Identity & Market
Base polymer / chemistryPETG compounded with a conductive filler to bring surface resistivity into the static-dissipative range[1][2]Break-away support compounded to survive high-temperature print chambers; 3DXTech sells separate grades for PC/ABS and for the PAEK and PEI class[3][4]
Densityg/cm³1.24 (Fiberon) and 1.28 (3DXTech), ISO 1183[1][2]1.37 (3DXTech THERMAX HTS1, ISO 1183)[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 168[6]
Price range across brandsUSD/kg66–140 across brands; Fiberon PETG-ESD 66, 3DXSTAT ESD-PETG 140[5][6]100–290 across grades; 3DXTech THERMAX MTS1 100 at 2 kg, HTS2 168 at 250 g, HTS1 250 at 500 g, IEMAI 3D HT-SP 290 at 1 kg[6][7]

Spool sizes & diameters1.75 mm; 0.5, 0.75, 1 and 3 kg spools[5][6]1.75 mm; 250 g, 500 g, 1 kg and 2 kg spools[6]
Typical applicationsElectronics fixtures, trays and jigs handled around static-sensitive components[1][2]Support for PEEK, PEI and PC-class prints, where PVA and PLA-based supports would decompose[3][4]
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]Actively heated chamber required — it is used inside high-temperature builds[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
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]
Extruder requirementNot documentedA dual-extruder machine rated for high-temperature materials; 3DXTech states the grade is intended for dual-extruder printers designed to print high-temp materials[11]
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; 3DXTech lists no special nozzle concerns but a mandatory 120 °C pre-dry for HTS1 and 80 °C for MTS1[11][13]
Heat-creep / jam sensitivity1–5Slightly sensitive[14]Not documented
Hotend requirementNo special hot-end required[14]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[8][12]Not documented
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[15]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[15]No dry-versus-conditioned figures are published; 3DXTech mandates a 120 °C, 4 h pre-dry for HTS1 and 80 °C for MTS1 because trapped water flashes to steam at these nozzle temperatures[11][13]
Storage requirementSealed with desiccant; Polymaker groups PETG with the highly hygroscopic materials[15][9]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[20]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
Wear resistance & frictionNot documented3DXTech marks tensile strength, modulus and elongation as not applicable for its support grades — they are not characterised as structural materials[3]

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]Surface resistance above 10^13 ohm/sq on all three THERMAX support grades (ASTM D257) — insulating[3][22][4]
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[14]Not documented
Gluing & solvent weldingCyanoacrylate; no common solvent welds PETG cleanly[14]Not documented
Vapour / chemical smoothingNo practical vapour smoothing[14]Not documented
Support material pairingPrints its own supports; Polymaker rates PolyDissolve S1 for PETG[14]This is the support material. MTS1 is matched to PC/ABS and PC; HTS1 and HTS2 to the higher-temperature classes[4][3]
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]Aqueous alkali, not water: IEMAI specifies an alkaline bath in an ultrasonic cleaner until the support dissolves.[7]
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 — the alkaline bath dissolves the support rather than welding anything.[7]

Material entries describe families or representative grades, not an interchangeable specification for every spool. Test methods, orientations and conditions may differ.
