Nozzle temperature°CNot documented230–260 (Extrudr FLEX HARD CF)[2]
Bed temperature°CNot documented50–90 (Extrudr FLEX HARD CF)[2]
Enclosure / chamber requirement1–5Enclosure required (passive) — Polymaker states its Fiberon PPS-CF10 needs no heated chamber, unlike the unfilled sulfones and PAEKs[1]Open frame is fine[2]
Bed surface & adhesion aidNot documentedPEI sheet or painter's tape; Polymaker warns TPU can over-stick and advises a glue stick as a release agent[9][10]
Maximum volumetric flow (mm³/s; see test conditions)mm³/sNot documented1.6–8 at the 20–100 mm/s Extrudr specifies on a 0.4 mm nozzle at 0.2 mm layer[2]
Overall printing difficulty1–5Expert / industrial hardware only[1]Advanced — enclosure, hardware upgrades, tuning; hardened nozzle needed[2]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[1]Hardened steel required — Extrudr marks FLEX HARD CF as needing a hardened nozzle where its unfilled FLEX grades do not[2]
Abrasiveness1–5Highly abrasive — standard CF composite[1]Highly abrasive — standard CF composite[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]High — jams from moisture, heat creep or particles; a flexible base plus chopped carbon fibre, which Prusa lists as a higher nozzle-clogging risk, and Extrudr requires a hardened nozzle[12][2][9]
Hotend requirementNot documentedNo special hot-end required, but a direct-drive extruder is (Simplify3D)[9]
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][3]Moderate[13]
Equilibrium moisture content at ~50 % RH%0.225 equilibrium (Fiberon PPS-CF10); 0.11 (PPS-GF20)[1][3]Not documented
Drying temperature & timeNot documented60 °C for 6 h (Extrudr FLEX HARD CF)[2]
Symptoms when wetNot documentedBubbling and popping at the nozzle, stringing and a rough surface[13]
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]Polymaker groups TPU with the highly hygroscopic materials; no dry-versus-conditioned figures are published[13]
Storage requirementNot documentedSealed with desiccant; often kept in a dryer during the print[13]
Mechanical Properties
Tensile strength (XY)MPa59.4 ± 1.3 (PPS-CF10) and 64.1 ± 2.1 (PPS-GF20) printed XY, ISO 527[1][3]Not documented
Young's modulusMPa5446.7 ± 149.0 (PPS-CF10) and 4552.0 ± 54.6 (PPS-GF20) printed XY, ISO 527[1][3]35 (Extrudr FLEX HARD CF, ISO 527-2/5A/500)[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][3]380 ultimate elongation (Extrudr FLEX HARD CF, ISO 527-2/5A/500), against 490 for the unfilled FLEX HARD[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][3]Not documented
Layer adhesion / Z tensileMPa32.0 ± 5.1 (PPS-CF10) and 22.9 ± 0.8 (PPS-GF20) printed Z, ISO 527[1][3]Not documented
Brittleness1–5Very brittle — cracks or shatters easily; elongation at break 1.4 %[1]Very ductile — bends far before failing[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]70 Shore D (Extrudr FLEX HARD CF, ISO 868), against 58 Shore D for the unfilled FLEX HARD[2]
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]Below average — no CF-grade creep test; the grade is 70 Shore D where a 95A TPU bar crept from 74.5 to 82.7 mm over 5 days at 1.25 kg[2][16]
Fatigue / repeated-flex resistance1–5Not documentedGood — 380 % ultimate elongation and a damping application set (Extrudr cites longboard wheels), below the unfilled grades[2]
Elasticity / flexibility1–5Rigid[1]Semi-flexible[2]
Z strength as % of XY%54 (PPS-CF10) and 36 (PPS-GF20), printed[1][3]Not documented

Continuous service temperature°C170 long-term service on extruded PPS stock, converted from 338 °F; no figure published for the carbon-filled grade[14]Not documented
Environment & Chemical
UV resistance1–5Not documentedGood — years with some colour shift; Polymaker lists UV exposure among the conditions TPU withstands[10]
Chemical resistanceOutstanding — PPS resists essentially all solvents below 200 °C[11]Withstands industrial solvents and UV exposure (Polymaker)[10]
Food contactNot documentedNot food safe without specific certification (Polymaker)[10]
Biodegradability / compostabilityNot documentedNot biodegradable[10]
RecyclabilityNot documentedNot accepted in household plastic collection[10]
Electrical & ESD propertiesSurface resistivity above 10¹² ohm — insulating (ANSI/ESD S11.11)[1][3]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[17]Low hazard — minimal VOC and particle emission; TPU was not among the nine filaments in the chamber study[17]
Ventilation / filtration requirement1–5Ventilated room or enclosure recommended[17]Open a window / occasional ventilation[17]
Dust & fibre handling hazardFibre is bound in the matrix; sanding dust should not be inhaled[1]Carbon fibre is bound in the matrix; sanding dust should not be inhaled[2]
Post-Processing
Sanding & machiningNot documentedDifficult to sand or smooth; Polymaker limits post-processing to trimming or tumbling[10]
Gluing & solvent weldingNot documentedCyanoacrylate bonds TPU; no common solvent welds it[10]
Vapour / chemical smoothingNot documentedNo practical vapour smoothing[10]
Support material pairingNot documentedPolymaker warns TPU supports are often very difficult to remove[10]
Dimensional accuracy & detailNot documentedTear strength 165 kN/m (Extrudr FLEX HARD CF, ISO 34-1B)[2]
Solvents & Solubility
Soluble inNone — PPS does not dissolve in any known solvent below 200 °C.[18][19]DMF, DMSO, NMP and THF dissolve the TPU matrix and leave the fibre; ketones are partial solvents. Laboratory reagents.[20]
Softened or crazed byNothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[19]Toluene and benzene swell it up to +50 % by weight at 23 °C; esters swell it severely; ethanol and IPA soften it.[20]
Solvent welding & smoothing agentNone — no solvent welds or smooths PPS.[18]None practical — the true solvents (DMF, THF, NMP) are laboratory reagents and leave the joint swollen and weak.[20]
