Background

The Selective Laser Melting (SLM) technique is a technique of directly irradiating metal powder with a high-energy Laser beam to rapidly melt and cool, solidify and form the metal powder, and it can be applied to a single metal powder or a mixed metal powder. The SLM technology overcomes the troubles caused by manufacturing metal parts with complex shapes by the traditional technology, and can directly form metal parts which are nearly fully compact and have good mechanical properties.

In order to make the apparatus more versatile, commercial SLM forming apparatuses are usually configured with relatively large forming and material cylinders, which can meet the requirements of both large-size forming or simultaneous forming of multiple small-size pieces, and also can be used for small-size single piece forming, which requires more raw material powder due to the large forming and material cylinder sizes. However, for some experimental studies, such as research in colleges and universities or research institutes, the demand of large-sized forming cylinders and material cylinders for powder is extremely large, SLM powder is expensive, and research cost is high and burdensome. Therefore, an SLM apparatus is proposed that reduces the size of the forming cylinder and the material cylinder.
