Identity & Market
Base polymer / chemistryAcrylonitrile butadiene styrene — a styrenic terpolymer with a butadiene rubber phase[1][2]Polyamide 66, condensed from hexamethylenediamine and adipic acid; melts around 40 °C above PA6[3]
Densityg/cm³1.04 (Polymaker PolyLite ABS and ABS Pro) to 1.06 (ABS Max), ISO 1183; Bambu Lab 1.05[4][1][5][6]1.14 (extruded unfilled PA66 stock)[7]
Typical priceUSD/kg1 kg spools cluster near 20[8][9][10][11][12]Not documented

Market availability1–5Ubiquitous, every brand and retailer[8][9][13][14]Special order, 1–2 makers worldwide — no unfilled PA66 filament appeared in any catalogue searched, and the 3DXTech nylon range offers PA6, PA12 and a 6/66 copolymer but no straight PA66[13][9]
Spool sizes & diameters1.75 and 2.85 mm; 1, 5 and 10 kg spools[13][14]Not documented
Typical applicationsEnclosures, automotive interior parts and tooling that must hold shape above PLA's 55 °C ceiling[1][16]Not documented
Printing Parameters
Nozzle temperature°C240–270 (Bambu Lab); 245–265 (Polymaker PolyLite)[4][1]Not documented
Bed temperature°C80–100 (Bambu Lab); 90–100 (Polymaker)[4][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)[3]
Recommended chamber temperature°C45–60 (Bambu Lab)[4]Not documented
Part cooling fan0–80 % (Bambu Lab); off (Polymaker PolyLite)[4][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]Not documented
Maximum volumetric flow (mm³/s; see test conditions)mm³/s10–16 (PrusaSlicer guidance for ABS/ASA)[18]Not documented
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]Not documented
Stringing / oozing tendency1–5Slight[1]Not documented
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile[17][1]Advanced — enclosure, hardware upgrades, tuning[3]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[17]Not documented
Abrasiveness1–5Non-abrasive[17]Not documented
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[19][20]Very high — frequent jams without careful setup[21][22]
Heat-creep / jam sensitivity1–5Slightly sensitive[19]Not documented
Hotend requirementNo special hot-end required[19]Not documented
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[4][5]Very high (>2 %)[22]
Equilibrium moisture content at ~50 % RH%0.65 saturated at 25 °C / 55 % RH (Bambu Lab); 0.51 maximum (Polymaker ABS Pro)[4][5]8.5 at saturation on extruded PA66 stock (ASTM D570) — the highest uptake of any polymer in this dataset[7]
Drying temperature & time80 °C for 8 h (Bambu Lab); 70 °C for 6 h (Polymaker)[4][1]Not documented
Symptoms when wetBubbling and popping at the nozzle, stringing, rough surface and weak layers[22]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[22]Measured dry against wet on printed specimens at 6.16 % moisture (Polymaker CoPA): tensile 78.0 → 34.3 MPa, Young's modulus 2703 → 724 MPa, flexural strength 109.8 → 22.6 MPa, while notched Charpy rises 6.9 → 27.7 kJ/m² and elongation 12.7 → 13.2 %[23][21]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity and advises periodic drying in humid climates[22]Not documented

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][5][6]Not documented
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[4][25]Excellent — living hinges viable[3]
Elasticity / flexibility1–5Rigid[4]Semi-flexible[21]
Z strength as % of XY%85 (Bambu Lab, printed Z against XY tensile); 63 for Polymaker ABS Pro[4][5]Not documented

Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[30][17]Moderate — measurable VOCs and UFPs, ventilation advised[30]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[30]Up to 180 caprolactam, the dominant VOC from nylon; total VOC reached nearly 200 µg/min, the highest of the nine filaments tested[30]
Ultrafine-particle emission rateparticles/min2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[30]≈2 × 10⁸ median — low for ultrafine particles despite the highest VOC mass of any filament tested[30]
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[30][17]Caprolactam, at up to 180 µg/min from nylon filament — the largest single-VOC emission rate measured in the study[30]
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[30][17]Ventilated room or enclosure recommended[30]
Post-Processing
Sanding & machiningSands well and takes filler; the usual preparation before painting[16]Not documented
Gluing & solvent weldingSolvent-welds with acetone[1]Not documented
Vapour / chemical smoothingAcetone vapour smoothing works — ABS dissolves in acetone[1]Not documented
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[31][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.[32][1]Dissolved at 23 °C by formic acid above ~80 %, phenol, m-cresol, 96 % sulphuric acid or hexafluoroisopropanol — laboratory reagents.[33]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[32][34]Zinc chloride solutions stress-crack it — 10 % marginal, 37 % not resistant; alcoholic calcium chloride dissolves it.[33]
Solvent welding & smoothing agentAcetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[35]None — nylon's only solvents are formic acid, phenol and HFIP, all of which degrade the part they wet.[33]
