| Identity & Market | ||
| Base polymer / chemistry | Acrylonitrile butadiene styrene — a styrenic terpolymer with a butadiene rubber phase[1][2] | Polyamide 12 — the longest-chain common nylon, with the fewest amide groups per unit mass and so the least moisture uptake[3][4] |
| Densityg/cm³ | 1.04 (Polymaker PolyLite ABS and ABS Pro) to 1.06 (ABS Max), ISO 1183; Bambu Lab 1.05[5][1][6][7] | 1.01 specific gravity (Stratasys FDM Nylon 12, ASTM D792)[8] |
| Typical priceUSD/kg | 1 kg spools cluster near 20[9][10][11][12][13] | 1 kg-equivalent spools span 36–171; the middle of the market is about 64[14][15] |
| Price range across brandsUSD/kg | 12–45 across brands; IEMAI 12, SUNLU 12 at a 3 kg minimum, ELEGOO 15 in a 5 kg pack, Polymaker 19, YXPOLYER 20, Bambu Lab 20, Push Plastic 25, 3DXTech 45[9][10][16][17][11][12][13][18] | 36–171 across brands; IEMAI 3D 36, Fiberlogy 64 at 3DJake, 3DXTech AmideX Nylon 12 171[14][16][15] |

| Typical applications | Enclosures, automotive interior parts and tooling that must hold shape above PLA's 55 °C ceiling[1][19] | Dimensionally stable functional parts, ducting and living hinges where PA6 would move too much with humidity[3][20] |
| Printing Parameters | ||
| Nozzle temperature°C | 240–270 (Bambu Lab); 245–265 (Polymaker PolyLite)[5][1] | 260–290 (Extrudr DURAPRO PA12)[21] |
| Bed temperature°C | 80–100 (Bambu Lab); 90–100 (Polymaker)[5][1] | 110 (Extrudr DURAPRO PA12)[21] |
| Enclosure / chamber requirement1–5 | Enclosure recommended — Polymaker calls a chamber needed at ambient temperature, Bambu Lab requires an enclosed printer and rules out its P1P and A-series machines[1][22] | Enclosure required (passive)[3] |
| Recommended chamber temperature°C | 45–60 (Bambu Lab)[5] | Not documented |
| Part cooling fan | 0–80 % (Bambu Lab); off (Polymaker PolyLite)[5][1] | Part cooling fan not required (Simplify3D)[23] |
| Bed surface & adhesion aid | Clean the plate and apply glue — Bambu Lab lists glue as the way to improve adhesion and prevent warping[22] | PEI sheet with a glue stick, or a dedicated adhesive such as Magigoo[23][3] |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | 10–16 (PrusaSlicer guidance for ABS/ASA)[24] | 12 at Extrudr's 150 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[21][24] |
| Warping tendency1–5 | High — enclosure needed for reliable large parts; Bambu Lab attributes surface cracking to cooling stress exceeding interlayer adhesion[22] | Not documented |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[22] | Needs a specific surface plus adhesive[23][3] |
| Stringing / oozing tendency1–5 | Slight[1] | Moderate — retraction tuning needed[3] |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile[22][1] | Advanced — enclosure, hardware upgrades, tuning[3] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely[22] | Brass fine indefinitely for unfilled grades[3] |
| Abrasiveness1–5 | Non-abrasive[22] | Non-abrasive when unfilled[3] |
| Nozzle clog risk1–5 | Low — no special hot-end required and clogging is not among the listed drawbacks; Prusa lists no drybox and no hardened nozzle[25][26] | High — jams from moisture, heat creep or particles[20][27] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[25] | Moderate — good heatbreak cooling needed[23] |
| Hotend requirement | No special hot-end required[25] | May require an all-metal hot end (Simplify3D)[23] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Moderate — 0.65 % saturated at 25 °C / 55 % RH (Bambu Lab); Polymaker measures 0.51 % maximum uptake for ABS Pro[5][6] | 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[4][20] |
| Equilibrium moisture content at ~50 % RH% | 0.65 saturated at 25 °C / 55 % RH (Bambu Lab); 0.51 maximum (Polymaker ABS Pro)[5][6] | Not documented |
| Drying temperature & time | 80 °C for 8 h (Bambu Lab); 70 °C for 6 h (Polymaker)[5][1] | 60–80 °C for 8–12 h (Extrudr DURAPRO PA12); 100 °C for 8 h (Polymaker CoPA)[21][28] |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing, rough surface and weak layers[27] | Popping and cracking during extrusion, then hard-to-diagnose defects[20] |
| Effect of moisture on strength | Polymaker 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[27] | 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[20][28] |
| Storage requirement | Sealed with desiccant; Polymaker rates ABS moderate-sensitivity and advises periodic drying in humid climates[27] | Sealed below 20 % RH with desiccant[27] |
| Hydrolysis at melt temperature | Not documented | Polymaker 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[28][29] |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 33 ± 3 (Bambu Lab) to 35 (Polymaker ABS Pro and Max) printed XY, ISO 527; 3DXTech quotes 42 at break[5][6][7][30] | 49.3 at yield and 33.4 at break printed XZ (Stratasys FDM Nylon 12, ASTM D638)[8] |
| Young's modulusMPa | 2200 ± 190 (Bambu Lab) to 2330 (Polymaker ABS Pro) printed XY, ISO 527; 3DXTech quotes 1950[5][6][30] | 1510 printed XZ and 1250 ZX (Stratasys FDM Nylon 12, ASTM D638)[8] |
| Elongation at break% | 6.7 (ABS Max) to 10.5 (Bambu Lab) at break, printed XY, ISO 527[5][6][7] | 30 at break printed XZ against 6.5 in ZX (Stratasys FDM Nylon 12, ASTM D638)[8] |
| Flexural strengthMPa | 60 (ABS Pro) to 63 (ABS Max) printed XY, ISO 178; Bambu Lab 62 ± 4; 3DXTech quotes 76[5][6][7][30] | Not documented |
| Flexural modulusMPa | 1880 ± 110 (Bambu Lab) to 2500 (ABS Max) printed XY, ISO 178[5][7] | Not documented |
| Charpy impact, notchedkJ/m² | 10.5 (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] | 11 at +23 °C and 6.0 at -30 °C (Extrudr DuraPro PA12, ISO 179/1eA); unnotched does not break[21] |
| Other impact data | Charpy unnotched 39.3 ± 3.6 printed XY (Bambu Lab, ISO 179); notched 21.5 ± 2.2[5] | Izod notched 138 J/m printed XZ against 71.0 J/m in ZX (Stratasys FDM Nylon 12, ASTM D256)[8] |
| Layer adhesion / Z tensileMPa | 21.9 (ABS Pro) to 29.7 (PolyLite) printed Z, ISO 527; Bambu Lab 28 ± 2[5][1][6] | 41.8 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[8] |
| Brittleness1–5 | Tough — absorbs impact, yields before breaking[5][1] | Tough — absorbs impact, yields before breaking[3] |
| Creep resistance / sustained load1–5 | Moderate — no printed-ABS creep test found; Tg of 101–126 °C keeps room-temperature service far below softening, unlike PLA[1][6][7] | Moderate — the long-chain polyamides hold load better than PLA but below PC[3] |
| Fatigue / repeated-flex resistance1–5 | Moderate — 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][31] | 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[3][8] |
| Elasticity / flexibility1–5 | Rigid[5] | Semi-flexible[20] |
| Z strength as % of XY% | 85 (Bambu Lab, printed Z against XY tensile); 63 for Polymaker ABS Pro[5][6] | 85 (Stratasys FDM Nylon 12, ZX against XZ tensile yield, ASTM D638) — one of the least anisotropic unfilled filaments measured[8] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | 87 (Bambu Lab) to 118 (Polymaker ABS Max), ISO 75 at 0.45 MPa; PolyLite ABS 100[5][1][7] | 94.7 printed XY and 91.9 in XZ/ZX (Stratasys FDM Nylon 12, ASTM D648 at 66 psi)[8] |
| HDT at 1.8 MPa°C | 84 (Bambu Lab) to 113 (Polymaker ABS Max), ISO 75 at 1.8 MPa; PolyLite ABS 98[5][1][7] | 84.3 printed XY and 75.3 in XZ/ZX (Stratasys FDM Nylon 12, ASTM D648 at 264 psi)[8] |
| Glass transition (Tg)°C | 101 (PolyLite) to 126 (ABS Max), DSC; 105 quoted by 3DXTech[1][7][30] | 34.0 (Stratasys FDM Nylon 12, ASTM D7426 inflection point)[8] |
| Melting point / Vicat°C | Amorphous — no melting point; Vicat 104 (PolyLite) to 127 (ABS Max), ISO 306[1][7] | Vicat A 142 (Extrudr DURAPRO PA12, ISO 306)[21] |
| Continuous service temperature°C | 101 measured on a loaded glass-filled ABS bar (My Tech Fun); unfilled ABS is bounded by its 84–98 °C heat deflection[32][5][1] | Bounded by a Vicat softening point of 142 °C (Extrudr DURAPRO PA12); no loaded-bar service figure is published[21] |
| Annealing response | Decomposition above 380 °C (PolyLite ABS, TGA)[1] | Not documented |
| Thermal expansion (CTE)µm/m·K | 86 ± 3 at 0° and 89 ± 3 at 90° raster (printed, fibre Bragg grating, 25–50 °C); 82 for a neat large-format bead at 30 °C[33][34] | 84-103 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)[21][8] |
| Flammability / UL 94 | Flammable; no UL 94 rating published for standard ABS, though V-0 grades exist[35][5] | Flammable; no UL 94 rating published for the unfilled grades surveyed[21] |
| Environment & Chemical | ||
| UV resistance1–5 | Months outdoors before embrittlement[19] | Months outdoors before embrittlement[3] |
| Chemical resistance | Good against weak acids, weak alkalis, oils and grease; poor against strong acids; dissolved by acetone[1] | Withstands oils, fuels and alkalis[3] |
| Water / humidity resistance in service1–5 | Good — minor absorption[5] | Good — minor absorption; the least moisture-sensitive of the common nylons[20] |
| Food contact | Not food safe — Polymaker cites potential chemical leaching[19] | Not food-contact certified as filament[3] |
| Biodegradability / compostability | Not biodegradable[19] | Not biodegradable[3] |
| Recyclability | Mechanically recyclable as resin code 9, but not accepted in household plastic collection[19] | Mechanically recyclable but not accepted in household plastic collection[3] |
| Electrical & ESD properties | Surface resistance above 10¹³ ohm/sq — insulating (3DXTech, ASTM D257)[30] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[36][22] | Moderate — measurable VOCs and UFPs, ventilation advised[36] |
| VOC emission rateµg/min | 12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[36] | Up to 180 caprolactam, the dominant VOC from nylon; total VOC reached nearly 200 µg/min, the highest of the nine filaments tested[36] |
| Ultrafine-particle emission rateparticles/min | 2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[36] | ≈2 × 10⁸ median — low for ultrafine particles despite the highest VOC mass of any filament tested[36] |
| Hazardous species emitted | Styrene 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[36][22] | Caprolactam, at up to 180 µg/min from nylon filament — the largest single-VOC emission rate measured in the study[36] |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[36][22] | Ventilated room or enclosure recommended[36] |
| Post-Processing | ||
| Sanding & machining | Sands well and takes filler; the usual preparation before painting[19] | Sands poorly — gums rather than powders[23] |
| Gluing & solvent welding | Solvent-welds with acetone[1] | Cyanoacrylate; no common solvent welds polyamide[23] |
| Vapour / chemical smoothing | Acetone vapour smoothing works — ABS dissolves in acetone[1] | No practical vapour smoothing[23] |
| Support material pairing | HIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[37][22] | Polymaker sells a break-away PolySupport matched to PA12[23] |
| Dimensional accuracy & detail | Warping and cooling-stress cracking are the accuracy limits, not shrinkage of the melt[22] | Holds dimensions better than PA6 after conditioning — Polymaker singles its PA12 grade out on exactly this point[20] |
| Solvents & Solubility | ||
| Soluble in | Acetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[38][1] | Dissolved at 23 °C by formic acid, phenol, m-cresol, 96 % sulphuric acid or hexafluoroisopropanol — all laboratory reagents.[39][38] |
| Softened or crazed by | Petrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[38][40] | Not resistant to 10 % formic acid, phenol, chloroform or dichloromethane (Ensinger); zinc chloride stress-cracks nylon.[38][39] |
| Solvent welding & smoothing agent | Acetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[41] | None — nylon's only solvents are formic acid, phenol and HFIP, all of which degrade the part they wet.[39] |
