Research of Control System for Mask Projection Stereolithography with Raspberry Pi

Abstract

To reduce the space and cost of the control system of Mask Projection Stereolithography Apparatus (MPSLA), the control system of MPSLA based on Raspberry Pi is designed and implemented. The system with Raspberry Pi as the control core, Linux as the operation system, realizes the projection control of mask image and the motion control of platform by using Python program. When Raspberry Pi connects to the network via the Ethernet port, remote control function of the control system has been achieved for MPSLA with VNC. The control system provides MPSLA with some telecontrol function, such as Remote login, File remote transfer via FileZilla and Remote monitoring. The novel control system distinctly reduces the space and the cost of MPSLA.
