Typical applicationsLarge enclosure and automotive parts where plain ABS warps or softens too early[1][2]Dimensionally stable functional parts, ducting and living hinges where PA6 would move too much with humidity[4][13]
Printing Parameters
Nozzle temperature°C270–290 (ABS Pro); 270–300 (ABS Max) — 25–35 °C above plain ABS[1][2]260–290 (Extrudr DURAPRO PA12)[14]
Bed temperature°C120 (ABS Max)[2]110 (Extrudr DURAPRO PA12)[14]
Enclosure / chamber requirement1–5Enclosure required (passive)[1][2][15]Enclosure required (passive)[4]
Part cooling fanNot documentedPart cooling fan not required (Simplify3D)[16]
Bed surface & adhesion aidClean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[15][17]PEI sheet with a glue stick, or a dedicated adhesive such as Magigoo[16][4]
Maximum volumetric flow (mm³/s; see test conditions)mm³/sUp to 250 mm/s (ABS Pro) and 200 mm/s (ABS Max), equivalent to 20 and 16 on a 0.4 mm nozzle at 0.2 mm layer[1][2][18]12 at Extrudr's 150 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[14][18]
Warping tendency1–5High — enclosure needed for reliable large parts[15]Not documented
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[15]Needs a specific surface plus adhesive[16][4]
Stringing / oozing tendency1–5Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[19]Moderate — retraction tuning needed[4]
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile; the hotter nozzle rules out PTFE-lined hotends[1][2]Advanced — enclosure, hardware upgrades, tuning[4]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[15]Brass fine indefinitely for unfilled grades[4]
Abrasiveness1–5Non-abrasive[15]Non-abrasive when unfilled[4]
Nozzle clog risk1–5Low — unfilled ABS compound; no special hot-end required and clogging is not among the listed drawbacks[17][20]High — jams from moisture, heat creep or particles[13][21]
Heat-creep / jam sensitivity1–5Slightly sensitive[17]Moderate — good heatbreak cooling needed[16]
Hotend requirementNo special hot-end required[17]May require an all-metal hot end (Simplify3D)[16]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate — 0.51 % maximum water absorption (ABS Pro)[1]High (0.8–2 %) — Polymaker's PA12-CF10 reaches 1.5 % equilibrium against 3.33 % for its PA6-GF25, and Polymaker developed the PA12 grade specifically for lower moisture sensitivity[5][13]
Equilibrium moisture content at ~50 % RH%0.51 maximum water absorption (Polymaker ABS Pro)[1]Not documented
Drying temperature & time70 °C for 6 h (ABS Max)[2]60–80 °C for 8–12 h (Extrudr DURAPRO PA12); 100 °C for 8 h (Polymaker CoPA)[14][22]
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[21]Popping and cracking during extrusion, then hard-to-diagnose defects[13]
Effect of moisture on strengthPolymaker rates ABS moderate-sensitivity and publishes no dry-versus-conditioned figures[21]Polymaker states its PA12 grade changes little between wet and dry, unlike its PA6-based materials; the CoPA dry-to-wet reference shows what the PA6-type response looks like[13][22]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity[21]Sealed below 20 % RH with desiccant[21]
Hydrolysis at melt temperatureNot documentedPolymaker requires a 100 °C dry for 8 h and storage below 20 % RH; no molecular-weight loss figure is published, and the published wet data is conditioning rather than melt hydrolysis[22][23]
Mechanical Properties

Brittleness1–5Tough — absorbs impact, yields before breaking[1][2]Tough — absorbs impact, yields before breaking[4]
Creep resistance / sustained load1–5Moderate — no creep test found; Tg of 115 °C (ABS Pro) and 126 °C (ABS Max) keeps room-temperature service far below softening[1][2]Moderate — the long-chain polyamides hold load better than PLA but below PC[4]
Fatigue / repeated-flex resistance1–5Moderate — no S-N curve found; 6.7–7.3 % elongation and 10.5–14.5 kJ/m² notched Charpy, below unfilled Bambu Lab ABS[1][2][24]Excellent — living hinges viable. Stratasys sells FDM Nylon 12 specifically for repetitive-flex parts such as snap-fit clips and press-fit inserts on the strength of its fatigue properties[4][6]
Elasticity / flexibility1–5Rigid[1]Semi-flexible[13]
Z strength as % of XY%63 (ABS Pro) and 71 (ABS Max), printed[1][2]85 (Stratasys FDM Nylon 12, ZX against XZ tensile yield, ASTM D638) — one of the least anisotropic unfilled filaments measured[6]

Environment & Chemical
UV resistance1–5Months outdoors before embrittlement[19]Months outdoors before embrittlement[4]
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[3]Withstands oils, fuels and alkalis[4]
Water / humidity resistance in service1–5Not documentedGood — minor absorption; the least moisture-sensitive of the common nylons[13]
Food contactNot food safe — Polymaker cites potential chemical leaching[19]Not food-contact certified as filament[4]
Biodegradability / compostabilityNot biodegradable[19]Not biodegradable[4]
RecyclabilityMechanically recyclable but not accepted in household plastic collection[19]Mechanically recyclable but not accepted in household plastic collection[4]
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[26][15]Moderate — measurable VOCs and UFPs, ventilation advised[26]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[26]Up to 180 caprolactam, the dominant VOC from nylon; total VOC reached nearly 200 µg/min, the highest of the nine filaments tested[26]
Ultrafine-particle emission rateparticles/min2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[26]≈2 × 10⁸ median — low for ultrafine particles despite the highest VOC mass of any filament tested[26]
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[26][15]Caprolactam, at up to 180 µg/min from nylon filament — the largest single-VOC emission rate measured in the study[26]
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[26][15]Ventilated room or enclosure recommended[26]
Post-Processing
Sanding & machiningSands well and takes filler before painting[19]Sands poorly — gums rather than powders[16]
Painting & finishingPaints readily after light abrasion[19]Not documented
Gluing & solvent weldingNot documentedCyanoacrylate; no common solvent welds polyamide[16]
Vapour / chemical smoothingAcetone vapour smoothing works[3]No practical vapour smoothing[16]
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[27][15]Polymaker sells a break-away PolySupport matched to PA12[16]
Dimensional accuracy & detailNot documentedHolds dimensions better than PA6 after conditioning — Polymaker singles its PA12 grade out on exactly this point[13]
Solvents & Solubility
Soluble inAcetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[28][3]Dissolved at 23 °C by formic acid, phenol, m-cresol, 96 % sulphuric acid or hexafluoroisopropanol — all laboratory reagents.[29][28]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[28][30]Not resistant to 10 % formic acid, phenol, chloroform or dichloromethane (Ensinger); zinc chloride stress-cracks nylon.[28][29]
Solvent welding & smoothing agentAcetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[31]None — nylon's only solvents are formic acid, phenol and HFIP, all of which degrade the part they wet.[29]
