3D Data Integration in the Digital Twin for Circular Economy

Given the scarcity of resources, manufacturers of mechatronic products must enhance their Circular Economy practices. This paper addresses the challenge of geometrical digitization and digital continuity throughout all phases of a product's Life Cycle. An approach based on Digital Twins, incorporating 3D scanning data, is proposed. The comparison with initial design data enables automated quality assessment regarding appropriate Circular Economy strategies to feed back into product design. A literature review is conducted in the field of curve, surface, and geometry reconstruction of 3D point clouds. Limitations, research gaps and potential future works with a focus on R-Strategies within Circular Economy are presented.
