Early Adventures in 3D Printing
New technology excites me. Always. In my experience, learning and understanding new technology can only ever have positive results. It is never a hindrance to education or career (unless you make it so by misapplying what you've learned or prematurely forcing new technologies where they're not helpful, so don't do that).
I've been following the 3D Printing phenomenon for years. I continue to marvel at the number of applications people find for it. So why not give it a try, even if I can think of no personal use case for it today?
That was my thinking a month ago.
