A lot of the parts that are printed we don’t have a printer that can print them and that printer is extremely expensive. Steve goes on the web and sends a company our stl files and they print them and ship it to us for just about what it was costing us to print them ourself. This is working out pretty good as we have no bad parts and the printer is not outdated as soon as we buy it. So I guess the best thing to do is get good at drawing on cad then send it out to get it printed
