The pros of using 3D printing would include making processes finish faster. In a design company for example, the usual process would be first come up with the design of the new product. Once the design has been approved, they send the design to a third party company to make the prototypes. The prototypes would be sent to the company for final checking and modifications. Overall, this would take weeks. With the help of 3D printing, this process would be shortened because once the company has the design they can just make the prototype on their own.
