Abstract: A heat sink for a 3D printer includes a storage tank, a pipe loop, a pump, a heat dissipation unit, and a release film. The storage tank is configured to contain a printing material. The pipe loop is connected to the storage tank. The pump is connected to the pipe loop and configured to pump the printing material from the storage tank, so that the printing material circulates through the pipe loop. The heat dissipation unit is connected to the pipe loop. The printing material is pumped into the pipe loop, then subjected to heat dissipation by the heat dissipation unit, and re-injected into the storage tank successively. The release film is disposed at a bottom of the storage tank.

Abstract: A multiple light source correction apparatus and a method of use thereof are disclosed. The multiple light source correction apparatus (10) comprises a transparent thin plate (1) having a first correction pattern (12), a second correction pattern (13) and at least one third correction pattern (14). The first correction pattern (12) includes a first straight line (121) having first and second end points (1211, 1212). The second correction pattern (13) includes a second straight line (131) and two U-shaped frames (132). The second straight line (131) includes third and fourth end points (1311, 1312). The two U-shaped frame (132) is installed at externals of the third and fourth end points (1311, 1312) respectively. The third correction pattern (14) includes a third straight line (141) having fifth and sixth end points (1411, 1412). The first, second and third straight lines (121, 131, 141) are arranged parallel to each other.

Abstract: A stereolithography 3D (three-dimensional) printer and a method of adjusting temperature of printing materials thereof are provided. The stereolithography 3D printer has a material tank for accommodating print materials, a light module, a temperature-adjusting module, a temperature-sensing module, and a curing platform. The stereolithography 3D printer executes a procedure of controlling temperature for adjusting a temperature of the print material if a sensed temperature doesn't reach a default value, and executes a procedure of 3D printing for manufacturing a 3D physical model by using the print material whose temperature had been adjusted. The printing quality of the 3D physical models can be effectively improved via controlling the temperature of the print materials.

Abstract: A 3D printer and a liquid level sensing method are provided. The 3D printer includes a tank and at least one capacitive sensing module for sensing a liquid level of the liquid forming material in the tank. The at least one capacitive sensing module includes a first electrode pair disposed beside the tank, and the first electrode pair is used for producing an electric field, where the electric field passes through the liquid forming material.
