Abstract

The invention discloses a feeding mechanism for 3d printing. The feeding mechanism comprises a support fixing platform which is horizontally arranged and in a disc shape, and a turbine mounting platform, a radiator, heaters and a nozzle are sequentially arranged below the support fixing platform from top to bottom in the vertical direction. In operation, turbines and a wire feeding motor are connected, meanwhile, the number of wire feeding branches is selected according to needs, poly lactic acid (PLA) wires penetrate through the turbines and driven wheels corresponding to the turbines, and the PLA wires are pressed between the turbines and the driven wheels through springs and pressing supports; the wire feeding motor is started and drives worms to rotate, the worms drive the turbines to rotate, and the PLA wires are fed into the radiator through friction force between the turbines, the PLA wires and the driven wheels; heat generated by the heaters is used for melting the PLA wires, and the molten PLA wires are sprayed from the nozzle. Multiple wires can be conveyed through the single motor, so that the cost is lowered, and the mounting space is saved; onsite mounting and debugging are simplified, and the wire conveying amount is increased.

Description

technical field [0001] The invention relates to the technical field of 3D equipment manufacturing 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 la...
