Abstract

The invention discloses a 3D printing feeding mechanism, which comprises a bracket fixing platform arranged horizontally. The nozzle, when in operation, connects the turbine to the wire-feeding motor. At the same time, select the number of wire-feeding branches according to the needs, pass the PLA wire between the turbine and its corresponding driven wheel, and press it on the turbine through the spring and the compression bracket. Between the wire feeding motor and the driven wheel, turn on the wire feeding motor, the wire feeding motor drives the worm to rotate, the worm drives the turbine to rotate, and the PLA wire is sent into the radiator through the friction between the turbine, PLA wire and the driven wheel, and the heat generated by the heater The heat melts the PLA filament, which is ejected through a nozzle. The realization of single motor conveying multiple wires reduces costs and saves installation space, simplifies on-site installation and debugging, and increases the conveying capacity of wires.

Description

technical field [0001] The invention relates to the technical field of 3D printing equipment manufacturing, in particular to a 3D printing feeding mechanism and its application method. Background technique [0002] 3D printer, a machine of rapid prototyping technology, is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. In the past, it was often used to make models in the fields of mold manufacturing and industrial design, and is now gradually being used in the direct manufacture of some products. [0003] The current mainstream 3D printing technologies mainly include four types: stereolithography (SLA), three-dimensional powder bonding (3DP), selective laser sintering (SLS), and fused deposition rapid prototyping (FDM); among them, based on stereolithography technology, Although 3D printers with three-dimensional powder bonding technology and selective laser sintering t...
