Shrinkage%Not documented0.05 in X-Y and Z, 0.10 diagonal (Polymaker HT-PLA-GF)[4]
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile; the hotter nozzle rules out PTFE-lined hotends[1][2]Intermediate — dry filament and a tuned profile; hardened nozzle mandatory[4]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[12]Hardened steel required[4]
Abrasiveness1–5Non-abrasive[12]Highly abrasive — standard GF composite[4]
Nozzle clog risk1–5Low — unfilled ABS compound; no special hot-end required and clogging is not among the listed drawbacks[13][16]Moderate — needs dry filament and a clean nozzle; Prusa lists higher risk of nozzle clogging for glass-filled composites[17]
Heat-creep / jam sensitivity1–5Slightly sensitive[13]Not documented

Environment & Chemical
UV resistance1–5Months outdoors before embrittlement[15]Degrades within weeks outdoors[27]
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[3]Not documented
Food contactNot food safe — Polymaker cites potential chemical leaching[15]Not documented
Biodegradability / compostabilityNot biodegradable[15]Not documented
RecyclabilityMechanically recyclable but not accepted in household plastic collection[15]Not documented
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[28][12]Low hazard — minimal VOC and particle emission[28]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[28]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[28]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[28][12]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[28][12]None needed in a normal room[28]
Dust & fibre handling hazardNot documentedGlass fibre is bound in the matrix; avoid inhaling sanding dust[29]
Post-Processing
Sanding & machiningSands well and takes filler before painting[15]Not documented
Painting & finishingPaints readily after light abrasion[15]Not documented
Vapour / chemical smoothingAcetone vapour smoothing works[3]Not documented
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[30][12]Not documented
Dimensional accuracy & detailNot documentedNear-zero shrinkage — 0.05 % in X-Y and Z (Polymaker)[4]
Solvents & Solubility
Soluble inAcetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[31][3]Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[32]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[31][33]Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[32][34]
Solvent welding & smoothing agentAcetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[34]Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[35][34]
