I may at some point Michael.

Desktop stereolithography printers like the Formlabs 2 can make castable resin parts. And 3D printing services like Materialise.com can directly print metals including titanium. These techniques can certainly make complex solids that would be impossible to machine from a solid billet of metal as I do.

An inexpensive thermoplastic 3D printer like the Robo is a great tool to prototype and test ideas before committing to the more advanced methods.

My son purchased his 3D printer to make master parts from which he'll make silicon molds.

Using MoI to print 3D parts takes this program to a whole new dimension (pardon the pun :)
