Using a conventional fused deposition printer, how would you print the object? There’s no flat surface to lay on the bed without generating a lot of overhangs. That usually requires support.

[DaveMakesStuff] demonstrates a great technique for 3D printing a sphere ... interlocking parts and using vase mode ensures a support-free print that uses a minimum of filament.

In this post, I will share how to use the 3D Builder app in Windows. The app supports all-important 3D printing file formats, including STL, OBJ, PLY, WRL (VRML), and 3MF files. 3D Builder app ...
