SEARCHING FOR FAVOURABLE POWDER BED FUSION SETTINGS IN SINTERING OF MARAGING STEEL MS1

Original language description

Additive manufacturing (AM), also known as 3D printing, enables the creation of complex shapes and structures virtually unattainable by classical production processes. This modern manufacturing technology includes metal additive technologies that are use metal powder for producing prototypes or parts with extraordinarily complicated internal or external structures. One of these technologies is direct metal laser sintering (DMLS), which is based on the powder bed fusion principle. This article deals with this principle and explains its mechanism and specifics, which are decisive for sintering every single layer and the parameters of all the final parts. The sintering process usually uses default parameters that are universal for a wide range of structures – from tiny pieces with thin walls to large and bulky parts. In such cases, parameters optimized for specific structures and situations are more appropriate. Such optimizations could enable the sintering of parts with better surface quality, with less deformations, more subtle support structures and even faster speeds. This article describes the available setting options, the processes happening inside powder bed fusion as well as an experiment focused on searching for suitable combinations of process parameters conducted on the EOS M290 machine using a martensite-hardenable steel called EOS MaragingSteel MS1.
