The sustainability of 3D printing for industrial usage is attributed to its characteristics, which include minimal material waste, ease of manufacture, low human participation, minimal post-processing, and energy efficiency. Various 3D printing techniques are covered in the study, along with their benefits and cons. All the materials that work with different kinds of 3D printing processes are explained in detail. Additionally, the document lists the several fields in which each kind of method finds application. Industry 4.0 has also been covered in detail in this section. According to the literature review, even though 3D printing has advanced significantly, there are still problems that need to be solved, like material incompatibility and material costs. Technologies used in Additive Manufacturing fall under the broad category of 3D printing. Each of them constructs objects in successive layers, with an average thickness of 0.1 mm. To put it simply, 3D printers fall into four categories. First, we have printers that extrude a material that is either molten or semi-liquid. Additionally, printers that firm photocurable resin exist. Thirdly, powder granules can be fused or bound together using printers. Last but not least, there are printers that fuse together sliced sheets of metal, plastic, or paper. It is now widely known that 3D printing has the potential to produce incredibly exciting and remarkable outcomes in the healthcare industry. The idea of using 3D printing in medicine is not new. In the late 1980s, work on the first commercial bioprinters and 3D printers got underway. But only because of increased funding and technological advancements over the past few years have the capabilities, applications, and demand increased.
