Investment Casting with 3D Printing

What if you have a part design with very complex geometry (e.g. undercuts) that cannot easily be machined? Directly 3D printing in metal is not a great option due to the high cost, but fortunately it is possible to print the net-shape part in plastic, then create molds for investment casting by burnout! We are working with researchers at Auburn University to experiment with this technique, and would love to try it for customers that need complex, optimized geometries produced in metal.  (You will know if you need this).  It is a great companion to our engineering design services that can use topology optimization among other techniques!
