Frequently Asked Questions

What is the difference between Ultrafuse PET and PETG?
Ultrafuse PET prints at 215°C nozzle / 70°C bed (No enclosure, low moisture sensitivity). PETG prints at 230-250°C nozzle / 70-90°C bed (Optional enclosure, moderate moisture sensitivity).
Is Ultrafuse PET or PETG stronger?
Our dataset does not include comparable tensile strength values for both. Qualitatively, Ultrafuse PET is suited to tougher than pla, while PETG is suited to tougher than pla.
Which prints at a higher temperature, Ultrafuse PET or PETG?
PETG prints at a higher temperature (230-250°C nozzle vs 215°C for Ultrafuse PET).
Is Ultrafuse PET or PETG better for beginners?
Ultrafuse PET is better for beginners: enclosure is no and moisture sensitivity is low, vs optional enclosure and moderate moisture for PETG.
Should I use Ultrafuse PET or PETG for tougher than pla?
For tougher than pla, Ultrafuse PET is usually the better fit (Tougher than PLA). Choose PETG instead when tougher than pla.
