Tougher than PLA, easier than ABS, happy in weather and warm rooms. When a part has a job to do and you don't want to overthink it, it's PETG.
PETG is what we reach for when a part has to actually work: it bends before it breaks, shrugs off water and most cleaners, and keeps its properties to about 70 °C. It's the material behind most of the brackets, fixtures and enclosures that leave our floor — at $0.121 a gram incl. GST, barely more than PLA.
Its layer welds are among the best of any FDM material, which means PETG parts behave more like the solid plastic you designed and less like a stack of laminations.
Brackets, mounts and clamps that carry real load
Outdoor hardware under cover — garden, marine, vehicle interiors
Parts that get wet, washed, or live around chemicals
Anything that must flex slightly and come back
Softer surface than PLA — scratches show on display parts
Slightly less dimensional precision than PLA (more squish)
Full Australian sun fades it over years — ASA is the UV pick
Strings more than PLA on intricate, gappy geometry
PETG's toughness comes with a little extra elasticity — for snap fits and clips it's the best mainstream choice we stock.
Use 0.3 mm clearances for mating PETG parts; its perimeter squish runs marginally wider than PLA's.
PETG-CF stiffens it considerably for structural parts that also face humidity — worth the step up for load-bearing outdoor brackets.
The classic: a bracket that holds something heavy to something else, indoors or out. PETG bends before it snaps.
Workshop tooling that gets clamped, knocked and oiled — see the jigs & fixtures page for the economics.
Electronics boxes and housings that see warm boards, the odd splash, and daily handling.
Indoors and no load: PLA, it's stiffer and cheaper. Anything functional, outdoors, warm, or wet: PETG. If you're torn, the quote tool reprices live when you switch material.
The base polymer is used in food packaging, but FDM layer lines harbour bacteria and our line isn't food-certified — so we don't recommend printed parts for repeated food contact.
Weather, yes — rain and temperature swings are fine. Years of direct Australian sun will eventually fade and embrittle it; for full-sun parts, choose ASA.
Upload an STL, STEP or 3MF, pick PETG in the configurator, and the price reprices live — GST included, dispatch date shown before you pay.
