I grew up learning organic modeling in blender and ever since I got a 3D printer, it’s just been so easy to make things with it as opposed to learning CAD. I’m getting better thanks to OnShape and FreeCAD 1.0 but I keep finding myself going back to blender because “it just works” once you understand how to setup scaling and snapping for manipulating vertices. Basically just setup your world measurements to metric and scale it to 0.001 and then every unit will be 1mm (helps me work within the 250^3mm space of my print bed, mentally) and export as stl.
There’s even a 3D printer toolbox add on that lets you analyze and fix problems like manifold edges and additional mesh tools like manifold extrude that speed up the process for good quality parts. CAD’s biggest advantage is the non linear history editing which is super powerful but you can definitely do non-destructive editing in blender using modifiers that only get applied at export time so you even have a functional equivalent if you’re organized and plan ahead a little.
I guess what I’m saying is, blender is amazing software and absolutely capable as a workhorse for 3D printing. You’re right that the multi-digit costing proprietary software is leagues better for designing digital parts and assemblies but blender is extremely flexible and not just for the more artistic side of things, you can make extremely technical parts with blender.
Literally none of what that person commented with was a thought or a feeling. It was an actual fact, with proof.
