Identity & Market
Base polymer / chemistryPETG compounded with a conductive filler to bring surface resistivity into the static-dissipative range[1][2]PLA filled with stone or mineral powder — Formfutura StoneFil declares 40–50 wt% stone powder[3][4]

Market availability1–5Niche, a handful of specialist brands[5][6]Stocked by most mainstream brands[7][5][8]
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 1 kg spools plus refills[5][3]

Printing Parameters
Nozzle temperature°C250–290 (Fiberon)[1]190–230 (Bambu Lab)[4]
Bed temperature°C70–80 (Fiberon); 70 (3DXTech)[1][2]35–45 (Bambu Lab)[4]
Enclosure / chamber requirement1–5Open frame is fine — Fiberon specifies room-temperature chamber[1]Open frame is fine[4]
Part cooling fanNot documentedFan on[4]
Bed surface & adhesion aidTextured PEI, satin or powder-coated sheets; on smooth PEI a glue stick acts as a release agent[12][13]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][14]Not documented
Bed-adhesion difficulty1–5Needs the right surface or a thin adhesive — the problem is releasing the part, not sticking it[12][13]Not documented
Stringing / oozing tendency1–5Moderate — retraction tuning needed; Polymaker names stringing as PETG's common quirk[13]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; 0.2 mm nozzles are not usable[15]
Extruder requirementNot documentedNozzles below 0.4 mm are not compatible (Bambu Lab)[15]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[1]Brass acceptable; hardened steel for volume work — Bambu Lab's compatibility table says no hardened nozzle is needed while the note under the same table groups PLA Marble with particle-filled materials that should always use one[15]
Abrasiveness1–5Moderately abrasive — conductive carbon filler[1]Moderately abrasive — stone fill[15][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[15]
Heat-creep / jam sensitivity1–5Slightly sensitive[17]Not documented
Hotend requirementNo special hot-end required[17]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[12][16]Moderate — 0.44 % saturated at 25 °C / 55 % RH[4]
Equilibrium moisture content at ~50 % RH%0.41 equilibrium water absorption (Fiberon PETG-ESD)[1]0.44 saturated at 25 °C / 55 % RH (Bambu Lab)[4]
Drying temperature & time65 °C for 3 h (Fiberon)[1]Not documented
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[18]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[18]Polymaker rates PLA low-sensitivity and publishes no dry-versus-conditioned figures for this grade; absorbed water flashes to steam and shows as bubbling and poor layer adhesion[18]
Storage requirementSealed with desiccant; Polymaker groups PETG with the highly hygroscopic materials[18][13]Not documented

Layer adhesion / Z tensileMPa20.7 ± 0.6 printed Z, ISO 527 (Fiberon)[1]30 ± 4 printed Z, ISO 527 (Bambu Lab)[4]
Brittleness1–5Moderate[1]Brittle — snaps with little warning[4]
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[19][20][21][22]Poor — no stone-filled creep test; plain printed PLA sagged from 12 to 16.2–21.8 mm over 5 days at 1.25 kg[23][24][25]
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[26]Poor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength and the mineral filler leaves a brittle compound[26][4]

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[29]Low hazard — minimal VOC and particle emission[29]
Ventilation / filtration requirement1–5Open a window / occasional ventilation[29]None needed in a normal room[29]
Dust & fibre handling hazardConductive carbon filler is bound in the matrix; avoid inhaling sanding dust[1]Formfutura's SDS sets an occupational limit of 1 mg/m³ for the stone powder and lists it as both a fibre and a particulate — do not dry-sand without extraction[3]
Post-Processing
Sanding & machiningSands poorly — the material is tough and gums rather than powders[17]Sands to a stone-like matte surface[3]
Gluing & solvent weldingCyanoacrylate; no common solvent welds PETG cleanly[17]Not documented
Vapour / chemical smoothingNo practical vapour smoothing[17]Not documented
Support material pairingPrints its own supports; Polymaker rates PolyDissolve S1 for PETG[17]Support for PLA (Bambu Lab)[4]
Dimensional accuracy & detailNozzle temperature has to be held steady — it moves surface resistivity by three orders of magnitude[1]Matte mineral surface hides layer lines; 55° overhangs and 30 mm bridges as for plain PLA[4]
Solvents & Solubility
Soluble inNo common workshop solvent; 1,2-dichloroethane destroys it inside a week and dichloromethane — a carcinogen — dissolves the surface.[30][31]Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[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.[30]Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[32][31]
Solvent welding & smoothing agentDichloromethane brushed on is the only agent that smooths PETG — a controlled carcinogen, not workshop stock.[31]Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[33][31]
