The metal 3D printer INFINITY makes a component size of up to 50x50x50 cm possible. Separate trolleys are either way driven into the machine as powder tank or build area. The machine is monitored and controlled through the five monitors that are integrated into the sliding door. The User interface, that has especially been developed for the machine, enables the user to monitor the clearly arranged figures, to closely follow each step and to manipulate various parameters at any time. The innovation of the machine is reflected in the modern design of the machine and the interface.
