Brittleness1–5Moderate[1]Moderate[2]
Creep resistance / sustained load1–5Moderate — no creep test found; Tg of 105 °C keeps room-temperature service far below softening[1]Below average — no creep test found; the foamed structure drops modulus to 2010 MPa and load is carried by a lower solid fraction[2][17]
Fatigue / repeated-flex resistance1–5Below average — no S-N curve found; elongation at break 4 %, well below unfilled ABS[1][19]Moderate — no foamed-grade S-N curve; unfilled printed ASA holds a fatigue limit at 25 % of tensile strength[2][20]

Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[25][8]High — hazardous VOC such as styrene; enclosure and filtration needed[25][8]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[25]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[25]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[25][8]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[8][25]
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[25][8]Enclosure with carbon and HEPA filtration[25][8]
Dust & fibre handling hazardConductive carbon filler is bound in the matrix; avoid inhaling sanding dust[1]Not documented
Post-Processing
Sanding & machiningSands well and takes filler before painting[13]Sands well and takes filler before painting[10]
Painting & finishingPaints readily after light abrasion[13]Paints readily; ASA holds colour outdoors so many parts are left unpainted[10]
Gluing & solvent weldingNot documentedSolvent-welds with acetone[24]
Vapour / chemical smoothingNot documentedAcetone vapour smoothing works[24]
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[26][8]HIPS breaks away or dissolves in d-limonene; Bambu Lab sells a Support for ABS that also serves ASA[8]
Dimensional accuracy & detailNot documentedMatte, textured surface that hides layer lines; colour lightens as the foaming degree rises, which doubles as a visual density cue[3]
Solvents & Solubility
Soluble inAcetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[27][23]Acetone dissolves it (Polymaker); MEK, THF, ethyl acetate and the chlorinated solvents dissolve the styrenic backbone.[27][24]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[27][28]Limonene attacks some grades — Prusa reports Prusament ASA Orange flaking apart as layer adhesion fails.[28]
Solvent welding & smoothing agentAcetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[29]Acetone vapour, ~20 min at 80 °C over 5 mm of liquid; the foamed wall absorbs solvent, so cut the exposure well short.[29]
