A review on 3D printing: An additive manufacturing technology

Additive manufacturing, often known as 3D printing, is a type of digital fabrication technique that builds physical items from a geometrical model through the addition of materials. The field of 3D printing is one that is rapidly expanding. 3D printing has been a common practice around the world in recent years. Mass customization and manufacture of open-source designs are becoming increasingly common uses of 3D printing in the agricultural, healthcare, automotive, and locomotive industries. Using a CAD model as a starting point, 3D printing technology can build a three-dimensional object layer by layer. This paper provides an overview of the different types of 3D printing techniques, Classification, Materials used, & their applications in various sectors. Copyright (c) 2022 Elsevier Ltd.
