Bed temperature°C80–100 (Bambu Lab)[2]30–60 (Polymaker); 35–45 (Bambu Lab)[3][19]
Enclosure / chamber requirement1–5Enclosure recommended — Bambu Lab specifies a 45–60 °C chamber[2][20]Open frame is fine[3]
Recommended chamber temperature°C45–60 (Bambu Lab)[2]Not documented
Part cooling fan0–80 % (Bambu Lab)[2]Fan on[3]
Bed surface & adhesion aidClean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[20][21]Not documented
Maximum volumetric flow (mm³/s; see test conditions)mm³/s14 at Bambu Lab's 180 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[2][22]≈24 at 300 mm/s with a 0.4 mm nozzle and 0.2 mm layer; 30 % more flow than regular PLA at the same temperature[3][15][17][22]
Warping tendency1–5Moderate — needs adhesion aid or draught shield; Bambu Lab positions the fibre as reducing warping[2]None[3]
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[20]Sticks to anything[23]
Stringing / oozing tendency1–5Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[24]Not documented
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile; hardened nozzle mandatory[20]Easy — minor profile tuning; needs a printer that can actually reach the flow rate[15][3]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[20]Brass fine indefinitely[25]
Abrasiveness1–5Highly abrasive — standard GF composite[20]Non-abrasive[26][25]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle; 3DXTech specifies a hardened 0.4 mm minimum nozzle and 0.25 mm layers or higher for the glass-filled grade[27][28]Very low[25]
Heat-creep / jam sensitivity1–5Slightly sensitive[21]Moderate — good heatbreak cooling needed; PLA softens below 60 °C[29]
Hotend requirementNo special hot-end required[21]No special hot-end required[23]
Moisture Behaviour

Equilibrium moisture content at ~50 % RH%0.53 saturated at 25 °C / 55 % RH (Bambu Lab)[2]0.40 equilibrium at 23 °C / 70 % RH (Polymaker PolySonic)[3]
Drying temperature & time80 °C for 8 h (Bambu Lab)[2]55 °C for 6 h; 50 °C for 8 h (Bambu Lab)[3][19]
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[30]Bubbling and popping at the nozzle, stringing, rough surface and weak layers[30]
Effect of moisture on strengthPolymaker rates ABS moderate-sensitivity and publishes no dry-versus-conditioned figures; absorbed water flashes to steam in the hotend and shows as bubbling and poor layer adhesion[30]Polymaker rates PLA low-sensitivity — the loss shows as poor layer adhesion and brittle layers rather than a published strength figure[30]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity[30]Sealed with desiccant below 20 % RH; shelf life at ambient is long[19][23]

Other impact dataCharpy unnotched 14.5 ± 1.5 printed XY (Bambu Lab, ISO 179)[2]Printing at 300 mm/s instead of 46.7 mm/s costs 4.6 % tensile strength and 18 % notched Charpy[3]

Creep resistance / sustained load1–5Good — no creep test found; chopped glass fibre lifts modulus to 3160 MPa against 2200 for unfilled Bambu Lab ABS[2][32]Poor — 12 mm bar sagged to 17.7 mm over 6 days at 1.25 kg[31]
Fatigue / repeated-flex resistance1–5Below average — no S-N curve found; notched Charpy falls to 4.2 kJ/m² against 21.5 for unfilled Bambu Lab ABS[2][32]Poor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength (R = 0.2)[34][29]

Flammability / UL 94Not documentedFlammable; no UL 94 rating published by the major brands[19][4]
Environment & Chemical
UV resistance1–5Not documentedDegrades within weeks outdoors[29][36]
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[37]Good against weak acids, oils and grease; poor against strong acids and alkalis[3]
Water / humidity resistance in service1–5Not documentedGood — insoluble in water[19]
Food contactNot food safe — Polymaker cites potential chemical leaching[24]Base resin is food-contact grade, but printed layer grooves harbour bacteria; Prusa advises against food use[29]
Biodegradability / compostabilityNot biodegradable[24]Industrially compostable only — needs sustained 55 °C; not home compostable[38][29]
RecyclabilityMechanically recyclable but not accepted in household plastic collection[24]Mechanically recyclable; not accepted in household plastic collection[38]
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[39][20]Low hazard — minimal VOC and particle emission[39]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[39]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[39]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[39][20]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[39][20]None needed in a normal room[39]
Dust & fibre handling hazardGlass fibre is bound in the matrix; avoid inhaling sanding dust[1]Not documented
Post-Processing
Sanding & machiningSands well and takes filler before painting[24]Wet sanding — dry sanding heats the surface by friction and smears it[36][29]
Painting & finishingPaints readily after light abrasion[24]Not documented
Gluing & solvent weldingNot documentedCyanoacrylate for most joints; some grades partially dissolve and bond with acetone[29][40]
Vapour / chemical smoothingNot documentedNo practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[29]
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[41][20]PolySupport and PolyDissolve S1 (Polymaker)[3]
Dimensional accuracy & detailBambu Lab describes a smooth matte finish with micro-spot gloss that blurs layer lines[2]Not documented
Solvents & Solubility
Soluble inAcetone dissolves the resin and leaves the fibre as sludge; MEK, THF, ethyl acetate and chlorinated solvents do the same.[42][37]Chloroform: 10 % w/v in 2–4 h at 23 °C, every grade and morphology; THF and DMF only at 65 °C. Laboratory reagents.[43]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[42][44]Acetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[43][45]
Solvent welding & smoothing agentAcetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[45][37]Chloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[46][45]
