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，以生产局部适应的特性，以及在有限元模拟和结构优化中对这种影响进行建模。在实验测试中，确定了主要的影响因素，并绘制了与建筑位置相关的图。采用了新的曝光技术和策略来操纵熔池和均匀化组分的性质。研究结果被纳入了一个与壁厚相关的材料模型，用于结构优化，这是在项目中研究的。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材料模型将用于开发薄壁结构产品开发的方法。在未来，可以加快产品开发过程，提高经济效益。在此基础上，可以为塑料的选择性激光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.
