  1. We are a long way from practical mass 3d metal printing of high precision items in my opinion. Yes there are certain things that can and are being done. But if you need thousands of say engine blocks a day current technology of creating and machining does the job. I want to see ISO Class 2 or ABEC Class 7 bearings being 3d printed.
