Interllocking/Staggered Layers for Layer Adhesion #10998

Open jaggzh opened 1 year ago

jaggzh commented 1 year ago

By printing layers with gaps, overlying layers can penetrate into the gaps, forming strong interlocking cross-layer bonds. Video: https://www.youtube.com/watch?v=qARgOYFDlHI

I have a feeling this may have a similar issue to https://github.com/prusa3d/PrusaSlicer/issues/9068 What I mean by that is that this method of printing may add so much time you're probably better off just adding 2 more perimeters to your print.

image I feel this is too optimistic - material generally solidifies too fast to flow into gaps like that, and surface tension would likely cause more gaps to appear.

I'd love to be proven wrong of course - I'm always looking for ideas to get closer to that perfect Z adhesion.

You should probably use that existing model split into layers and hack together some gcode to test it. Developers are more likely to get hooked on an idea if there is a proof of concept gcode/3mf they can test on their machine.
