Technical Field

[0002] 3D printer, a machine of rapid prototyping technology, is a technology that uses digital model files as the basis, uses powdered metal or plastic and other bondable materials to construct objects by printing layer by layer. In the past, it was often used to make models in the fields of mold manufacturing, industrial design, etc., and is now gradually being used for the direct manufacturing of some products.

[0003] During the printing process of existing 3D printers, a small amount of material extruded by the nozzle will overflow onto the carrier plate, especially at the edge of the model or at the complex structure. If there is residual material or dirt on the carrier plate, it may affect the fit between the model and the carrier plate during the next print, causing the model to shift or warp during the printing process, affecting the printing quality. Some 3D printers with a cleaning structure usually use a continuous wiping method to clean the surface of the carrier plate. Continuous wiping can easily cause the impurities after cleaning to adhere to the surface of the carrier plate again, thereby causing the accumulation of impurities on the surface of the carrier plate, affecting subsequent use. To address this problem, we have proposed a 3D printer with a cleaning function. Utility Model Content

[0028] In the present invention, when printing is required, a digital three-dimensional model is created through computer-aided design software. After creation, the three-dimensional model is imported into the control software of the printing device 4. The software slices the model and divides it into many thin layers. Next, the printing device 4 controls the nozzle or other molding components according to the slice information to stack the material layer by layer according to the predetermined path. The material can be plastic, metal, ceramic, resin and other types. After each layer of material is stacked, it will be cured or bonded to form a solid plane. Then continue to stack the next layer, and repeat this process until the entire object is printed. During the printing process, a small amount of material extruded by the nozzle will overflow onto the carrier plate 2. After printing, take out the printed model. After taking it out, if you need to clean the dirt remaining on the surface of the carrier plate 2, press the flat rod 72 into the fixed frame 71.
