Food contactNot food safe — Polymaker cites potential chemical leaching[22]Not documented
Biodegradability / compostabilityNot biodegradable[22]Not documented
RecyclabilityMechanically recyclable but not accepted in household plastic collection[22]Not documented
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[34][18]Low hazard — minimal VOC and particle emission[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][18]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[34][18]None needed in a normal room[34]
Dust & fibre handling hazardGlass fibre is bound in the matrix; avoid inhaling sanding dust[1]Carbon fibre is bound in the matrix; sanding dust should not be inhaled[3]
Post-Processing
Sanding & machiningSands well and takes filler before painting[22]Not documented
Painting & finishingPaints readily after light abrasion[22]Not documented
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[35][18]Support for PLA (Bambu Lab); PolySupport and PolyDissolve S1 (Polymaker)[5][4]
Dimensional accuracy & detailBambu Lab describes a smooth matte finish with micro-spot gloss that blurs layer lines[2]Matte finish hides layer lines; stiffness is the gain — tensile strength stays at or below Bambu Lab PLA Basic's 35 MPa and Polymaker PolyLite PLA's 52.3 MPa[5][4][36][37]
Solvents & Solubility
Soluble inAcetone dissolves the resin and leaves the fibre as sludge; MEK, THF, ethyl acetate and chlorinated solvents do the same.[38][33]Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[39]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[38][40]Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[39][41]
Solvent welding & smoothing agentAcetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[41][33]Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[42][41]
