... be fabricated in situ, without assembly, inside AM machines. This includes parts with working mechanisms ( Fig. 11 ) as well as parts with embedded devices, such as a shrouded impeller. Topological optimization: A part can be made strong enough while using the least amount of material. Fig. 11...

...) Optical micrograph showing intergranular crack path and minor branching. Original magnification: 40× One of the cracks was forced open in the laboratory to reveal the topology of the crack surfaces. The crack exhibited dark discoloration from in-service oxidation and an intergranular crack path...

... with some designs adds another source of error that can create a problem down the road. If the manufacturing process is not optimized, defects can arise. For example, molded-in stresses can cause deformation in a product or even create an internal stress, contributing to a future failure. Improper...
