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

该项目的目的是系统地研究薄壁部件的工艺-几何-相互作用，以产生局部适应的特性，以及在有限元模拟和结构优化中对这种效应进行建模。在实验测试中，主要的影响因素被确定并映射到过程中的建筑物位置。新的曝光技术和策略被用于操纵熔池和均匀化组件属性。研究结果被纳入一个壁厚相关的材料模型的结构优化，这是在该项目中进行调查。参与的工业合作伙伴将在项目过程中验证结果。实验结果和壁厚相关的材料模型将用于开发薄壁结构的产品开发的方法。在未来，产品开发过程可以加快，经济效益增加。基于这些发现，未来可以为塑料的选择性激光束熔化开辟新的应用领域。

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.
