Identity & Market
Base polymer / chemistryPolyethylene terephthalate glycol copolymer — PET with a glycol comonomer that suppresses crystallisation[1][2]Carbon-fibre reinforced PPS — Polymaker's Fiberon grade is nominally 10 wt%[3]
Densityg/cm³1.24–1.30 (ISO 1183)[1][2][4][5]1.29 (Fiberon PPS-CF10) and 1.36 (Fiberon PPS-GF20), ISO 1183[3][6]
Typical priceUSD/kg1 kg spools cluster near 20[7][8][9]1 kg-equivalent spools span 93–174; the middle of the market is about 140[8][10][11][12]
Price range across brandsUSD/kg12–70 across brands; IEMAI 12, ELEGOO 14, CHCKX 14, Bambu Lab 18–20, Hatchbox 26, Prusament 38, Prusament PETG V0 70[7][8][13][9][14][15]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][10][11][12]
Market availability1–5Ubiquitous, every brand and retailer[7][8][16][9]Available from several mainstream brands[8][10][11]
Spool sizes & diameters1.75 and 2.85 mm; 0.75, 0.8 and 1 kg spools plus spool-less refills[8][9]1.75 mm; 0.5 kg spools[8]
Typical applicationsFunctional parts, enclosures and outdoor fittings that need more toughness and heat tolerance than PLA[1][2]Chemical and automotive parts needing PPS chemistry with structural stiffness[3]
Diameter tolerance± mm±0.02 (Prusament)[1]Not documented
Printing Parameters
Nozzle temperature°C230–260 across brands; Prusament 250 ± 10, Polymaker 240–260[1][2][5]Not documented
Bed temperature°C60–90; Prusament 80 ± 10, Polymaker 60–70[1][5]Not documented
Enclosure / chamber requirement1–5Open frame is fine[5]Enclosure required (passive) — Polymaker states its Fiberon PPS-CF10 needs no heated chamber, unlike the unfilled sulfones and PAEKs[3]
Part cooling fanAround 50 %; Polymaker specifies 20–60 %, less than PLA to protect layer bonding[1][5]Not documented
Bed surface & adhesion aidTextured PEI, satin or powder-coated sheets. On smooth PEI a glue stick is used as a release agent, not an adhesive — PETG bonds to bare PEI hard enough to tear the sheet[1][5]Not documented
Maximum volumetric flow (mm³/s; see test conditions)mm³/s8–15 (PrusaSlicer guidance); My Tech Fun ran Bambu Lab PETG Basic at 13 mm³/s[17][18]Not documented
Warping tendency1–5Slight — corner lift on large flat parts[1][5]Not documented
Bed-adhesion difficulty1–5Needs the right surface or a thin adhesive — the problem is releasing the part, not sticking it[1]Not documented
Stringing / oozing tendency1–5Moderate — retraction tuning needed[1][5]Not documented
Overall printing difficulty1–5Easy — minor profile tuning[5]Expert / industrial hardware only[3]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[17]Hardened steel required[3]
Abrasiveness1–5Non-abrasive[5]Highly abrasive — standard CF composite[3]
Nozzle clog risk1–5Low — no special hot-end required and clogging is not among the listed drawbacks; Prusa lists no drybox and no hardened nozzle[19][20]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[21][22]
Heat-creep / jam sensitivity1–5Slightly sensitive[19]Not documented
Hotend requirementNo special hot-end required[19]Not documented
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate (0.3–0.8 %) — Bambu Lab reports 0.40 % saturated at 25 °C / 55 % RH; Prusa measures only 0.07 % in 24 h and 0.10 % in 7 days at the drier 22 % RH[1][23]Low (0.1–0.3 %) — 0.225 % equilibrium for Fiberon PPS-CF10 and 0.11 % for PPS-GF20[3][6]
Equilibrium moisture content at ~50 % RH%0.10 after 7 days at 24 °C / 22 % RH (Prusa Polymers); 0.40 saturated at 25 °C / 55 % RH (Bambu Lab)[1][23]0.225 equilibrium (Fiberon PPS-CF10); 0.11 (PPS-GF20)[3][6]
Drying temperature & time60–65 °C for 6–8 h[5][23]Not documented
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[1]Not documented
Effect of moisture on strengthPolymaker groups PETG with nylon, PVA and TPU as highly hygroscopic and shows a before-and-after-drying comparison; the loss appears as poor layer adhesion and weak, brittle layers rather than a published dry-versus-conditioned figure[24]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[24][25]Not documented

Elongation at break%5.2–9.3 at break (printed XY, ISO 527); Prusament 5.1 at yield[2][4][5][1]1.4 ± 0.1 (PPS-CF10) and 2.0 ± 0.2 (PPS-GF20) printed XY, ISO 527 — the lowest elongation in the dataset[3][6]

Flexural modulusMPa1068–2277 (printed XY, ISO 178)[1][2][4][5]Not documented

Brittleness1–5Moderate[1][2]Very brittle — cracks or shatters easily; elongation at break 1.4 %[3]
Hardness (scale-specific)Shore A / Shore D / Rockwell74 Shore D (Prusa Polymers method); measured on printed bars at 68.2 for Extrudr PETG, 72 for Fiberlogy PETG and 72.8 for Prusament PETG[1][26][27][28]Rockwell 105 (and R124) on extruded unfilled PPS stock (ASTM D785); no figure is published for a fibre-filled PPS filament[29]
Creep resistance / sustained load1–5Below average — a 12 mm bar sagged to 18.2 mm (Fiberlogy) and 19.4 mm (Bambu Lab Basic) over 5 days at 1.25 kg[26][18]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[29][30][3]
Fatigue / repeated-flex resistance1–5Moderate — 79 000–193 000 cycles at 30 % of tensile strength, about three times printed PLA (R = 0.2, 7 Hz)[31]Not documented

Flammability / UL 94Flammable; no UL 94 rating published for standard PETG, though flame-retardant V0 grades exist[34][25]Not documented
Environment & Chemical
UV resistance1–5Moderate — a season or two[1]Not documented
Chemical resistanceWithstands acids, alkalis, oils and UV exposure — Polymaker names outdoor use as a result[25]Outstanding — PPS resists essentially all solvents below 200 °C[21]
Water / humidity resistance in service1–5Good — minor absorption[1]Not documented
Food contactPET is the polymer of drinks bottles, but printed layer grooves harbour bacteria and no filament here carries a food-contact certification[25]Not documented
Biodegradability / compostabilityNot biodegradable[25]Not documented
RecyclabilityPET is widely recycled as bottle stock, but printed PETG waste is not accepted in household collection[25]Not documented
Electrical & ESD propertiesNot documentedSurface resistivity above 10¹² ohm — insulating (ANSI/ESD S11.11)[3][6]
Health & Safety
Fume toxicity1–5Moderate — measurable VOCs and UFPs, ventilation advised[35]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[35]
Ultrafine-particle emission rateparticles/min≈5 × 10⁹ median for the PET-based T-Glase filament in the same chamber study, against ≈1 × 10⁸ for PLA[35]Not documented
Ventilation / filtration requirement1–5Open a window / occasional ventilation[35]Ventilated room or enclosure recommended[35]
Dust & fibre handling hazardNot documentedFibre 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[19]Not documented
Painting & finishingPaint adheres poorly without abrasion and a primer[1]Not documented
Gluing & solvent weldingCyanoacrylate; no common solvent welds PETG cleanly[19]Not documented
Vapour / chemical smoothingNo practical vapour smoothing[1]Not documented
Support material pairingPrints its own supports; Polymaker rates PolyDissolve S1 for PETG[19]Not documented
Dimensional accuracy & detailStringing and blobbing are the usual accuracy limits, not shrinkage[1][5]Not documented
Solvents & Solubility
Soluble inNo common workshop solvent; 1,2-dichloroethane destroys it inside a week and dichloromethane — a carcinogen — dissolves the surface.[36][37]None — PPS does not dissolve in any known solvent below 200 °C.[38][39]
Softened or crazed byAcetone (+16 % weight over 1 year at 23 °C), ethyl acetate, toluene and DMF swell and soften it; methanol crazes it.[36]Nothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[39]
Solvent welding & smoothing agentDichloromethane brushed on is the only agent that smooths PETG — a controlled carcinogen, not workshop stock.[37]None — no solvent welds or smooths PPS.[38]
