Wire EDM is the process of choice for cutting metal AM parts away from their build plates. This precise cutting operation leaves a clean, square surface. However, EDM through the large base of the manifold part was slow. Like the additive cycle, the EDM cycle stretched through many hours to become a major contributor to lead time. Delcam engineers had added 2 mm of stock to allow clearance for EDM, but they came to recognize that they should instead have added 5 mm of stock to allow for bandsawing. Cutting the parts with a saw would be much faster, and the lack of precision would be no loss in this case because the surface was going to be CNC machined anyway. Unfortunately, the second additive build was underway by the time this realization came, so it was too late to add the extra stock.
