Bambu Lab states ABS and ASA release harmful gases such as styrene at printing temperature, which can be toxic and cause dizziness or nausea[33][15]Styrene. Bambu Lab states ABS and ASA release harmful gases such as styrene at printing temperature, which can be toxic and cause dizziness or nausea. Azimi et al. measured styrene from every styrenic filament tested but did not test ASA itself[15][33]
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[33][15]Enclosure with carbon and HEPA filtration[33][15]

Post-Processing
Sanding & machiningSands well and takes filler before painting[20]Sands well and takes filler before painting[17]
Painting & finishingPaints readily after light abrasion[20]Paints readily; ASA holds colour outdoors so many parts are left unpainted[17]

Vapour / chemical smoothingAcetone smoothing is blunted by the fibre — only the resin fraction dissolves[32]Acetone vapour smoothing works[28]
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[34][15]HIPS breaks away or dissolves in d-limonene; Bambu Lab sells a Support for ABS that also serves ASA[15]
Dimensional accuracy & detailNot documentedMatte fibre-filled finish hides layer lines[2]
Solvents & Solubility
Soluble inAcetone dissolves the resin and leaves the fibre as sludge; MEK, THF, ethyl acetate and chlorinated solvents do the same.[35][32]Acetone dissolves the resin and leaves the fibre; MEK, THF, ethyl acetate and chlorinated solvents attack the styrenic backbone.[35][28]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[35][36]Limonene attacks some grades — Prusa reports Prusament ASA Orange flaking apart as layer adhesion fails.[36]
Solvent welding & smoothing agentAcetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[37][32]Acetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[37][28]
