4D printing of magnetic driving actuators for heat management

Abstract

4-dimensional (4D) printing is the next advancement after 3-dimensional (3D) printing. Instead of a rigid shape of the 3D printed that are not programmed to change shape, 4D printing is capable of printing a part that are programmed to change its shape with stimuli such as heat, moisture or magnets to name a few. This phenomenon can also be known as Shape Memory Effect and the material used for fabrication is Shape Memory Materials. This method can be applied to various industries such as robotics, medial and design.

To formulate a new Shape Memory Material, it is important to characterize the materials used. For this project, composite materials will be use. Materials included are a photopolymer resin, Carbon Nanotubes, and Iron powders. The materials will be mixed to form structures and samples followed by experiments that will characterize the composite and the materials. Properties that will be studied are the conductivity, electrothermal and magnetic effect.
