Identity & Market
Base polymer / chemistryPETG compounded with a conductive filler to bring surface resistivity into the static-dissipative range[1][2]Break-away support compounds matched to a specific model material — Polymaker sells separate grades for PLA and for PA12[3][4]
Densityg/cm³1.24 (Fiberon) and 1.28 (3DXTech), ISO 1183[1][2]1.22 (PolySupport for PLA) and 1.29 (PolySupport for PA12), 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 26–80; the middle of the market is about 45[5][7][8]
Price range across brandsUSD/kg66–140 across brands; Fiberon PETG-ESD 66, 3DXSTAT ESD-PETG 140[5][6]26–80 across brands and grades; IEMAI 3D E-REMOVE 26, Polymaker PolySupport for PLA 40 at 750 g, YXPOLYER 45, PolySupport for PA12 80 at 500 g[5][7][8]
Market availability1–5Niche, a handful of specialist brands[5][6]Available from several mainstream brands[5][6]
Spool sizes & diameters1.75 mm; 0.5, 0.75, 1 and 3 kg spools[5][6]1.75 and 2.85 mm; 0.5 and 0.75 kg spools[5]
Typical applicationsElectronics fixtures, trays and jigs handled around static-sensitive components[1][2]Support that peels off by hand, avoiding the moisture handling and dissolution time that soluble supports demand[3]
Printing Parameters
Nozzle temperature°C250–290 (Fiberon)[1]220–230 (PolySupport for PLA)[3]
Bed temperature°C70–80 (Fiberon); 70 (3DXTech)[1][2]25–60 (PolySupport for PLA)[3]
Enclosure / chamber requirement1–5Open frame is fine — Fiberon specifies room-temperature chamber[1]Open frame is fine[3]
Bed surface & adhesion aidTextured PEI, satin or powder-coated sheets; on smooth PEI a glue stick acts as a release agent[9][10]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][11]4–12 at Polymaker's 50–150 mm/s on a 0.4 mm nozzle at 0.2 mm layer[3]
Bed-adhesion difficulty1–5Needs the right surface or a thin adhesive — the problem is releasing the part, not sticking it[9][10]Not documented
Stringing / oozing tendency1–5Moderate — retraction tuning needed; Polymaker names stringing as PETG's common quirk[10]Not documented
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile; resistivity depends on getting the nozzle temperature right[1]Easy — minor profile tuning[3]
Extruder requirementNot documentedA second extruder or a tool changer[3]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[1]Brass fine indefinitely[3]
Abrasiveness1–5Moderately abrasive — conductive carbon filler[1]Non-abrasive[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[12]Moderate — needs dry filament and a clean nozzle; Polymaker specifies a 55 °C dry for the PLA grade and warns brass nozzle life falls to about 9 h on the PA12 grade[3][4]
Heat-creep / jam sensitivity1–5Slightly sensitive[13]Not documented
Hotend requirementNo special hot-end required[13]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[9][12]Moderate — 0.64 % equilibrium water absorption (PolySupport for PLA)[3]
Equilibrium moisture content at ~50 % RH%0.41 equilibrium water absorption (Fiberon PETG-ESD)[1]0.64 equilibrium water absorption (Polymaker PolySupport for PLA)[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[14]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[14]Not a structural material; no dry-versus-conditioned data is published[14]
Storage requirementSealed with desiccant; Polymaker groups PETG with the highly hygroscopic materials[14][10]Not documented
Mechanical Properties
Tensile strength (XY)MPa36.1 ± 0.9 printed XY, ISO 527 (Fiberon); 3DXTech quotes 50 at break[1][2]Not documented
Young's modulusMPa1983 ± 75 printed XY, ISO 527 (Fiberon)[1]Not documented
Elongation at break%7.3 ± 0.7 printed XY, ISO 527 (Fiberon); 3DXTech quotes 13 at break[1][2]Not documented
Flexural strengthMPa54.0 ± 2.5 printed XY, ISO 178 (Fiberon)[1]Not documented
Flexural modulusMPa1651 ± 141 printed XY, ISO 178 (Fiberon)[1]Not documented

Layer adhesion / Z tensileMPa20.7 ± 0.6 printed Z, ISO 527 (Fiberon)[1]Not documented
Brittleness1–5Moderate[1]Not documented
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[15][16][17][18]Not documented
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[19]Not documented
Elasticity / flexibility1–5Slightly flexible in thin sections[1]Not documented
Z strength as % of XY%57 (Fiberon, printed Z against XY tensile)[1]Not documented
Thermal Properties
HDT at 0.45 MPa°C76 (ISO 75, 0.45 MPa, Fiberon)[1]43 (ISO 75, 0.45 MPa, PolySupport for PA12). Polymaker's sheet prints a higher figure at the higher load, which is physically inverted; treat both HDT numbers as approximate[4]
HDT at 1.8 MPa°C72 (ISO 75, 1.8 MPa, Fiberon)[1]53 (ISO 75, 1.8 MPa, PolySupport for PA12) — printed above the 0.45 MPa figure on Polymaker's own sheet, which cannot be right; treat both as approximate[4]
Glass transition (Tg)°C77 (Fiberon) and 80 (3DXTech), DSC[1][2]Not documented
Melting point / Vicat°CAmorphous — no melting point; Vicat 86 (Fiberon, ISO 306)[1]Vicat 171 (PolySupport for PA12, ISO 306)[4]
Flammability / UL 94Flammable; no UL 94 rating published for standard grades[20]Not documented
Environment & Chemical
Chemical resistanceWithstands acids, alkalis, oils and UV exposure[10]Not documented
Food contactNot certified for food contact as filament[10]Not documented
Biodegradability / compostabilityNot biodegradable[10]Not documented
RecyclabilityNot accepted in household plastic collection[10]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 resistance above 10^13 ohm/sq (ASTM D257, THERMAX HTS2 and MTS1)[21][22]
Health & Safety
Fume toxicity1–5Moderate — measurable VOCs and UFPs, ventilation advised[23]Low hazard — minimal VOC and particle emission; none of these materials was in the chamber study[23]
Ventilation / filtration requirement1–5Open a window / occasional ventilation[23]Open a window / occasional ventilation[23]
Dust & fibre handling hazardConductive carbon filler is bound in the matrix; avoid inhaling sanding dust[1]Not documented
Post-Processing
Sanding & machiningSands poorly — the material is tough and gums rather than powders[13]Not documented
Gluing & solvent weldingCyanoacrylate; no common solvent welds PETG cleanly[13]Not documented
Vapour / chemical smoothingNo practical vapour smoothing[13]Not documented
Support material pairingPrints its own supports; Polymaker rates PolyDissolve S1 for PETG[13]This is the support material. Polymaker publishes an adhesion matrix per model material, from very good to unusable, because break-away supports only work against the polymer they were matched to[3][4]
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.[24][25]None — break-away support is removed mechanically; 3DXTech lists no water or solvent route for it.[26]
Softened or crazed byAcetone (+16 % weight over 1 year at 23 °C), ethyl acetate, toluene and DMF swell and soften it; methanol crazes it.[24]Not documented
Solvent welding & smoothing agentDichloromethane brushed on is the only agent that smooths PETG — a controlled carcinogen, not workshop stock.[25]None — there is no solvent to weld or smooth with.[26]
