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 […]

  The additive manufacturing contractor making Delcam’s parts did not want to produce all four parts in the same build, even if those parts did all fit on the plate. The reason: AM involves considerable uncertainty related to residual stress and other effects as the part is forming. Better to build just one part first, […]

  In the manufacturing process for any AM part, questions about the steps after additive have to be faced at once. For example, how will the part be removed from the build plate after the additive cycle is done? And what features will be left for subtractive processing (machining) instead of being completed additively? These questions are […]

  Not all of the design ingenuity in additive goes toward features of the final part. Some goes to forms destined to be cut away and discarded. In additive, every part feature that projects horizontally from the part is a feature in danger of collapsing as this form is taking shape in one minute layer […]
