In the design of control system for SLM molding equipment，AMCP control platform was used as the core，the overall program，hardware design and software design were introduced in details.Introduction of the connection method between AMCP platform and peripheral components was shown in hardware design，for example，laser，galvanometer and stepper motor.Based on the SLM molding process，system configuration，Lua script and the design of HMI were introduced in the software design.By calling the API function，Lua script could read the process file and control the scanning and laser power directly，and the parsing code of the slice file was omitted.The hardware architecture of SLM molding equipment was simplified in the using of AMCP control platform as the core，and the software development work was also decreased a lot.
