Stitch the layers using injection molded rivets #5150

Open Harvie opened 1 year ago

Hello guys, i have this idea to increase layer adhesion and prevent delamination. Basicaly you create cavity which is used as injection mold to create "rivet" bonding several layers together. This will probably need to increase temperature so the filament flows more smoothly into such mold. What do you think?

Viable injection depth is obviously limited, but we can use interleaved pattern like this:

It might be even possible to inject butterfly shaped rivets to increase hold. Also even for perimeters not straight in Z direction it might be possible to get injected:

Although the injection process might require the rivet hole to be vented in some way for the air to escape:

Maybe even micro rivets (only joining two adjacent layers) might be viable, since they would eliminate need for venting and would be well suited for complex geometry while still simple to implement. But it would obviously come with reduced length of polymer chains in Z direction...
