Abstract: In order to solve the current problem that some printed pieces with cantilever and cavity structures but not allowed to add internal support can not be printed, a type of 3D printer with reversible working platform was designed. The structure composition and working principle were introduced. Through kinematic analysis of the system model, the kinematic positive and inverse solutions of the working platform mechanism were obtained, which provide the basis for the velocity analysis and motion control of the 3D printer mechanism. The simulation model was established using ANSYS simulation software, the stress and modal analysis of the structure of the working platform and the nozzle were obtained, which verify the feasibility of the design scheme. Consequently, the possibility that the working platform can be turned over was achieved and the non-support surface structure can be printed.

Key words: mechanical design, 3D printing, structure analysis, space trajectory planning, model simulation
