The SLM 420D 3D printer utilizes Selective Laser Melting (SLM) technology, a process that involves melting metal powders and solidifying them layer by layer to create three-dimensional parts. Within the build chamber, a metal powder layer is evenly spread by a roller. A high-powered laser selectively fuses the powder by tracing the part's cross-section on the powder bed's surface. Subsequently, a new layer of material is applied for the next stage. To prevent unwanted reactions between the metal powder and oxygen at high temperatures, the entire process takes place in a controlled environment, typically within a high vacuum or a chamber filled with protective gas.
