Abstract: An additive lathe integrates the advantages of additive manufacturing (also called 3d printing) with the cylindrical motion of a lathe to reduce material waste, print times, and increase creative potential. A post-processing system allows for an improved surface finishing on parts. The additive lathe no longer prints in cartesian (X, Y, Z) coordinates as other 3D printers and instead prints using cylindrical (R, Theta, Z) coordinates. The traditional bed or build plate is replaced with a horizontal cylindrical starter bar, on which 3D printed material is deposited along and around the bar. Essentially, the additive lathe works like a conventional lathe, but in reverse. Instead of taking a cylinder and slowly removing material as the part spins, the additive lathe adds material along and around the bar iteratively building up the part. The finishing mechanism allows for the creation of a smooth outer finish on printed parts while still in the printer.
