It is based on a digital model file and uses special wax materials, powdered metal or plastic and other adhesive materials to print layers of adhesive materials to make three-dimensional objects. At present, 3D printers are used to manufacture products. The technology of constructing objects by printing layer by layer. The principle of 3D printer is to put data and raw materials into the 3D printer, and the machine will make the product layer by layer according to the program. The commonly used FDM type printer prints layer by layer by heating and melting the plastic filament, which has a wide range of applications.

[0003] However, traditional FDM type 3D printers still have certain problems during use: first, when operating this type of printer, the plastic filament needs to be pushed into the hot melt module to heat it into liquid, and then transported to the nozzle. During the printing process, some plastic is easily adhered to the surface of the nozzle, and then sticks to it after cooling, which is difficult to clean and collect, resulting in affecting the subsequent printing of other products. Secondly, many products take a long time to print. Operators generally set the product parameters, start printing, and then do other things. In order to facilitate the monitoring and control of the printed products, some printers will install cameras inside, but the cameras cannot control the position and adjust the angle, resulting in users not being able to know in time when problems occur in certain parts of the product.
