Technical Field
[0001] The utility model relates to the technical field of 3D printing, and more specifically, to a light-curing 3D printer with a material recycling function. Background Art
[0002] A 3D printer is a rapid prototyping machine that uses digital model files as a basis and uses powdered metal or plastic and other bondable materials to print products layer by layer. Stereolithography is the earliest practical rapid prototyping technology for 3D printers. The lifting platform moves vertically to the height of a layer and then solidifies another layer. In this way, layers are stacked to form a three-dimensional entity. After the product is printed, the remaining materials cannot be recycled, resulting in a waste of resources. Therefore, a photocuring 3D printer with a material recycling function is needed.
[0003] During operation, the existing device moves the printed three-dimensional object to other working instruments to perform the above operations, which causes a waste of raw materials and requires the three-dimensional object to be moved.
[0004] After searching, a Chinese patent with publication number CN213733397U discloses a light-curing 3D printer with a material recycling function, including a base and a recycling box. The structure is fixedly connected to the second straight tube through a curved pipe, the first straight tube is connected to the material chamber, and the curved pipe connects the first straight tube and the second straight tube, so that the material can be recycled into the recycling box for centralized processing, which increases the utilization rate of the material and can effectively save production costs.
[0005] However, the above device may encounter the following problems during use: the structure collects the recycled materials through a box. After the box is full of collected materials, when the box is slid out of the recycling box, liquid in the first straight tube will not be discharged, causing it to drip into the recycling box and causing waste. In addition, it is time-consuming to replace the box, thereby reducing the use efficiency of the device. Utility Model Content
