Finding the ideal lattice properties and build parameters for additive manufacturing is often determined through trial and error. Having a reference chart readily available can save an engineer a lot of time. This past summer Renishaw PLC worked on creating that chart. Kenneth Nai, Principal Engineer at Renishaw and Loughborough University mechanical engineering intern, Tom Miller, researched the relation between lattice strut diameter and build parameters on their machines. The results help engineers using nTop Platform and Renishaw machines quickly access the ideal build parameters for best mechanical properties depending on the lattice strut diameter. The material used for this was Ti64.
