Eolas Prints PETG pellets are 100% virgin, colourless polyethylene terephthalate glycol in granule form for pellet-fed 3D printers. PETG occupies the practical middle ground between PLA (easy to print, low heat resistance) and ABS (higher heat resistance, harder to print): it prints reliably without warping, offers significantly better heat and chemical resistance than PLA, and produces parts with good toughness and high surface clarity. In pellet form, PETG delivers these properties at a lower cost-per-kilogram than equivalent filament.

Key Specifications

PETG vs PLA vs ABS — When to Choose PETG

Choose PETG over PLA when the part will see temperatures above 55–60°C, will be exposed to moisture or mild chemicals, or needs better impact toughness than PLA provides. PETG's heat deflection temperature of approximately 70–80°C under light load makes it suitable for automotive interior parts, outdoor fixtures, and any application where PLA would soften.

Choose PETG over ABS when you don't have a heated enclosure, want to avoid the warping challenges of ABS, or need transparency. PETG prints without warping in open-air systems, produces significantly less VOC and styrene emissions than ABS, and its natural colourless state allows translucent and light-diffusing applications that ABS cannot achieve.

High Clarity Applications

Because these pellets are colourless and PETG has inherently high transparency, parts printed from them achieve a glass-like clarity when post-processed (light sanding and polishing). This makes them particularly well-suited for light pipes, display enclosures, laboratory vessels, transparent prototypes, and packaging applications where optical clarity is required.

Processing Notes

PETG is hygroscopic — it absorbs moisture from ambient air and will string or produce bubbles if printed wet. Dry pellets at 65–70°C for 4–6 hours before printing. Bed adhesion is excellent on PEI at 70–85°C; PETG bonds strongly, so use a thin release agent or textured surface to avoid tearing the PEI on removal.
