Surface Analysis and Digitization of Components Manufactured by SLM and ADAM Additive Technologies

The presented article focuses on the analysis of the components manufactured by different additive technologies and their reverse digitization. Sintered components were manufactured by Selective Laser Melting (SLM) and Atomic Diffusion Additive Manufacturing (ADAM) technologies. ADAM can be classified as indirect additive production using fibre of metal powder bound in a plastic matrix. SLM method works on the basis of selective bonding of metal powder using the thermal energy of the laser beam. The components were manufactured from anti-corrosion materials 17-4 PH and 316L-0407. In the experiment, parameters such as dimensional and shape accuracy were verified using laser scanning. Next, the roughness of the printed surfaces was measured on an Alicona Infinite Focus 5G optical measuring device. The dimensional accuracy of the ADAM process was evaluated using ISO IT grades. The accuracy of ADAM technology achieves the IT13 grade that is comparable to that of traditional processes for the production of semi-finished metal parts.
