Is PETG Food Safe?
Why raw PETG is food-safe
PETG is part of the PET family, the same resin used for clear plastic drink bottles. It does not contain BPA, phthalates or other harmful additives in standard food-grade formulations.
Why printed PETG is not
- FDM prints have microscopic gaps between layers
- Moisture and food residue collect in those gaps
- Bacteria colonise the gaps over a few uses
- Washing does not reach all the gaps
Reducing the risk (still not certified food-safe)
- Stainless steel or food-safe nozzle for printing
- Food-safe epoxy or polyurethane coating on the finished print
- Accept the print as a single-use item
- Use injection-moulded food vessels for serious food contact applications
