GigTank's Demo Day - Sevel 3D Printing Firms Show off What they Have

GigTank's Demo Day recently took place, featuring many 3D Printing companies looking to raise funding in order to jump start their start-ups. 3D Ops, a company that is helping surgeons create 3D models prior to surgery, that they can then operate on, as well as Feetz, a company I have covered in the past, were on hand to demo their business plans in front of Angel Investors. 3D Ops was looking to raise the most funding ($2 million).
