(2) Feeding working cylinder: providing molding and support for powder materials.
(3) Residue recycling bag: it is installed in the mold shell to recycle the excess powder in the powder laying process.
(4) Powder spreading roller device: including powder spreading roller and driving system. Their function is to spread the powder material evenly on the working cylinder and compact the powder at the same time.
(5) Nozzle: The adhesive used for spray molding in the working cylinder is an important part of 3D printing rapid prototyping, which bonds the powder between different layers together.
(6)X-Y-Z three-dimensional transmission system: drive the X and Y nozzle cars to move two-dimensionally, and drive the forming working cylinder and the feeding cylinder to move up and down along the Z axis.
(7) Machine body and shell: the shell provides mechanical support and necessary working environment for the rapid prototyping system.
Generally speaking, before buying a 3D printer, you need to know enough about these 3D printer accessories. After you are familiar with the basic functions and functions of these components, you can better use 3D printing equipment. There are also nozzles, hot beds and so on. All parts are easy to wear. If you don't understand these parts, it will not be conducive to your analysis of the working conditions of 3D printers. If anything goes wrong with the 3D printer, you don't know how to fix it. Therefore, it is very important to know and be familiar with these spare parts.
