Cliff Smyth, experienced 3D printing enthusiast and author, thought it was important to write the book on some of the more simple rules regarding 3D printing that can actually make or break a print—literally. He focused here on infill and shell parameters and how they affect the durability of a 3D print, with more infill generally resulting in higher strength, and less infill creating more flexible parts.
