Development of Software Tool for Cellular Structure Integration for Additive Manufacturing

Abstract

Cellular structure is one of the solutions for producing parts in a more resource efficient way by reduction of material and time used. Recent advances in Additive Manufacturing (AM) have enabled these complex structures to be built while it is almost impossible by subtractive manufacturing. However, modelling process is resource intensive and time consuming due the geometrical complexity. This article presents development of a software tool for rapidly modelling the structures with prefabrication hybrid geometric modelling (P-HGM) method based on a hybrid B-Rep approach. The structure will be integrated to the specified volume in the base 3D model with polygonal approach. Open-source libraries, including OpenCascade Technology (OCCT) and Visualization Toolkits (VTK), are used.
