MODELING A 3D PRINTING OPERATION USING THE ROBODK SOFTWARE ENVIRONMENT AND A ROBOT T MANIPULATOR

Abstract

The article discusses the methodology for modeling and simulating the 3D printing process using a pellet extruder within the RoboDK software environment. The use of robotic systems in production processes allows for increased material deposition accuracy, reduced costs, and a minimized likelihood of errors. One of the key aspects of implementing such technologies is preliminary digital testing, which enables the optimization of manipulator motion trajectory parameters and the verification of their effectiveness without the need for physical intervention in the equipment. As part of the study, an algorithm for creating a virtual environment in RoboDK was implemented, including the import of CAD models, setting up coordinate systems, tool calibration, and the construction of an optimal multi-axis 3D printing trajectory. The use of modeling makes it possible to assess potential collisions, determine the permissible ranges of manipulator motion, and adapt the polymer material extrusion parameters according to the specific geometry of the product. The performed simulation allowed for the determination of optimal operating modes for the extrusion system, as well as the adjustment of control parameters to minimize errors. The results obtained demonstrate the feasibility of using RoboDK for preliminary testing and debugging of robotic 3D printing technological processes. The use of simulation significantly reduces the time for development and setup of the production process, decreases the risk of errors, and improves the quality of the final product. The proposed approach can be used to improve control algorithms for robotic manipulators in other manufacturing sectors that require high precision and operational stability.
