* For best results printing PETG, '''do not use the Filament Fan'''. (Print with the Hotend Heatsink Fan '''only'''.) When the Filament Fan is used, expect layer separation problems. When printed without using a Filament Fan, PETG has '''exceptional''' layer bonding. | * For best results printing PETG, '''do not use the Filament Fan'''.

* | * As the head moves through spiderweb thin strands between printed parts, PETG filament build-up on the '''outside''' of the printhead. Despite this, any print that could be described as a "highly shaped bock of plastic" will probably work. But for prints where the head constantly moves over open air (no plastic under the head), the melted PETG dropping off the outside of the printhead will probably cause that print to fail. | ||
* To print with PETG, start with a '''clean''' nozzle; and the 1st layer (inside the Brim) needs to be perfect. | * To print with PETG, start with a '''clean''' nozzle; and the 1st layer (inside the Brim) needs to be perfect. | ||
* There are suggestions on the Internet about MG Chemicals PETG is brittle compared to other PETG filaments. So anything that would be "fragile" (too easy to break) when printed with PLA, could also be "fragile" when printed with this PETG. | * There are suggestions on the Internet about MG Chemicals PETG is brittle compared to other PETG filaments.
