3D printing technology is a boon for humans. It is the process by which you can form any solid shape from a digital model. It is based on additive manufacturing technology where a three dimensional object is created by adding layers. It is also known as rapid prototyping. Doesn’t it sound interesting? In this technique you can remove the unwanted material by cutting or drilling. There are many printers which use digital technology to do 3D printing processes. The sales of these machines have grown with the time. Chuck Hull of the 3D system Corp, Inc made the first 3D printer. What are the applications of 3D printing technology? Initially, manufacturing companies used this technology. With the introduction of 3D printing technology, you can go for mass production.
