Learn how to go from KiCad 3D exports to photorealistic renders in Blender in the Hackaday Remoticon workshop by Anool:

Remoticon: KiCad to Blender > PCB renders

Those of us using KiCad for circuit board design know how useful the built-in 3D viewer and associated (rudimentary) renderer is. KiCad renderer is getting better, but if you want to get there fast, and want to create some amazing photorealistic renders of your PCB, then Blender’s the way to go. Blender can be intimidating to start with, so we’ll walk through a couple of simple steps to go from KiCad VRML export to photorealistic Blender renders.
