Let’s get into the first of a brace of posts on the subject of 3D printing. This time around the block, we’re going to talk about something that I get asked about a lot and something I’ve often seen being misconstrued in more general media – namely, the difference between 3D printing and Additive Manufacturing.
It used to be much easier. Most 3D printing technologies were used for rapid prototyping. The creation early stage product mock-ups, of concept models – essentially supporting the design and engineering process. They were used to mimic the results of more traditional manufacturing processes, such as machining, casting, injection molding, etc, etc.
