Identity & Market
Base polymer / chemistryPLA 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/cm³1.31 (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/kg1 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/kg30–60 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 availability1–5Niche, a handful of specialist brands[6][7][2]Available from several mainstream brands[8][9][10]
Spool sizes & diameters1.75 mm; 0.5 and 1 kg spools[7][8]1.75 mm; 0.5 kg spools[8]
Typical applicationsStiff 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°C210–230 (Polymaker HT-PLA-GF)[1]Not documented
Bed temperature°C25–60 (Polymaker HT-PLA-GF)[1]Not documented
Enclosure / chamber requirement1–5Open 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 fanFan on — eSUN specifies 100 %[2]Not documented
Maximum volumetric flow (mm³/s; see test conditions)mm³/s28 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 difficulty1–5Intermediate — dry filament and a tuned profile; hardened nozzle mandatory[1]Expert / industrial hardware only[4]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[1]Hardened steel required[4]
Abrasiveness1–5Highly abrasive — standard GF composite[1]Highly abrasive — standard CF composite[4]
Nozzle clog risk1–5Moderate — 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 requirementHardened 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)1–5Moderate — 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 documented0.225 equilibrium (Fiberon PPS-CF10); 0.11 (PPS-GF20)[4][5]
Drying temperature & time60 °C for 6 h (Polymaker HT-PLA-GF)[1]Not documented
Effect of moisture on strengthPolymaker 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)MPa50.1 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 modulusMPa3794 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 strengthMPa86.4 printed XY, ISO 178 (Polymaker)[1]Not documented

Other impact dataIzod 10.16 kJ/m² (eSUN, GB/T 1843)[2]Not documented
Layer adhesion / Z tensileMPa23.7 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]
Brittleness1–5Very 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 / RockwellNot documentedRockwell 105 (and R124) on extruded unfilled PPS stock (ASTM D785); no figure is published for a fibre-filled PPS filament[18]
Creep resistance / sustained load1–5Poor — 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 resistance1–5Poor — 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 / flexibility1–5Rigid[1]Rigid[4]

Continuous service temperature°CNot documented170 long-term service on extruded PPS stock, converted from 338 °F; no figure published for the carbon-filled grade[18]
Annealing responseAnnealing 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 resistance1–5Degrades within weeks outdoors[24]Not documented
Chemical resistanceNot documentedOutstanding — PPS resists essentially all solvents below 200 °C[14]
Electrical & ESD propertiesNot documentedSurface resistivity above 10¹² ohm — insulating (ANSI/ESD S11.11)[4][5]
Health & Safety
Fume toxicity1–5Low 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 requirement1–5None needed in a normal room[25]Ventilated room or enclosure recommended[25]
Dust & fibre handling hazardGlass 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 & detailNear-zero shrinkage — 0.05 % in X-Y and Z (Polymaker)[1]Not documented
Solvents & Solubility
Soluble inChloroform 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 byAcetone, 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 agentChloroform 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]
