We wanted to make an engineering resin that is precise, high-resolution non-brittle, low shrinkage, and warping, and still easy to print and it led us to develop Build. The best unique feature of Build is that it is tappable by screw and this is possible because Build has the unique combination of hardness, and flexibility to handle the tapping process without cracking while preserving the grooves on the tapped holes. It is an excellent resin for making fitted parts, like casings for electronics.
