Typical applicationsStiff, dimensionally stable enclosure and tooling parts; Bambu Lab notes the fibre blurs layer lines into a matte finish[2]Electronics fixtures, trays and jigs handled around static-sensitive components[3][4]
Printing Parameters
Nozzle temperature°C240–280 (Bambu Lab)[2]250–290 (Fiberon)[3]
Bed temperature°C80–100 (Bambu Lab)[2]70–80 (Fiberon); 70 (3DXTech)[3][4]
Enclosure / chamber requirement1–5Enclosure recommended — Bambu Lab specifies a 45–60 °C chamber[2][10]Open frame is fine — Fiberon specifies room-temperature chamber[3]
Recommended chamber temperature°C45–60 (Bambu Lab)[2]Not documented
Part cooling fan0–80 % (Bambu Lab)[2]Not documented
Bed surface & adhesion aidClean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[10][11]Textured PEI, satin or powder-coated sheets; on smooth PEI a glue stick acts as a release agent[12][13]
Maximum volumetric flow (mm³/s; see test conditions)mm³/s14 at Bambu Lab's 180 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[2][14]Fiberon 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[3][14]
Warping tendency1–5Moderate — needs adhesion aid or draught shield; Bambu Lab positions the fibre as reducing warping[2]Not documented
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[10]Needs the right surface or a thin adhesive — the problem is releasing the part, not sticking it[12][13]
Stringing / oozing tendency1–5Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[15]Moderate — retraction tuning needed; Polymaker names stringing as PETG's common quirk[13]
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile; hardened nozzle mandatory[10]Intermediate — dry filament and a tuned profile; resistivity depends on getting the nozzle temperature right[3]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[10]Hardened steel required[3]
Abrasiveness1–5Highly abrasive — standard GF composite[10]Moderately abrasive — conductive carbon filler[3]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle; 3DXTech specifies a hardened 0.4 mm minimum nozzle and 0.25 mm layers or higher for the glass-filled grade[16][17]Low — 3DXTech lists no special nozzle concerns and no minimum layer height for its ESD-PETG, only a 65 °C pre-dry[18]

Hotend requirementNo special hot-end required[11]No special hot-end required[19]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate — 0.53 % saturated at 25 °C / 55 % RH (Bambu Lab)[2]Moderate (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][18]
Equilibrium moisture content at ~50 % RH%0.53 saturated at 25 °C / 55 % RH (Bambu Lab)[2]0.41 equilibrium water absorption (Fiberon PETG-ESD)[3]
Drying temperature & time80 °C for 8 h (Bambu Lab)[2]65 °C for 3 h (Fiberon)[3]
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[20]Bubbling and popping at the nozzle, stringing and a rough surface[20]
Effect of moisture on strengthPolymaker rates ABS moderate-sensitivity and publishes no dry-versus-conditioned figures; absorbed water flashes to steam in the hotend and shows as bubbling and poor layer adhesion[20]Polymaker 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[20]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity[20]Sealed with desiccant; Polymaker groups PETG with the highly hygroscopic materials[20][13]

Environment & Chemical

Electrical & ESD propertiesNot documentedSurface 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[3][4]
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[29][10]Moderate — measurable VOCs and UFPs, ventilation advised[29]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[29]Not documented
Ultrafine-particle emission rateparticles/min2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[29]Not documented
Hazardous species emittedStyrene dominates. Bambu Lab states ABS and ASA release harmful gases such as styrene at printing temperature, which can be toxic and cause dizziness or nausea[29][10]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[29][10]Open a window / occasional ventilation[29]
Dust & fibre handling hazardGlass fibre is bound in the matrix; avoid inhaling sanding dust[1]Conductive carbon filler is bound in the matrix; avoid inhaling sanding dust[3]
Post-Processing
Sanding & machiningSands well and takes filler before painting[15]Sands poorly — the material is tough and gums rather than powders[19]
Painting & finishingPaints readily after light abrasion[15]Not documented
Gluing & solvent weldingNot documentedCyanoacrylate; no common solvent welds PETG cleanly[19]
Vapour / chemical smoothingNot documentedNo practical vapour smoothing[19]
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[30][10]Prints its own supports; Polymaker rates PolyDissolve S1 for PETG[19]
Dimensional accuracy & detailBambu Lab describes a smooth matte finish with micro-spot gloss that blurs layer lines[2]Nozzle temperature has to be held steady — it moves surface resistivity by three orders of magnitude[3]
Solvents & Solubility
Soluble inAcetone dissolves the resin and leaves the fibre as sludge; MEK, THF, ethyl acetate and chlorinated solvents do the same.[31][28]No common workshop solvent; 1,2-dichloroethane destroys it inside a week and dichloromethane — a carcinogen — dissolves the surface.[32][33]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[31][34]Acetone (+16 % weight over 1 year at 23 °C), ethyl acetate, toluene and DMF swell and soften it; methanol crazes it.[32]
Solvent welding & smoothing agentAcetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[33][28]Dichloromethane brushed on is the only agent that smooths PETG — a controlled carcinogen, not workshop stock.[33]
