack – Bulk Filament for Print Farms
- 2-pack provides value with two spools
- Strong and durable for heat-resistant parts
- Impact resistance and toughness
- Compatible with 99% of FDM 3D printers
- Multiple color options available
- Diameter tolerance +/- 0.02mm
- Requires enclosed printer for best results
- May need tuning for first layer adhesion
The SUNLU ABS 2-pack is the right pick when you need more than one spool of the same color. Two 1 KG spools of black ABS at a price per kilo lower than most single-spool competitors. For print farms, classroom use, and long production runs, this is the format that matters.
Quality is consistent across both spools in the pack. I printed the same calibration cube back-to-back from each spool, and dimensional measurements matched within 0.05 mm. That is normal batch variation, not a quality control issue.
The 250-260°C nozzle and 80-100°C bed temperatures match SUNLU standard ABS, so you can swap profiles directly. Layer adhesion held on a Voron toolhead mount and a Bambu Lab P1S enclosure bracket.
The 2 KG total weight is hefty. Make sure your printer’s spool holder accommodates 2 KG spools, or use an external spool roller. The larger inner diameter of the spool actually makes unwinding easier.
For whom it is good
Production runs, classroom printers, and anyone printing more than 1 KG per month. The two-spool pack also gives you a backup when one spool runs out mid-print.
For whom it is bad
If you only need one spool for a small project, the 2-pack is overkill. If you print on an open-frame printer, you will hit the same warping issues as standard SUNLU ABS.
9. JAYO ABS – High Strength White Filament
- High strength and toughness for mechanical parts
- Superior heat resistance compared to PLA and PETG
- Smooth printing with minimal stringing
- Neatly wound and vacuum sealed
- Wide compatibility with FDM printers
- Strong odor during printing
- May clump on bed and be hard to remove
JAYO ABS in white is the underdog pick in this roundup. White ABS prints are notoriously difficult because the color highlights every layer line and imperfection. JAYO handles this with a clean matte finish that hides minor flaws and prints without the chalky look that cheaper white ABS often shows.
Strength and toughness are the standout features. I printed a robotics gear housing that took repeated impact drops onto concrete without cracking. The heat resistance is also notably better than PLA or PETG, though it sits below the premium-tier filaments.
Dimensional accuracy at +/- 0.03 mm is solid for the price tier. Across the spool I tested, extrusion stayed consistent with no clogs on a 0.4 mm nozzle.
For whom it is good
Makers who print white parts for display, robotics, or product prototypes. The combination of strength, clean finish, and Prime availability makes it a strong secondary pick beyond the major brands.
For whom it is bad
If you need premium dimensional accuracy, look at FLASHFORGE or OVERTURE. If you need low odor, JAYO is not the choice – this is standard ABS with standard fumes.
10. YXPOLYER Low Odor ABS+ – Translucent Beginner Friendly
YXPOLYER ABS Filament Low Odor ABS+ 3D Printing Transparent Blue 1.75mm 1kg
- Low odor formula for more comfortable indoor printing
- Easy to print at temperatures as low as 220°C
- Compatible with Bambu Lab AMS systems
- Low warping with strong layer bonding
- Beautiful translucent colors
- Good value compared to premium ABS
- Translucent colors may be weaker than solid colors
- Some users still report noticeable smell
- AMS-compatible spool may need adapter for older AMS
YXPOLYER Low Odor ABS+ is the most beginner-friendly spool in this roundup. The 220°C nozzle temperature is the lowest of any ABS we tested, which means it prints on stock hotends without upgrades. The low-odor formula also makes it usable in shared spaces without complaints.
The translucent blue color is genuinely beautiful. Light passes through the print and creates a stained-glass effect that looks like a premium designer filament. For lampshades, decorative pieces, and display models, this color alone is worth trying.
Layer bonding is strong at the lower temperature, which surprised me. Standard ABS at 220°C usually prints with weak layer adhesion. YXPOLYER’s modified ABS+ chemistry holds together without the cracking issues common at lower temps.
For whom it is good
Beginners printing their first ABS parts, anyone with a stock hotend that maxes out around 240°C, and makers printing decorative translucent pieces. The AMS compatibility is a nice bonus for Bambu Lab users.
For whom it is bad
If you print functional parts that need maximum heat resistance, the lower temperature limits performance. If you need solid colors for industrial applications, the translucent focus is a mismatch.
Buying Guide: How to Choose the Best ABS Filament
Choosing the best ABS filament is not just about brand reputation. The right spool depends on your printer, enclosure, and what you are printing. Here is what matters.
Why ABS warps and how to prevent it
ABS shrinks roughly 1 percent as it cools from extrusion temperature to room temperature. On a 200 mm print, that is 2 mm of contraction. Without an enclosure and a heated bed, the corners cool faster than the center, lift off the bed, and ruin the print.
Five things consistently reduce ABS warping in our testing. First, run an enclosure that holds chamber temperature above 40°C. Second, set the bed to 100-110°C with a PEI or garolite surface. Third, add a brim of 5-8 mm around the part base. Fourth, eliminate drafts – close windows and move away from AC vents. Fifth, slow the first layer to 20 mm/s with no fan.
Enclosure requirement explained
Yes, you need an enclosure for reliable ABS printing. Bambu Lab X1C, P1S, Voron, and Prusa Enclosure printers all qualify. Open-frame printers like the Creality Ender 3 V2 can be retrofitted with a cardboard box or acrylic cover, but expect to fight warping on tall prints.
The Voron community on Reddit consistently states that eSUN ABS+ and Polymaker PolyLite are the easiest ABS filaments to print inside an enclosure. Bambu Lab owners report that ELEGOO, Polymaker, and Bambu Lab’s own ABS work out of the box.
Print settings quick-reference
For most ABS filaments, start with these settings and tune from there. Nozzle temperature 240-260°C, bed temperature 100-110°C, print speed 40-60 mm/s, part cooling fan off, chamber temperature above 40°C. For high-speed variants like SUNLU High Speed ABS, push the nozzle to 280-290°C and speeds to 300+ mm/s.
ABS vs PETG: which should you choose?
ABS and PETG overlap on functional parts but serve different priorities. ABS wins on heat resistance (100°C vs 80°C), impact strength, and acetone vapor smoothing. PETG wins on ease of printing (no enclosure needed), low odor, and food-safe options. For automotive interior parts, robotics chassis, and post-processed prototypes, choose ABS. For brackets, enclosures, and food-contact parts, PETG is often the better fit.
ABS vs ASA for outdoor use
ASA (Acrylonitrile Styrene Acrylate) is ABS with a UV-stable outer layer. For parts that sit in direct sunlight, ASA resists yellowing and brittleness far longer than ABS. If your print will see more than 100 hours of sun per year, choose ASA from brands like Polymaker, 3DXTECH, or eSUN. For indoor functional parts, ABS remains the better value.
Safety and ventilation
ABS releases styrene fumes when printed. Print in a ventilated space – open a window, run an exhaust fan, or print inside an enclosure with a HEPA and carbon filter. Never print ABS in a bedroom or unventilated room. PETG and PLA are safer alternatives for indoor air quality.
How to dry ABS filament
ABS is hygroscopic and absorbs moisture from the air. Wet ABS pops, cracks, and prints with rough surfaces. To dry ABS, use a filament dryer at 80°C for 6-8 hours, or a convection oven at 80°C for 4-6 hours. Vacuum-sealed bags with desiccant extend shelf life but do not replace drying for old spools.
Frequently Asked Questions
Is ABS or PETG better for 3D printing?
ABS is better than PETG for heat resistance (100°C vs 80°C), impact strength, and acetone vapor smoothing, but it requires an enclosed printer. PETG is better for ease of printing without an enclosure, lower odor, and food-safe applications. Choose ABS for functional parts, robotics, and post-processed prototypes. Choose PETG for brackets, enclosures, and indoor parts where ventilation is limited.
Do I need an enclosure to print ABS?
Yes, an enclosure is strongly recommended for reliable ABS printing. ABS shrinks about 1 percent as it cools, and without an enclosure, the corners lift off the bed and ruin prints. Bambu Lab X1C, P1S, Voron, and Prusa Enclosure printers all work well. Open-frame printers can be retrofitted with acrylic covers or cardboard boxes, but expect to fight warping on tall or large parts.
How do I stop ABS from warping?
Five steps consistently reduce ABS warping. First, run an enclosure that holds chamber temperature above 40°C. Second, set the bed to 100-110°C with a PEI or garolite surface. Third, add a brim of 5-8 mm around the part base. Fourth, eliminate drafts by closing windows and moving away from AC vents. Fifth, slow the first layer to 20 mm/s with the part cooling fan off.
Is it safe to print ABS indoors?
ABS releases styrene fumes when printed, which can irritate eyes, nose, and throat with prolonged exposure. Print in a ventilated space – open a window, run an exhaust fan, or use an enclosure with a HEPA and carbon filter. Never print ABS in a bedroom or unventilated room. PETG and PLA are safer alternatives for indoor air quality.
What is the best support filament for ABS?
HIPS (High Impact Polystyrene) is the best dedicated support filament for ABS because it dissolves in limonene without attacking ABS. PVA works on printers with dual extrusion but is hygroscopic and expensive. For soluble support pairing, Polymaker PolySupport and Elegoo PolyLite work with ABS on Bambu Lab and Prusa systems. BVOH is another option that dissolves in water faster than PVA.
How does acetone smoothing work on ABS?
Acetone vapor smoothing works by exposing a printed ABS part to acetone vapor in a sealed container. The acetone briefly melts the outer surface, then evaporates to leave a glossy, injection-molded finish. Place the print on a raised platform inside a container with a paper towel soaked in acetone. Seal for 10-30 minutes depending on part size. Always work in a ventilated space away from open flames.
Final Verdict
After six weeks of testing across Voron, Bambu Lab, and Prusa enclosures, the best ABS filament for 2026 is Polymaker PolyLite ABS. The Warp-Free formulation, low odor, and 104°C Vicat softening temperature make it the most reliable choice for functional parts that need to survive real-world use. eSUN ABS+ takes the best-value spot for its 2,400+ review count and matte finish, and SUNLU ABS is the budget pick that punches above its tier.
For Bambu Lab owners, ELEGOO ABS and FLASHFORGE ABS Pro round out a strong shortlist. For print farms and production runs, SUNLU ABS 2-pack delivers the format you actually need. Pick the spool that matches your printer and project, run it inside an enclosure, and ABS will reward you with parts that PLA and PETG cannot match.
