I’ve never used a 3d printer before but want to get one. I have a bit experience in blender but not too much. My question is: How do you model for a 3d print? For example, if I want to print a hollow cylinder, I go into blender, create cylinder and delete the side faces. If I print this, the walls will be pretty thin. Do I have to make them bigger manually? and if I do so (extrude and scale) does my slicer (cura) automatically fill in the solid part?
I believe you can use blender to 3d model for printing but you’ll get better results with CAD software like Fusion360, FreeCAD etc.
My process is model in Fusion, export to a .3MF file, import file into prusaslicer and generate the gcode for my printer.
If I wanted to print a hollow cylinder I would create one cylinder and another that is slightly smaller, combine the 2 cylinders with a cut to hollow out the big cylinder.
