Direct metal laser melting (DMLM) is an additive manufacturing process that uses lasers to melt ultra-thin layers of metal powder to build a three-dimensional object. Objects are built from an .stl file generated from CAD (computer-aided design) data. Those .stl files will be converted through our machine software in slice-files, which are actually used for the build process. The use of a laser to selectively melt thin layers of tiny particles yields objects exhibiting fine, dense and homogeneous characteristics.
The DMLM process begins with a recoater spreading a thin layer of metal powder on the print bed. Next, the slice-file generated via our software lays down the scan paths that controls the exposure of the laser to create a cross-section of the object by completely melting metal particles. The print bed is then lowered so the process can be repeated to create the next object layer. After all layers are printed, the excess unmelted powder is brushed, blown or blasted away. The object typically requires little, if any, finishing.
