On the nature of the anisotropy of Maraging steel (1.2709) in additive manufacturing through powder bed laser-based fusion processing

• Additive manufacturing is growing rapidly as a manufacturing method. Additive manufacturing is a rapid solidification process and may, as such, generate new microstructures with an improvement of mechanical properties compared to conventional manufacturing. The repeatability and deeper understanding of properties repeatability for both mechanical and thermophysical properties are not well-established. In the current study, a complete analysis of the nature of the anisotropy is experimentally analysed to provide input for better understanding of the printing process and the resulting properties as reliability and predictability are important factors to build trust in a new manufacturing process.
