Due to the high requirement on the accuracy and stability, the control system of the scanning selective laser melting forming device is always a hot research at home and abroad. Based on the development demand of new SLM materials such as ceramic, composite and others, this issue developed a SLM forming control software. The software is compatible with the forming equipment of our lab. The main research work including: (1) The SLM forming principle, the working principle of vibrating mirror system and need of the conventional ways of scanning for new materials research’s need were mastered; (2) We did the requirement analysis for the SLM control software, planned out the function modules, and designed the program interface; (3) We coded according to the designed interface, realized the function of software modules respectively, and then realized the function of the entire program required of all; (4) We did a connection test for the program and the forming device, and used a simple experiment to verify the validity of this software.
