A light-curing 3D printer includes a main-tank, a printing platform, a lighting unit, a liquid material contained in the main-tank, an isolation fluid contained in the main-tank and floating upon the liquid material, a membrane arranged upon the isolation fluid, and an auxiliary mechanism. The 3D printer controls the lighting unit to emit light toward the liquid material according to slicing data of one cured-layer of a 3D model for forming a 3D object. The 3D printer then controls the printing platform to lower and activates the auxiliary mechanism to keep varying the status of the isolation fluid. Next, the 3D printer determines whether the 3D model is completed, and controls the lighting unit to emit light according to slicing data of a next cured-layer if the 3D model is not yet completed.

Light-curing 3D printer capable of quick printing and liquid-level smoothing

A 3D printing system includes a tank filled with a liquid forming material; a platform movably disposed above the tank; a lighting module including a plurality of LEDs disposed below the tank and used for providing light projecting toward the liquid forming material, and a controlling module coupled to the lighting module and configured to drive the lighting module to generate light that is focused onto a focus plane between the platform and the tank and having a certain distance with the bottom of the tank for solidifying the liquid forming material on the focus plane to form a cross-sectional layer, wherein the controlling module uses the brightness of one of the LEDs as a basis for varying that of the other LEDs, so that the liquid forming material solidified in single (scanning) procedure can have approximately the same hardness.

Three-dimensional printing system

The three-dimensional printing apparatus includes a tank, a platform, a lighting module, a control unit, a photosensitizer coating unit, and an exposure and development unit. The tank is filled with a liquid forming material, and the platform is movably disposed above the tank. The lighting module is used for providing light projecting toward the liquid forming material. The control unit coupled to the platform and the lighting module is configured to control the platform to move along a first direction, such that at least one layer object of a three-dimensional object is cured on the platform by layer. The photosensitizer coating unit is coupled to the control unit and configured to form at least one photosensitizer film on the layer object. The exposure and development unit is coupled to the control unit and configured to expose the photosensitizer film by exposing and developing to color the three-dimensional object.

Stereo lithography three-dimensional printing apparatus and method of forming colored three-dimensional object

An automotive intraoral scanner applied in a mouth includes a biting piece, a track piece and at least one mobile image processing set. The biting piece is sandwiched between two rows of teeth. The track piece is installed in the biting piece and disposed corresponding to the rows of teeth, and a shape of the track piece is similar to a shape of the rows of teeth. The mobile image processing set is installed on the track piece and moved along the track piece, and the mobile image processing set is disposed corresponding to the rows of teeth. Therefore, the automotive intraoral scanner has advantages of easy operation.
