Comprehensive Study on Smart Materials Used In 4D Printing Technology Applications Review

Abstract

The current world encounters a huge application in additive manufacturing. One of the recent technologies branched from additive engineering is 4D printing technologies. The notion of 4D printing technology became a huge success because of its ability to change and reform. This ability helps to manipulate materials at micro and nano levels. This itself finds a lot of opportunities in the forefront industries like engineering, space technology, biomedical etc. Innovation of these novel materials and the modification of the manufacturing entities still pose a great challenge in the form of a blind wall. In this paper we have reviewed the smart materials like ceramics, hydrogels, smart metal alloys. This paper also incorporates the survey of smart materials and multi-materials along with its applications. We have also learned about the limitations of these materials which lead to the conclusion of the paper that includes information about the scope for exploration in this pitch.
