Part cooling fan0–20 % (Spectrum)[1]Fan on; Fiberlogy specifies 75–100 %[4][3]
Bed surface & adhesion aidPEI sheet, BuildTak or an adhesion aid such as Magigoo (Polymaker); Simplify3D also lists Kapton tape and ASA slurry[16][17]Cool plate, high-temperature plate or textured PEI with glue (Bambu Lab); smooth PEI, textured PEI or glass (Fiberlogy)[4][3]
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][18]Not documented
Warping tendency1–5Moderate — needs adhesion aid or draught shield[15]None[4]
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[16]Sticks to anything[19]
Stringing / oozing tendency1–5Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[16]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]Beginner — prints on any machine out of the box[4][3]
Extruder requirementZYLtech specifies a hardened nozzle 0.6 mm or larger; Spectrum bases its settings on a 0.5 mm nozzle[2][1]Not documented
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required — Spectrum recommends ruby or hardened, ZYLtech requires hardened[1][2]Brass fine indefinitely[20][4][3]
Abrasiveness1–5Highly abrasive — standard GF composite[1][2]Slightly abrasive — mineral filler pushes density from 1.24 to 1.31–1.38[3][4][21]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle; Prusa lists higher risk of nozzle clogging for glass-filled composites[22]Very low[20]
Heat-creep / jam sensitivity1–5Slightly sensitive[17]Moderate — good heatbreak cooling needed; PLA softens below 60 °C[23]
Hotend requirementNo special hotend required[17]No special hot-end required[19]
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[24][25][26]Moderate — 0.40 % saturated at 25 °C / 55 % RH[4]
Equilibrium moisture content at ~50 % RH%Not documented0.40 saturated at 25 °C / 55 % RH (Bambu Lab)[4]
Drying temperature & timeNot documented50 °C for 8 h in a forced-air dryer, or 60–70 °C for 12 h on an X1 heatbed; Fiberlogy specifies 50 °C for 6 h[4][3][27]
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[28]Bubbling and popping at the nozzle, stringing, rough surface and weak layers[28]
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[28]Polymaker rates PLA low-sensitivity — the loss shows as poor layer adhesion and brittle layers rather than a published strength figure[28]
Storage requirementSealed with desiccant; Polymaker rates the styrenics moderate-sensitivity[28]Sealed with desiccant below 20 % RH; shelf life at ambient is long[21][19]
Mechanical Properties
Tensile strength (XY)MPa33–36 at break, ISO 527 (ZYLtech; specimen type not stated); Spectrum quotes 55 at break on injection-moulded specimens[2][1]30 (printed XY, ISO 527, Bambu Lab); 35.1 on My Tech Fun bars for PolyTerra PLA[4][29]

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]6.3 (printed XY, ISO 179, notched); unnotched 19.2[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]Izod 6.1 kJ/m² on My Tech Fun printed bars for PolyTerra PLA[29]

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][25][24]Poor — 12 mm bar sagged to 18.7 mm over 5 days at 1.25 kg[29]
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][25][24]Poor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength (R = 0.2)[30][23]
Elasticity / flexibility1–5Rigid[2]Rigid[4]
Z strength as % of XY%Not documented73 by tensile, 55 by flexural (printed, Bambu Lab)[4]

Continuous service temperature°C93 — Prusa publishes this as the temperature resistance of Prusament ASA[31]54 — loaded bars begin to move at this temperature[29]
Annealing responseNot documented50–60 °C for 6–12 h; some prints deform or warp, and a forced-air oven is required[4]
Flammability / UL 94Flammable; no UL 94 rating published[24]Flammable; no UL 94 rating published by the major brands[21][32]
Environment & Chemical
UV resistance1–5Excellent — designed for permanent outdoor use; Spectrum states the parts resist prolonged UV and moisture exposure[1][33]Degrades within weeks outdoors[23][34]
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[25]Good against weak acids, oils and grease; poor against strong acids and alkalis; dissolved by chloroform, THF and hot benzene[32][23]
Water / humidity resistance in service1–5Not documentedGood — insoluble in water[21]
Food contactNot food safe[16]Base resin is food-contact grade, but printed layer grooves harbour bacteria; Prusa advises against food use[23]
Biodegradability / compostabilityNot biodegradable[16]Industrially compostable only — needs sustained 55 °C; not home compostable[35][23]
RecyclabilityNot accepted in household plastic collection[16]Mechanically recyclable; not accepted in household plastic collection[35]
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[36][15]Low hazard — minimal VOC and particle emission[36]
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[15][36]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration[36][15]None needed in a normal room[36]
Dust & fibre handling hazardGlass fibre is bound in the matrix; avoid inhaling sanding dust[1]Not documented
Post-Processing
Sanding & machiningSands well and takes filler before painting[16]Wet sanding — dry sanding heats the surface by friction and smears it[34][23]
Painting & finishingPaints readily; ASA holds colour outdoors so many parts are left unpainted[16]Not documented
Gluing & solvent weldingSolvent-welds with acetone[25]Cyanoacrylate for most joints; some grades partially dissolve and bond with acetone[23][37]
Vapour / chemical smoothingAcetone vapour smoothing works[25]No practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[23]
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a Support for ABS that also serves ASA[15]Support for PLA (Bambu Lab)[4]
Dimensional accuracy & detailNot documentedMatte 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.[38][25]Chloroform: 10 % w/v in 2–4 h at 23 °C, every grade and morphology; THF and DMF only at 65 °C. Laboratory reagents.[39]
Softened or crazed byLimonene attacks some grades — Prusa reports Prusament ASA Orange flaking apart as layer adhesion fails.[40]Acetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[39][41]
Solvent welding & smoothing agentAcetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[41][25]Chloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[42][41]
