| Typical applications | Concept models, functional prototypes, low-wear toys, jigs used at room temperature[22] | Chemical and automotive parts needing PPS chemistry with structural stiffness[3] |
| Diameter tolerance± mm | ±0.02 (Prusament) to ±0.03 (Bambu Lab, Prusa Research standard)[1][6][23] | Not documented |
| Printing Parameters | ||
| Nozzle temperature°C | 190–230; Prusament specifies 210 ± 10[1][4][2] | Not documented |
| Bed temperature°C | 25–60; Prusament 40–60, Bambu Lab 35–45[1][4][2] | Not documented |
| Enclosure / chamber requirement1–5 | Open frame is fine[4][17] | Enclosure required (passive) — Polymaker states its Fiberon PPS-CF10 needs no heated chamber, unlike the unfilled sulfones and PAEKs[3] |
| Part cooling fan | 100 % from the second layer; reduce on the first one or two layers for bed adhesion[1][18] | Not documented |
| Bed surface & adhesion aid | Smooth or textured PEI, glass or painter's tape; glue stick only where release is a problem[4][24][18] | Not documented |

| Warping tendency1–5 | None[26][17] | Not documented |
| Bed-adhesion difficulty1–5 | Sticks to anything — glue only needed on smooth PEI[4][2][18] | Not documented |
| Stringing / oozing tendency1–5 | Slight — 1–3 mm retraction handles it; oozing rises with nozzle temperature[4][18][27] | Not documented |
| Overall printing difficulty1–5 | Beginner — prints on any machine out of the box[17][18] | Expert / industrial hardware only[3] |
| Extruder requirement | Any extruder; Bowden and direct drive both fine, no hardware upgrades[17] | Not documented |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely[17] | Hardened steel required[3] |
| Abrasiveness1–5 | Non-abrasive[26][17] | Highly abrasive — standard CF composite[3] |
| Nozzle clog risk1–5 | Very low[17][18] | 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[28][29] |
| Heat-creep / jam sensitivity1–5 | Moderate — good heatbreak cooling needed; softens below 60 °C so it deforms in a warm cold zone[24][30] | Not documented |
| Hotend requirement | Any standard hotend; PTFE-lined is fine at PLA temperatures[17] | Not documented |
| Other hardware wear | None — brass nozzles and standard drive gears are unaffected[26][17] | Not documented |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Moderate — 0.40–0.51 % saturated at 23–25 °C and 55–70 % RH[2][4][31] | Low (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% | 0.43 saturated at 25 °C / 55 % RH (Bambu Lab); 0.51 equilibrium (Polymaker)[2][4] | 0.225 equilibrium (Fiberon PPS-CF10); 0.11 (PPS-GF20)[3][5] |
| Drying temperature & time | 50–55 °C for 6–8 h in a forced-air dryer; 45 °C for 12 h in the Bambu Lab AMS HT[4][2][30] | Not documented |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing, rough surface and weak layers[32] | Not documented |
| Effect of moisture on strength | Polymaker rates PLA low-sensitivity — it absorbs moisture slowly and the loss shows as poor layer adhesion and brittle layers rather than a published strength figure[32] | 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][18] | Not documented |
| Mechanical Properties | ||

| Creep resistance / sustained load1–5 | Poor — deforms under load at room temperature; 12 mm bar sagged to 20.3 mm over 5 days at 1.25 kg[38][39] | 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[37][40][3] |
| Fatigue / repeated-flex resistance1–5 | Poor — 38 000–49 000 cycles at 30 % of tensile strength, against 79 000–193 000 for PETG (printed, R = 0.2, 7 Hz)[41][24] | Not documented |

| Continuous service temperature°C | 50–55 — loaded bars begin to move at this temperature[26][34] | 170 long-term service on extruded PPS stock, converted from 338 °F; no figure published for the carbon-filled grade[37] |
| Annealing response | Bambu Lab conditions specimens at 55 °C for 8 h; annealing at 50–60 °C for 6–12 h raises crystallinity but can warp parts[2][42] | Not documented |
| Thermal expansion (CTE)µm/m·K | 96 ± 5 at 0° and 99 ± 5 at 90° raster (printed PLA, fibre Bragg grating, 25–50 °C)[43] | Not documented |

| Environment & Chemical | ||
| UV resistance1–5 | Degrades within weeks outdoors[24][22] | Not documented |
| Outdoor durability | Not suitable for long-term outdoor use — UV embrittlement plus softening above 55 °C in direct sun[22][24] | Not documented |
| Chemical resistance | Good against weak acids, oils and grease; poor against strong acids and alkalis; dissolved by chloroform, THF and hot benzene[4][24] | Outstanding — PPS resists essentially all solvents below 200 °C[28] |
| Water / humidity resistance in service1–5 | Good — insoluble in water, absorbs 0.4–0.5 % at equilibrium[2][44] | Not documented |
| Food contact | Base resin is food-contact grade and EN 71-3 certified by some brands, but printed layer grooves harbour bacteria; Prusa advises against food use[24][44] | Not documented |
| Biodegradability / compostability | Industrially compostable only — needs sustained 55 °C and specific microbial conditions; not home compostable[44][24][2] | Not documented |
| Recyclability | Mechanically recyclable; not accepted in household plastic collection, so brand take-back schemes are the practical route[44] | Not documented |
| Electrical & ESD properties | Not documented | Surface resistivity above 10¹² ohm — insulating (ANSI/ESD S11.11)[3][5] |
| Health & Safety | ||
| Fume toxicity1–5 | Low hazard — minimal VOC and particle emission[45] | 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[45] |
| VOC emission rateµg/min | 4–5 lactide, the dominant VOC (chamber study, three printers)[45] | Not documented |
| Ultrafine-particle emission rateparticles/min | ≈1 × 10⁸ median across three printers; only laywood ≈8 × 10⁷ and laybrick ≈6 × 10⁷ were lower[45] | Not documented |

| Ventilation / filtration requirement1–5 | None needed in a normal room[45] | Ventilated room or enclosure recommended[45] |
| 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[22][24] | Not documented |
| Gluing & solvent welding | Cyanoacrylate for most joints; some grades partially dissolve and bond with acetone, depending on additives and colour[24][23] | Not documented |
| Vapour / chemical smoothing | No practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[24] | Not documented |
| Support material pairing | PolySupport and PolyDissolve S1 (Polymaker); Support for PLA (Bambu Lab)[4][2] | Not documented |
| Dimensional accuracy & detail | Good — low shrinkage and features under 0.2 mm resolve; 55° overhangs and 30 mm bridges[26][2][18] | 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.[46] | None — PPS does not dissolve in any known solvent below 200 °C.[47][48] |
| 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.[46][49] | Nothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[48] |
| Solvent welding & smoothing agent | Chloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[50][49] | None — no solvent welds or smooths PPS.[47] |
