Identity & Market
Base polymer / chemistryPETG compounded with a conductive filler to bring surface resistivity into the static-dissipative range[1][2]Polyvinyl butyral — a printable thermoplastic whose surface can be smoothed with isopropyl alcohol instead of a hot solvent[3]
Densityg/cm³1.24 (Fiberon) and 1.28 (3DXTech), ISO 1183[1][2]1.10 (Polymaker PolySmooth, ISO 1183); Prusament PVB 1.10[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 cluster near 80[5][7]
Price range across brandsUSD/kg66–140 across brands; Fiberon PETG-ESD 66, 3DXSTAT ESD-PETG 140[5][6]49–102 across brands; Polymaker PolySmooth 49 at 750 g, Prusament PVB 80–102 at 500 g[5][7]
Market availability1–5Niche, a handful of specialist brands[5][6]Available from several mainstream brands[5][7]
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][7]
Typical applicationsElectronics fixtures, trays and jigs handled around static-sensitive components[1][2]Display models and light guides where a layer-free surface matters more than strength[3]
Diameter tolerance± mmNot documented+/- 0.03 (Prusament PVB)[4]
Printing Parameters
Nozzle temperature°C250–290 (Fiberon)[1]215 +/- 10 (Prusament PVB)[4]
Bed temperature°C70–80 (Fiberon); 70 (3DXTech)[1][2]75 +/- 5 (Prusament PVB)[4]
Enclosure / chamber requirement1–5Open frame is fine — Fiberon specifies room-temperature chamber[1]Open frame is fine[3]
Part cooling fanNot documented100 % part cooling (Prusament PVB)[4]
Bed surface & adhesion aidTextured PEI, satin or powder-coated sheets; on smooth PEI a glue stick acts as a release agent[8][9]Smooth PEI sheet or satin sheet; Prusa states a brim is not generally necessary[4]
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]Easy — minor profile tuning; it prints close to PLA[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[11]Moderate — needs dry filament and a clean nozzle; Prusa calls PVB very prone to absorbing moisture and requires a 60 °C, 4 h dry before every print[12][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][11]Very high (>2 %) — 2.36 % equilibrium water absorption (Polymaker PolySmooth), above every PLA and PETG grade here[3]
Equilibrium moisture content at ~50 % RH%0.41 equilibrium water absorption (Fiberon PETG-ESD)[1]2.36 equilibrium water absorption (Polymaker PolySmooth); 2.09 for PolyCast; Prusament PVB takes up 0.18 in 24 h and 0.35 in 7 days at 24 °C and 22 % RH[3][15][4]
Drying temperature & time65 °C for 3 h (Fiberon)[1]Maximum 60 °C for 4-8 h depending on how wet the filament is (Prusament PVB)[4]
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]Polymaker publishes no dry-versus-conditioned figures; at 2.36 % equilibrium uptake the material has to be kept dry to print cleanly[3][13]
Storage requirementSealed with desiccant; Polymaker groups PETG with the highly hygroscopic materials[13][9]Sealed with desiccant[13]

Biodegradability / compostabilityNot biodegradable[9]Not documented

Health & Safety
Fume toxicity1–5Moderate — measurable VOCs and UFPs, ventilation advised[22]Low hazard — minimal VOC and particle emission; none of these materials was in the chamber study[22]
Ventilation / filtration requirement1–5Open a window / occasional ventilation[22]Open a window / occasional ventilation[22]
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]Isopropyl alcohol vapour smoothing is the point of the material — Polymaker markets PolySmooth for hands-free post-processing to a layer-free surface[3]
Support material pairingPrints its own supports; Polymaker rates PolyDissolve S1 for PETG[14]PolyDissolve S1 is rated for PVB (Polymaker)[23]
Dimensional accuracy & detailNozzle temperature has to be held steady — it moves surface resistivity by three orders of magnitude[1]PolyCast is the investment-casting variant of the same chemistry — it burns out cleanly rather than being smoothed[15]
Solvents & Solubility
Soluble inNo common workshop solvent; 1,2-dichloroethane destroys it inside a week and dichloromethane — a carcinogen — dissolves the surface.[24][25]Isopropyl alcohol dissolves it; Prusa describes PVB as soluble only in IPA, and it is not water-soluble.[12]
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]Isopropyl alcohol: brushed or sprayed on for speed, or several hours in IPA vapour for a glass-like surface.[25][12]
