The digitalization of the manufacturing industry has helped overcome several challenges associated with manual drafting of designs. The introduction of computer-aided design (CAD) software packages has added a whole new dimension to the manufacturing and 3D printing industry. CAD is defined as a software, with the help of which engineers, architects, and designers can digitally represent the design of the product to be constructed.
The advent of 3D printing technology has bridged the gap between the digital and the physical world. Similar in operation to 2D printers, 3D printers use thousands of layers of material which are printed layer upon layer with the help of an extruder to create the objects in 3D. Through this emerging technology, desktop 3D printers have made 3D printing accessible and affordable for a large number of population. Desktop 3D printers can be used in homes, offices, schools and universities, among other end-user sectors. The evolution in 3D printing technologies and gradual decrease in the cost of desktop 3D printers have led to the expansion of 3D printers in major domains of application. 3D printing has now spread over the world of clothing, shoes, frames, food, and experimenting with 3D printed dresses, chocolates and shoes.
