Elon recently noted that Raptor (unlike SuperDraco) won't be fully 3D-printed. It will have 3D-printed parts, but most of the engine will be machined. I guess for a larger engine the things you mentioned have to be more tightly controlled to be able to print the whole engine. Might also be a cost issue as size increases, I guess.
