| Price range across brandsUSD/kg | 93-174 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] | 223-733 across brands; IEMAI 3D 223 at 1 kg, 3DXTech ThermaX PPSU 250 at 500 g, 3D4Makers 425 at 750 g, Kimya PPSU-S 733 at 500 g[9][10][7][11] |
| Market availability1–5 | Available from several mainstream brands[5][6][7] | Niche, a handful of specialist brands[9][10][7] |
| Spool sizes & diameters | 1.75 mm; 0.5 kg spools[5] | 1.75 and 2.85 mm; 200 g to 750 g spools[9][10][7] |
| Typical applications | Chemical and automotive parts needing PPS chemistry with structural stiffness[1] | Steam-sterilisable medical and dental tooling, and aircraft interior parts[2] |
| Printing Parameters | ||
| Bed temperature°C | Not documented | 130–150 (3DXTech)[2] |
| Enclosure / chamber requirement1–5 | Enclosure required (passive) — Polymaker states its Fiberon PPS-CF10 needs no heated chamber, unlike the unfilled sulfones and PAEKs[1] | Actively heated chamber required[12][13] |
| Warping tendency1–5 | Not documented | Severe — heated chamber needed[12] |
| Overall printing difficulty1–5 | Expert / industrial hardware only[1] | Expert / industrial hardware only[12][13] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Hardened steel required[1] | Brass fine indefinitely for unfilled grades, but brass softens near these nozzle temperatures — hardened or plated hot ends are the norm[12] |
| Abrasiveness1–5 | Highly abrasive — standard CF composite[1] | Non-abrasive when unfilled[2] |
| Nozzle clog risk1–5 | 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[14][15] | Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a mandatory 120 °C pre-dry before every print[16] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Low (0.1–0.3 %) — 0.225 % equilibrium for Fiberon PPS-CF10 and 0.11 % for PPS-GF20[1][3] | Not documented |
| Equilibrium moisture content at ~50 % RH% | 0.225 equilibrium (Fiberon PPS-CF10); 0.11 (PPS-GF20)[1][3] | 0.37 in 24 h and 1.1 at saturation on extruded stock (ASTM D570)[17] |
| Effect of moisture on strength | No dry-versus-conditioned figures are published; equilibrium uptake is 0.225 % and Polymaker specifies a 100 °C, 10 h dry[1] | No dry-versus-conditioned figures are published; 3DXTech mandates a 120 °C, 4 h pre-dry before every print because trapped water flashes to steam at these nozzle temperatures[16] |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 59.4 ± 1.3 (PPS-CF10) and 64.1 ± 2.1 (PPS-GF20) printed XY, ISO 527[1][3] | 55 (printed XY, ISO 527, 3DXTech) and 55 (printed on side long edge, ASTM D638, Stratasys PPSF); 79 at yield on extruded stock[2][4][17] |
| Young's modulusMPa | 5446.7 ± 149.0 (PPS-CF10) and 4552.0 ± 54.6 (PPS-GF20) printed XY, ISO 527[1][3] | 2100 (printed, ASTM D638, Stratasys PPSF) and 2310 (printed XY, ISO 527, 3DXTech); 2344 on extruded stock[2][4][17] |
| 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] | 3 (printed, ISO 527 and ASTM D638) against 60 on extruded stock — printing costs PPSU almost all of its ductility[2][4][17] |
| Flexural strengthMPa | Not documented | 110 (printed, ISO 178 and ASTM D790, 3DXTech and Stratasys PPSF agree); 91 on extruded stock[2][4][17] |
| Flexural modulusMPa | Not documented | 2200 (printed, ASTM D790, Stratasys PPSF) and 2215 (printed XY, ISO 178, 3DXTech)[2][4] |
| Charpy impact, notchedkJ/m² | 5.3 ± 0.2 printed XY for PPS-CF10 and 7.3 ± 0.2 for PPS-GF20, ISO 179 notched[1][3] | Not documented |
| Other impact data | Not documented | Izod notched 58.7 J/m and unnotched 165.5 J/m (printed, ASTM D256 Method A, Stratasys PPSF); 160 J/m notched on extruded stock[4][17] |
| Layer adhesion / Z tensileMPa | 32.0 ± 5.1 (PPS-CF10) and 22.9 ± 0.8 (PPS-GF20) printed Z, ISO 527[1][3] | Not documented |
| Brittleness1–5 | Very brittle — cracks or shatters easily; elongation at break 1.4 %[1] | Brittle — snaps with little warning[2] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Rockwell 105 (and R124) on extruded unfilled PPS stock (ASTM D785); no figure is published for a fibre-filled PPS filament[18] | Rockwell M86 on printed PPSF (ASTM D785, Stratasys); M96 on extruded PPSU stock (and an unlabelled 123)[4][17] |
| Creep resistance / sustained load1–5 | 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[18][19][1] | Good. Printed PPSF holds 189 °C heat deflection at 1.8 MPa (ASTM D648) and extruded stock is rated 149 °C long-term service, but Ensinger does not claim the creep resistance it claims for PSU and PPS[4][17] |
| Elasticity / flexibility1–5 | Rigid[1] | Rigid[2] |
| Z strength as % of XY% | 54 (PPS-CF10) and 36 (PPS-GF20), printed[1][3] | Not documented |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | 252.5 (PPS-CF10) and 236.3 (PPS-GF20), printed, ISO 75 at 0.45 MPa[1][3] | 190 (printed XY, ISO 75 at 0.45 MPa, 3DXTech)[2] |
| HDT at 1.8 MPa°C | 133 (PPS-CF10) and 125.8 (PPS-GF20), printed, ISO 75 at 1.8 MPa[1][3] | 189 (printed, ASTM D648 at 264 psi, Stratasys PPSF); 207 on extruded stock, converted from 405 °F[4][17] |
| Glass transition (Tg)°C | 97.7 (PPS-CF10) and 95.0 (PPS-GF20), DSC[1][3] | 230 (DSC) — the highest glass transition in the dataset[2] |
| Melting point / Vicat°C | 279.7 (PPS-CF10) and 279.6 (PPS-GF20) melting, DSC; Vicat 267.5 and 272.5 (ISO 306)[1][3] | Not documented |
| Continuous service temperature°C | 170 long-term service on extruded PPS stock, converted from 338 °F; no figure published for the carbon-filled grade[18] | 149 long-term service on extruded PPSU stock, converted from 300 °F[17] |
| Thermal expansion (CTE)µm/m·K | Not documented | 55.0 (printed PPSF, ASTM D696; source states 5.5e-5 mm/mm/°C) and 55.8 on extruded stock (ASTM D696, from 3.1e-5 in/in/°F)[4][17] |
| Flammability / UL 94 | Not documented | UL 94 V-0 at 1.5 mm, rated on the base resin[2] |
| Environment & Chemical | ||
| Chemical resistance | Outstanding — PPS resists essentially all solvents below 200 °C[14] | Withstands repeated steam autoclaving, the usual reason to choose PPSU over PSU; Stratasys also lists PPSF as passing 24 h stress-crack exposure to antifreeze, petrol, motor oil, power-steering, transmission and washer fluid at 23 °C and 100 °C[2][4] |
| Electrical & ESD properties | Surface resistivity above 10¹² ohm — insulating (ANSI/ESD S11.11)[1][3] | Volume resistivity 5e13 to 1.5e14 ohm-cm and dielectric strength 80-290 V/mil on printed PPSF (ASTM D257, D149)[4] |
| Health & Safety | ||
| Fume toxicity1–5 | 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[20] | 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[20] |
| Ventilation / filtration requirement1–5 | Ventilated room or enclosure recommended[20] | Ventilated room or enclosure recommended[20] |
| Dust & fibre handling hazard | Fibre is bound in the matrix; sanding dust should not be inhaled[1] | Not documented |
| Solvents & Solubility | ||
| Soluble in | None — PPS does not dissolve in any known solvent below 200 °C.[21][22] | Dichloromethane dissolves it at 23 °C at every stress level; acetone solvates and softens unstressed PPSU (Solvay ESCR).[23] |
| Softened or crazed by | Nothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[22] | MEK ruptures stressed parts and toluene crazes them above 13.8 MPa; glass-filled grades survive where unfilled craze.[23] |
| Solvent welding & smoothing agent | None — no solvent welds or smooths PPS.[21] | Dichloromethane cements PPSU and NMP softens residual resin; both are laboratory reagents, not workshop stock.[23] |
