This 3D printer with a moveable arm can print on every surface. Which makes it possible to print on existing objects.
The TU Delft Robotics Institute (robotics.tudelft.nl) developed in collaboration with Océ Technologies a working prototype of a novel 3D printer using a multiple degrees of freedom robot arm combined with a high performance printing head of Océ.
The robot arm moves the printing head along complex, curved trajectories which has a number of benefits compared to the currently used 3D printers in which the printing head can only move along straight lines in a grid pattern.
This novel way of printin
g not only reduces the printing time and improves the quality of the printed surface, but it also allows printing on existing objects, with a variety of new applications such as the repair of cracks, coating, restoration, etc.
