Just a few tips if you want to play with it.
- The order of the process affects the print. So it prints process 1, then 2, then 1. If you have 4 it goes 1,2,3,4, 1,2,3,4 unless some of the objects are close to the fast x/y, then sometimes goes 1,2,3,4,2,1,3,4.. It's a bit weird to control, but when you check the gcode you can change the order of the process. To do that, you need to delete a process and undo, that will move the process to the last position (this isn't explained anywhere btw).
- If you remove the autocenter option from s3d menu, the object will stay exactly on the coordinates it was designed. So you can make the object in parts (even if they intersect). But s3d can't have 1 object badly done (it fixes much worse than cura). So if you want to make a complex object fast, it's better to export each stl in parts, then s3d can handle it as a group (even if they intersect) and they print fine. Umm this was badly explain... Each stl must be perfect, but if you drop x4 stl that are 1 object, if each part has intersections with each other it's just fine when group.
- You can make floating parts, for example a top layer of 0.2 height, over a cube. Then you assign a process to that flat layer so it prints an aditional layer over the object. This way you can play with textures, and make effects like this:
As soon you get use to how s3d thinks you can use some options to get a clean print.
Also, for fast prints, it's better to avoid bolean objects and just export each part on an stl, then drop them to s3d (with autocenter off) and group them.
