PLA vs PETG: Which Filament Should You Choose?
Updated 2026-06-11 · by Jay
PLA and PETG are the two materials almost every print starts with — and the right choice depends on what the part needs to survive, not which one is "better".
The short answer
- Choose PLA for visual models, prototypes, low-stress brackets, and anything that lives indoors at room temperature. It prints easiest, looks sharpest, and comes in the most colors.
- Choose PETG for functional parts: enclosures, outdoor fittings, brackets under load, anything near warm electronics, and parts that flex rather than snap. If that's your job, jump to the best PETG filaments.
Strength: tough vs stiff
PLA is stiffer — it resists bending more before it gives. But when it gives, it snaps. PETG bends further and absorbs impacts that shatter PLA, which is why it's the default for printed tools, clips, and protective parts. Layer adhesion is also typically better with PETG, so parts loaded across layers fail less often.
Heat resistance
This is the clearest difference. PLA softens around 55-60°C — a car dashboard in summer will warp it. PETG holds shape to roughly 75-80°C, enough for most enclosures, light fixtures, and parts near electronics.
Printability
PLA is the most forgiving filament made: low temperatures (190-220°C), no enclosure, minimal warping, crisp overhangs. PETG runs hotter (230-250°C), strings more, and bonds too well to smooth build plates — use a textured plate or release agent. Both print fine without an enclosure.
Surface finish and color
PLA wins on looks: sharper detail, matte and silk variants, and the widest color selection (including most of the high-TD filaments HueForge users need). PETG has a naturally glossy, slightly translucent finish.
Price
Functionally a tie — mainstream spools of both run $15-25/kg, and the deal of the week matters more than the material. The live picks below come straight from FilaScope's price tracking.
