What are the main drawbacks of SLM 3D printing technology?

Last updated on Apr 02, 2026

The main drawbacks of SLM metal printing are: the cost of SLM equipment and daily maintenance is relatively high, and the equipment has strict requirements on the working environment as a precision device; the as-printed metal parts have slight pores, and the overall mechanical properties are slightly lower than CNC machined metal parts; the support removal of metal parts is time-consuming and labor-intensive because the support material is the same as the part material.
