PETG is kind of a perfect alternative to either PLA or ABS. It is almost as easy to print as PLA, also durable and reliable as ABS. However, it can be a little demanding on printing skills. This video tutorial will show you how to handle PETG by printing LED letter with it. Have a sneak peek on our tips:

**The basics:**

- Printing temperature: 220 °C - 250 °C (keep fine tuning).
- A 60°C-80°C heated bed temperature recommended.

**Solutions to PETG adhesion problems:**

- Add a brim for a better adhesion.
- Print sticking too much? Use release agent or remove while hot.
- A textured PEI platform can do a lot.

**How to avoid oozing and stringing:**

- More Z offset for PETG.
- Slightly reducing the "Flow" in Luban.
- Reduce Initial Layer Line Width as appropriate.
- Enable "Retraction".
