Parametric analysis of 1.2709 maraging steel manufactured by LPBF

EasyChair Preprint 1061

Abstract

The lack of standardisation in handling LPBF processes (Laser Powder Bed Fusion) requires the creation of a material-specific knowledge base. Resulting material and structural properties as a function of variable process parameters have to be investigated in the handling of new powder materials based on steel.
The material 1.2709 is one of the promising powder materials used in laser additive production and serves as the experimental material for this project work. In connection with an Nd:YAG laser system of the, the quality-relevant process parameters scanning speed, laser power and line offset are quantified in a simplified test setup. Additionally the influence of an angular offset on the component quality is investigated.
