A method for rapid prototyping by using linear light as sources employs DLP (Radiation Hardening Formation) or LCD, together with the portable devices and linear light source to treat the raw material in two stages. The first stage is to spread the raw material to a selected zone by nozzles or rollers and illuminating the material to let the material being processed and have physical o mechanical changes. The second stage is to use more powerful linear light source with the cooperation of the portable DMD (Digital Micromirror Device) or LCD (Liquid Crystal Display) to illuminate the material to make it have a second times of physical o mechanical changes. By the piling up the layers of the material, a complete 3-D work piece is obtained.

A method for rapid prototyping by using plane light as sources treats the raw material by two stages. The first stage includes a step of spreading raw material onto a defined zone by nozzles and rolling the material to have a flat surface and a step of illuminating the raw materials by plane light and electronic beams to cause a first time of physical or chemical changes. The second stage includes a step of using more powerful plane light source with cooperation with portable Digital Micromirror Device (DMD) or Liquid Crystal Display (LCD) to scan the selected zones of the material to cause a second time of physical or chemical changes, and a step of stacking the 2-D images so as to obtain a solid work piece.
