Parallel manipulator robots are widely used in a large number of applications because they provide important advantages in terms of superior speeds and accelerations, high stiffness and good dynamic performance. In additive manufacturing (AM), this kind of kinematic structures is being increasingly explored to develop new curved and multi-directional fabrication strategies.Based on this application, this work presents the design and dimensional synthesis of a new structure of the Linear Delta parallel robot for AM (3D printing). The new structure uses an innovative concept of Delta mechanism with single legs and rotational joints, which consists of twelve links (three parallel single legs), three prismatic joints and eleven revolute joints. A particular feature of the proposed mechanism is that it contains a joint common to all the kinematic chains instead of a mobile platform as in the conventional Linear Delta structures. Mobility analysis, inverse and direct kinematics, and a study of dimensional synthesis are described in detail. A method of efficient optimization based on genetic algorithms is used to find the minimum dimensional parameters of the robot, considering the maximization of the useful workspace as the main performance index. In order to validate the proposal, a prototype of the robot was built. Capability and geometric deviations analysis was carried out for three test parts resulting in a 0.3-mm deviation/error within a confidence interval of 99.7%.

“…As a result, additive manufacturing experts must devote a significant amount of time and effort to this sector. Some initiatives, such as [14][15][16], have been made to adopt the STEP-NC standard for additive manufacturing. Currently, work is underway to develop a STEP-NC-based CNC system for 3D printing, which will be released soon.…”

Development of virtual component-based STEP-compliant CNC system

Future manufacturing systems will need to be versatile, intelligent, adaptable, and long-lasting. Current systems cannot meet those criteria due to limitations in the data interface model and controller architecture. The Standard for the Exchange of Product Data-Numeric Control (STEP-NC) data interface model and open architecture control technology have the potential to enable the features of the next-generation manufacturing system. Three different programming approaches were used to implement the STEP-NC technology: indirect, interpreted and adapted. This study used open-architecture control, virtual component, and microcontroller technologies to develop an interpreted STEP-NC programming approach-based CNC system. The computer, Arduino microcontrollers, and custom boards were used to connect the system to the three-axis CNC milling machine. The STEP-NC implementation, on the other hand, has been done using a virtual component technology-based software system. The STEP-NC Part 21 programme file is read, parsed, interpreted, simulated, managed, and executed by the developed software. The paper's content discusses system development as well as experimental validation. Finally, the study's future directions are highlighted.

“…However, Standard for the Exchange of Product Model Data Compliant Numeric Control (STEP-NC) guarantees the transparency among design and manufacturing, which will resolve the information loss issue of G code and will enable the bidirectional informational flow. This transparency of data between design and manufacturing has built an enormous platform to facilitate the interoperability in the manufacturing system [8].…”
