Before getting into the applications of 3d printing in healthcare, I was keen on understanding the various 3d printing techniques in the market today and the advantages and disadvantages of these techniques. One very important resource that I found on the internet which helped me get into the groove is a MOOC from Deloitte University Press titled "3D Opportunity: Additive Manufacturing for Business Leaders". Being an ametuer in the 3d printing industry, I found it to be very informative. The instructor Mark Cotteleer was fantastic and has articulated the concepts quite well with sufficient examples.
Here is a link to the course
