Intro to 3D Printing

Learn how a 3D printer turns plastic into a part. You meet a real printer in 3D, learn the plastics it melts, write your first print, work out how much plastic a line needs, print a square, see what a slicer adds, read a real print and fix one that would fail. Every print runs in 3D as you edit it. For anyone 13 and up. Free.
