Identity & Market
Base polymer / chemistryPETG compounded with a conductive filler to bring surface resistivity into the static-dissipative range[1][2]Carbon-fibre reinforced PPS — Polymaker's Fiberon grade is nominally 10 wt%[3]
Densityg/cm³1.24 (Fiberon) and 1.28 (3DXTech), ISO 1183[1][2]1.29 (Fiberon PPS-CF10) and 1.36 (Fiberon PPS-GF20), ISO 1183[3][4]
Typical priceUSD/kg1 kg-equivalent spools span 66–140; the middle of the market is about 103[5][6]1 kg-equivalent spools span 93–174; the middle of the market is about 140[5][7][8][9]
Price range across brandsUSD/kg66–140 across brands; Fiberon PETG-ESD 66, 3DXSTAT ESD-PETG 140[5][6]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][7][8][9]
Market availability1–5Niche, a handful of specialist brands[5][6]Available from several mainstream brands[5][7][8]
Spool sizes & diameters1.75 mm; 0.5, 0.75, 1 and 3 kg spools[5][6]1.75 mm; 0.5 kg spools[5]
Typical applicationsElectronics fixtures, trays and jigs handled around static-sensitive components[1][2]Chemical and automotive parts needing PPS chemistry with structural stiffness[3]
Printing Parameters
Nozzle temperature°C250–290 (Fiberon)[1]Not documented
Bed temperature°C70–80 (Fiberon); 70 (3DXTech)[1][2]Not documented
Enclosure / chamber requirement1–5Open frame is fine — Fiberon specifies room-temperature chamber[1]Enclosure required (passive) — Polymaker states its Fiberon PPS-CF10 needs no heated chamber, unlike the unfilled sulfones and PAEKs[3]
Bed surface & adhesion aidTextured PEI, satin or powder-coated sheets; on smooth PEI a glue stick acts as a release agent[10][11]Not documented
Maximum volumetric flow (mm³/s; see test conditions)mm³/sFiberon rates the material to 500 mm/s, equivalent to 40 on a 0.4 mm nozzle at 0.2 mm layer — a machine-limited headline rather than a measured melt rate[1][12]Not documented
Bed-adhesion difficulty1–5Needs the right surface or a thin adhesive — the problem is releasing the part, not sticking it[10][11]Not documented
Stringing / oozing tendency1–5Moderate — retraction tuning needed; Polymaker names stringing as PETG's common quirk[11]Not documented
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile; resistivity depends on getting the nozzle temperature right[1]Expert / industrial hardware only[3]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[1]Hardened steel required[3]
Abrasiveness1–5Moderately abrasive — conductive carbon filler[1]Highly abrasive — standard CF composite[3]
Nozzle clog risk1–5Low — 3DXTech lists no special nozzle concerns and no minimum layer height for its ESD-PETG, only a 65 °C pre-dry[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][15]
Heat-creep / jam sensitivity1–5Slightly sensitive[16]Not documented
Hotend requirementNo special hot-end required[16]Not documented
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate (0.3–0.8 %) — the PETG matrix reaches 0.40 % saturated at 25 °C / 55 % RH and 3DXTech specifies a 65 °C, 4 h pre-dry[10][13]Low (0.1–0.3 %) — 0.225 % equilibrium for Fiberon PPS-CF10 and 0.11 % for PPS-GF20[3][4]
Equilibrium moisture content at ~50 % RH%0.41 equilibrium water absorption (Fiberon PETG-ESD)[1]0.225 equilibrium (Fiberon PPS-CF10); 0.11 (PPS-GF20)[3][4]
Drying temperature & time65 °C for 3 h (Fiberon)[1]Not documented
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[17]Not documented
Effect of moisture on strengthPolymaker groups PETG with nylon, PVA and TPU as highly hygroscopic; no dry-versus-conditioned strength figures are published for this grade and the loss 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[3]
Storage requirementSealed with desiccant; Polymaker groups PETG with the highly hygroscopic materials[17][11]Not documented
Mechanical Properties
Tensile strength (XY)MPa36.1 ± 0.9 printed XY, ISO 527 (Fiberon); 3DXTech quotes 50 at break[1][2]59.4 ± 1.3 (PPS-CF10) and 64.1 ± 2.1 (PPS-GF20) printed XY, ISO 527[3][4]
Young's modulusMPa1983 ± 75 printed XY, ISO 527 (Fiberon)[1]5446.7 ± 149.0 (PPS-CF10) and 4552.0 ± 54.6 (PPS-GF20) printed XY, ISO 527[3][4]
Elongation at break%7.3 ± 0.7 printed XY, ISO 527 (Fiberon); 3DXTech quotes 13 at break[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[3][4]
Flexural strengthMPa54.0 ± 2.5 printed XY, ISO 178 (Fiberon)[1]Not documented
Flexural modulusMPa1651 ± 141 printed XY, ISO 178 (Fiberon)[1]Not documented

Other impact dataCharpy unnotched 29.3 ± 2.2 printed XY (Fiberon, ISO 179)[1]Not documented
Layer adhesion / Z tensileMPa20.7 ± 0.6 printed Z, ISO 527 (Fiberon)[1]32.0 ± 5.1 (PPS-CF10) and 22.9 ± 0.8 (PPS-GF20) printed Z, ISO 527[3][4]
Brittleness1–5Moderate[1]Very brittle — cracks or shatters easily; elongation at break 1.4 %[3]
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 load1–5Below average — no ESD-grade creep test; unfilled PETG sagged from 12 to 17.1–20.4 mm over 5 days at 1.25 kg[19][20][21][22]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][23][3]
Fatigue / repeated-flex resistance1–5Moderate — no ESD-grade S-N curve; unfilled printed PETG ran 79 000–193 000 cycles at 30 % of tensile strength[24]Not documented
Elasticity / flexibility1–5Slightly flexible in thin sections[1]Rigid[3]
Z strength as % of XY%57 (Fiberon, printed Z against XY tensile)[1]54 (PPS-CF10) and 36 (PPS-GF20), printed[3][4]

Flammability / UL 94Flammable; no UL 94 rating published for standard grades[25]Not documented
Environment & Chemical
Chemical resistanceWithstands acids, alkalis, oils and UV exposure[11]Outstanding — PPS resists essentially all solvents below 200 °C[14]
Food contactNot certified for food contact as filament[11]Not documented
Biodegradability / compostabilityNot biodegradable[11]Not documented
RecyclabilityNot accepted in household plastic collection[11]Not documented
Electrical & ESD propertiesSurface resistivity falls with nozzle temperature: 7.0×10⁶–1.6×10⁷ ohm at 250 °C, 3.2×10⁵–4.7×10⁵ at 270 °C and below 1×10⁴ at 290 °C (Fiberon); 3DXTech quotes 10⁷–10⁹ ohm/sq[1][2]Surface resistivity above 10¹² ohm — insulating (ANSI/ESD S11.11)[3][4]
Health & Safety
Fume toxicity1–5Moderate — measurable VOCs and UFPs, ventilation advised[26]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[26]
Ventilation / filtration requirement1–5Open a window / occasional ventilation[26]Ventilated room or enclosure recommended[26]
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[3]
Post-Processing
Sanding & machiningSands poorly — the material is tough and gums rather than powders[16]Not documented
Gluing & solvent weldingCyanoacrylate; no common solvent welds PETG cleanly[16]Not documented
Vapour / chemical smoothingNo practical vapour smoothing[16]Not documented
Support material pairingPrints its own supports; Polymaker rates PolyDissolve S1 for PETG[16]Not documented
Dimensional accuracy & detailNozzle temperature has to be held steady — it moves surface resistivity by three orders of magnitude[1]Not documented
Solvents & Solubility
Soluble inNo common workshop solvent; 1,2-dichloroethane destroys it inside a week and dichloromethane — a carcinogen — dissolves the surface.[27][28]None — PPS does not dissolve in any known solvent below 200 °C.[29][30]
Softened or crazed byAcetone (+16 % weight over 1 year at 23 °C), ethyl acetate, toluene and DMF swell and soften it; methanol crazes it.[27]Nothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[30]
Solvent welding & smoothing agentDichloromethane brushed on is the only agent that smooths PETG — a controlled carcinogen, not workshop stock.[28]None — no solvent welds or smooths PPS.[29]
