Base polymer / chemistryAcrylonitrile butadiene styrene — a styrenic terpolymer with a butadiene rubber phase[1][2]PLA filled with chopped glass fibre — 12 wt% (Polymaker HT-PLA-GF), 15–20 wt% (eSUN PLA-GF). Bambu Lab PLA Galaxy uses glass microspheres, not fibre, and is not equivalent[3][4][5]
Densityg/cm³1.04 (Polymaker PolyLite ABS and ABS Pro) to 1.06 (ABS Max), ISO 1183; Bambu Lab 1.05[6][1][7][8]1.31 (eSUN) to 1.337 (Polymaker), ISO 1183 / GB/T 1033[3][4]
Typical priceUSD/kg1 kg spools cluster near 20[9][10][11][12][13]1 kg spools cluster near 30[14][15]
Price range across brandsUSD/kg12–45 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]30–60 across brands; Polymaker 30, Proto-pasta 60[14][15]
Market availability1–5Ubiquitous, every brand and retailer[9][10][16][17]Niche, a handful of specialist brands[14][15][4]
Spool sizes & diameters1.75 and 2.85 mm; 1, 5 and 10 kg spools[16][17]1.75 mm; 0.5 and 1 kg spools[15][10]
Typical applicationsEnclosures, automotive interior parts and tooling that must hold shape above PLA's 55 °C ceiling[1][19]Stiff brackets and fixtures; the Polymaker grade is aimed at parts annealed for heat resistance[3]
Printing Parameters
Nozzle temperature°C240–270 (Bambu Lab); 245–265 (Polymaker PolyLite)[6][1]210–230 (Polymaker HT-PLA-GF)[3]
Bed temperature°C80–100 (Bambu Lab); 90–100 (Polymaker)[6][1]25–60 (Polymaker HT-PLA-GF)[3]
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][20]Open frame is fine[3]
Recommended chamber temperature°C45–60 (Bambu Lab)[6]Not documented
Part cooling fan0–80 % (Bambu Lab); off (Polymaker PolyLite)[6][1]Fan on — eSUN specifies 100 %[4]
Bed surface & adhesion aidClean the plate and apply glue — Bambu Lab lists glue as the way to improve adhesion and prevent warping[20]Not documented
Maximum volumetric flow (mm³/s; see test conditions)mm³/s10–16 (PrusaSlicer guidance for ABS/ASA)[21]28 at Polymaker's stated 350 mm/s on a 0.4 mm nozzle at 0.2 mm layer; eSUN prints its specimens at 60 mm/s[3][4][21]
Warping tendency1–5High — enclosure needed for reliable large parts; Bambu Lab attributes surface cracking to cooling stress exceeding interlayer adhesion[20]Not documented
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[20]Not documented
Stringing / oozing tendency1–5Slight[1]Not documented
Shrinkage%Not documented0.05 in X-Y and Z, 0.10 diagonal (Polymaker HT-PLA-GF)[3]
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile[20][1]Intermediate — dry filament and a tuned profile; hardened nozzle mandatory[3]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[20]Hardened steel required[3]
Abrasiveness1–5Non-abrasive[20]Highly abrasive — standard GF composite[3]
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]Moderate — needs dry filament and a clean nozzle; Prusa lists higher risk of nozzle clogging for glass-filled composites[24]
Heat-creep / jam sensitivity1–5Slightly sensitive[22]Not documented
Hotend requirementNo special hot-end required[22]Hardened steel or ruby nozzle; Polymaker's own slicer preset sets a minimum nozzle hardness of 40 HRC[3]
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[6][7]Moderate — the PLA matrix takes up 0.40–0.51 % saturated; no glass-filled grade publishes its own figure[25][26]
Equilibrium moisture content at ~50 % RH%0.65 saturated at 25 °C / 55 % RH (Bambu Lab); 0.51 maximum (Polymaker ABS Pro)[6][7]Not documented
Drying temperature & time80 °C for 8 h (Bambu Lab); 70 °C for 6 h (Polymaker)[6][1]60 °C for 6 h (Polymaker HT-PLA-GF)[3]
Symptoms when wetBubbling and popping at the nozzle, stringing, rough surface and weak layers[27]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[27]Polymaker rates PLA low-sensitivity and publishes no dry-versus-conditioned figures for this grade; absorbed water flashes to steam and shows as bubbling and poor layer adhesion[27]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity and advises periodic drying in humid climates[27]Not documented

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[33][6][1]Not documented
Annealing responseDecomposition above 380 °C (PolyLite ABS, TGA)[1]Annealing lifts HDT at 0.45 MPa from 75.5 to 114.7 °C and modulus from 3794 to 4207 MPa[3]

Flammability / UL 94Flammable; no UL 94 rating published for standard ABS, though V-0 grades exist[36][6]Not documented
Environment & Chemical
UV resistance1–5Months outdoors before embrittlement[19]Degrades within weeks outdoors[37]
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; poor against strong acids; dissolved by acetone[1]Not documented
Water / humidity resistance in service1–5Good — minor absorption[6]Not documented
Food contactNot food safe — Polymaker cites potential chemical leaching[19]Not documented
Biodegradability / compostabilityNot biodegradable[19]Not documented
RecyclabilityMechanically recyclable as resin code 9, but not accepted in household plastic collection[19]Not documented
Electrical & ESD propertiesSurface resistance above 10¹³ ohm/sq — insulating (3DXTech, ASTM D257)[28]Not documented
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[38][20]Low hazard — minimal VOC and particle emission[38]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[38]Not documented
Ultrafine-particle emission rateparticles/min2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[38]Not documented
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[38][20]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[38][20]None needed in a normal room[38]
Dust & fibre handling hazardNot documentedGlass fibre is bound in the matrix; avoid inhaling sanding dust[39]
Post-Processing
Sanding & machiningSands well and takes filler; the usual preparation before painting[19]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[40][20]Not documented
Dimensional accuracy & detailWarping and cooling-stress cracking are the accuracy limits, not shrinkage of the melt[20]Near-zero shrinkage — 0.05 % in X-Y and Z (Polymaker)[3]
Solvents & Solubility
Soluble inAcetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[41][1]Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[42]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[41][43]Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[42][44]
Solvent welding & smoothing agentAcetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[44]Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[45][44]
