What is PETG?
PETG is a modified version of PET (the most commonly used plastic in the world) The ‘G’ stands for “glycol-modified”, which is added to the material composition during polymerisation. The result is a filament that is clearer, less brittle, and easier to use than its base form of PET. Our PETG filament has the reputation of combining the functionality of ABS (stronger, temperature resistant, more durable) and reliability of PLA (easy to print) in one material.
It is food and skin safe, so it can be used in medical and food applications. In medical applications, it stands up to radiation and chemical sterilization techniques without changing colour. It is not hygroscopic and is also chemical resistant. PETG’s low shrink rate makes it ideal for large prints, or where tolerance can be an issue.
PETG PRINTING TIPS
PETG has a higher melting temperature than PLA so we recommend setting your hot-end temperature between 230 and 250°C. ALWAYS use a fan with PETG as it tends to cool the filament in the hot end and help with retractions. Keep your retraction speed slow at 40mm/s or less. Set your bed temperature to 50 – 70°C. For better adhesion to glass beds, you may need to apply one coat of Glue Stick.
