| Densityg/cm³ | 1.17–1.24 (Polymaker); 1.21 (Bambu Lab, ISO 1183)[1][2] | 1.29 (Fiberon PPS-CF10) and 1.36 (Fiberon PPS-GF20), ISO 1183[3][4] |
| Typical priceUSD/kg | Mainstream 1 kg spools cluster near 16[5][6] | 1 kg-equivalent spools span 93–174; the middle of the market is about 140[7][8][9][10] |
| Price range across brandsUSD/kg | 10–40 across brands; budget house brands 10–17, Sakata 3D HR-870 26, Polymaker and Fiberlogy 36–40[11][6][12][13][14] | 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[7][8][9][10] |
| Market availability1–5 | Stocked by most mainstream brands[11][5][6][12][13] | Available from several mainstream brands[7][8][9] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 0.75, 0.85, 1 and 1.1 kg spools[12][13][11] | 1.75 mm; 0.5 kg spools[7] |
| Typical applications | Functional parts and enclosures that need impact tolerance but not heat resistance[1][2] | Chemical and automotive parts needing PPS chemistry with structural stiffness[3] |
| Diameter tolerance± mm | ±0.03 (Bambu Lab)[15] | Not documented |
| Printing Parameters | ||
| Nozzle temperature°C | 190–230 (Polymaker); Bambu Lab Tough+ needs 220–250[1][2] | Not documented |
| Bed temperature°C | 25–60 (Polymaker); 35–65 (Bambu Lab Tough+)[1][2] | Not documented |
| Enclosure / chamber requirement1–5 | Open frame is fine[1][2] | Enclosure required (passive) — Polymaker states its Fiberon PPS-CF10 needs no heated chamber, unlike the unfilled sulfones and PAEKs[3] |
| Part cooling fan | Fan on[1][2] | Not documented |
| Bed surface & adhesion aid | Textured or smooth PEI; Bambu Lab recommends glue stick or liquid glue for Tough+[1][2] | Not documented |
| Warping tendency1–5 | None[1] | Not documented |
| Bed-adhesion difficulty1–5 | Sticks to anything[16] | Not documented |
| Stringing / oozing tendency1–5 | Slight — 1–3 mm retraction handles it[1][16] | Not documented |
| Overall printing difficulty1–5 | Easy — minor profile tuning; Tough+ wants a hotter nozzle than plain PLA[1][2] | Expert / industrial hardware only[3] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely[17] | Hardened steel required[3] |
| Abrasiveness1–5 | Non-abrasive[18][17] | Highly abrasive — standard CF composite[3] |
| Nozzle clog risk1–5 | Very low[17] | 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[19][20] |
| Heat-creep / jam sensitivity1–5 | Moderate — good heatbreak cooling needed; softens below 60 °C like plain PLA[21] | Not documented |
| Hotend requirement | No special hot-end required[16] | Not documented |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Low — 0.27 % saturated at 25 °C / 55 % RH[2] | Low (0.1–0.3 %) — 0.225 % equilibrium for Fiberon PPS-CF10 and 0.11 % for PPS-GF20[3][4] |
| Equilibrium moisture content at ~50 % RH% | 0.27 saturated at 25 °C / 55 % RH (Bambu Lab Tough+)[2] | 0.225 equilibrium (Fiberon PPS-CF10); 0.11 (PPS-GF20)[3][4] |
| Drying temperature & time | 55 °C for 6–8 h; 65–75 °C for 12 h on a Bambu Lab X1 heatbed[1][2] | Not documented |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing, rough surface and weak layers[22] | Not documented |
| Effect of moisture on strength | Polymaker rates PLA low-sensitivity and publishes no dry-versus-conditioned figures for the modified grades; the loss shows as poor layer adhesion rather than a strength number[22] | No dry-versus-conditioned figures are published; equilibrium uptake is 0.225 % and Polymaker specifies a 100 °C, 10 h dry[3] |
| Storage requirement | Sealed with desiccant below 20 % RH; shelf life at ambient is long[2][16] | Not documented |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 35–43 (printed XY, ISO 527); 53 on My Tech Fun 4×4 mm bars for Bambu Lab Tough[1][2][23][24] | 59.4 ± 1.3 (PPS-CF10) and 64.1 ± 2.1 (PPS-GF20) printed XY, ISO 527[3][4] |

| Hardness (scale-specific)Shore A / Shore D / Rockwell | 78.8 Shore D measured on printed bars (My Tech Fun), against 75.3 for the same maker's plain PLA[28] | Rockwell 105 (and R124) on extruded unfilled PPS stock (ASTM D785); no figure is published for a fibre-filled PPS filament[29] |
| Creep resistance / sustained load1–5 | Poor — 12 mm bar sagged to 20.2 mm over 5 days at 1.25 kg, the same as plain PLA[24][30] | 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[29][31][3] |
| Fatigue / repeated-flex resistance1–5 | Below average — impact modifiers raise absorbed energy 5–9×; plain PLA ran 38 000–49 000 cycles at 30 % of tensile strength[32][2][23] | Not documented |
| Elasticity / flexibility1–5 | Rigid[1] | Rigid[3] |
| Z strength as % of XY% | 60 (Bambu Lab Tough+) to 78 (PolyMax PLA), printed[1][2] | 54 (PPS-CF10) and 36 (PPS-GF20), printed[3][4] |

| Environment & Chemical | ||
| UV resistance1–5 | Degrades within weeks outdoors[21][35] | Not documented |
| Chemical resistance | Good against weak acids, oils and grease; poor against strong acids and alkalis[1][2] | Outstanding — PPS resists essentially all solvents below 200 °C[19] |
| Food contact | Base resin is food-contact grade, but printed layer grooves harbour bacteria; Prusa advises against food use[21] | Not documented |
| Biodegradability / compostability | Industrially compostable only — needs sustained 55 °C; not home compostable[36][21] | Not documented |
| Recyclability | Mechanically recyclable; not accepted in household plastic collection[36] | Not documented |
| Electrical & ESD properties | Not documented | Surface resistivity above 10¹² ohm — insulating (ANSI/ESD S11.11)[3][4] |
| Health & Safety | ||
| Fume toxicity1–5 | Low hazard — minimal VOC and particle emission[37] | 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[37] |
| Ventilation / filtration requirement1–5 | None needed in a normal room[37] | Ventilated room or enclosure recommended[37] |
| Dust & fibre handling hazard | Not documented | Fibre is bound in the matrix; sanding dust should not be inhaled[3] |
| Post-Processing | ||
| Sanding & machining | Wet sanding — dry sanding heats the surface by friction and smears it[35][21] | Not documented |
| Gluing & solvent welding | Cyanoacrylate for most joints; some grades partially dissolve and bond with acetone[21][38] | Not documented |
| Vapour / chemical smoothing | No practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[21] | Not documented |

| Solvents & Solubility | ||
| Soluble in | Chloroform: 10 % w/v in 2–4 h at 23 °C, every grade and morphology; THF and DMF only at 65 °C. Laboratory reagents.[39] | None — PPS does not dissolve in any known solvent below 200 °C.[40][41] |
| 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.[39][42] | Nothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[41] |
| Solvent welding & smoothing agent | Chloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[43][42] | None — no solvent welds or smooths PPS.[40] |
