- What is PETG good for compared with PLA?
- PETG is tougher and more heat-resistant, so it suits brackets, clips, enclosures and outdoor parts. PLA is easier to print and better for display pieces.
- Does it need a heated bed?
- Yes. PETG bonds best with a bed around 70-80°C and a nozzle around 230-250°C. A printer without a heated bed will struggle with adhesion.
- Will it fit my printer?
- The 1.75 mm diameter is the most common size and fits most modern FDM printers. Check that your printer is specified for 1.75 mm filament, not 2.85 mm.
- Why is my PETG print stringy?
- PETG oozes easily. Lower the nozzle temperature slightly, raise retraction, and dry the spool first if it has absorbed moisture.
- How should I store the spool?
- Keep it sealed with a desiccant pack. PETG absorbs moisture, which causes popping, bubbles and weak layers. Dry it before printing if it has been open for a while.
- Is it food safe or safe for outdoor use?
- PETG handles outdoor sun and rain better than PLA, but printed parts are not reliably food safe because of layer gaps. Use it for functional outdoor items, not food contact.
