Typical applicationsLarge or repetitive prints on printers that can sustain high flow[17][15]Chemical and automotive parts needing PPS chemistry with structural stiffness[3]
Diameter tolerance± mm±0.03 (Bambu Lab PLA Basic, rated to 258 mm/s)[18]Not documented
Printing Parameters
Nozzle temperature°C210–230 for high-speed work; 190–210 at classic speeds[1][15]Not documented
Bed temperature°C30–60 (Polymaker); 35–45 (Bambu Lab)[1][19]Not documented
Enclosure / chamber requirement1–5Open frame is fine[1]Enclosure required (passive) — Polymaker states its Fiberon PPS-CF10 needs no heated chamber, unlike the unfilled sulfones and PAEKs[3]
Part cooling fanFan on[1]Not documented
Maximum volumetric flow (mm³/s; see test conditions)mm³/s≈24 at 300 mm/s with a 0.4 mm nozzle and 0.2 mm layer; 30 % more flow than regular PLA at the same temperature[1][15][17][20]Not documented
Warping tendency1–5None[1]Not documented
Bed-adhesion difficulty1–5Sticks to anything[21]Not documented
Overall printing difficulty1–5Easy — minor profile tuning; needs a printer that can actually reach the flow rate[15][1]Expert / industrial hardware only[3]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[22]Hardened steel required[3]
Abrasiveness1–5Non-abrasive[23][22]Highly abrasive — standard CF composite[3]
Nozzle clog risk1–5Very low[22]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 sensitivity1–5Moderate — good heatbreak cooling needed; PLA softens below 60 °C[26]Not documented
Hotend requirementNo special hot-end required[21]Not documented
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate — 0.40 % equilibrium at 23 °C / 70 % RH[1]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%0.40 equilibrium at 23 °C / 70 % RH (Polymaker PolySonic)[1]0.225 equilibrium (Fiberon PPS-CF10); 0.11 (PPS-GF20)[3][4]
Drying temperature & time55 °C for 6 h; 50 °C for 8 h (Bambu Lab)[1][19]Not documented
Symptoms when wetBubbling and popping at the nozzle, stringing, rough surface and weak layers[27]Not documented
Effect of moisture on strengthPolymaker rates PLA low-sensitivity — the loss shows as poor layer adhesion and brittle layers rather than a published strength figure[27]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 below 20 % RH; shelf life at ambient is long[19][21]Not documented
Mechanical Properties
Tensile strength (XY)MPa43.9 at 300 mm/s and 46.0 at 46.7 mm/s (printed XY, ISO 527); 58.6 on My Tech Fun bars for Creality Hyper PLA[1][28]59.4 ± 1.3 (PPS-CF10) and 64.1 ± 2.1 (PPS-GF20) printed XY, ISO 527[3][4]
Young's modulusMPa2650 at 300 mm/s, 2878 at classic speed (printed XY, ISO 527)[1]5446.7 ± 149.0 (PPS-CF10) and 4552.0 ± 54.6 (PPS-GF20) printed XY, ISO 527[3][4]
Elongation at break%15.1 at 300 mm/s, 21.5 at classic speed (printed XY, ISO 527)[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 strengthMPa71.4 at 300 mm/s, 76.5 at classic speed (printed XY, ISO 178)[1]Not documented
Flexural modulusMPa2798 at 300 mm/s, 2868 at classic speed (printed XY, ISO 178)[1]Not documented
Charpy impact, notchedkJ/m²5.0 at 300 mm/s, 6.1 at classic speed (printed XY, ISO 179, notched)[1]5.3 ± 0.2 printed XY for PPS-CF10 and 7.3 ± 0.2 for PPS-GF20, ISO 179 notched[3][4]
Other impact dataPrinting at 300 mm/s instead of 46.7 mm/s costs 4.6 % tensile strength and 18 % notched Charpy[1]Not documented
Layer adhesion / Z tensileMPa32.4 at 300 mm/s, 37.3 at classic speed (printed Z, ISO 527); 35.3 for Creality Hyper PLA vs 23.0 for average PLA on identical bars[1][28]32.0 ± 5.1 (PPS-CF10) and 22.9 ± 0.8 (PPS-GF20) printed Z, ISO 527[3][4]
Brittleness1–5Moderate[1]Very brittle — cracks or shatters easily; elongation at break 1.4 %[3]
Hardness (scale-specific)Shore A / Shore D / Rockwell78.7 Shore D measured on printed bars for Sunlu PLA Meta (My Tech Fun), against 75.3 for the same maker's plain PLA[29]Rockwell 105 (and R124) on extruded unfilled PPS stock (ASTM D785); no figure is published for a fibre-filled PPS filament[30]
Creep resistance / sustained load1–5Poor — 12 mm bar sagged to 17.7 mm over 6 days at 1.25 kg[28]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[30][31][3]
Fatigue / repeated-flex resistance1–5Poor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength (R = 0.2)[32][26]Not documented

Thermal expansion (CTE)µm/m·K96–99 for plain printed PLA (fibre Bragg grating, 25–50 °C); no grade-specific measurement published[33]Not documented
Flammability / UL 94Flammable; no UL 94 rating published by the major brands[19][2]Not documented
Environment & Chemical
UV resistance1–5Degrades within weeks outdoors[26][34]Not documented
Chemical resistanceGood against weak acids, oils and grease; poor against strong acids and alkalis[1]Outstanding — PPS resists essentially all solvents below 200 °C[24]
Water / humidity resistance in service1–5Good — insoluble in water[19]Not documented
Food contactBase resin is food-contact grade, but printed layer grooves harbour bacteria; Prusa advises against food use[26]Not documented
Biodegradability / compostabilityIndustrially compostable only — needs sustained 55 °C; not home compostable[35][26]Not documented
RecyclabilityMechanically recyclable; not accepted in household plastic collection[35]Not documented
Electrical & ESD propertiesNot documentedSurface resistivity above 10¹² ohm — insulating (ANSI/ESD S11.11)[3][4]
Health & Safety
Fume toxicity1–5Low hazard — minimal VOC and particle emission[36]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[36]
Ventilation / filtration requirement1–5None needed in a normal room[36]Ventilated room or enclosure recommended[36]
Dust & fibre handling hazardNot documentedFibre is bound in the matrix; sanding dust should not be inhaled[3]
Post-Processing
Sanding & machiningWet sanding — dry sanding heats the surface by friction and smears it[34][26]Not documented
Gluing & solvent weldingCyanoacrylate for most joints; some grades partially dissolve and bond with acetone[26][37]Not documented
Vapour / chemical smoothingNo practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[26]Not documented
Support material pairingPolySupport and PolyDissolve S1 (Polymaker)[1]Not documented
Solvents & Solubility
Soluble inChloroform: 10 % w/v in 2–4 h at 23 °C, every grade and morphology; THF and DMF only at 65 °C. Laboratory reagents.[38]None — PPS does not dissolve in any known solvent below 200 °C.[39][40]
Softened or crazed byAcetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[38][41]Nothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[40]
Solvent welding & smoothing agentChloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[42][41]None — no solvent welds or smooths PPS.[39]
