Abstract
Due to their unique ability of changing shape based on external stimulus, smart materials are finding applications in diverse fields like electronics, medical, construction etc. Smart materials include thermochromic pigments, shape memory polymers, shape memory alloys, self-healing materials and hydrogels. Self-healing materials are man-made substances that have an integral ability to spontaneously heal damages themselves without any diagnosis and human. Additive manufacturing or 3D printing has become popular all around the globe due to benefits like reduced wastage, ease of customization, rapid prototyping and direct production. Combined use of 3D printing and concept of smart materials have led to the development of 4D printing. This paper presents an overview of the smart materials and its detailed classification. An attempt is also made to present the application of additive manufacturing on smart materials and the latest research trends in the domain.
