PETG 3D Printing Service
PETG (Polyethylene Terephthalate Glycol) hits the sweet spot between PLA's ease of use and engineering-grade performance. It's tougher, more heat-resistant, and more chemically stable than PLA which makes it the go-to choice for functional parts that need to survive real-world conditions.
If your part goes outdoors, handles mechanical loads, or lives near heat sources, PETG is probably your material. All PETG parts are printed in-house via FDM printing.

- Functional prototypes that need to survive testing
- Outdoor enclosures and housings (UV resistant)
- Mechanical components like brackets, mounts, or clips
- Fixtures and jigs for production environments
- Parts exposed to moisture or chemicals
- Anything that needs more durability than PLA at a reasonable cost

PETG vs PLA — Which Do You Need?
PLA is cheaper, stiffer, and gives a slightly better surface finish right off the printer. But PETG wins everywhere it matters for functional parts:
- Heat resistance: PETG handles 69°C vs PLA's 57°C
- Impact strength: PETG bends before breaking, PLA is more brittle
- Outdoor use: PETG resists UV and moisture
Rule of thumb: if the part is just for looking at, use PLA. If it needs to do something, use PETG.
Frequently Asked Questions
Is PETG stronger than PLA?
Yes. PETG has higher impact strength and toughness (it bends instead of breaking), better chemical and UV resistance, and handles higher temperatures (69°C vs 57°C). It's the better choice for anything functional or outdoor.
Can PETG go outside?
Yes. PETG has good UV resistance and handles moisture well. It's one of the best FDM materials for outdoor applications.
How much more does PETG cost than PLA?
Slightly more, typically 10–20% higher than PLA for the same part.
