| Abstract Scope |
SRNL is working with other national laboratories and sites to evaluate the manufacturability of the Electron Beam Powder Bed Fusion Process. A variety of lattice types have been printed and the ease of cleaning is being investigated. The desired lattice size is a 4 mm octet truss configuration. This lattice has been printed and challenges with cleaning it have been realized. The initial results have led to modifying the cell size to determine the scale at which the cells can be easily cleaned out. A method has been developed but challenges remain. This presentation will describe the printing process used, design of the cells, the results of the cleaning efforts, and the quasi-static property testing results. |
