Creality Ender 3 & PETG Filament – How to Achieve Success

3D printing PETG on the Ender 3 can seem daunting, but with the right bed adhesion measures, you can step into this new material with ease:

Bed Temperature

Due to the high melting temperature of PETG, we recommend setting your Ender 3’s bed temperature to between 50 and 60 °C.

Build Surface 

The standard Ender 3 build surface, BuildTak, is the ideal surface for printing PETG with the Ender 3. This material will allow you to have excellent adhesion while providing a more natural way to remove the print due to its flexibility. But be warned: An initial layer height that is too small can cause PETG to fuse to the print bed, making it easy to damage.

The Ender 3 Pro comes with a glass build plate, which should be approached carefully. PETG is notorious for sticking to the glass so well that it fuses to it. This fusing can be so strong that it removes chunks out of the glass bed, permanently damaging it. If you choose to use glass, use a thin layer of hairspray, glue stick, or specialty bed adhesive.

Covering the Ender 3’s print bed with blue painter’s tape is the best and easiest way to get PETG to have a secure bed adhesion as well as ease of removability. We recommend this method as your default.

Another good option is Kapton tape. This tape will give you the same benefits of using blue painter’s tape, but might not have the same amount of adhesion.

Initial Layer Height

Simply put, PETG is different from ABS and PLA: We recommend backing away from your print bed in 0.02-mm increments until you get the initial layer height just right.
