3D printing is a way manufacturing in the digital era. 3D printing is any of various processes in which material is joined or solidified under computer control to create a three-dimensional object, with material being added together. 3D printing is used in both rapid prototyping and additive manufacturing.
Industry 4.0 is the next generation manufacturing & Digitally connected with automation,IOT,3D printing,Robotics & Cloud Computing. 3D printing is a stepping stone in that process. 3D Printers simplifies the process of prototyping. An Idea is converted to a working prototype with 3D Printers.
