Process strategies for the production of thin-walled components during selective laser beam melting of plastics (T03#)

• Subject Area: Plastics Engineering
• Term: from 2021 to 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 61375930

The aim of the project is the systematic investigation of the process-geometry-interaction of thin-walled components for the production of locally adapted properties as well as the modeling of this effect in finite element simulations and structural optimization. In experimental tests, the main influencing factors are identified and mapped in relation to the building position in the process. New exposure technologies and strategies are used to manipulate the melting pool and homogenize component properties. The findings are incorporated into a wall thickness dependent material model for structural optimization, which is investigated in the project. The participating industrial partners will validate the results over the course of the project. The experimental findings and the wall thickness dependent material model will be used to develop a methodology for the product development of thin-walled structures. In the future, the product development process can be accelerated, and the economic efficiency increased. Based on these findings, new application areas for the selective laser beam melting of plastics can be opened up in the future.
