Working with PETG for the first time.
Improvement in quality I decided to try 3D printing with PETG since PLA has limitations when it comes to heat resistance and strength. People in 3D printing forums suggested PETG and ABS, but they warned me that PETG is difficult to print. I had scoured the internet trying to find out what perfect 3D printing profiles would result in good quality prints. Almost all of them emphasised that a hot-bed was needed. Now I have two 3D printers, one with a hot bed and one without. My 3D printer with a hot bed has a Bowden Tube, and some people warned that PETG does get stuck in Bowden Tubes sometimes, which scared me a little bit. So, for my first PETG filament test print, I used a 3D printer with a direct drive extruder but no hot bed. I was initially scared that it wouldn't stick. But my first test print went well. The print was a 3 mm cube, and the resulting brim stuck well. Next, I decided to print a more complex image to see how it would fare. I had set the recommended PETG profiles;
