Which of the following statements is true for rapid prototyping?

Rapid prototyping is the fast fabrication of a physical part, model or assembly using 3D computer aided design (CAD). The creation of the part, model or assembly is usually completed using additive manufacturing, or more commonly known as 3D printing. A photopolymer or autopolymerising resin is deposited layer by layer and sets according to its chemical nature. Laser can also be used in the polymerization process. It is applicable in dentistry for printing prostheses, stents and models.
