# PLA vs PETG: which should I use for functional parts?

Use PLA when the part is decorative or has no load-over-time, heat, or UV requirement. Use PETG when the part is functional. That split is what the on-topic comments say, and the print temperatures stay on each spool's row.

Functional parts go to PETG in the comment that actually makes the split. Decorative parts stay on PLA. Temperatures are the spool you loaded, not a single PLA-versus-PETG setpoint.
Heat, outdoor sun, and a part that creeps are [heat](/answers/heat), [outdoor PLA](/answers/pla_outdoor), and [PLA creep](/answers/pla_creep). The print process stays on [good PLA prints](/answers/pla_print) and [good PETG prints](/answers/petg_print).

## What the comments say

[a Reddit thread in r/BambuLab](https://www.reddit.com/r/BambuLab/comments/1weg5gw/): "I think PLA tends to have a much nicer finish so it better for figurines. PETG tends to be shinier even in matte. I reach for PETG for functional prints and PLA for decorative prints."

[a Reddit thread in r/BambuLab](https://www.reddit.com/r/BambuLab/comments/1weg5gw/): "PLA is easier to print, but if you have PETG, try that before buying PLA".

## Rows

[PolyLite PLA](/brand/polymaker/polylite-pla) lists 190–230 °C (374–446 °F), a bed of 25–60 °C (77–140 °F), and drying at 55 °C (131 °F) for 6 h. [PrimaSelect PLA](/brand/primacreator/primaselect-pla) lists 190–220 °C (374–428 °F) and 30–60 °C (86–140 °F). Its HDT in the [heat-resistance dataset](/data/filament-heat-resistance) is 57 °C (135 °F), ISO 75, load not stated. [PETG HF](/brand/bambu-lab/petg-hf) lists 230–260 °C (446–500 °F), 65–75 °C (149–167 °F), and drying at 65 °C (149 °F) for 8 h. [PrimaSelect PETG](/brand/primacreator/primaselect-petg) lists 225–245 °C (437–473 °F) and 70–80 °C (158–176 °F), and HDT 69 °C (156 °F), ISO 75, load not stated. Do not treat 57 °C (135 °F) and 69 °C (156 °F) as a ranking. The load is missing on both. [PLA](/material/pla) and [PETG](/material/petg) are the material hubs. [Polymaker](/brand/polymaker), [PrimaCreator](/brand/primacreator), and [Bambu Lab](/brand/bambu-lab) are the brand indexes.
