Bed temperature°C80–100 (Bambu Lab); 90–100 (Polymaker)[5][1]Not documented
Enclosure / chamber requirement1–5Enclosure 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][17]Enclosure required (passive) — Bambu Lab specifies a 45–60 °C chamber[3]
Recommended chamber temperature°C45–60 (Bambu Lab)[5]45–60 (Bambu Lab)[3]
Part cooling fan0–80 % (Bambu Lab); off (Polymaker PolyLite)[5][1]Not documented
Bed surface & adhesion aidClean the plate and apply glue — Bambu Lab lists glue as the way to improve adhesion and prevent warping[17]PEI sheet with a glue stick, or a dedicated adhesive such as Magigoo[18][19]
Maximum volumetric flow (mm³/s; see test conditions)mm³/s10–16 (PrusaSlicer guidance for ABS/ASA)[20]8 at Bambu Lab's 100 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[3][20]
Warping tendency1–5High — enclosure needed for reliable large parts; Bambu Lab attributes surface cracking to cooling stress exceeding interlayer adhesion[17]Not documented
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[17]Needs a specific surface plus adhesive[18]
Stringing / oozing tendency1–5Slight[1]Moderate — retraction tuning needed[19]
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile[17][1]Expert / industrial hardware only[3][21]
Extruder requirementNot documented0.6 mm nozzle recommended by Bambu Lab; 0.4 and 0.8 also supported[3]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[17]Hardened steel required — Polymaker measures brass nozzle life at about 9 h on PA612-CF15 and recommends hardened steel or ruby[4]
Abrasiveness1–5Non-abrasive[17]Highly abrasive — standard CF composite; Polymaker puts brass nozzle life at roughly 9 h on PA612-CF15[4]
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[22][23]High — jams from moisture, heat creep or particles[21]
Heat-creep / jam sensitivity1–5Slightly sensitive[22]Moderate — good heatbreak cooling needed[18]
Hotend requirementNo special hot-end required[22]May require an all-metal hot end (Simplify3D)[18]
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]High (0.8–2 %) — 0.88 % saturated at 25 °C / 55 % RH for Bambu Lab PAHT-CF, a third of its PA6-CF; Polymaker's PA612-CF15 reaches 2.2 % equilibrium[3][4][24]
Equilibrium moisture content at ~50 % RH%0.65 saturated at 25 °C / 55 % RH (Bambu Lab); 0.51 maximum (Polymaker ABS Pro)[5][6]0.88 saturated at 25 °C / 55 % RH (Bambu Lab PAHT-CF); 2.2 equilibrium (Polymaker PA612-CF15)[3][4]
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)[3]
Symptoms when wetBubbling and popping at the nozzle, stringing, rough surface and weak layers[21]Not documented
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[21]Polymaker publishes dry and wet printed blocks for PA612-CF15 itself: at 2.57 % moisture tensile falls only 91.9 → 83.1 MPa and modulus 5137 → 3991 MPa — the PA612 backbone absorbs far less than PA6[4][25]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity and advises periodic drying in humid climates[21]Sealed below 20 % RH with desiccant[21]
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[26][27]
Mechanical Properties
Tensile strength (XY)MPa33 ± 3 (Bambu Lab) to 35 (Polymaker ABS Pro and Max) printed XY, ISO 527; 3DXTech quotes 42 at break[5][6][7][28]92 ± 7 (Bambu Lab) and 91.9 ± 2.0 (Polymaker PA612-CF15, dry/annealed) printed XY, ISO 527; the Polymaker grade only falls to 83.1 ± 2.2 conditioned to 2.57 % moisture[3][4]

Flexural strengthMPa60 (ABS Pro) to 63 (ABS Max) printed XY, ISO 178; Bambu Lab 62 ± 4; 3DXTech quotes 76[5][6][7][28]Not documented
Flexural modulusMPa1880 ± 110 (Bambu Lab) to 2500 (ABS Max) printed XY, ISO 178[5][7]4230 ± 210 printed XY, ISO 178 (Bambu Lab)[3]
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]8.1 ± 0.8 printed XY dry and 7.7 ± 0.5 conditioned, ISO 179 notched (Polymaker PA612-CF15)[4]
Other impact dataCharpy unnotched 39.3 ± 3.6 printed XY (Bambu Lab, ISO 179); notched 21.5 ± 2.2[5]Charpy unnotched 57.5 ± 3.4 and notched 22.8 ± 1.8 printed XY (Bambu Lab, ISO 179)[3]
Layer adhesion / Z tensileMPa21.9 (ABS Pro) to 29.7 (PolyLite) printed Z, ISO 527; Bambu Lab 28 ± 2[5][1][6]47 ± 5 (Bambu Lab) and 48.3 ± 3.9 (Polymaker PA612-CF15, dry) printed Z, ISO 527; Polymaker 35.6 ± 3.0 conditioned[3][4]
Brittleness1–5Tough — absorbs impact, yields before breaking[5][1]Moderate[3]
Hardness (scale-specific)Shore A / Shore D / RockwellNot documentedRockwell M88 / R117 on extruded PA66-GF30 stock (ASTM D785); no figure is published for a carbon-fibre long-chain nylon filament[29]
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 rates its PA66-CF30 compound for sustained static and dynamic load with 110 °C continuous service; the long-chain PA612 matrix takes up 0.88 % at saturation, a third of the same maker's PA6-CF, so it holds dimension better[30][4]
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][31]Good. Ensinger states carbon-filled PA66 compounds have improved fatigue strength in tension, flexure and compression[30]
Elasticity / flexibility1–5Rigid[5]Rigid[3]
Z strength as % of XY%85 (Bambu Lab, printed Z against XY tensile); 63 for Polymaker ABS Pro[5][6]51 (Bambu Lab) to 53 (Polymaker PA612-CF15), printed[3][4]

Continuous service temperature°C101 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]Not documented
Annealing responseDecomposition above 380 °C (PolyLite ABS, TGA)[1]Not documented
Thermal expansion (CTE)µm/m·K86 ± 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]Not documented
Flammability / UL 94Flammable; no UL 94 rating published for standard ABS, though V-0 grades exist[35][5]Flammable; no UL 94 rating published for the grades surveyed[26]
Environment & Chemical
UV resistance1–5Months outdoors before embrittlement[16]Months outdoors before embrittlement — unstabilised polyamide yellows under UV[19]
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; poor against strong acids; dissolved by acetone[1]Withstands oils, fuels and alkalis[19]
Water / humidity resistance in service1–5Good — minor absorption[5]Absorbs water, properties shift — less than PA6 but more than PA12[25][3]
Food contactNot food safe — Polymaker cites potential chemical leaching[16]Not food-contact certified as filament[19]
Biodegradability / compostabilityNot biodegradable[16]Not biodegradable[19]
RecyclabilityMechanically recyclable as resin code 9, but not accepted in household plastic collection[16]Not accepted in household plastic collection[19]
Electrical & ESD propertiesSurface resistance above 10¹³ ohm/sq — insulating (3DXTech, ASTM D257)[28]Surface resistivity above 10¹² ohm — insulating (Polymaker PA612-CF15, ANSI/ESD S11.11)[4]
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[36][17]Moderate — measurable VOCs and UFPs, ventilation advised[36]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[36]Up to 180 caprolactam, the dominant VOC from nylon and the largest single-VOC rate in the study[36]
Ultrafine-particle emission rateparticles/min2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[36]≈2 × 10⁸ median for nylon — low for particles despite the highest VOC mass measured[36]
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[36][17]Caprolactam, at up to 180 µg/min from nylon filament[36]
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[36][17]Ventilated room or enclosure recommended[36]
Dust & fibre handling hazardNot documentedFibre is bound in the matrix; sanding dust should not be inhaled[26]
Post-Processing
Sanding & machiningSands well and takes filler; the usual preparation before painting[16]Sands poorly — gums rather than powders[18]
Gluing & solvent weldingSolvent-welds with acetone[1]Cyanoacrylate; no common solvent welds polyamide[18]
Vapour / chemical smoothingAcetone vapour smoothing works — ABS dissolves in acetone[1]No practical vapour smoothing[18]
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[37][17]Not documented
Dimensional accuracy & detailWarping and cooling-stress cracking are the accuracy limits, not shrinkage of the melt[17]Not documented
Solvents & Solubility
Soluble inAcetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[38][1]Formic acid, phenol, m-cresol and hexafluoroisopropanol dissolve the matrix at 23 °C, leaving the fibre; laboratory reagents.[39]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[38][40]Zinc chloride solutions stress-crack the nylon matrix, alcoholic calcium chloride dissolves it, mineral acids attack it.[39]
Solvent welding & smoothing agentAcetone: 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 (formic acid, phenol, HFIP) degrade the part, and the fibre blocks surface flow anyway.[39]
