COMPARISON OF SELECTIVE LASER MELTING OF 18NI MARAGING STEEL BY PXL AND M2 CUSING

Abstract

This study compares 18Ni maraging steel processing on two competitive SLM machines, PXL and M2 Cusing. For the production of samples, powder material from original machine supplier was used on each machine separately. Process parameters for the production of small thin-walled parts were set individually on each machine according the recommendation of the device manufacturer. The basic mechanical properties of the produced materials were determined using tensile tests and hardness measurement. Metallographic and fractographic analyses were conducted by means of a lightand scanning electron microscopes. In comparison to M2 Cusing, higher relative density achieving 99.9% in the volume of material, was measured on the thin walled samples of PXL. The reason is probably higher energy density during material processing. As a consequence, the specimens from PXL had slightly better mechanical properties.
