| Price range across brandsUSD/kg | Not documented | 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[4][5][6][7] |
| Market availability1–5 | Niche, a handful of specialist brands[1][8] | Available from several mainstream brands[4][5][6] |

| Typical applications | General-purpose printing where PLA's brittleness is the limiting factor[1] | Chemical and automotive parts needing PPS chemistry with structural stiffness[2] |
| Printing Parameters | ||
| Nozzle temperature°C | 195–220 (colorFabb)[1] | Not documented |
| Bed temperature°C | 50–60 (colorFabb)[1] | Not documented |
| Enclosure / chamber requirement1–5 | Open frame is fine[1] | Enclosure required (passive) — Polymaker states its Fiberon PPS-CF10 needs no heated chamber, unlike the unfilled sulfones and PAEKs[2] |
| Part cooling fan | 0–100 %; colorFabb states the blend runs on both heated and unheated beds[1][9] | Not documented |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | 3.2–8 at colorFabb's 40–100 mm/s, on a 0.4 mm nozzle at 0.2 mm layer[9][10] | Not documented |
| Overall printing difficulty1–5 | Beginner — prints on any machine out of the box[1] | Expert / industrial hardware only[2] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely[1] | Hardened steel required[2] |
| Abrasiveness1–5 | Non-abrasive[1] | Highly abrasive — standard CF composite[2] |
| Nozzle clog risk1–5 | Very low — unfilled PLA blend; Prusa lists no drybox and no hardened nozzle for PLA[11] | 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[12][13] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Moderate — the PLA matrix takes up 0.40–0.51 % saturated; colorFabb publishes no figure for the blend[14][15] | Low (0.1–0.3 %) — 0.225 % equilibrium for Fiberon PPS-CF10 and 0.11 % for PPS-GF20[2][3] |
| Equilibrium moisture content at ~50 % RH% | Not documented | 0.225 equilibrium (Fiberon PPS-CF10); 0.11 (PPS-GF20)[2][3] |
| Effect of moisture on strength | Polymaker rates PLA low-sensitivity and publishes no dry-versus-conditioned figures for this grade; absorbed water flashes to steam and shows as bubbling and poor layer adhesion[16] | No dry-versus-conditioned figures are published; equilibrium uptake is 0.225 % and Polymaker specifies a 100 °C, 10 h dry[2] |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 62–64 (ISO 527-1A, colorFabb; two grades quoted)[1] | 59.4 ± 1.3 (PPS-CF10) and 64.1 ± 2.1 (PPS-GF20) printed XY, ISO 527[2][3] |
| Young's modulusMPa | 2960–3070 (ISO 527-1A, colorFabb)[1] | 5446.7 ± 149.0 (PPS-CF10) and 4552.0 ± 54.6 (PPS-GF20) printed XY, ISO 527[2][3] |
| Elongation at break% | 4 and 11 (ISO 527-1A, colorFabb; two grades quoted)[1] | 1.4 ± 0.1 (PPS-CF10) and 2.0 ± 0.2 (PPS-GF20) printed XY, ISO 527 — the lowest elongation in the dataset[2][3] |
| Flexural modulusMPa | 2500–3300 flexural modulus (ISO 178, colorFabb)[1] | Not documented |
| Charpy impact, notchedkJ/m² | 2.8–3.7 (ISO 179, notched, colorFabb)[1] | 5.3 ± 0.2 printed XY for PPS-CF10 and 7.3 ± 0.2 for PPS-GF20, ISO 179 notched[2][3] |
| Layer adhesion / Z tensileMPa | Not documented | 32.0 ± 5.1 (PPS-CF10) and 22.9 ± 0.8 (PPS-GF20) printed Z, ISO 527[2][3] |
| Brittleness1–5 | Moderate — colorFabb positions the blend as tougher and less brittle than its generic PLA grades[1] | Very brittle — cracks or shatters easily; elongation at break 1.4 %[2] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Not documented | Rockwell 105 (and R124) on extruded unfilled PPS stock (ASTM D785); no figure is published for a fibre-filled PPS filament[17] |
| Creep resistance / sustained load1–5 | Poor — no PLA/PHA creep test; plain printed PLA sagged from 12 to 16.2–21.8 mm over 5 days at 1.25 kg[18][19][20] | 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[17][21][2] |
| Fatigue / repeated-flex resistance1–5 | Below average — no S-N curve for the blend; colorFabb positions it as tougher and less brittle than its generic PLA, which ran 38 000–49 000 cycles at 30 % of tensile strength[22][1] | Not documented |
| Elasticity / flexibility1–5 | Rigid[1] | Rigid[2] |
| Z strength as % of XY% | Not documented | 54 (PPS-CF10) and 36 (PPS-GF20), printed[2][3] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | Not documented | 252.5 (PPS-CF10) and 236.3 (PPS-GF20), printed, ISO 75 at 0.45 MPa[2][3] |

| Melting point / Vicat°C | Above 155 melting (ISO 3146-C)[1] | 279.7 (PPS-CF10) and 279.6 (PPS-GF20) melting, DSC; Vicat 267.5 and 272.5 (ISO 306)[2][3] |
| Continuous service temperature°C | Not documented | 170 long-term service on extruded PPS stock, converted from 338 °F; no figure published for the carbon-filled grade[17] |
| Environment & Chemical | ||
| UV resistance1–5 | Degrades within weeks outdoors[23] | Not documented |
| Chemical resistance | Not documented | Outstanding — PPS resists essentially all solvents below 200 °C[12] |
| Biodegradability / compostability | colorFabb states the PHA component is 100 % biodegradable[1] | Not documented |
| Electrical & ESD properties | Not documented | Surface resistivity above 10¹² ohm — insulating (ANSI/ESD S11.11)[2][3] |
| Health & Safety | ||
| Fume toxicity1–5 | Low hazard — minimal VOC and particle emission[24] | 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[24] |
| Ventilation / filtration requirement1–5 | None needed in a normal room[24] | Ventilated room or enclosure recommended[24] |
| Dust & fibre handling hazard | Not documented | Fibre is bound in the matrix; sanding dust should not be inhaled[2] |
| Solvents & Solubility | ||
| Soluble in | Chloroform dissolves the PLA phase (10 % w/v, 2–4 h at 23 °C); THF and DMF need 65 °C. Laboratory reagents.[25] | None — PPS does not dissolve in any known solvent below 200 °C.[26][27] |
| Softened or crazed by | Acetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[25][28] | Nothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[27] |
| Solvent welding & smoothing agent | Chloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[29][28] | None — no solvent welds or smooths PPS.[26] |
