Bed surface & adhesion aidGlue stick, glass plate, Kapton tape or PET sheets[13]Textured PEI, satin or powder-coated sheets; on smooth PEI a glue stick acts as a release agent[12][15]
Warping tendency1–5Moderate — needs adhesion aid or draught shield[14]Not documented

Stringing / oozing tendency1–5Slight — HIPS oozes less than ABS[13][16]Moderate — retraction tuning needed; Polymaker names stringing as PETG's common quirk[15]
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile[14]Easy — minor profile tuning; Spectrum describes printing as similar to standard PETG[4]
Hardware Wear & Reliability

Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Low (0.1–0.3 %) — Simplify3D lists water resistance as a headline property[13]Moderate (0.3–0.8 %) — recycled PETG shares the virgin matrix, which reaches 0.40 % saturated at 25 °C / 55 % RH[12]

Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[19]Bubbling and popping at the nozzle, stringing and a rough surface[19]
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[19]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[19]
Storage requirementSealed with desiccant; less critical than for the polyamides[19]Sealed with desiccant; Polymaker groups PETG with the highly hygroscopic materials[19][15]

Hardness (scale-specific)Shore A / Shore D / RockwellNot documented74 Shore D (Prusa Polymers method) — the same as virgin Prusament PETG[3][12]

Health & Safety

VOC emission rateµg/min12–113 styrene, the range measured across ABS and the one HIPS filament tested[27]Not documented

Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration[27]Open a window / occasional ventilation[27]
Post-Processing
Sanding & machiningSands and paints readily, like ABS[26]Sands poorly — the material is tough and gums rather than powders[18]
Gluing & solvent weldingSolvent-welds with d-limonene, and with acetone via its polystyrene backbone[13][2]Cyanoacrylate; no common solvent welds PETG cleanly[18]
Vapour / chemical smoothingd-limonene attacks the surface; acetone smoothing is far less effective than on ABS[2][13]No practical vapour smoothing[18]
Support material pairingUsed as the support material itself — dissolves in d-limonene, or breaks away from ABS and ASA[2]Prints its own supports; Polymaker rates PolyDissolve S1 for PETG[18]
Solvents & Solubility
Soluble ind-limonene, 12–24 h submerged with occasional agitation; acetone also dissolves it, and xylene does so at 23 °C.[28][29][30]No common workshop solvent; 1,2-dichloroethane destroys it inside a week and dichloromethane — a carcinogen — dissolves the surface.[31][32]
Softened or crazed byLimonene also disrupts layer adhesion in some ABS and ASA grades, so an ABS model can flake apart in the same bath.[33]Acetone (+16 % weight over 1 year at 23 °C), ethyl acetate, toluene and DMF swell and soften it; methanol crazes it.[31]
Solvent welding & smoothing agentLimonene welds and lightly etches it; acetone welds through the polystyrene backbone but smooths less well than ABS.[28][33]Dichloromethane brushed on is the only agent that smooths PETG — a controlled carcinogen, not workshop stock.[32]
