The 3D printer is a technology that builds objects layer by layer using adhesive materials such as powdered metal or plastic, based on a digital model file. Because in the principle of 3D printer, the complex 3D manufacturing is transformed into a series of 2d manufacturing superposition, so almost any complex parts can be generated without mold and tools, which greatly improves the production efficiency and manufacturing flexibility. The principle of 3D printers seems simple enough, and while some products can be printed directly, there is still a long way to go before they can produce sophisticated products.
The main function of 3D printing z-axis movement, using screw nut drive to achieve linear movement. Compared with peers, the motor has the following advantages:
1, no clearance, high transmission accuracy: motor anti-backlash nut structure, rotor screw shaft and motor body without axial clearance; Nut can use two different materials to meet different customer requirements, brass clearance 0.1mm, can meet the general purpose 3D printing requirements, special resin material clearance can meet the high precision 3D printing requirements;
2. High life: the nut material of linear stepper motor is brass or polyformaldehyde, which is easy to wear during long time working and affects the transmission accuracy.
