Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[30][14]High — hazardous VOC such as styrene; enclosure and filtration needed[30][14]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[30]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[30]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[30][14]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[14][30]

Post-Processing
Sanding & machiningSands well and takes filler before painting[19]Sands well and takes filler before painting[16]
Painting & finishingPaints readily after light abrasion[19]Paints readily; ASA holds colour outdoors so many parts are left unpainted[16]

Dimensional accuracy & detailNot documentedMatte fibre-filled finish hides layer lines[4]
Solvents & Solubility
Soluble inAcetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[32][3]Acetone dissolves the resin and leaves the fibre; MEK, THF, ethyl acetate and chlorinated solvents attack the styrenic backbone.[32][25]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[32][33]Limonene attacks some grades — Prusa reports Prusament ASA Orange flaking apart as layer adhesion fails.[33]
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]Acetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[34][25]
