Identity & Market
Base polymer / chemistryAcrylonitrile butadiene styrene — a styrenic terpolymer with a butadiene rubber phase[1][2]Glass-fibre reinforced polyester. Polymaker's Fiberon PET-GF15 uses a PET rather than a PETG matrix and carries 15 wt% glass fibre[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]1.43 (Fiberon PET-GF15, ISO 1183)[3]
Typical priceUSD/kg1 kg spools cluster near 20[7][8][9][10][11]1 kg spools cluster near 25[12][8]
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[7][8][13][12][9][10][11][14]19–30 across brands; ELEGOO 19, Polymaker Fiberon 30[12][8]
Market availability1–5Ubiquitous, every brand and retailer[7][8][13][12]Niche, a handful of specialist brands[12][8]
Spool sizes & diameters1.75 and 2.85 mm; 1, 5 and 10 kg spools[13][12]1.75 mm; 0.5 and 1 kg spools[8]
Typical applicationsEnclosures, automotive interior parts and tooling that must hold shape above PLA's 55 °C ceiling[1][15]Stiff, dimensionally stable fixtures; the Fiberon grade is designed to be annealed for heat resistance[3]
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][16]Not documented
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[16]Textured PEI, satin or powder-coated sheets; on smooth PEI a glue stick acts as a release agent[17][18]
Maximum volumetric flow (mm³/s; see test conditions)mm³/s10–16 (PrusaSlicer guidance for ABS/ASA)[19]Not documented
Warping tendency1–5High — enclosure needed for reliable large parts; Bambu Lab attributes surface cracking to cooling stress exceeding interlayer adhesion[16]Not documented
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[16]Needs the right surface or a thin adhesive — the problem is releasing the part, not sticking it[17][18]
Stringing / oozing tendency1–5Slight[1]Moderate — retraction tuning needed; Polymaker names stringing as PETG's common quirk[18]
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile[16][1]Not documented
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[16]Hardened steel required[3]
Abrasiveness1–5Non-abrasive[16]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[20][21]Moderate — needs dry filament and a clean nozzle; Prusa lists higher risk of nozzle clogging for glass-filled composites[22]
Heat-creep / jam sensitivity1–5Slightly sensitive[20]Slightly sensitive[23]
Hotend requirementNo special hot-end required[20]No special hot-end required[23]
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]Moderate (0.3–0.8 %) — the PETG matrix reaches 0.40 % saturated at 25 °C / 55 % RH; no glass-filled grade publishes its own figure[17]
Equilibrium moisture content at ~50 % RH%0.65 saturated at 25 °C / 55 % RH (Bambu Lab); 0.51 maximum (Polymaker ABS Pro)[4][5]Not documented
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[24]Bubbling and popping at the nozzle, stringing and a rough surface[24]
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[24]Polymaker groups PETG with nylon, PVA and TPU as highly hygroscopic; no dry-versus-conditioned strength figures are published for this grade and the loss shows as bubbling and poor layer adhesion[24]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity and advises periodic drying in humid climates[24]Sealed with desiccant; Polymaker groups PETG with the highly hygroscopic materials[24][18]

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]Below average — no GF-grade creep test; the CF grades sagged to 14.8–16.7 mm over 5 days at 1.25 kg against 17.1–20.4 mm unfilled[26][27][28]

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[30][4][1]Not documented
Annealing responseDecomposition above 380 °C (PolyLite ABS, TGA)[1]Annealing lifts HDT at 0.45 MPa from 81.6 to 133.7 °C[3]
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[31][32]20 along the print bead and 63–74 in the build direction at 30 °C (30 wt% GF, large-format printed, TMA)[32]
Flammability / UL 94Flammable; no UL 94 rating published for standard ABS, though V-0 grades exist[33][4]UL 94 HB at 1.5 mm (Fiberon PET-GF15)[3]
Environment & Chemical

RecyclabilityMechanically recyclable as resin code 9, but not accepted in household plastic collection[15]Not accepted in household plastic collection[18]
Electrical & ESD propertiesSurface resistance above 10¹³ ohm/sq — insulating (3DXTech, ASTM D257)[25]Surface resistivity above 10¹² ohm — insulating (Fiberon PET-GF15, ANSI/ESD S11.11)[3]
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[34][16]Moderate — measurable VOCs and UFPs, ventilation advised[34]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[34]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[34]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[34][16]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[34][16]Open a window / occasional ventilation[34]
Dust & fibre handling hazardNot documentedGlass fibre is bound in the matrix; avoid inhaling sanding dust[3]
Post-Processing
Sanding & machiningSands well and takes filler; the usual preparation before painting[15]Sands poorly — the material is tough and gums rather than powders[23]
Gluing & solvent weldingSolvent-welds with acetone[1]Cyanoacrylate; no common solvent welds PETG cleanly[23]
Vapour / chemical smoothingAcetone vapour smoothing works — ABS dissolves in acetone[1]No practical vapour smoothing[23]
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[35][16]Prints its own supports; Polymaker rates PolyDissolve S1 for PETG[23]
Dimensional accuracy & detailWarping and cooling-stress cracking are the accuracy limits, not shrinkage of the melt[16]Not documented
Solvents & Solubility
Soluble inAcetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[36][1]No common workshop solvent; dichloromethane — a carcinogen — dissolves the matrix surface, 1,2-dichloroethane destroys it in a week.[37][38]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[36][39]Acetone (+16 % weight over 1 year at 23 °C), ethyl acetate, toluene and DMF swell and soften it; methanol crazes it.[37]
Solvent welding & smoothing agentAcetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[38]Dichloromethane reaches only the resin, so the fibre is left standing proud of the surface. Controlled carcinogen.[38]
