Problems solved by technology
[0003] At present, some large-scale 3D printers produce long-term wear and tear of the sealing ring when the filament enters, causing air to enter the nozzle, resulting in poor product quality.
In addition, due to poor sealing, the molten material in the nozzle will overflow the nozzle from the inlet of the silk material, resulting in waste

Description
technical field [0001] The invention relates to the technical field of 3D printers, in particular to a combined nozzle of a 3D printer. Background technique [0002] 3D printer, also known as three-dimensional printer, is a kind of cumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file, using special wax, powdered metal or plastic and other bondable materials. Print layers of adhesive material to create three-dimensional objects. At this stage 3D printers are used to manufacture products. The technology of constructing objects by printing layer by layer. The principle of a 3D printer is to put data and raw materials into the 3D printer, and the machine will build the product layer by layer according to the program. [0003] At present, some large-scale 3D printers produce long-term wear and tear of the sealing ring when the filament enters, causing air to enter the nozzle, resulting in poor product qual...
