Someone just asked the question what is 3d printing? I was going to respond, explaining how it was an additive process not a subtractive process and give examples and I realised I had only given examples of subtractive processes in the past.
This got me thinking about additive processes what are the current ones in use other than 3d printing?
I could only think of one being injection molding.
That got me to thinking about the main problem with injection molding being the setup cost in creating the initial mould. I realised that creating the mould for an injection molding machine would be an ideal use of 3d printing.
Your comments, criticisms and observations would be most welcome.
