Extruder requirementNot documented0.6 mm nozzle recommended by Bambu Lab; 0.4 and 0.8 also supported[4]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[19]Hardened steel required — Polymaker measures brass nozzle life at about 9 h on PA6-GF25 and recommends hardened steel or ruby[3]
Abrasiveness1–5Non-abrasive[19]Highly abrasive — standard GF composite; Polymaker puts brass nozzle life at roughly 9 h on PA6-GF25[3]
Nozzle clog risk1–5Low — no special hot-end required and clogging is not among the listed drawbacks; Prusa lists no drybox and no hardened nozzle[24][25]Very high — frequent jams without careful setup[23]
Heat-creep / jam sensitivity1–5Slightly sensitive[24]Moderate — good heatbreak cooling needed[20]
Hotend requirementNo special hot-end required[24]May require an all-metal hot end (Simplify3D)[20]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate — 0.65 % saturated at 25 °C / 55 % RH (Bambu Lab); Polymaker measures 0.51 % maximum uptake for ABS Pro[5][6]Very high (>2 %) — 2.56 % saturated at 25 °C / 55 % RH (Bambu Lab) and 3.33 % equilibrium (Polymaker Fiberon), the highest in the dataset[4][3]
Equilibrium moisture content at ~50 % RH%0.65 saturated at 25 °C / 55 % RH (Bambu Lab); 0.51 maximum (Polymaker ABS Pro)[5][6]2.56 saturated at 25 °C / 55 % RH (Bambu Lab); 3.33 equilibrium (Polymaker Fiberon PA6-GF25)[4][3]
Drying temperature & time80 °C for 8 h (Bambu Lab); 70 °C for 6 h (Polymaker)[5][1]80 °C for 8–12 h (Bambu Lab)[4]
Symptoms when wetBubbling and popping at the nozzle, stringing, rough surface and weak layers[23]Popping and cracking during extrusion, then hard-to-diagnose defects[26]
Effect of moisture on strengthPolymaker rates ABS moderate-sensitivity and publishes no dry-versus-conditioned figures; the loss appears as poor layer adhesion and surface defects rather than a stated strength delta[23]Polymaker publishes dry and wet printed blocks for PA6-GF25 itself: at 4.57 % moisture tensile falls 80.1 → 40.2 MPa and modulus 5357 → 1794 MPa, while notched Charpy rises 10.0 → 28.0 kJ/m²[3][26]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity and advises periodic drying in humid climates[23]Sealed below 20 % RH with desiccant[23]
Hydrolysis at melt temperatureNot documentedPolymaker specifies an 80–100 °C dry and storage below 20 % RH; no molecular-weight loss figure is published, and the wet data it does publish is conditioning rather than melt hydrolysis[27][28]

Flexural strengthMPa60 (ABS Pro) to 63 (ABS Max) printed XY, ISO 178; Bambu Lab 62 ± 4; 3DXTech quotes 76[5][6][7][29]Not documented
Flexural modulusMPa1880 ± 110 (Bambu Lab) to 2500 (ABS Max) printed XY, ISO 178[5][7]3670 ± 140 printed XY, ISO 178 (Bambu Lab)[4]
Charpy impact, notchedkJ/m²10.5 (ABS Max) and 14.5 (ABS Pro) printed XY, ISO 179, notched; PolyLite ABS 18.0 ± 0.9 and Bambu Lab 21.5 ± 2.2[1][6][7][5]10.0 ± 0.7 printed XY dry and 28.0 ± 1.0 conditioned, ISO 179 notched (Polymaker Fiberon); Bambu Lab 7.2 ± 2.3[3][4]
Other impact dataCharpy unnotched 39.3 ± 3.6 printed XY (Bambu Lab, ISO 179); notched 21.5 ± 2.2[5]Charpy unnotched 27.2 ± 2.2 printed XY (Bambu Lab, ISO 179). Stratasys FDM PA6/66-GF30-FR gives Izod notched 74.6-77.1 J/m printed XZ against 17.2-22.1 in ZX (ASTM D256)[4][30]

Creep resistance / sustained load1–5Moderate — no printed-ABS creep test found; Tg of 101–126 °C keeps room-temperature service far below softening, unlike PLA[1][6][7]Good. Ensinger lists high creep resistance as a headline property of extruded PA66-GF30 stock; the rating is held below Excellent because equilibrium moisture uptake of 3.33 % softens the matrix in service[31][3]
Fatigue / repeated-flex resistance1–5Moderate — no printed-ABS S-N curve found; 10.5 % elongation and 21.5 kJ/m² notched Charpy give far more cyclic tolerance than PLA[5][32]Good. Ensinger lists high fatigue strength as a headline property of extruded PA66-GF30 stock[31]
Elasticity / flexibility1–5Rigid[5]Rigid[4]

Flammability / UL 94Flammable; no UL 94 rating published for standard ABS, though V-0 grades exist[36][5]Flammable; no UL 94 rating published for the grades surveyed[27]
Environment & Chemical
UV resistance1–5Months outdoors before embrittlement[18]Months outdoors before embrittlement — unstabilised polyamide yellows under UV[21]
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; poor against strong acids; dissolved by acetone[1]Withstands oils, fuels and alkalis[21]
Water / humidity resistance in service1–5Good — minor absorption[5]Absorbs water, properties shift[26]
Food contactNot food safe — Polymaker cites potential chemical leaching[18]Not food-contact certified as filament[21]
Biodegradability / compostabilityNot biodegradable[18]Not biodegradable[21]
RecyclabilityMechanically recyclable as resin code 9, but not accepted in household plastic collection[18]Not accepted in household plastic collection[21]
Electrical & ESD propertiesSurface resistance above 10¹³ ohm/sq — insulating (3DXTech, ASTM D257)[29]Surface resistivity above 10¹² ohm — insulating (Polymaker Fiberon, ANSI/ESD S11.11)[3]
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[37][19]Moderate — measurable VOCs and UFPs, ventilation advised[37]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[37]Up to 180 caprolactam, the dominant VOC from nylon and the largest single-VOC rate in the study[37]
Ultrafine-particle emission rateparticles/min2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[37]≈2 × 10⁸ median for nylon — low for particles despite the highest VOC mass measured[37]
Hazardous species emittedStyrene dominates. Bambu Lab states ABS and ASA release harmful gases such as styrene at printing temperature, which can be toxic and cause dizziness or nausea[37][19]Caprolactam, at up to 180 µg/min from nylon filament[37]
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[37][19]Ventilated room or enclosure recommended[37]
Dust & fibre handling hazardNot documentedGlass fibre is bound in the matrix; avoid inhaling sanding dust[3]
Post-Processing
Sanding & machiningSands well and takes filler; the usual preparation before painting[18]Sands poorly — gums rather than powders[20]
Gluing & solvent weldingSolvent-welds with acetone[1]Cyanoacrylate; no common solvent welds polyamide[20]
Vapour / chemical smoothingAcetone vapour smoothing works — ABS dissolves in acetone[1]No practical vapour smoothing[20]
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[38][19]Not documented
Dimensional accuracy & detailWarping and cooling-stress cracking are the accuracy limits, not shrinkage of the melt[19]Not documented
Solvents & Solubility
Soluble inAcetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[39][1]Formic acid, phenol, m-cresol and hexafluoroisopropanol dissolve the matrix at 23 °C, leaving the fibre; laboratory reagents.[40]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[39][41]Zinc chloride solutions stress-crack the nylon matrix, alcoholic calcium chloride dissolves it, mineral acids attack it.[40]
Solvent welding & smoothing agentAcetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[42]None — nylon's only solvents (formic acid, phenol, HFIP) degrade the part, and the fibre blocks surface flow anyway.[40]
