Abstract

The invention discloses continuous printing SLM equipment. The continuous printing SLM equipment comprises a shell, a powder feeding device, a powder spreading device and a printing device; the shell comprises an upper box body and a lower box body, a powder feeding device is arranged on the rear side of the upper box body, an opening is formed in the front side of the upper box body, a printing device is arranged in the lower box body, and a powder spreading device is arranged above the printing device. The SLM equipment for continuous printing is simple in structure and convenient to use, through cooperative arrangement of the shell, the powder feeding device, the powder laying device and the printing device, on the premise that the laser transmitter is not moved, movement of the basic shaft and the powder laying trolley is achieved, and therefore the printing range in the printing process is widened, and large 3D parts can be conveniently printed.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to a continuous printing SLM device. Background technique [0002] SLM (Selective Laser Melting) technology uses high-energy laser beams to irradiate metal powder to make it melt rapidly and cool and solidify into shape. Metal powder materials are accumulated layer by layer to create a three-dimensional entity. SLM technology combines advanced science and technology such as new material technology, laser technology, and digital technology. It not only has fast forming speed, high material utilization rate, and high degree of intelligence, but also can manufacture products with complex structures. SLM technology has broad application prospects in aerospace, medical equipment, automobile and military fields; [0003] At present, the printing space of SLM equipment is limited, and the base axis cannot be moved, making it difficult to print large 3D parts. [0004] Base...
