The small hairy creatures with the eight legs have a frightening or at least frightening effect for many people. Spinners, on the other hand, can provide practical works of art. These even use steel. From the year after next, industrial robots will be used in Amsterdam to build pedestrian bridges over the Dutch rivers - completely autonomously.

Behind the filigree composite piece are the heads of 3D printers that output the hot raw material, which becomes solid in the air high above the water and serves as a base for many pedestrians. If one often sees the individual layers of static print objects, the strands of the bridge are much more delicate and printed in a shorter time, thus avoiding annoying transitions.

The trip to Amsterdam should then be booked on a long-term basis so that you can experience first hand how the calculation of the movements in free space is implemented.
