Multi-Delta Synchronous 3D Printer System Analysis

Parallel robots are widely used in additive manufacturing (AM). In this paper, a multiple delta parallel synchronous 3D printer structure based on 3-P[2-SS] parallel mechanism is proposed. By changing the transmission ratio to drive each 3- P [2-SS] parallel mechanism, the synchronous printing of products with proportional relationship is realized. the kinematics model of the synchronous printer is established, and ADAMS simulation analysis is carried out to verify the correctness of the kinematics model, and then the workspace is obtained. The simulation result indicates that the new structure not only finishes products manufactured with certain proportion relationship, but also the work efficiency of the system is improved more than 100% at least.
