Identity & Market
Base polymer / chemistryA carbon-filled compound conductive by volume rather than merely dissipative; Proto-pasta's is PLA-based, Recreus's and NinjaTek's are TPU, and add:north's Koltron G1 does not state its base polymer[1][2][3][4]Carbon-fibre reinforced PPS — Polymaker's Fiberon grade is nominally 10 wt%[5]
Densityg/cm³Not documented1.29 (Fiberon PPS-CF10) and 1.36 (Fiberon PPS-GF20), ISO 1183[5][6]
Typical priceUSD/kg1 kg-equivalent spools span 90–181 for the carbon-filled grades; add:north's Koltron G1 sits far above at 796 because it is sold only in 100 and 250 g coils[7][8][9]1 kg-equivalent spools span 93–174; the middle of the market is about 140[10][11][12][13]
Price range across brandsUSD/kg90–796 across brands; Proto-pasta conductive PLA 90 at 1 kg, Recreus Conductive Filaflex 160 at 500 g, NinjaTek Eel 181 at 1 kg, add:north Koltron G1 796 at 250 g[7][2][8][9]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[10][11][12][13]
Market availability1–5Niche, a handful of specialist brands[7][2]Available from several mainstream brands[10][11][12]
Spool sizes & diameters1.75 and 2.85 mm; 0.05, 0.1, 0.25, 0.5, 1 and 2 kg spools[7][2][8][9]1.75 mm; 0.5 kg spools[10]
Typical applicationsCapacitive touch surfaces, low-current traces, EMI shielding and static-safe fixtures[1]Chemical and automotive parts needing PPS chemistry with structural stiffness[5]
Printing Parameters
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[5]
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile[1]Expert / industrial hardware only[5]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass acceptable; hardened steel for volume work[1]Hardened steel required[5]
Abrasiveness1–5Moderately abrasive — conductive carbon filler[1]Highly abrasive — standard CF composite[5]
Nozzle clog risk1–5Low — Proto-pasta states the carbon-filled grade prints on standard PLA settings with no special nozzle required[1]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][15]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Not documentedLow (0.1–0.3 %) — 0.225 % equilibrium for Fiberon PPS-CF10 and 0.11 % for PPS-GF20[5][6]
Equilibrium moisture content at ~50 % RH%Not documented0.225 equilibrium (Fiberon PPS-CF10); 0.11 (PPS-GF20)[5][6]
Effect of moisture on strengthPolymaker rates PLA low-sensitivity and publishes no dry-versus-conditioned figures; absorbed water flashes to steam and shows as bubbling and poor layer adhesion[16]No dry-versus-conditioned figures are published; equilibrium uptake is 0.225 % and Polymaker specifies a 100 °C, 10 h dry[5]
Mechanical Properties
Tensile strength (XY)MPaNot documented59.4 ± 1.3 (PPS-CF10) and 64.1 ± 2.1 (PPS-GF20) printed XY, ISO 527[5][6]
Young's modulusMPaNot documented5446.7 ± 149.0 (PPS-CF10) and 4552.0 ± 54.6 (PPS-GF20) printed XY, ISO 527[5][6]
Elongation at break%Not documented1.4 ± 0.1 (PPS-CF10) and 2.0 ± 0.2 (PPS-GF20) printed XY, ISO 527 — the lowest elongation in the dataset[5][6]
Charpy impact, notchedkJ/m²Not documented5.3 ± 0.2 printed XY for PPS-CF10 and 7.3 ± 0.2 for PPS-GF20, ISO 179 notched[5][6]
Layer adhesion / Z tensileMPaNot documented32.0 ± 5.1 (PPS-CF10) and 22.9 ± 0.8 (PPS-GF20) printed Z, ISO 527[5][6]
Brittleness1–5Brittle — snaps with little warning; carbon-black loading at conductive levels embrittles PLA[1]Very brittle — cracks or shatters easily; elongation at break 1.4 %[5]
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[17]
Creep resistance / sustained load1–5Not documentedExcellent — 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[17][18][5]
Elasticity / flexibility1–5Rigid[1]Rigid[5]
Z strength as % of XY%Not documented54 (PPS-CF10) and 36 (PPS-GF20), printed[5][6]
Thermal Properties
HDT at 0.45 MPa°CNot documented252.5 (PPS-CF10) and 236.3 (PPS-GF20), printed, ISO 75 at 0.45 MPa[5][6]
HDT at 1.8 MPa°CNot documented133 (PPS-CF10) and 125.8 (PPS-GF20), printed, ISO 75 at 1.8 MPa[5][6]
Glass transition (Tg)°CNot documented97.7 (PPS-CF10) and 95.0 (PPS-GF20), DSC[5][6]
Melting point / Vicat°CNot documented279.7 (PPS-CF10) and 279.6 (PPS-GF20) melting, DSC; Vicat 267.5 and 272.5 (ISO 306)[5][6]
Continuous service temperature°CNot documented170 long-term service on extruded PPS stock, converted from 338 °F; no figure published for the carbon-filled grade[17]
Environment & Chemical
Chemical resistanceNot documentedOutstanding — PPS resists essentially all solvents below 200 °C[14]
Electrical & ESD propertiesConductive rather than dissipative — Proto-pasta sells the grade as electrically conductive composite PLA[1]Surface resistivity above 10¹² ohm — insulating (ANSI/ESD S11.11)[5][6]
Health & Safety
Fume toxicity1–5Low hazard — minimal VOC and particle emission; none of these materials was in the chamber study[19]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[19]
Ventilation / filtration requirement1–5Open a window / occasional ventilation[19]Ventilated room or enclosure recommended[19]
Dust & fibre handling hazardConductive carbon filler is bound in the matrix; avoid inhaling sanding dust[1]Fibre is bound in the matrix; sanding dust should not be inhaled[5]
Solvents & Solubility
Soluble inChloroform dissolves PLA-based grades, leaving the carbon black; TPU-based grades need DMF, NMP or THF. Laboratory reagents.[20][21]None — PPS does not dissolve in any known solvent below 200 °C.[22][23]
Softened or crazed byAcetone and ethyl acetate plasticise a PLA-based grade; a TPU-based grade swells in toluene, esters and alcohols.[20][21]Nothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[23]
Solvent welding & smoothing agentNone — neither PLA nor TPU has a workshop-safe welding or smoothing solvent.[20][21]None — no solvent welds or smooths PPS.[22]

Material entries describe families or representative grades, not an interchangeable specification for every spool. Test methods, orientations and conditions may differ. Unknown values are marked “Not documented”. Prices and source dates remain historical snapshots; check the linked guide for product details. Differences highlight text, not a universal winner.
