Why Choose PETG for Your Parts?

PETG is the material we recommend most often when clients need a reliable, cost-effective material for functional parts. It's a modified version of PET — the same plastic used in water bottles — with added glycol for improved printability and impact resistance.

What makes PETG stand out is its combination of properties at the price point. You get better strength than PLA, better chemical resistance than ABS, food-safe certification, and excellent layer adhesion — all at one of the lowest per-part costs in our material lineup. For clients producing hundreds or thousands of parts, PETG keeps unit costs down without sacrificing quality.

Advantages
  • Excellent strength-to-cost ratio — best value for volume production
  • FDA food-safe compliant for food contact applications
  • Good chemical resistance to acids, bases, and many solvents
  • Very low warping and shrinkage — reliable for large parts
  • Superior layer adhesion — strong inter-layer bonds
  • Moisture resistant — doesn't absorb water like nylon
  • Available in transparent, translucent, and opaque colors
Considerations
  • Lower heat resistance (~80°C) than ABS, ASA, or nylon
  • Strings during printing — requires skilled setup for clean results
  • Difficult to sand and post-process compared to ABS
  • Not UV-stable for long-term outdoor use — use ASA instead
  • Slightly lower stiffness than ABS

Common Applications for 3D Printed PETG

Food-Contact Components
Custom funnels, dispensers, trays, sorting tools, and packaging inserts for food processing and food service applications.
Enclosures & Brackets
Electronics housings, mounting brackets, cable management, and protective covers. PETG's low warping makes it reliable for larger enclosures.
Medical & Lab Equipment
Chemical-resistant fixtures, sample holders, custom lab tools, and non-implant medical device components. Easy to sterilize.
Volume Production Runs
When you need hundreds or thousands of functional parts at the lowest per-unit cost. PETG's reliability means consistent quality at scale.
Water-Contact Applications
Water filtration components, plumbing fixtures, aquarium parts, and irrigation fittings. PETG doesn't absorb moisture or degrade in wet environments.
Display & POP Materials
Point-of-purchase displays, product holders, and retail fixtures. Available in clear/translucent for backlit applications.

Frequently Asked Questions

PETG resin is FDA-approved for food contact. However, 3D printed parts have layer lines that can harbor bacteria, so food-safe PETG parts should be coated with a food-safe epoxy or used for dry food contact only. We can advise on the best approach for your specific application.
PETG typically costs 30–50% less per part than nylon, depending on size and complexity. For volume runs of 100+ units, the savings are significant. If your application doesn't require nylon's extreme chemical or temperature resistance, PETG is usually the smarter economic choice.
PETG handles moisture and temperature well, but it has limited UV resistance. For short-term outdoor use or covered outdoor areas, it's fine. For long-term direct sun exposure, we recommend ASA instead — it's specifically engineered for UV stability.
We stock PETG in black, white, grey, clear (transparent), and natural (translucent). Additional colors are available with slightly longer lead times. Clear PETG is popular for light pipes, windows, and display applications.
