Enclosure / chamber requirement1–5Enclosure recommended[14]Open frame is fine[4]
Part cooling fan0–20 % (Spectrum)[1]Fan on[4]
Bed surface & adhesion aidPEI sheet, BuildTak or an adhesion aid such as Magigoo (Polymaker); Simplify3D also lists Kapton tape and ASA slurry[15][16]Not documented
Maximum volumetric flow (mm³/s; see test conditions)mm³/s2.4–5.6 at Spectrum's 30–70 mm/s on a 0.4 mm nozzle at 0.2 mm layer; ZYLtech allows up to 200 mm/s[1][2][17]Not documented
Warping tendency1–5Moderate — needs adhesion aid or draught shield[14]Not documented
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[15]Not documented
Stringing / oozing tendency1–5Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[15]Not documented
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile; ZYLtech requires a hardened nozzle of 0.6 mm or larger[2][1]Easy — minor profile tuning; 0.2 mm nozzles are not usable[18]
Extruder requirementZYLtech specifies a hardened nozzle 0.6 mm or larger; Spectrum bases its settings on a 0.5 mm nozzle[2][1]Nozzles below 0.4 mm are not compatible (Bambu Lab)[18]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required — Spectrum recommends ruby or hardened, ZYLtech requires hardened[1][2]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[18]
Abrasiveness1–5Highly abrasive — standard GF composite[1][2]Moderately abrasive — stone fill[18][3]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle; Prusa lists higher risk of nozzle clogging for glass-filled composites[19]Moderate — needs dry filament and a clean nozzle[18]
Heat-creep / jam sensitivity1–5Slightly sensitive[16]Not documented
Hotend requirementNo special hotend required[16]Not documented
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate — the ASA matrix takes up 0.40–0.45 % saturated at 25 °C / 55 % RH; no glass-filled grade publishes its own figure[20][21][22]Moderate — 0.44 % saturated at 25 °C / 55 % RH[4]
Equilibrium moisture content at ~50 % RH%Not documented0.44 saturated at 25 °C / 55 % RH (Bambu Lab)[4]
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[23]Not documented
Effect of moisture on strengthNo dry-versus-conditioned figures are published; Polymaker groups the styrenics as moderate-sensitivity and absorbed water shows as bubbling and poor layer adhesion[23]Polymaker rates PLA low-sensitivity and publishes no dry-versus-conditioned figures for this grade; absorbed water flashes to steam and shows as bubbling and poor layer adhesion[23]
Storage requirementSealed with desiccant; Polymaker rates the styrenics moderate-sensitivity[23]Not documented
Mechanical Properties

Elongation at break%3.4 at break (ZYLtech; specimen type not stated); Spectrum quotes 2.80 at yield on injection-moulded specimens[2][1]6.7 ± 0.5 printed XY, ISO 527 (Bambu Lab)[4]

Charpy impact, notchedkJ/m²8.3 notched Charpy at 23 °C on injection-moulded specimens (Spectrum, ISO 179-1eA); ZYLtech publishes notched Izod 6.9 by ISO 180 instead[1][2]9.5 ± 2.6 printed XY, ISO 179, notched (Bambu Lab)[4]
Other impact dataCharpy unnotched 25 kJ/m² at 23 °C on injection-moulded specimens (Spectrum, ISO 179-1eU); ZYLtech notched Izod 6.9 kJ/m² (ISO 180)[1][2]Charpy unnotched 24.0 printed XY (Bambu Lab, ISO 179)[4]
Layer adhesion / Z tensileMPaNot documented30 ± 4 printed Z, ISO 527 (Bambu Lab)[4]
Brittleness1–5Brittle — snaps with little warning; elongation at break 3.4 %[2]Brittle — snaps with little warning[4]
Creep resistance / sustained load1–5Good — no creep test found; chopped glass fibre lifts modulus to 2540–2890 against 2379–2450 for unfilled ASA[2][21][20]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[24][25][26]
Fatigue / repeated-flex resistance1–5Below average — no GF-grade S-N curve; elongation at break falls to 3.4 % against 6.7–9.2 % for unfilled ASA[2][21][20]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[27][4]
Elasticity / flexibility1–5Rigid[2]Rigid[4]
Z strength as % of XY%Not documented91 by tensile, 73 by flexural (printed, Bambu Lab)[4]

Continuous service temperature°C93 — Prusa publishes this as the temperature resistance of Prusament ASA[28]Not documented
Flammability / UL 94Flammable; no UL 94 rating published[20]Not documented
Environment & Chemical
UV resistance1–5Excellent — designed for permanent outdoor use; Spectrum states the parts resist prolonged UV and moisture exposure[1][29]Degrades within weeks outdoors[30]
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[21]Not documented
Food contactNot food safe[15]Not documented
Biodegradability / compostabilityNot biodegradable[15]Not documented
RecyclabilityNot accepted in household plastic collection[15]Not documented
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[31][14]Low hazard — minimal VOC and particle emission[31]
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[14][31]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration[31][14]None needed in a normal room[31]
Dust & fibre handling hazardGlass fibre is bound in the matrix; avoid inhaling sanding dust[1]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[3]
Post-Processing
Sanding & machiningSands well and takes filler before painting[15]Sands to a stone-like matte surface[3]
Painting & finishingPaints readily; ASA holds colour outdoors so many parts are left unpainted[15]Not documented
Gluing & solvent weldingSolvent-welds with acetone[21]Not documented
Vapour / chemical smoothingAcetone vapour smoothing works[21]Not documented
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a Support for ABS that also serves ASA[14]Support for PLA (Bambu Lab)[4]
Dimensional accuracy & detailNot documentedMatte mineral surface hides layer lines; 55° overhangs and 30 mm bridges as for plain PLA[4]
Solvents & Solubility
Soluble inAcetone dissolves the resin and leaves the fibre; MEK, THF, ethyl acetate and chlorinated solvents attack the styrenic backbone.[32][21]Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[33]
Softened or crazed byLimonene attacks some grades — Prusa reports Prusament ASA Orange flaking apart as layer adhesion fails.[34]Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[33][35]
Solvent welding & smoothing agentAcetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[35][21]Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[36][35]
