| Typical priceUSD/kg | 1 kg spools cluster near 71[4] | 1 kg-equivalent spools span 93–174; the middle of the market is about 140[5][6][7][8] |
| Price range across brandsUSD/kg | 71 — BASF Ultrafuse PC GF30 at igo3d is the only priced listing found; Owens Corning sells XSTRAND GF30-PC in 500 g and 1 kg[4][1] | 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] |
| Market availability1–5 | Niche, a handful of specialist brands — neither Polymaker's nor 3DXTech's polycarbonate range contains a glass-fibre grade, but BASF Forward AM and Owens Corning both sell one through European retail[4][1][5][9] | Available from several mainstream brands[5][6][7] |
| Spool sizes & diameters | 1.75 and 2.85 mm at +/- 0.05 mm; 500 g and 1 kg net spools[1] | 1.75 mm; 0.5 kg spools[5] |
| Typical applications | Functional prototyping for mechanical engineering, electronics and automotive[1] | Chemical and automotive parts needing PPS chemistry with structural stiffness[2] |
| Diameter tolerance± mm | +/- 0.05 (Owens Corning XSTRAND)[1] | Not documented |
| Printing Parameters | ||

| Bed temperature°C | 80-110 (Owens Corning XSTRAND GF30-PC)[1] | Not documented |
| Enclosure / chamber requirement1–5 | Enclosure required (passive) — as for unfilled PC[10][11] | Enclosure required (passive) — Polymaker states its Fiberon PPS-CF10 needs no heated chamber, unlike the unfilled sulfones and PAEKs[2] |

| Overall printing difficulty1–5 | Not documented | Expert / industrial hardware only[2] |
| Extruder requirement | Owens Corning specifies a nozzle above 0.4 mm and hardened steel nozzles and drive wheels[1] | Not documented |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Hardened steel required — Owens Corning states glass reinforcement shortens brass nozzle and drive-wheel life[1] | Hardened steel required[2] |
| Abrasiveness1–5 | Highly abrasive — 30 wt% glass fibre[1] | Highly abrasive — standard CF composite[2] |
| Nozzle clog risk1–5 | High — jams from moisture, heat creep or particles; PC already absorbs water from the air and Prusa lists glass-filled composites as a higher clogging risk[12][13] | 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][12] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Negligible (<0.1 % EMC) — Owens Corning measures below 0.1 % at 23 °C and 50 % RH (ISO 62)[1] | 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% | Below 0.1 at 23 °C and 50 % RH, and below 0.1 at saturation (ISO 62)[1] | 0.225 equilibrium (Fiberon PPS-CF10); 0.11 (PPS-GF20)[2][3] |
| Effect of moisture on strength | No dry-versus-conditioned figures are published. Polymaker calls PC highly hygroscopic; absorbed water flashes to steam and shows as bubbling and poor layer adhesion[15][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 | 65 at break (printed, ISO 527 at 1 mm/min)[1] | 59.4 ± 1.3 (PPS-CF10) and 64.1 ± 2.1 (PPS-GF20) printed XY, ISO 527[2][3] |
| Young's modulusMPa | 5400 (printed, ISO 527 at 1 mm/min)[1] | 5446.7 ± 149.0 (PPS-CF10) and 4552.0 ± 54.6 (PPS-GF20) printed XY, ISO 527[2][3] |
| Elongation at break% | 2.5 at break (printed, ISO 527 at 1 mm/min)[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 strengthMPa | 113 at yield (printed, ISO 178 at 2 mm/min)[1] | Not documented |
| Flexural modulusMPa | 5500 (printed, ISO 178 at 2 mm/min)[1] | Not documented |
| Charpy impact, notchedkJ/m² | Not documented | 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 | Brittle — snaps with little warning; 2.5 % elongation at break[1] | Very brittle — cracks or shatters easily; elongation at break 1.4 %[2] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Rockwell 70 (118) — the source does not name the scales and Shore D 79 on extruded unfilled PC stock (ASTM D785, D2240); no figure is published for a glass-fibre grade[17] | Rockwell 105 (and R124) on extruded unfilled PPS stock (ASTM D785); no figure is published for a fibre-filled PPS filament[18] |
| Creep resistance / sustained load1–5 | Excellent — holds load for years. Room-temperature tensile creep of moulded unfilled PC ran unbroken at 41 MPa until the test was stopped, and 30 wt% glass raises the tensile modulus from about 2.3 to 5.4 GPa[19][1] | 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][20][2] |
| 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] |
| HDT at 1.8 MPa°C | 137 (printed, ISO 75 Method A at 1.8 MPa)[1] | 133 (PPS-CF10) and 125.8 (PPS-GF20), printed, ISO 75 at 1.8 MPa[2][3] |
| Glass transition (Tg)°C | 145 (DSC, ISO 11357)[1] | 97.7 (PPS-CF10) and 95.0 (PPS-GF20), DSC[2][3] |
| Melting point / Vicat°C | 270 stated as melting point (ISO 11357) — unusual for an amorphous polymer, but this is the published figure[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[18] |
| Thermal expansion (CTE)µm/m·K | 26.2 in XY and 77.4 in Z (printed, ISO 11359-2) — a threefold anisotropy, and the lowest in-plane expansion of any polycarbonate here[1] | Not documented |
| Flammability / UL 94 | UL 94 V-0 verified (Owens Corning)[1] | Not documented |
| Environment & Chemical | ||
| UV resistance1–5 | Good — years with some colour shift. Owens Corning lists UV resistance as a product benefit but publishes no exposure data[1] | Not documented |
| Chemical resistance | Not documented | Outstanding — PPS resists essentially all solvents below 200 °C[14] |
| Water / humidity resistance in service1–5 | Excellent — essentially unaffected; below 0.1 % water at saturation (ISO 62)[1] | Not documented |
| Electrical & ESD properties | Electrically insulating (Owens Corning)[1] | Surface resistivity above 10¹² ohm — insulating (ANSI/ESD S11.11)[2][3] |
| Health & Safety | ||
| Fume toxicity1–5 | Moderate — measurable VOCs and UFPs, ventilation advised[21] | 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[21] |
| Ultrafine-particle emission rateparticles/min | ≈4 × 10¹⁰ median — the highest ultrafine-particle rate of the nine filaments in the chamber study, above every ABS tested[21] | Not documented |
| Ventilation / filtration requirement1–5 | Ventilated room or enclosure recommended[21][11] | Ventilated room or enclosure recommended[21] |
| Dust & fibre handling hazard | Owens Corning warns that the glass reinforcement is abrasive when melted and advises sufficient ventilation and avoiding extrusion fumes[1] | Fibre is bound in the matrix; sanding dust should not be inhaled[2] |
| Post-Processing | ||
| Dimensional accuracy & detail | High dimensional stability is the headline benefit; the 26.2 um/m*K in-plane CTE is a third of unfilled PC's[1] | Not documented |
| Solvents & Solubility | ||
| Soluble in | Dichloromethane and chloroform dissolve the matrix and leave the fibre; DMF and dioxane do the same (Covestro).[22] | None — PPS does not dissolve in any known solvent below 200 °C.[23][24] |
| Softened or crazed by | Methanol, butyl acetate, ether, 1 % NaOH and phthalate plasticisers stress-crack it; acetone, MEK and xylene swell it.[22] | Nothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[24] |
| Solvent welding & smoothing agent | Dichloromethane cement welds the resin, but the fibre keeps the joint from flowing closed. Controlled carcinogen.[25] | None — no solvent welds or smooths PPS.[23] |
