Planar Four-Link Mechanism Analysis for Application in 3D Printing Machines
The aim of the paper is to present planar pantograph mechanism analysis that can be used to aid design of new mechanics for desktop 3D printers. Matlab code for inverse and forward kinematics was developed and equations are presented in this study. Theoretical accuracy of the proposed design indicate that the proposed mechanism could provide similar accuracy to 3D printers based on linear Cartesian systems, at the same time reducing complexity of the mechanics, with slight increase in the complexity of the controller software.
