Identity & Market
Base polymer / chemistryCarbon-fibre reinforced PPS — Polymaker's Fiberon grade is nominally 10 wt%[1]Polyvinylidene fluoride — a semi-crystalline fluoropolymer[2][3]
Densityg/cm³1.29 (Fiberon PPS-CF10) and 1.36 (Fiberon PPS-GF20), ISO 1183[1][4]1.71 (ISO 1183) — the densest unfilled filament in the dataset[2]
Typical priceUSD/kg1 kg-equivalent spools span 93–174; the middle of the market is about 140[5][6][7][8]1 kg-equivalent spools cluster near 251[9]
Price range across brandsUSD/kg93-174 across brands and formats; Polymaker Fiberon PPS-GF20 93 at 3 kg, IEMAI 3D CF-PPS 131 at 750 g, LEHVOSS Luvocom 3F PPS CF 9938 164 at 2.3 kg, Bambu Lab PPS-CF 174 at 750 g[5][6][7][8]251 at 3DXTech's 750 g pricing — the most expensive material in the whole dataset[9]

Typical applicationsChemical and automotive parts needing PPS chemistry with structural stiffness[1]Chemical-plant fittings, semiconductor handling and parts needing outstanding UV and chemical resistance[2]
Printing Parameters
Bed temperature°CNot documented70–110 (3DXTech FluorX)[2]
Enclosure / chamber requirement1–5Enclosure required (passive) — Polymaker states its Fiberon PPS-CF10 needs no heated chamber, unlike the unfilled sulfones and PAEKs[1]Enclosure required (passive)[2]
Warping tendency1–5Not documentedHigh — enclosure needed for reliable large parts[2]
Overall printing difficulty1–5Expert / industrial hardware only[1]Expert / industrial hardware only[2][3]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[1]Brass fine indefinitely for unfilled grades[2]
Abrasiveness1–5Highly abrasive — standard CF composite[1]Non-abrasive when unfilled[2]
Nozzle clog risk1–5High — 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[11][12]Low — 3DXTech lists no special nozzle concerns, no minimum layer height and states drying is not required[10]
Other hardware wearNot documentedHydrogen fluoride released on overheating is extremely corrosive and will attack hotend and enclosure metalwork as well as people[3]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Low (0.1–0.3 %) — 0.225 % equilibrium for Fiberon PPS-CF10 and 0.11 % for PPS-GF20[1][4]Negligible (<0.1 % EMC) — fluoropolymers are essentially non-hygroscopic[2]
Equilibrium moisture content at ~50 % RH%0.225 equilibrium (Fiberon PPS-CF10); 0.11 (PPS-GF20)[1][4]Not documented
Effect of moisture on strengthNo dry-versus-conditioned figures are published; equilibrium uptake is 0.225 % and Polymaker specifies a 100 °C, 10 h dry[1]Not applicable in practice — 3DXTech states drying is not required for PVDF, so there is no moisture-driven strength loss to measure[10]
Mechanical Properties
Tensile strength (XY)MPa59.4 ± 1.3 (PPS-CF10) and 64.1 ± 2.1 (PPS-GF20) printed XY, ISO 527[1][4]51 at break (printed XY, ISO 527)[2]
Young's modulusMPa5446.7 ± 149.0 (PPS-CF10) and 4552.0 ± 54.6 (PPS-GF20) printed XY, ISO 527[1][4]2450 (printed XY, ISO 527)[2]
Elongation at break%1.4 ± 0.1 (PPS-CF10) and 2.0 ± 0.2 (PPS-GF20) printed XY, ISO 527 — the lowest elongation in the dataset[1][4]25 at break (printed XY, ISO 527)[2]

Flexural modulusMPaNot documented1800 (printed XY, ISO 178)[2]
Charpy impact, notchedkJ/m²5.3 ± 0.2 printed XY for PPS-CF10 and 7.3 ± 0.2 for PPS-GF20, ISO 179 notched[1][4]Not documented
Other impact dataNot documentedIzod 133 J/m on extruded PVDF stock, converted from 2.49 ft-lb/in (ASTM D256)[13]
Layer adhesion / Z tensileMPa32.0 ± 5.1 (PPS-CF10) and 22.9 ± 0.8 (PPS-GF20) printed Z, ISO 527[1][4]Not documented
Brittleness1–5Very brittle — cracks or shatters easily; elongation at break 1.4 %[1]Tough — absorbs impact, yields before breaking[2]
Hardness (scale-specific)Shore A / Shore D / RockwellRockwell 105 (and R124) on extruded unfilled PPS stock (ASTM D785); no figure is published for a fibre-filled PPS filament[14]Rockwell M79 on extruded PVDF stock (ASTM D785)[13]
Creep resistance / sustained load1–5Excellent — 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[14][15][1]Not documented
Elasticity / flexibility1–5Rigid[1]Slightly flexible in thin sections[2]
Z strength as % of XY%54 (PPS-CF10) and 36 (PPS-GF20), printed[1][4]Not documented
Thermal Properties
HDT at 0.45 MPa°C252.5 (PPS-CF10) and 236.3 (PPS-GF20), printed, ISO 75 at 0.45 MPa[1][4]149 on extruded PVDF stock (ASTM D648 at 66 psi; converted from 300 °F)[13]

Thermal expansion (CTE)µm/m·KNot documented127.8 (extruded PVDF stock, ASTM D696; source states 7.1e-5 in/in/°F) — the highest thermal expansion of any engineering polymer in this dataset[13]
Flammability / UL 94Not documentedUL 94 V-0 on extruded PVDF stock; Ensinger lists inherent flame resistance[13]
Environment & Chemical
UV resistance1–5Not documentedExcellent — designed for permanent outdoor use; Ensinger lists good UV and weather resistance and high gamma radiation resistance for PVDF stock[2][13]
Chemical resistanceOutstanding — PPS resists essentially all solvents below 200 °C[11]Outstanding — resistant to most acids, solvents and oxidising agents, which is the reason to use it[2]
Water / humidity resistance in service1–5Not documentedExcellent — essentially unaffected[2]
Electrical & ESD propertiesSurface resistivity above 10¹² ohm — insulating (ANSI/ESD S11.11)[1][4]Not documented
Health & Safety
Fume toxicity1–5Moderate — 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[16]Very high — toxic decomposition products; local exhaust mandatory. Above 315 °C thermal decomposition yields hydrofluoric acid, hydrogen cyanide and carbon monoxide[3]
Hazardous species emittedNot documentedAbove 315 °C: hydrofluoric acid, hydrogen cyanide, phenols, carbon monoxide, carbon dioxide and dense smoke. HF is extremely corrosive, its skin burns may not be immediately visible or painful, and exposure can be fatal by skin absorption, inhalation or ingestion[3]
Ventilation / filtration requirement1–5Ventilated room or enclosure recommended[16]Local exhaust to outside / fume hood — the SDS states local exhaust is preferred[3]
Dust & fibre handling hazardFibre is bound in the matrix; sanding dust should not be inhaled[1]Molten polymer causes thermal burns and must not be pulled off the skin. If HF is detected during a decomposition event, cut the heat but keep the extraction running, ventilate, and clear non-essential people from the area[3]
Post-Processing
Dimensional accuracy & detailNot documentedThe processing window sits well below the 315 °C decomposition threshold, so nozzle temperature must be controlled rather than raised to chase flow[2][3]
Solvents & Solubility
Soluble inNone — PPS does not dissolve in any known solvent below 200 °C.[17][18]THF, MEK, DMF, DMAc, NMP, DMSO and trimethyl phosphate dissolve 5–10 wt% at ambient — Arkema's active solvents, all lab reagents.[19]
Softened or crazed byNothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[18]Acetone, MIBK, cyclohexanone, butyl acetate and glycol ethers swell it; alkalis above pH 12 attack the homopolymer.[19][20]
Solvent welding & smoothing agentNone — no solvent welds or smooths PPS.[17]None for the workshop — the active solvents (NMP, DMAc, DMF) are laboratory reagents used for casting membranes, not joints.[19]
