“(USCS units) 3D Printing is used to fabricate a prototype part whose total volume = 1.17 in^3, height = 1.22 in and base area = 1.72 in^2. The printing head is 5 in wide and sweeps across the 10-in worktable in 3 sec for each layer. Repositioning the worktable height, recoating powders, and returning the printing head for the next layer take 13 sec. Layer thickness = 0.005 in. Compute an estimate for the time required to build the part. Ignore setup time. (Answer in hours)”
