In addition, it was observed that creating Finite Element (FE) meshes was incredibly time consuming via traditional techniques. In theory, any lattice cell configuration could be added to the program provided that it can occupy a cubic volume and is able to be tessellated. Modified combined BCC and FCC removing x-y plane Modified FCC variants removing x-y, y-z, and x-z planes ![]() In its current state, the program includes the following uniform lattice types: These periodic structures are intended for use with the metallic additive manufacturing technologies of Selective Laser Melting (SLM) or Electron Beam Melting (EBM), however could be applied to a number of other additive technologies that require the input of an STL file.ĭeveloped out the apparent need for a fast and simple way to generate STL lattice structures for research purposes, the program is a part of a preliminary work in developing a much larger lattice generation capability. The Lattice Generator is a simple MatLab program that automatically generates various lattice geometries direct to STL format.
