Part cooling fan0–20 % (Spectrum)[1]Not documented
Bed surface & adhesion aidPEI sheet, BuildTak or an adhesion aid such as Magigoo (Polymaker); Simplify3D also lists Kapton tape and ASA slurry[13][14]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][15]Not documented
Warping tendency1–5Moderate — needs adhesion aid or draught shield[12]Not documented
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[13]Not documented
Stringing / oozing tendency1–5Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[13]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]Expert / industrial hardware only[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

Abrasiveness1–5Highly abrasive — standard GF composite[1][2]Highly abrasive — standard CF composite[3]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle; Prusa lists higher risk of nozzle clogging for glass-filled composites[16]High — jams from moisture, heat creep or particles; Polymaker specifies hardened steel or ruby nozzles for carbon-filled PPS and Prusa lists composites as a higher clogging risk[17][16]
Heat-creep / jam sensitivity1–5Slightly sensitive[14]Not documented
Hotend requirementNo special hotend required[14]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[18][19][20]Low (0.1–0.3 %) — 0.225 % equilibrium for Fiberon PPS-CF10 and 0.11 % for PPS-GF20[3][4]
Equilibrium moisture content at ~50 % RH%Not documented0.225 equilibrium (Fiberon PPS-CF10); 0.11 (PPS-GF20)[3][4]
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[21]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[21]No dry-versus-conditioned figures are published; equilibrium uptake is 0.225 % and Polymaker specifies a 100 °C, 10 h dry[3]
Storage requirementSealed with desiccant; Polymaker rates the styrenics moderate-sensitivity[21]Not documented
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]59.4 ± 1.3 (PPS-CF10) and 64.1 ± 2.1 (PPS-GF20) printed XY, ISO 527[3][4]
Young's modulusMPa2540–2890 (ZYLtech; specimen type not stated) and 2550 (Spectrum, injection-moulded), ISO 527[2][1]5446.7 ± 149.0 (PPS-CF10) and 4552.0 ± 54.6 (PPS-GF20) printed XY, ISO 527[3][4]
Elongation at break%3.4 at break (ZYLtech; specimen type not stated); Spectrum quotes 2.80 at yield on injection-moulded specimens[2][1]1.4 ± 0.1 (PPS-CF10) and 2.0 ± 0.2 (PPS-GF20) printed XY, ISO 527 — the lowest elongation in the dataset[3][4]
Flexural modulusMPa2130–2480 flexural modulus, ISO 178 (ZYLtech; specimen type not stated)[2]Not documented
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]5.3 ± 0.2 printed XY for PPS-CF10 and 7.3 ± 0.2 for PPS-GF20, ISO 179 notched[3][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]Not documented
Layer adhesion / Z tensileMPaNot documented32.0 ± 5.1 (PPS-CF10) and 22.9 ± 0.8 (PPS-GF20) printed Z, ISO 527[3][4]
Brittleness1–5Brittle — snaps with little warning; elongation at break 3.4 %[2]Very brittle — cracks or shatters easily; elongation at break 1.4 %[3]
Hardness (scale-specific)Shore A / Shore D / RockwellNot documentedRockwell 105 (and R124) on extruded unfilled PPS stock (ASTM D785); no figure is published for a fibre-filled PPS filament[22]
Creep resistance / sustained load1–5Good — no creep test found; chopped glass fibre lifts modulus to 2540–2890 against 2379–2450 for unfilled ASA[2][19][18]Excellent — holds load for years. Ensinger lists high creep resistance for unfilled PPS stock and Spectrum states creep resistance is unchanged under continuous load at high temperature; the fibre raises heat deflection to 252 °C at 0.45 MPa[22][23][3]
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][19][18]Not documented

Continuous service temperature°C93 — Prusa publishes this as the temperature resistance of Prusament ASA[24]170 long-term service on extruded PPS stock, converted from 338 °F; no figure published for the carbon-filled grade[22]
Flammability / UL 94Flammable; no UL 94 rating published[18]Not documented
Environment & Chemical
UV resistance1–5Excellent — designed for permanent outdoor use; Spectrum states the parts resist prolonged UV and moisture exposure[1][25]Not documented
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[19]Outstanding — PPS resists essentially all solvents below 200 °C[17]
Food contactNot food safe[13]Not documented
Biodegradability / compostabilityNot biodegradable[13]Not documented
RecyclabilityNot accepted in household plastic collection[13]Not documented
Electrical & ESD propertiesNot documentedSurface resistivity above 10¹² ohm — insulating (ANSI/ESD S11.11)[3][4]
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[26][12]Moderate — measurable VOCs and UFPs, ventilation advised. None of these polymers was in the chamber study, and all are processed far above the temperatures it covered[26]
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[12][26]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration[26][12]Ventilated room or enclosure recommended[26]
Dust & fibre handling hazardGlass fibre is bound in the matrix; avoid inhaling sanding dust[1]Fibre is bound in the matrix; sanding dust should not be inhaled[3]
Post-Processing
Sanding & machiningSands well and takes filler before painting[13]Not documented
Painting & finishingPaints readily; ASA holds colour outdoors so many parts are left unpainted[13]Not documented
Gluing & solvent weldingSolvent-welds with acetone[19]Not documented
Vapour / chemical smoothingAcetone vapour smoothing works[19]Not documented
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a Support for ABS that also serves ASA[12]Not documented
Solvents & Solubility
Soluble inAcetone dissolves the resin and leaves the fibre; MEK, THF, ethyl acetate and chlorinated solvents attack the styrenic backbone.[27][19]None — PPS does not dissolve in any known solvent below 200 °C.[28][27]
Softened or crazed byLimonene attacks some grades — Prusa reports Prusament ASA Orange flaking apart as layer adhesion fails.[29]Nothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[27]
Solvent welding & smoothing agentAcetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[30][19]None — no solvent welds or smooths PPS.[28]
