NEED FOR SUPPORT STRUCTURES DEPENDING ON OVERHANG SIZE

Abstract

This paper is focused on 3D printing of metal parts and the limitations of this method. There are numerous methods currently used for 3D printing, for example, DMLS, SLS, CLADDING, etc. This paper is limited to 3D printing using DMLS (Direct Metal Laser Sintering). The method works with metal powder, which is applied to a building platform in thin layers. The shape of a part is sintered using a laser beam in each layer. The part is built layer by layer. The material used for the experiment was maraging steel 1.2709. Laser sintering was undertaken using the EOSINT M 290. We used the process parameters recommended for this powder by the equipment manufacturer. The measurements were carried out on a Blickle Multicheck PC500 microscope. The goal of the experiment was to find the size of the overhang which does not show signs of degradation of the geometry of the overhang.
