Possibilities of Using 4D Printing and Smart Materials

Abstract

3D printing as an additive manufacturing technology is becoming more and more widespread today, both for industrial applications and for hobby use at home. During 3D printing a computer model be realized layer by layer using some kind of printing technology. As the field of application has expanded, a new concept has also emerged, called 4D printing, where the fourth dimension
has become time. The printed material thus created will be able to change, transform or move according to external influences (e.g. temperature, pressure, humidity). The range of materials used for printing has now become very wide, and the so-called smart materials have also appeared,
opening up new horizons in the field of additive manufacturing.
