摘要：The present paper is providing overview information in rapid prototype manufacturing process of 3D printing for multifunctional applications. To make precise and useful products, 3D printers are attractive method over 2D printers because of multiple types of material within a single build-up cycle. This technology allows the printing of multiple colors. The multi-functional material printers work for a single family of a materials like polymers, for instance and are largely used for prototyping applications. Various factors mostly generated to materials themselves, which make further improvement in prototype printing. Mostly processes are built-up around an ideal material that responds to a narrow range of temperature inputs or light frequency. Using heat or light, printers often liquefy or solidify substances to manipulate the material into specific forms.
