Printing Parameters
Nozzle temperature°C230–270 across brands; Prusament 260 ± 10, Bambu Lab 240–270, PolyLite 230–260[4][5][2]Not documented
Bed temperature°C75–110; Prusament 110 ± 5, Bambu Lab 80–100, PolyLite 75–95[4][5][2]Not documented
Enclosure / chamber requirement1–5Enclosure recommended — Polymaker calls a chamber needed at ambient temperature, Bambu Lab requires an enclosed printer and rules out its P1P and A-series machines[5][20]Enclosure required (passive) — Polymaker states its Fiberon PPS-CF10 needs no heated chamber, unlike the unfilled sulfones and PAEKs[3]
Recommended chamber temperature°C45–60 (Bambu Lab)[4]Not documented
Part cooling fanLow — Prusament 30 % within a 0–50 % range, Bambu Lab 0–80 %, PolyLite off[2][4][5]Not documented
Bed surface & adhesion aidSatin, smooth PEI or powder-coated sheet with a glue stick; Prusa advises a 3 mm or taller brim on large parts[2][20]Not documented
Maximum volumetric flow (mm³/s; see test conditions)mm³/s10–16 (PrusaSlicer guidance for ABS/ASA)[21]Not documented
Warping tendency1–5High — enclosure needed for reliable large parts; Prusa recommends a tall brim and Bambu Lab attributes cracking to cooling stress exceeding interlayer adhesion[2][20]Not documented
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[2][20]Not documented
Stringing / oozing tendency1–5Slight[5]Not documented
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile[20][2]Expert / industrial hardware only[3]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[20]Hardened steel required[3]
Abrasiveness1–5Non-abrasive[20]Highly abrasive — standard CF composite[3]
Nozzle clog risk1–5Low — no special hot-end required and clogging is not among the listed drawbacks; Prusa lists no drybox and no hardened nozzle[22][23]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[24][25]
Heat-creep / jam sensitivity1–5Slightly sensitive[22]Not documented
Hotend requirementNo special hot-end required[22]Not documented
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate — 0.45 % saturated at 25 °C / 55 % RH (Bambu Lab) and 0.40 % equilibrium (Polymaker); Prusa measures only 0.17 % after 7 days at 22 % RH[4][5][2]Low (0.1–0.3 %) — 0.225 % equilibrium for Fiberon PPS-CF10 and 0.11 % for PPS-GF20[3][6]
Equilibrium moisture content at ~50 % RH%0.45 saturated at 25 °C / 55 % RH (Bambu Lab); 0.40 equilibrium (Polymaker); 0.17 after 7 days at 24 °C / 22 % RH (Prusa)[4][5][2]0.225 equilibrium (Fiberon PPS-CF10); 0.11 (PPS-GF20)[3][6]
Drying temperature & time80 °C for 8 h (Bambu Lab); 70 °C for 7 h (Polymaker)[4][5]Not documented
Symptoms when wetBubbling and popping at the nozzle, stringing, rough surface and weak layers[26]Not documented
Effect of moisture on strengthNo dry-versus-conditioned figures are published for ASA; Polymaker groups the styrenics as moderate-sensitivity and the loss shows as poor layer adhesion rather than a stated strength delta[26]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[26]Not documented

Elongation at break%6.7 (PolyLite) to 9.2 (Bambu Lab) at break, printed XY, ISO 527; Formfutura quotes 15 at break, Prusament 3.4 at yield[4][5][27][2]1.4 ± 0.1 (PPS-CF10) and 2.0 ± 0.2 (PPS-GF20) printed XY, ISO 527 — the lowest elongation in the dataset[3][6]
Flexural strengthMPa64 ± 1 printed horizontal (Prusament, ISO 178); Bambu Lab 65 ± 5, PolyLite 73.4[2][4][5]Not documented
Flexural modulusMPa1920 ± 130 (Bambu Lab) to 3206 (PolyLite) printed XY, ISO 178; Prusament 2000[4][5][2]Not documented
Charpy impact, notchedkJ/m²10.3 (PolyLite) to 19.6 (Bambu Lab) printed XY, ISO 179, notched; Prusament 12 ± 1, Formfutura 18[5][4][2][27]5.3 ± 0.2 printed XY for PPS-CF10 and 7.3 ± 0.2 for PPS-GF20, ISO 179 notched[3][6]

Layer adhesion / Z tensileMPa11 ± 1 (Prusa interlayer adhesion test); 31 ± 4 (Bambu Lab) and 32 (PolyLite) printed Z tensile, ISO 527[2][4][5]32.0 ± 5.1 (PPS-CF10) and 22.9 ± 0.8 (PPS-GF20) printed Z, ISO 527[3][6]
Brittleness1–5Tough — absorbs impact, yields before breaking[4][2]Very brittle — cracks or shatters easily; elongation at break 1.4 %[3]
Hardness (scale-specific)Shore A / Shore D / Rockwell78 Shore D (Prusa Polymers method)[2]Rockwell 105 (and R124) on extruded unfilled PPS stock (ASTM D785); no figure is published for a fibre-filled PPS filament[28]
Creep resistance / sustained load1–5Moderate — no printed-ASA creep test found; Tg of 98 °C keeps room-temperature service far below softening, unlike PLA[5][2]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[28][29][3]
Fatigue / repeated-flex resistance1–5Moderate — fatigue limit at 25 % of tensile strength (8 MPa) on printed specimens, the best of the four polymers in that study[30]Not documented

Environment & Chemical
UV resistance1–5Excellent — designed for permanent outdoor use. After 1000 h of QUV exposure to ASTM G154 Stratasys measured yield strength falling only from 30.5 to 30.3 MPa and stress at break by 3.0 %[19]Not documented
Outdoor durability1000 h QUV per ASTM G154, cycling 8 h at 60 °C and 4 h at 50 °C with condensation: yield 30.5 → 30.3 MPa, stress at break 30.5 → 29.5 MPa, elongation 2.8 → 2.3 %, modulus 1.82 → 1.95 GPa[19]Not documented
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[5]Outstanding — PPS resists essentially all solvents below 200 °C[24]
Water / humidity resistance in service1–5Good — minor absorption[4]Not documented
Food contactNot food safe[1]Not documented
Biodegradability / compostabilityNot biodegradable[1]Not documented
RecyclabilityNot accepted in household plastic collection[1]Not documented
Electrical & ESD propertiesNot documentedSurface resistivity above 10¹² ohm — insulating (ANSI/ESD S11.11)[3][6]
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[33][20]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[33]
VOC emission rateµg/min12–113 styrene, the range measured across the styrenic filaments tested; ASA itself was not among them[33]Not documented
Ultrafine-particle emission rateparticles/min2 × 10¹⁰ to 9 × 10¹⁰ median for ABS, the closest styrenic tested; ASA itself was not measured[33]Not documented
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[20][33]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration[33][20]Ventilated room or enclosure recommended[33]
Dust & fibre handling hazardNot documentedFibre is bound in the matrix; sanding dust should not be inhaled[3]
Post-Processing
Sanding & machiningSands well and takes filler before painting[1]Not documented
Gluing & solvent weldingSolvent-welds with acetone[5]Not documented
Vapour / chemical smoothingAcetone vapour smoothing works — ASA dissolves in acetone[5]Not documented
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS that also serves ASA[20]Not documented
Dimensional accuracy & detailWarping and cooling-stress cracking are the accuracy limits; Stratasys notes the matte finish as a deliberate aesthetic advantage[20][19]Not documented
Solvents & Solubility
Soluble inAcetone dissolves it (Polymaker); MEK, THF, ethyl acetate and the chlorinated solvents dissolve the styrenic backbone.[34][5]None — PPS does not dissolve in any known solvent below 200 °C.[35][34]
Softened or crazed byLimonene attacks some grades — Prusa reports Prusament ASA Orange flaking apart as layer adhesion fails.[36]Nothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[34]
Solvent welding & smoothing agentAcetone vapour, ~20 min at 80 °C over 5 mm of liquid (15–40 min across brands); layer adhesion up, tensile slightly down.[37]None — no solvent welds or smooths PPS.[35]
