PLA vs PETG — Which Filament Should You Use?
A practical PLA vs PETG comparison — strength, heat resistance, printability, and use cases — so you pick the right filament for your project the first time.
PLA and PETG are the two most popular 3D printing filaments, and each one wins in different scenarios. Here's a practical breakdown to help you decide quickly.
PLA — the easiest and most detailed
PLA is easy to print, gives crisp detail and vivid colors, and needs no complex tuning, making it ideal for figurines, display models, gifts, and indoor decorative parts. It prints reliably on almost any machine, making it especially beginner-friendly, and produces a clean surface finish with sharp detail. It's also plant-based and biodegradable. Its one real limitation is heat resistance — it softens around 60°C, so don't leave it sitting in a hot car or in direct sun for long.
PETG — the strong, durable choice
PETG is stronger and more flexible than PLA, and handles heat, moisture, impact, and UV exposure noticeably better, making it the default pick for functional and mechanical parts, replacement parts, outdoor use, or anything that takes continuous stress. It does need slightly more tuned settings than PLA — moderate speed and low cooling — but it rewards you with significantly higher durability and impact resistance.
Which one to choose?
Pick PLA when looks matter most — models, prototypes, decor, fine detail. Pick PETG when the part will actually be used — a bracket, a spare, a tool, or anything exposed to heat or daily wear.
