Effect of moisture on strengthPolymaker rates ABS moderate-sensitivity and publishes no dry-versus-conditioned figures; the loss appears as poor layer adhesion and surface defects rather than a stated strength delta[30]No dry-versus-conditioned figures are published; Polymaker groups the styrenics as moderate-sensitivity and absorbed water shows as bubbling and poor layer adhesion[30]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity and advises periodic drying in humid climates[30]Sealed with desiccant; Polymaker rates the styrenics moderate-sensitivity[30]

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[39][20]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[20][39]

Dust & fibre handling hazardNot documentedGlass fibre is bound in the matrix; avoid inhaling sanding dust[3]
Post-Processing
Sanding & machiningSands well and takes filler; the usual preparation before painting[19]Sands well and takes filler before painting[21]
Painting & finishingNot documentedPaints readily; ASA holds colour outdoors so many parts are left unpainted[21]

Vapour / chemical smoothingAcetone vapour smoothing works — ABS dissolves in acetone[1]Acetone vapour smoothing works[28]
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[40][20]HIPS breaks away or dissolves in d-limonene; Bambu Lab sells a Support for ABS that also serves ASA[20]
Dimensional accuracy & detailWarping and cooling-stress cracking are the accuracy limits, not shrinkage of the melt[20]Not documented
Solvents & Solubility
Soluble inAcetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[41][1]Acetone dissolves the resin and leaves the fibre; MEK, THF, ethyl acetate and chlorinated solvents attack the styrenic backbone.[41][28]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[41][42]Limonene attacks some grades — Prusa reports Prusament ASA Orange flaking apart as layer adhesion fails.[42]
Solvent welding & smoothing agentAcetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[43]Acetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[43][28]
