Enter SLM device；2, SLM forming parameters such as laser power, scanning speed, sweep span etc. and scanning are selected according to material
Strategy；3, one layer of metal powder is spread with scraper on substrate, and is passed through inert gas toward equipment, until oxygen content is lower than specified
Value；4, laser starting transmitting laser, the selective melting of powder is completed according to planning parameters of scanning paths；5, substrate declines a thickness
Distance, scraper return to initial position (unidirectional) or directly (two-way) progress second layer powdering.The above steps are repeated until part
Forming terminates.6, it pickup and is post-processed.
From the forming process of SLM technology it can be found that SLM forming efficiency, which removes, is excited optical power, scanning speed, powder bed
It outside the effects of process parameters such as thickness, scanning line length, is largely influenced, and part is higher, is shaped by the powdering process waiting time
The number of plies is more, and powdering number is then more, and powdering duration is longer, and entire part machining period is caused to lengthen, and forming efficiency is lower.And
