| Identity & Market | ||
| Base polymer / chemistry | PLA filled with chopped glass fibre — 12 wt% (Polymaker HT-PLA-GF), 15–20 wt% (eSUN PLA-GF). Bambu Lab PLA Galaxy uses glass microspheres, not fibre, and is not equivalent[1][2][3] | Carbon-fibre reinforced PPS — Polymaker's Fiberon grade is nominally 10 wt%[4] |
| Densityg/cm³ | 1.31 (eSUN) to 1.337 (Polymaker), ISO 1183 / GB/T 1033[1][2] | 1.29 (Fiberon PPS-CF10) and 1.36 (Fiberon PPS-GF20), ISO 1183[4][5] |
| Typical priceUSD/kg | 1 kg spools cluster near 30[6][7] | 1 kg-equivalent spools span 93–174; the middle of the market is about 140[8][9][10][11] |
| Price range across brandsUSD/kg | 30–60 across brands; Polymaker 30, Proto-pasta 60[6][7] | 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[8][9][10][11] |
| Market availability1–5 | Niche, a handful of specialist brands[6][7][2] | Available from several mainstream brands[8][9][10] |
| Spool sizes & diameters | 1.75 mm; 0.5 and 1 kg spools[7][8] | 1.75 mm; 0.5 kg spools[8] |
| Typical applications | Stiff brackets and fixtures; the Polymaker grade is aimed at parts annealed for heat resistance[1] | Chemical and automotive parts needing PPS chemistry with structural stiffness[4] |
| Printing Parameters | ||
| Nozzle temperature°C | 210–230 (Polymaker HT-PLA-GF)[1] | Not documented |
| Bed temperature°C | 25–60 (Polymaker HT-PLA-GF)[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[4] |
| Part cooling fan | Fan on — eSUN specifies 100 %[2] | Not documented |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | 28 at Polymaker's stated 350 mm/s on a 0.4 mm nozzle at 0.2 mm layer; eSUN prints its specimens at 60 mm/s[1][2][12] | Not documented |
| Shrinkage% | 0.05 in X-Y and Z, 0.10 diagonal (Polymaker HT-PLA-GF)[1] | Not documented |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile; hardened nozzle mandatory[1] | Expert / industrial hardware only[4] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Hardened steel required[1] | Hardened steel required[4] |
| Abrasiveness1–5 | Highly abrasive — standard GF composite[1] | Highly abrasive — standard CF composite[4] |
| Nozzle clog risk1–5 | Moderate — needs dry filament and a clean nozzle; Prusa lists higher risk of nozzle clogging for glass-filled composites[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][13] |
| Hotend requirement | Hardened steel or ruby nozzle; Polymaker's own slicer preset sets a minimum nozzle hardness of 40 HRC[1] | Not documented |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Moderate — the PLA matrix takes up 0.40–0.51 % saturated; no glass-filled grade publishes its own figure[15][16] | Low (0.1–0.3 %) — 0.225 % equilibrium for Fiberon PPS-CF10 and 0.11 % for PPS-GF20[4][5] |
| Equilibrium moisture content at ~50 % RH% | Not documented | 0.225 equilibrium (Fiberon PPS-CF10); 0.11 (PPS-GF20)[4][5] |
| Drying temperature & time | 60 °C for 6 h (Polymaker HT-PLA-GF)[1] | Not documented |
| 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[17] | No dry-versus-conditioned figures are published; equilibrium uptake is 0.225 % and Polymaker specifies a 100 °C, 10 h dry[4] |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 50.1 as printed and 50.2 annealed, printed XY, ISO 527 (Polymaker); eSUN quotes 59.3 by GB/T 1040[1][2] | 59.4 ± 1.3 (PPS-CF10) and 64.1 ± 2.1 (PPS-GF20) printed XY, ISO 527[4][5] |
| Young's modulusMPa | 3794 as printed, 4207 annealed, printed XY, ISO 527 (Polymaker)[1] | 5446.7 ± 149.0 (PPS-CF10) and 4552.0 ± 54.6 (PPS-GF20) printed XY, ISO 527[4][5] |
| Elongation at break% | 2.77 as printed, 2.3 annealed, printed XY, ISO 527 (Polymaker); eSUN quotes 7.99[1][2] | 1.4 ± 0.1 (PPS-CF10) and 2.0 ± 0.2 (PPS-GF20) printed XY, ISO 527 — the lowest elongation in the dataset[4][5] |
| Flexural strengthMPa | 86.4 printed XY, ISO 178 (Polymaker)[1] | Not documented |
| Flexural modulusMPa | 3685 printed XY, ISO 178 (Polymaker); eSUN quotes 4415 flexural modulus by GB/T 9341[1][2] | Not documented |
| Charpy impact, notchedkJ/m² | 5.31 ± 0.46 as printed and 4.92 ± 0.50 annealed (printed XY, ISO 179, notched); Z 4.28 ± 0.18[1] | 5.3 ± 0.2 printed XY for PPS-CF10 and 7.3 ± 0.2 for PPS-GF20, ISO 179 notched[4][5] |
| Other impact data | Izod 10.16 kJ/m² (eSUN, GB/T 1843)[2] | Not documented |
| Layer adhesion / Z tensileMPa | 23.7 as printed, 22.5 annealed, printed Z, ISO 527 (Polymaker)[1] | 32.0 ± 5.1 (PPS-CF10) and 22.9 ± 0.8 (PPS-GF20) printed Z, ISO 527[4][5] |
| Brittleness1–5 | Very brittle — elongation at break 2.77 % in XY and 0.85 % in Z[1] | Very brittle — cracks or shatters easily; elongation at break 1.4 %[4] |
| 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[18] |
| Creep resistance / sustained load1–5 | Poor — no GF-grade creep test; plain printed PLA sagged from 12 to 16.2–21.8 mm over 5 days at 1.25 kg[19][20][21] | 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][22][4] |
| Fatigue / repeated-flex resistance1–5 | Poor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength and elongation at break falls to 2.77 % in XY and 0.85 % in Z[23][1] | Not documented |
| Elasticity / flexibility1–5 | Rigid[1] | Rigid[4] |
| Z strength as % of XY% | 47 as printed (23.7 Z against 50.1 XY), printed[1] | 54 (PPS-CF10) and 36 (PPS-GF20), printed[4][5] |

| 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] |
| Annealing response | Annealing lifts HDT at 0.45 MPa from 75.5 to 114.7 °C and modulus from 3794 to 4207 MPa[1] | Not documented |
| Environment & Chemical | ||
| UV resistance1–5 | Degrades within weeks outdoors[24] | Not documented |
| Chemical resistance | Not documented | Outstanding — PPS resists essentially all solvents below 200 °C[14] |
| Electrical & ESD properties | Not documented | Surface resistivity above 10¹² ohm — insulating (ANSI/ESD S11.11)[4][5] |
| Health & Safety | ||
| Fume toxicity1–5 | Low hazard — minimal VOC and particle emission[25] | 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[25] |
| Ventilation / filtration requirement1–5 | None needed in a normal room[25] | Ventilated room or enclosure recommended[25] |
| Dust & fibre handling hazard | Glass fibre is bound in the matrix; avoid inhaling sanding dust[26] | Fibre is bound in the matrix; sanding dust should not be inhaled[4] |
| Post-Processing | ||
| Dimensional accuracy & detail | Near-zero shrinkage — 0.05 % in X-Y and Z (Polymaker)[1] | Not documented |
| Solvents & Solubility | ||
| Soluble in | Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[27] | None — PPS does not dissolve in any known solvent below 200 °C.[28][29] |
| Softened or crazed by | Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[27][30] | Nothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[29] |
| Solvent welding & smoothing agent | Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[31][30] | None — no solvent welds or smooths PPS.[28] |
