Identity & Market
Base polymer / chemistryPETG compounded with a conductive filler to bring surface resistivity into the static-dissipative range[1][2]Polyvinylidene fluoride — a semi-crystalline fluoropolymer[3][4]
Densityg/cm³1.24 (Fiberon) and 1.28 (3DXTech), ISO 1183[1][2]1.71 (ISO 1183) — the densest unfilled filament in the dataset[3]
Typical priceUSD/kg1 kg-equivalent spools span 66–140; the middle of the market is about 103[5][6]1 kg-equivalent spools cluster near 251[6]
Price range across brandsUSD/kg66–140 across brands; Fiberon PETG-ESD 66, 3DXSTAT ESD-PETG 140[5][6]251 at 3DXTech's 750 g pricing — the most expensive material in the whole dataset[6]
Market availability1–5Niche, a handful of specialist brands[5][6]Special order, 1–2 makers worldwide[6][7]
Spool sizes & diameters1.75 mm; 0.5, 0.75, 1 and 3 kg spools[5][6]1.75 and 2.85 mm; 750 g spools[6]
Typical applicationsElectronics fixtures, trays and jigs handled around static-sensitive components[1][2]Chemical-plant fittings, semiconductor handling and parts needing outstanding UV and chemical resistance[3]
Printing Parameters
Nozzle temperature°C250–290 (Fiberon)[1]Not documented
Bed temperature°C70–80 (Fiberon); 70 (3DXTech)[1][2]70–110 (3DXTech FluorX)[3]
Enclosure / chamber requirement1–5Open frame is fine — Fiberon specifies room-temperature chamber[1]Enclosure required (passive)[3]
Bed surface & adhesion aidTextured PEI, satin or powder-coated sheets; on smooth PEI a glue stick acts as a release agent[8][9]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][10]Not documented
Warping tendency1–5Not documentedHigh — enclosure needed for reliable large parts[3]
Bed-adhesion difficulty1–5Needs the right surface or a thin adhesive — the problem is releasing the part, not sticking it[8][9]Not documented
Stringing / oozing tendency1–5Moderate — retraction tuning needed; Polymaker names stringing as PETG's common quirk[9]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][4]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[1]Brass fine indefinitely for unfilled grades[3]
Abrasiveness1–5Moderately abrasive — conductive carbon filler[1]Non-abrasive when unfilled[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[11]Low — 3DXTech lists no special nozzle concerns, no minimum layer height and states drying is not required[7]
Heat-creep / jam sensitivity1–5Slightly sensitive[12]Not documented
Hotend requirementNo special hot-end required[12]Not documented
Other hardware wearNot documentedHydrogen fluoride released on overheating is extremely corrosive and will attack hotend and enclosure metalwork as well as people[4]
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[8][11]Negligible (<0.1 % EMC) — fluoropolymers are essentially non-hygroscopic[3]
Equilibrium moisture content at ~50 % RH%0.41 equilibrium water absorption (Fiberon PETG-ESD)[1]Not documented
Drying temperature & time65 °C for 3 h (Fiberon)[1]Not documented
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[13]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[13]Not applicable in practice — 3DXTech states drying is not required for PVDF, so there is no moisture-driven strength loss to measure[7]
Storage requirementSealed with desiccant; Polymaker groups PETG with the highly hygroscopic materials[13][9]Not documented

Continuous service temperature°CNot documented149 long term and short term on extruded PVDF stock (converted from 300 °F)[14]
Thermal expansion (CTE)µm/m·KNot documented127.8 (extruded PVDF stock, ASTM D696; source states 7.1e-5 in/in/°F) — the highest thermal expansion of any engineering polymer in this dataset[14]
Flammability / UL 94Flammable; no UL 94 rating published for standard grades[20]UL 94 V-0 on extruded PVDF stock; Ensinger lists inherent flame resistance[14]
Environment & Chemical
UV resistance1–5Not documentedExcellent — designed for permanent outdoor use; Ensinger lists good UV and weather resistance and high gamma radiation resistance for PVDF stock[3][14]
Chemical resistanceWithstands acids, alkalis, oils and UV exposure[9]Outstanding — resistant to most acids, solvents and oxidising agents, which is the reason to use it[3]

Food contactNot certified for food contact as filament[9]Not documented
Biodegradability / compostabilityNot biodegradable[9]Not documented
RecyclabilityNot accepted in household plastic collection[9]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[21]Very high — toxic decomposition products; local exhaust mandatory. Above 315 °C thermal decomposition yields hydrofluoric acid, hydrogen cyanide and carbon monoxide[4]
Hazardous species emittedNot documentedAbove 315 °C: hydrofluoric acid, hydrogen cyanide, phenols, carbon monoxide, carbon dioxide and dense smoke. HF is extremely corrosive, its skin burns may not be immediately visible or painful, and exposure can be fatal by skin absorption, inhalation or ingestion[4]
Ventilation / filtration requirement1–5Open a window / occasional ventilation[21]Local exhaust to outside / fume hood — the SDS states local exhaust is preferred[4]
Dust & fibre handling hazardConductive carbon filler is bound in the matrix; avoid inhaling sanding dust[1]Molten polymer causes thermal burns and must not be pulled off the skin. If HF is detected during a decomposition event, cut the heat but keep the extraction running, ventilate, and clear non-essential people from the area[4]
Post-Processing
Sanding & machiningSands poorly — the material is tough and gums rather than powders[12]Not documented
Gluing & solvent weldingCyanoacrylate; no common solvent welds PETG cleanly[12]Not documented
Vapour / chemical smoothingNo practical vapour smoothing[12]Not documented
Support material pairingPrints its own supports; Polymaker rates PolyDissolve S1 for PETG[12]Not documented
Dimensional accuracy & detailNozzle temperature has to be held steady — it moves surface resistivity by three orders of magnitude[1]The processing window sits well below the 315 °C decomposition threshold, so nozzle temperature must be controlled rather than raised to chase flow[3][4]
Solvents & Solubility
Soluble inNo common workshop solvent; 1,2-dichloroethane destroys it inside a week and dichloromethane — a carcinogen — dissolves the surface.[22][23]THF, MEK, DMF, DMAc, NMP, DMSO and trimethyl phosphate dissolve 5–10 wt% at ambient — Arkema's active solvents, all lab reagents.[24]
Softened or crazed byAcetone (+16 % weight over 1 year at 23 °C), ethyl acetate, toluene and DMF swell and soften it; methanol crazes it.[22]Acetone, MIBK, cyclohexanone, butyl acetate and glycol ethers swell it; alkalis above pH 12 attack the homopolymer.[24][25]
Solvent welding & smoothing agentDichloromethane brushed on is the only agent that smooths PETG — a controlled carcinogen, not workshop stock.[23]None for the workshop — the active solvents (NMP, DMAc, DMF) are laboratory reagents used for casting membranes, not joints.[24]
