The most important task for me is to achieve a good finishing surface in the minimum time. I am impress for the Naca hydrofoil finishing. The linux OS for my view is the future too. So many collaboration between Prestigious Universities and Research Institutes and for security issues too. I do like see AD Linux version. Thanks HaroldL for the topic.
Mixed system may be is good solution. Traditional horizontal layers 3D Printer for the basic and finishing with the new technology.
