Problems with removing support structure (PETG, picture attached)
Hello Prusa community,
I'm quite new to printing, but so far my prints are running quite well. I have just one problem, which I couldn't solve by myself so far:
For the part I'm printing at the moment, I need to place support structure on the part itself. The Slicer puts two layers between the part and the support structure by default, which I find nearly impossible to remove. Any suggestions how to print the support and the removing it easier?
Thanks a lot
Check the Z separation. Prusa Slicer defaults to .1, which is for soluble supports.
Change it to .2 (removable). And leave a little gap between X Y pieces. Only support overhead.
It will always be hard to get perfectly clean separation...
I use no interface layers when supporting flat surfaces, and set contact Z to 0.01 mm (zero dot zero one). This allows direct support and minimizes bridging droop and creates a flat underside. I also adjust support spacing and angle to best support the direction of the bridging filament - 2 mm is sometimes too close together. This part I used 3.9 mm spacing.
I printed [this]( https://www.thingiverse.com/thing:3232756 ) with 0.4mm Contact Z distance and the result was perfection.
I'm not sure why 0.1 is the default, I mean, by default not everyone is trying soluble support from the begging, at least should be a warning in the app.
