In my current experiment, the bottom of the sphere is clipped, giving it a base to sit on, and I'm using a modifier mesh to slow down the perimeters to 15 mm/s for the bottom portion where the overhangs are the most extreme. That's my solution when printing 6 concurrently, but for...
There is still the definition of the design domain and the basic parameters of the optimization problem (loads, boundary conditions etc.). The volume restriction, as well as, the growing direction and the maximum overhang angle are defined at this point too. After variables are smoothed and ...
