Market availability1–5Niche, a handful of specialist brands[5][6]Available from several mainstream brands[6][9]
Spool sizes & diameters1.75 mm; 0.5, 0.75, 1 and 3 kg spools[5][6]1.75 mm; 0.65 kg spools[9][6]
Typical applicationsElectronics fixtures, trays and jigs handled around static-sensitive components[1][2]Lightweight chemical-resistant parts, automotive clips and ducting that must survive above 150 °C[10]
Diameter tolerance± mmNot documented±0.04 (Prusament)[3]
Printing Parameters
Nozzle temperature°C250–290 (Fiberon)[1]270 ± 10 (Prusament)[3]
Bed temperature°C70–80 (Fiberon); 70 (3DXTech)[1][2]85 ± 10 (Prusament)[3]
Enclosure / chamber requirement1–5Open frame is fine — Fiberon specifies room-temperature chamber[1]Enclosure recommended — Simplify3D lists an enclosure as a hardware requirement and Polymaker advises one below 70 °C ambient to stop warping and cracking[11][12]
Part cooling fanNot documentedOff — Prusa runs 0 % except 100 % on bridges[3]
Bed surface & adhesion aidTextured PEI, satin or powder-coated sheets; on smooth PEI a glue stick acts as a release agent[13][14]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][15]3.2 at Prusa's 40 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[3][15]
Warping tendency1–5Not documentedHigh — enclosure needed for reliable large parts; Prusa recommends a brim[3]
Bed-adhesion difficulty1–5Needs the right surface or a thin adhesive — the problem is releasing the part, not sticking it[13][14]Very difficult — special plates or slurry required[3]
Stringing / oozing tendency1–5Moderate — retraction tuning needed; Polymaker names stringing as PETG's common quirk[14]Not documented
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile; resistivity depends on getting the nozzle temperature right[1]Advanced — enclosure, hardware upgrades, tuning; hardened nozzle mandatory[3]
Extruder requirementNot documentedPrusa states a hardened nozzle is necessary and recommends a brim[3]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[1]Hardened steel required — Prusa states plainly that a hardened nozzle is necessary[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[16]Moderate — needs dry filament and a clean nozzle; 3DXTech specifies a hardened 0.4 mm minimum nozzle and 0.25 mm layers or higher, and Prusa lists composites as a higher clogging risk[4][17]
Heat-creep / jam sensitivity1–5Slightly sensitive[18]Not documented
Hotend requirementNo special hot-end required[18]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[13][16]Negligible (<0.1 % EMC) — Prusa measures 0.03 % in 24 h and 0.04 % in 7 days on its PP composite, the lowest figures it publishes for any filament[3]
Equilibrium moisture content at ~50 % RH%0.41 equilibrium water absorption (Fiberon PETG-ESD)[1]0.03 after 24 h and 0.04 after 7 days at 24 °C / 22 % RH (Prusa Polymers)[3]
Drying temperature & time65 °C for 3 h (Fiberon)[1]Not documented
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[19]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[19]Not applicable in practice at 0.04 % equilibrium uptake[3]
Storage requirementSealed with desiccant; Polymaker groups PETG with the highly hygroscopic materials[19][14]No special storage needed[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[25]Good[26]
Elasticity / flexibility1–5Slightly flexible in thin sections[1]Slightly flexible in thin sections[3]
Z strength as % of XY%57 (Fiberon, printed Z against XY tensile)[1]Not documented
Thermal Properties

Food contactNot certified for food contact as filament[14]Not documented
Biodegradability / compostabilityNot biodegradable[14]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]Not documented
Health & Safety
Fume toxicity1–5Moderate — measurable VOCs and UFPs, ventilation advised[28]Low hazard — minimal VOC and particle emission. Inferred: no polyolefin was among the nine filaments in the Azimi chamber study, so this is a family-level judgement rather than a measurement[28]
Ventilation / filtration requirement1–5Open a window / occasional ventilation[28]Open a window / occasional ventilation. Inferred — no polyolefin was measured in the chamber study[28]
Dust & fibre handling hazardConductive carbon filler is bound in the matrix; avoid inhaling sanding dust[1]Carbon 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[18]Not documented
Gluing & solvent weldingCyanoacrylate; no common solvent welds PETG cleanly[18]Not documented
Vapour / chemical smoothingNo practical vapour smoothing[18]Not documented
Support material pairingPrints its own supports; Polymaker rates PolyDissolve S1 for PETG[18]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.[29][30]None at room temperature; chloroform dissolves the matrix at 60 °C and xylene at about 118 °C, leaving the fibre.[31][32]
Softened or crazed byAcetone (+16 % weight over 1 year at 23 °C), ethyl acetate, toluene and DMF swell and soften it; methanol crazes it.[29]Xylene, decalin, CCl4 and chlorobenzene are heavily absorbed at 20 °C; oleum, chlorosulphonic acid and bromine destroy it.[31]
Solvent welding & smoothing agentDichloromethane brushed on is the only agent that smooths PETG — a controlled carcinogen, not workshop stock.[30]None — nothing softens PP at room temperature, so joints have to be welded thermally rather than chemically.[31]
