One of the great things about 3D printing is that you can print an entire model in one go. The typical example is the fully assembled “print-in-place” ball bearing as shown in the image above. This is printed in one go, no assembly required. However, the tolerances are pretty small which requires a well-tuned 3D printer. In this article, I describe how I tune my machine for perfect fit.
Over the Christmas break I built a RepRap 3D printer. Everything went well until it was finished. The information on getting started with actual printing is very fragmented and all over the place. So here’s a short guide for any budding RepRappers who can’t wait to get started.
