This hexapod robot moves via a single motor, which spins a crankshaft that pumps fluid to the robot’s legs. Besides the motor and battery, every component is printed in a single step with no assembly required.
There are two groups in printing: direct and indirect printing. The main difference lies in the fact that the design is made from printing (direct) or printing was used in the process of creating your model (indirect). Maybe something for Printer Chat?
