The industrial robotic arm performs the function of a 3D printer designed to make car parts. The material with which it prints is metal, and the way of building the form enhances the physical properties of the material without changing their chemical composition. The shape of the product is as light and clean as possible, with covers providing access to the internal parts of the robot in the event that repair work is required. There are indicators on the outside of the covers that make the connection between man and machine. They signal the status of the robot. The choice of product colors are neutral in order to read the colors of the indicators well, resulting in a safe and unencumbered operation.
