Printing Parameters
Nozzle temperature°C270 ± 10 (Prusament)[1]Not documented
Bed temperature°C85 ± 10 (Prusament)[1]Not documented
Enclosure / chamber requirement1–5Enclosure recommended — Simplify3D lists an enclosure as a hardware requirement and Polymaker advises one below 70 °C ambient to stop warping and cracking[14][15]Enclosure required (passive) — Polymaker states its Fiberon PPS-CF10 needs no heated chamber, unlike the unfilled sulfones and PAEKs[3]
Part cooling fanOff — Prusa runs 0 % except 100 % on bridges[1]Not documented

Warping tendency1–5High — enclosure needed for reliable large parts; Prusa recommends a brim[1]Not documented
Bed-adhesion difficulty1–5Very difficult — special plates or slurry required[1]Not documented
Overall printing difficulty1–5Advanced — enclosure, hardware upgrades, tuning; hardened nozzle mandatory[1]Expert / industrial hardware only[3]
Extruder requirementPrusa states a hardened nozzle is necessary and recommends a brim[1]Not documented
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required — Prusa states plainly that a hardened nozzle is necessary[1]Hardened steel required[3]
Abrasiveness1–5Highly abrasive — standard CF composite[1]Highly abrasive — standard CF composite[3]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle; 3DXTech specifies a hardened 0.4 mm minimum nozzle and 0.25 mm layers or higher, and Prusa lists composites as a higher clogging risk[2][17]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[18][17]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Negligible (<0.1 % EMC) — Prusa measures 0.03 % in 24 h and 0.04 % in 7 days on its PP composite, the lowest figures it publishes for any filament[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%0.03 after 24 h and 0.04 after 7 days at 24 °C / 22 % RH (Prusa Polymers)[1]0.225 equilibrium (Fiberon PPS-CF10); 0.11 (PPS-GF20)[3][4]
Effect of moisture on strengthNot applicable in practice at 0.04 % equilibrium uptake[1]No dry-versus-conditioned figures are published; equilibrium uptake is 0.225 % and Polymaker specifies a 100 °C, 10 h dry[3]
Storage requirementNo special storage needed[1]Not documented
Mechanical Properties
Tensile strength (XY)MPa21 ± 0.4 filament tensile yield (Prusament, ISO 527)[1]59.4 ± 1.3 (PPS-CF10) and 64.1 ± 2.1 (PPS-GF20) printed XY, ISO 527[3][4]
Young's modulusMPaNot documented5446.7 ± 149.0 (PPS-CF10) and 4552.0 ± 54.6 (PPS-GF20) printed XY, ISO 527[3][4]
Elongation at break%Not documented1.4 ± 0.1 (PPS-CF10) and 2.0 ± 0.2 (PPS-GF20) printed XY, ISO 527 — the lowest elongation in the dataset[3][4]
Charpy impact, notchedkJ/m²14.5 ± 0.3 printed horizontal and 10.5 ± 0.8 printed vertical XZ (ISO 179-1, notched)[1]5.3 ± 0.2 printed XY for PPS-CF10 and 7.3 ± 0.2 for PPS-GF20, ISO 179 notched[3][4]
Layer adhesion / Z tensileMPaNot documented32.0 ± 5.1 (PPS-CF10) and 22.9 ± 0.8 (PPS-GF20) printed Z, ISO 527[3][4]
Brittleness1–5Tough — absorbs impact, yields before breaking[1]Very brittle — cracks or shatters easily; elongation at break 1.4 %[3]
Hardness (scale-specific)Shore A / Shore D / RockwellRockwell R102 (and M95) on extruded unfilled PP stock (ASTM D785); no figure is published for a carbon-fibre PP filament[19]Rockwell 105 (and R124) on extruded unfilled PPS stock (ASTM D785); no figure is published for a fibre-filled PPS filament[20]
Creep resistance / sustained load1–5Not documentedExcellent — 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[20][21][3]
Fatigue / repeated-flex resistance1–5Good[22]Not documented
Elasticity / flexibility1–5Slightly flexible in thin sections[1]Rigid[3]

Thermal Properties
HDT at 0.45 MPa°C158 (ISO 75, 0.45 MPa) — far above unfilled PP and above most engineering filaments[1]252.5 (PPS-CF10) and 236.3 (PPS-GF20), printed, ISO 75 at 0.45 MPa[3][4]
HDT at 1.8 MPa°C115 (ISO 75, 1.8 MPa)[1]133 (PPS-CF10) and 125.8 (PPS-GF20), printed, ISO 75 at 1.8 MPa[3][4]

Continuous service temperature°CNot documented170 long-term service on extruded PPS stock, converted from 338 °F; no figure published for the carbon-filled grade[20]
Environment & Chemical
Chemical resistanceExcellent against acids, alkalis and most solvents[15]Outstanding — PPS resists essentially all solvents below 200 °C[18]
Water / humidity resistance in service1–5Excellent — essentially unaffected[1]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. Inferred: no polyolefin was among the nine filaments in the Azimi chamber study, so this is a family-level judgement rather than a measurement[23]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[23]
Ventilation / filtration requirement1–5Open a window / occasional ventilation. Inferred — no polyolefin was measured in the chamber study[23]Ventilated room or enclosure recommended[23]
Dust & fibre handling hazardCarbon fibre is bound in the matrix; sanding dust should not be inhaled[1]Fibre is bound in the matrix; sanding dust should not be inhaled[3]
Solvents & Solubility
Soluble inNone at room temperature; chloroform dissolves the matrix at 60 °C and xylene at about 118 °C, leaving the fibre.[24][25]None — PPS does not dissolve in any known solvent below 200 °C.[26][27]
Softened or crazed byXylene, decalin, CCl4 and chlorobenzene are heavily absorbed at 20 °C; oleum, chlorosulphonic acid and bromine destroy it.[24]Nothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[27]
Solvent welding & smoothing agentNone — nothing softens PP at room temperature, so joints have to be welded thermally rather than chemically.[24]None — no solvent welds or smooths PPS.[26]

Material entries describe families or representative grades, not an interchangeable specification for every spool. Test methods, orientations and conditions may differ.
