Geometrical Accuracy of Flexspline Prototypes Made by FDM/MEM Methods
Materials Research Proceedings, 2023Abstract. This article presents an analysis of the geometrical accuracy of flexspline prototypes that were a component of harmonic drive. To produce the test models, a MEM (Melting and Extrusion Modeling) method was used. This additive method allows the production of elements with very complicated shapes from various polymeric materials.
