Typical applicationsAutoclavable tooling, food-contact fixtures and parts that must hold load near 200 °C[2]Chemical and automotive parts needing PPS chemistry with structural stiffness[3]
Printing Parameters
Nozzle temperature°C410 ± 10 (Prusament) — the hottest nozzle in the dataset[2]Not documented
Bed temperature°C140–160 (Prusament); 130–140 (3DXTech)[2][1]Not documented
Enclosure / chamber requirement1–5Actively heated chamber required — Prusa specifies 90 °C[2]Enclosure required (passive) — Polymaker states its Fiberon PPS-CF10 needs no heated chamber, unlike the unfilled sulfones and PAEKs[3]
Recommended chamber temperature°C90 (Prusament)[2]Not documented
Bed surface & adhesion aidPA nylon sheet or powder-coated sheet with high-temperature glue (Prusament)[2]Not documented
Warping tendency1–5Severe — heated chamber needed[2]Not documented
Overall printing difficulty1–5Expert / industrial hardware only[2][14]Expert / industrial hardware only[3]
Extruder requirementA hot end rated to 420 °C, a heated chamber and a high-temperature bed; Prusa dries the filament at 150 °C for 6–8 h before printing[2]Not documented
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely for unfilled grades, but brass softens near these nozzle temperatures — hardened or plated hot ends are the norm[2]Hardened steel required[3]
Abrasiveness1–5Non-abrasive when unfilled[1]Highly abrasive — standard CF composite[3]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a mandatory 150 °C pre-dry before every print[15]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[16][17]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Not documentedLow (0.1–0.3 %) — 0.225 % equilibrium for Fiberon PPS-CF10 and 0.11 % for PPS-GF20[3][5]
Equilibrium moisture content at ~50 % RH%0.4 in 24 h and 0.7 in 7 days at 24 °C and 22 % RH (Prusament)[2]0.225 equilibrium (Fiberon PPS-CF10); 0.11 (PPS-GF20)[3][5]
Drying temperature & time150 °C for 6–8 h (Prusament) — the hottest drying schedule in the dataset[2]Not documented
Effect of moisture on strengthNo dry-versus-conditioned figures are published; 3DXTech mandates a 150 °C, 4 h pre-dry before every print because trapped water flashes to steam at these nozzle temperatures[15]No dry-versus-conditioned figures are published; equilibrium uptake is 0.225 % and Polymaker specifies a 100 °C, 10 h dry[3]

Dust & fibre handling hazardNot documentedFibre is bound in the matrix; sanding dust should not be inhaled[3]
Solvents & Solubility
Soluble inChlorinated hydrocarbons — dichloromethane and chloroform — are solvents for polyetherimide. Laboratory reagents.[22][23]None — PPS does not dissolve in any known solvent below 200 °C.[24][23]
Softened or crazed byAcetone, MEK, benzene, toluene and butyl acetate craze or stress-crack it; alcohols, fuels and dilute acids do not.[23][22]Nothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[23]
Solvent welding & smoothing agentDichloromethane is the only welding route, and it is a controlled carcinogen rather than a workshop material.[22][23]None — no solvent welds or smooths PPS.[24]
