Extruder requirementNot documentedNozzles below 0.4 mm are not compatible (Bambu Lab)[20]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[16]Brass acceptable; hardened steel for volume work — Bambu Lab's compatibility table says no hardened nozzle is needed while the note under the same table groups PLA Marble with particle-filled materials that should always use one[20]
Abrasiveness1–5Highly abrasive — standard CF composite[16]Moderately abrasive — stone fill[20][4]

Charpy impact, notchedkJ/m²6.2 ± 1.4 printed XY, ISO 179, notched (Bambu Lab) — a third of unfilled Bambu Lab ASA's 19.6[1][24]9.5 ± 2.6 printed XY, ISO 179, notched (Bambu Lab)[5]
Other impact dataCharpy unnotched 14.0 ± 2.2 printed XY (Bambu Lab, ISO 179), against 41.0 for unfilled Bambu Lab ASA[1][24]Charpy unnotched 24.0 printed XY (Bambu Lab, ISO 179)[5]
Layer adhesion / Z tensileMPa30 ± 4 printed Z, ISO 527 (Bambu Lab); flexural Z falls to 33 against 72 in XY[1]30 ± 4 printed Z, ISO 527 (Bambu Lab)[5]
Brittleness1–5Brittle — snaps with little warning[1][2]Brittle — snaps with little warning[5]
Creep resistance / sustained load1–5Good — no creep test found; chopped carbon fibre lifts modulus to 4200 MPa against 2379–2450 for unfilled ASA[1][25]Poor — no stone-filled creep test; plain printed PLA sagged from 12 to 16.2–21.8 mm over 5 days at 1.25 kg[26][27][28]
Fatigue / repeated-flex resistance1–5Below average — no CF-grade S-N curve; notched Charpy falls to 6.2 kJ/m² against 19.6 for unfilled Bambu Lab ASA[1][24]Poor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength and the mineral filler leaves a brittle compound[29][5]
Elasticity / flexibility1–5Rigid[1]Rigid[5]

Melting point / Vicat°CNot documented156 peak melt (DSC); Formfutura gives a 120–170 melting range for StoneFil[5][4]
Continuous service temperature°C93 — Prusa publishes this as the temperature resistance of Prusament ASA[30]Not documented
Flammability / UL 94Flammable; no UL 94 rating published[24]Not documented
Environment & Chemical
UV resistance1–5Excellent — designed for permanent outdoor use; the acrylate rubber phase is unchanged by the fibre[31][17]Degrades within weeks outdoors[32]
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[25]Not documented
Food contactNot food safe[17]Not documented
Biodegradability / compostabilityNot biodegradable[17]Not documented
RecyclabilityNot accepted in household plastic collection[17]Not documented
Electrical & ESD propertiesSurface resistance above 10⁹ ohm/sq — not static-dissipative (3DXTech, ASTM D257)[2]Not documented
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[33][16]Low hazard — minimal VOC and particle emission[33]
Hazardous species emittedStyrene. 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[16][33]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration[33][16]None needed in a normal room[33]
Dust & fibre handling hazardCarbon fibre is bound in the matrix; sanding dust should not be inhaled[2]Formfutura's SDS sets an occupational limit of 1 mg/m³ for the stone powder and lists it as both a fibre and a particulate — do not dry-sand without extraction[4]
Post-Processing
Sanding & machiningSands well and takes filler before painting[17]Sands to a stone-like matte surface[4]
Painting & finishingPaints readily; ASA holds colour outdoors so many parts are left unpainted[17]Not documented
Gluing & solvent weldingSolvent-welds with acetone[25]Not documented
Vapour / chemical smoothingAcetone vapour smoothing works[25]Not documented
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a Support for ABS that also serves ASA[16]Support for PLA (Bambu Lab)[5]
Dimensional accuracy & detailMatte fibre-filled finish hides layer lines[1]Matte mineral surface hides layer lines; 55° overhangs and 30 mm bridges as for plain PLA[5]
Solvents & Solubility
Soluble inAcetone dissolves the resin and leaves the fibre; MEK, THF, ethyl acetate and chlorinated solvents attack the styrenic backbone.[34][25]Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[35]
Softened or crazed byLimonene attacks some grades — Prusa reports Prusament ASA Orange flaking apart as layer adhesion fails.[36]Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[35][37]
Solvent welding & smoothing agentAcetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[37][25]Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[38][37]
