I'd be interested in any and all software for Subaru, I'm able to use the 3D printers of Nebraska Furniture, for the moment. Prior, the technology was called stereo-lithography and I used it for the biggest defense contractor in applications which did away with the expensive cost of a model shop. The wax type structure was coated with ceramics, allowed to dry and re-coated until the desired structural requirement was met. Then the wax melted out and aluminum and or the desire material was poured in. Lastly the -ceramics broken and or dipped in a chem etch tank. The technology is coming along and soon actual parts will be made as needed, thereby doing away with the need for inventories. You could in an ideal world get a more pure material. The configuration of any given part may call for the use of gate which would allow aluminum to flow into confined areas, prior to hardening, which is common in the investment casting industry. So the gates and the vibration to avoid air bubbles are concerns which I have considerable experience with. Along with the composites industry. In any case I'd like to see the models which you have and maybe looking at common models, there could be some economic feasibility and or a make consideration. I've trinkets, my name and company logo and tiny missiles which were part of engineering week trinkets given away. The strength is the material and thereby limited application, unless you use the material in a molding process, which might be worthwhile for high end parts in WRX/STI cars which have high cost due to Subaru and or other after market inventory pricing. When I look at the objects I've done, I doubt they would stand up to the hot Texas sun and at the microscopic level they seem honeycomb in nature. The casting is feasible and technology/innovation will someday replace inventory or the parts department.Thanks Frank
