Optimizing PETG Layer Bonding Strength in Cura
I'm working on some small car interior trim clips that have to rely on layer to layer bonding strength. Filament is Inland PETG, printer is stock Ender 3 with Capricorn tubing.
When I run just one test print it functions well, but with the same settings when I run 21 they all break along the layers at about the same high stress point. If I set up Cura to run then in "One at A Time" mode I can only fit 4 on the bed at a time, and I'd like to print much larger groups.
I'm printing at 0.2mm, 17.5 mm/s, 255F / 70F, and pretty much all of the part is made of walls as it's pretty small (about 0.750" x 0.750").
What else can I do to optimize the layer to layer bond of the PETG? Thanks!
