Printing Parameters
Nozzle temperature°CNot documented260–290 (Extrudr DURAPRO PA12)[11]
Bed temperature°CNot documented110 (Extrudr DURAPRO PA12)[11]
Enclosure / chamber requirement1–5Enclosure recommended[12]Enclosure required (passive)[2]
Part cooling fanNot documentedPart cooling fan not required (Simplify3D)[13]
Bed surface & adhesion aidClean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[12][14]PEI sheet with a glue stick, or a dedicated adhesive such as Magigoo[13][2]
Maximum volumetric flow (mm³/s; see test conditions)mm³/sNot documented12 at Extrudr's 150 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[11][15]
Warping tendency1–5High — enclosure needed for reliable large parts[12]Not documented
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[12]Needs a specific surface plus adhesive[13][2]
Stringing / oozing tendency1–5Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[16]Moderate — retraction tuning needed[2]
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile[12]Advanced — enclosure, hardware upgrades, tuning[2]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[1]Brass fine indefinitely for unfilled grades[2]
Abrasiveness1–5Moderately abrasive — conductive carbon filler[1]Non-abrasive when unfilled[2]
Nozzle clog risk1–5Low — 3DXTech lists no special nozzle concerns and no minimum layer height for its ESD-ABS, only an 80 °C pre-dry[17]High — jams from moisture, heat creep or particles[10][18]
Heat-creep / jam sensitivity1–5Slightly sensitive[14]Moderate — good heatbreak cooling needed[13]
Hotend requirementNo special hot-end required[14]May require an all-metal hot end (Simplify3D)[13]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate — the ABS matrix takes up 0.51–0.65 % saturated at 25 °C / 55 % RH and 3DXTech specifies a 80 °C, 4 h pre-dry[19][20][17]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[3][10]
Drying temperature & timeNot documented60–80 °C for 8–12 h (Extrudr DURAPRO PA12); 100 °C for 8 h (Polymaker CoPA)[11][21]
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[18]Popping and cracking during extrusion, then hard-to-diagnose defects[10]
Effect of moisture on strengthPolymaker rates ABS moderate-sensitivity and publishes no dry-versus-conditioned figures; absorbed water flashes to steam in the hotend and shows as bubbling and poor layer adhesion[18]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[10][21]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity[18]Sealed below 20 % RH with desiccant[18]
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[21][22]
Mechanical Properties
Tensile strength (XY)MPa58 at break (printed XY, ISO 527) — the conductive filler raises strength above the unfilled grade's 42[1][23]49.3 at yield and 33.4 at break printed XZ (Stratasys FDM Nylon 12, ASTM D638)[4]
Young's modulusMPa2130 (printed XY, ISO 527)[1]1510 printed XZ and 1250 ZX (Stratasys FDM Nylon 12, ASTM D638)[4]
Elongation at break%4 at break (printed XY, ISO 527)[1]30 at break printed XZ against 6.5 in ZX (Stratasys FDM Nylon 12, ASTM D638)[4]
Flexural strengthMPa80 (printed XY, ISO 178)[1]Not documented
Flexural modulusMPa2275 (printed XY, ISO 178)[1]Not documented
Charpy impact, notchedkJ/m²Not documented11 at +23 °C and 6.0 at -30 °C (Extrudr DuraPro PA12, ISO 179/1eA); unnotched does not break[11]
Other impact dataNot documentedIzod notched 138 J/m printed XZ against 71.0 J/m in ZX (Stratasys FDM Nylon 12, ASTM D256)[4]
Layer adhesion / Z tensileMPaNot documented41.8 at yield and 41.2 at break printed ZX (Stratasys FDM Nylon 12, ASTM D638) — higher than the XZ break figure, because XZ specimens draw and neck first[4]
Brittleness1–5Moderate[1]Tough — absorbs impact, yields before breaking[2]
Creep resistance / sustained load1–5Moderate — no creep test found; Tg of 105 °C keeps room-temperature service far below softening[1]Moderate — the long-chain polyamides hold load better than PLA but below PC[2]
Fatigue / repeated-flex resistance1–5Below average — no S-N curve found; elongation at break 4 %, well below unfilled ABS[1][23]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[2][4]
Elasticity / flexibility1–5Rigid[1]Semi-flexible[10]
Z strength as % of XY%Not documented85 (Stratasys FDM Nylon 12, ZX against XZ tensile yield, ASTM D638) — one of the least anisotropic unfilled filaments measured[4]
Thermal Properties
HDT at 0.45 MPa°CNot documented94.7 printed XY and 91.9 in XZ/ZX (Stratasys FDM Nylon 12, ASTM D648 at 66 psi)[4]
HDT at 1.8 MPa°CNot documented84.3 printed XY and 75.3 in XZ/ZX (Stratasys FDM Nylon 12, ASTM D648 at 264 psi)[4]
Glass transition (Tg)°C105 (DSC)[1]34.0 (Stratasys FDM Nylon 12, ASTM D7426 inflection point)[4]
Melting point / Vicat°CNot documentedVicat A 142 (Extrudr DURAPRO PA12, ISO 306)[11]
Continuous service temperature°CNot documentedBounded by a Vicat softening point of 142 °C (Extrudr DURAPRO PA12); no loaded-bar service figure is published[11]
Thermal expansion (CTE)µm/m·KNot documented84-103 printed (Stratasys FDM Nylon 12, ASTM E831: 84.4 in XY and 85.6 in XZ/ZX over -50 to 10 °C, 89.1 over 10-45 °C, 98.2 over 45-70 °C); Extrudr quotes 100 for DURAPRO PA12 (ISO 11359-2)[11][4]
Flammability / UL 94Not documentedFlammable; no UL 94 rating published for the unfilled grades surveyed[11]
Environment & Chemical
UV resistance1–5Not documentedMonths outdoors before embrittlement[2]
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[24]Withstands oils, fuels and alkalis[2]
Water / humidity resistance in service1–5Not documentedGood — minor absorption; the least moisture-sensitive of the common nylons[10]
Food contactNot food safe — Polymaker cites potential chemical leaching[16]Not food-contact certified as filament[2]
Biodegradability / compostabilityNot biodegradable[16]Not biodegradable[2]
RecyclabilityMechanically recyclable but not accepted in household plastic collection[16]Mechanically recyclable but not accepted in household plastic collection[2]
Electrical & ESD propertiesSurface resistance 10⁷–10⁹ ohm/sq, the static-dissipative band (ASTM D257), against above 10¹³ for unfilled ABS[1][23]Not documented
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[25][12]Moderate — measurable VOCs and UFPs, ventilation advised[25]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[25]Up to 180 caprolactam, the dominant VOC from nylon; total VOC reached nearly 200 µg/min, the highest of the nine filaments tested[25]
Ultrafine-particle emission rateparticles/min2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[25]≈2 × 10⁸ median — low for ultrafine particles despite the highest VOC mass of any filament tested[25]
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[25][12]Caprolactam, at up to 180 µg/min from nylon filament — the largest single-VOC emission rate measured in the study[25]
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[25][12]Ventilated room or enclosure recommended[25]
Dust & fibre handling hazardConductive carbon filler is bound in the matrix; avoid inhaling sanding dust[1]Not documented
Post-Processing
Sanding & machiningSands well and takes filler before painting[16]Sands poorly — gums rather than powders[13]
Painting & finishingPaints readily after light abrasion[16]Not documented
Gluing & solvent weldingNot documentedCyanoacrylate; no common solvent welds polyamide[13]
Vapour / chemical smoothingNot documentedNo practical vapour smoothing[13]
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[26][12]Polymaker sells a break-away PolySupport matched to PA12[13]
Dimensional accuracy & detailNot documentedHolds dimensions better than PA6 after conditioning — Polymaker singles its PA12 grade out on exactly this point[10]
Solvents & Solubility
Soluble inAcetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[27][24]Dissolved at 23 °C by formic acid, phenol, m-cresol, 96 % sulphuric acid or hexafluoroisopropanol — all laboratory reagents.[28][27]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[27][29]Not resistant to 10 % formic acid, phenol, chloroform or dichloromethane (Ensinger); zinc chloride stress-cracks nylon.[27][28]
Solvent welding & smoothing agentAcetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[30]None — nylon's only solvents are formic acid, phenol and HFIP, all of which degrade the part they wet.[28]
