Additive manufacturing or 3D printing offers new possibilities for the production of shape memory polymer actuators. In the final thesis, we designed an experiment and built a test rig for measuring the memory effect of 3D printed samples. We 3D printed an actuator with integrated heating from shape memory polymer SMP55 and electrically conductive filament Protopasta. We measured the value of the maximum force during the shape memory cycle, the time from the start of heating to the achievement of the maximum force, the ratio of shape fixity and the ratio of shape recovery and deformation during the unrestrained shape memory cycle.
