Prototyping
Hi Eddie,
As Eric stated, It would be best to create a wax master for the ceramic dip/investment.
I own/operate a rapid prototyping firm. I can offer my services to you for the investment process. I have the following equipment... SL-250 Stereolithography, FDM (we can run polystyrene, ABS, nylon 6/6, etc.), 3D print - which by the way is set-up for investment masters (wax). We can also create soft tools for mass casting of investment masters in a wax of your choice.
If your interested, PM me for more details, file requirements, etc.
