A three-dimensional printer includes a light source module, a liquid crystal display, a working tank and a working platform. The light source module includes a plurality of light emitting elements. The liquid crystal display is a monochromatic liquid crystal display without sub-pixels. A light beam emitted from the light emitting elements is toward the liquid crystal display. The liquid crystal display is disposed adjacent to a closed side of the working tank and arranged parallel to the working tank. The working tank is provided for accommodating a photosensitive material, which is in a liquid state. The working platform is disposed adjacent to an open side of the working tank. At least a portion of the light beam passes through a penetration region of the liquid crystal display based on a printed pattern and causes polymeric crosslinking of the photosensitive material in a curing region thereof. The working platform time-correspondingly and intermittently contacts the curing region, so that a three-dimensio
