It does sculpting, 3d tech and all that, it gets very precise

I’m not talking about sculpting. I’m talking about overhangs and other fundamental issues that 3d printers need to solve before the darn thing is printed.

I’m looking up Blender’s features, and it seems like there are features that can do this stuff (ex: docs.blender.org/manual/…/3d_print_toolbox.html), but even then…

Blender can be used to created meshes for 3D printing. Meshes exported from Blender are usually imported into a piece of software takes the mesh and “slices” it into paths that the 3D printer can execute. An example of such Slicer software is Cura.

Even in Blender’s manual, it seems like they’re suggesting you need a 2nd piece of software to do this job well.

The physical act of creating a 3d print needs to be thought of, especially in artistic designs. You will often create impossible shapes (most noticeably overhangs), especially if you’re ignorant to the whole 3d printing process. Having good software that detects these situations is… well… maybe not necessary. But it helps.
