I use blender constantly to make things for 3d printing and I haven’t spent a cent on it or any plugins I use for it.
So for anyone on the fence about picking up blender and reading this comment above, no it doesn’t require hundreds of dollars of plugins to be useful. Not for every use case.
Every use-case differs. I like Blender even when they break my hobby projects every update.
OpenScad and FreeCad also works for 3D cad files. However, many people that own 3D printers will never sculpt, re-mesh, or cad up their own objects. =3
Same - I make most of my living from Blender and I occassionally use 1 or 2 paid add-ons. With the recent improvements to the compositor and the editor, it has even replaced the last piece of Adobe software I was using - After Effects - very nice feeling. I donate to Blender after every paid job too.
