Abstract
SLM technology is gaining more and more distribution and application in many industries after it was possible to ensure a sufficiently high density of products. The technological parameters of the process significantly affect the quality of the products. Purpose: establishment of rational printing modes of volumetric samples, with a working thickness of the 316L powder layer of 40 microns to achieve a density of volumetric samples of 99.9%. Volumetric samples (10 × 10 × 3 mm) were produced on an Alfa-150 3D printer manufactured by ALT Ukraine LLC. Experimental manufacturing modes: power - 195 W, speed varied in the range of 800...900 mm/s with a step of 100 mm/s, distance between tracks – 0,08...0,11 mm with a step of 0,01 mm. Determination of the density of metal samples was carried out by the metallographic method on an optical microscope CarlZeiss AxioVert 200M mat. It was established that with the thickness of the applied layer of 40 μm metal powder of steel 316L, at a scanning speed of 800 mm/s and a distance between tracks of 0,08 mm during the production of volumetric samples using SLM technology, their density is 99,98%.
