As an engineer that currently uses 3D printing, most 3D printing applications have been used toward manufacturing equipment and fixing parts as opposed to 3D printing actual devices. Most items I am 3D printing are used to help fix a faulty part on the manufacturing line and this in turn helps prevent the company from having to order a new part. Machining parts for medical through CNC Machining is the closest thing to 3D printing for medical devices. As much as the field wants to move toward 3D printing medical devices, I don’t foresee machining going anywhere any time soon.
