This video shows an example use of 3D printing–using a 3D printer to make a plastic mold for a soft robot gripper. The printer feeds a spool of ABS plastic filament into a heated nozzle. This melts the plastic, and it is extruded through a narrow hole at the tip of the nozzle onto a build platform. When it comes in contact with the platform, the plastic quickly cools and solidifies. The nozzle continually extrudes material in new layers to gradually build up a three-dimensional part. The entire printing process took about 3.5 hours, but the video is sped up so you can see the whole thing in just a couple minutes.
