Designing for 3D printing is not the same as designing for injection moulding.
The same part may need different design choices depending on how it will be made.
For injection moulding, you need to think about things like draft angles, ribs, wall thickness, shrinkage and how the part comes out of the mould.
For 3D printing, the focus is different: print orientation, support material, layer direction, overhangs, surface finish and material behaviour.
Neither process is simply “better” — they just have different rules.
That’s why CAD design matters.
A good model is not just a shape on screen. It should be designed around the process, the material and the job the part needs to do.
