Supra, Yes, investment casting has been around for thousands of years. But the difference between using metal and silicone is far more significant than your casual dismissal would imply. In the investment casting process, the heat of the molten metal cause the 'burn out' of the wax part... And that wax part is a positive. We're 3D printing wax tooling, and printing the negative. Our tooling is printed as a single part, very different than normal silicone molds with multiple parts and bucks, which yield partlines & flashing that must be removed. Our process has no part lines, hence no flashing, and this is only technologically possible due to printing, as the sinclastic geometries would be impossible in any other silicone tool that was not printed and then dissolved or melted. You are correct, there is a business process there- but the manufacturing process is novel. Oh and trust me on the metals bit- I was the lead tooling and mechanical designer for the team that built this out of stainless steel: http://www.nileguide.com/desti...
