* As a filament type, PETG is terrible at things like steep overhangs and bridging. This includes you might need just a bit more top surface over infill to get a smooth outer layer. (Or just use a slightly higher infill %.) | * As a filament type, PETG is terrible at things like steep overhangs and bridging.

This has a lot to so with how all PETG is "stringy". (Some makes/brands are worse than others.) So as the hot nozzle moves through any spiderweb thin strands between printed parts, PETG filament builds up on the nozzle. (And eventually may drop onto the print, as a possibly print ruining blob of plastic.) For that reason, any print that could be described as a "highly shaped bock of plastic" should work well. But prints where the head constantly moves over open air -- with no plastic under the nozzle & creating many strands -- are more likely to fail. | ||
* These settings use a 0.35mm line width out of a 0.4mm nozzle, '''instead''' of all the other overlaps which would also contribute to PETG trying to build up on the outside of the nozzle. | * These settings use a 0.35mm line width out of a 0.4mm nozzle, '''instead''' of all the other overlaps which would also contribute to PETG trying to build up on the outside of the nozzle. | ||
