SLM printing uses selective laser melting technology which melts metal powders and solidifies layer by layer until a three-dimensional part is built. During the process, the ruler in the build chamber will pave one layer of the metal powder, a high powered laser selectively fuses the powder by tracing cross-section of the part on the surface of a powder bed and then a new coat of material is applied for the next layer. The whole process is in a high vacuum chamber or full of protective gas chamber to avoid the metal powder reacts with oxygen at high temperature.

ZRapid is using a high energy and fine spot laser, The equipment can complete complex parts in a very short period time while using conventional methods that will take several weeks or even months to complete in comparison. Parts not only have precise dimension, high tensile and high density, but also excellent in mechanical properties. Mainly used for rapid production of high-precision, high quality metal parts.
