Yes great stuff, 3d printers… but the performance of 3d printers is about 1/20000 Fps for most objects. It takes a while… Did you know, before the 3d printing you can put the obj model in the sim ? Read the obj into Blender, convert it with the Khronos tool and put it in your SDK project, before you actually print it… or while you print it…
(things combine, though I must admit this is not a simmers thing)
