Abstract
3D printing is a relatively new and quite attractive form of production, especially for complex parts. In this work, the SLM technology was used to prepare a magnesium alloy WE43 (Mg-4Y-3RE-Zr), a promising material for biodegradable implants. The aim of this study was to map the microstructure and mechanical properties of WE43 produced by SLM and compare it with conventional casting. Microstructure and chemical composition were studied using scanning electron microscopy (SEM), energy dispersive X-ray spectrometry (EDS) and transmission electron microscopy (TEM). To examine mechanical properties, hardness measurement, compression tests and three-point flexural tests were carried out.
