Hi, I want to start making parts using Carbon and Kevlar. Initial requirement is for a duct. I am contemplating a 3D printed investment mould using ABS or PLA. I have seen it is possible but cannot find any videos showing the process.

The parts will not be massive, perhaps 500mm cube. I would like to be able to start on a relatively low budget so anyone with existing facilities who would be able to help out in the locality I would appreciate it.
