Problems solved by technology

[0004] In order to solve the problem that the thermoplastic material of the existing 3D printer is heated and melted in the nozzle, the present invention proposes an extrusion nozzle structure of the FDM 3D printer, which can greatly reduce the temperature at which the nozzle is transferred to the wire guide tube, and reduce the temperature of the thermoplastic material. The probability of being melted greatly reduces the failure of the guide wire tube

Abstract

The invention provides an extrusion spray-head structure of an FDM (Fused Deposition Modeling) 3D printer. The extrusion spray-head structure comprises a heating block, a wire conduit and a nozzle, wherein the nozzle is arranged at the bottom end of the wire conduit; the heating block is arranged at the part in which the nozzle is connected with the wire conduit; a teflon tube is arranged in the wire conduit, and a stainless steel tube is arranged at the bottom end of the teflon tube and corresponding to the heating block in position; a radiator is arranged on the outer surface of the wire conduit. With the adoption of the spray-head structure, the temperature transferred from the nozzle to the wire conduit can be greatly decreased, so that the probability of melting thermoplastic materials can be reduced, and as a result, the fault in the wire conduit can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional printers, and in particular relates to an extrusion nozzle structure of an FDM three-dimensional printer. Background technique [0002] A three-dimensional printer, also called a three-dimensional printer (3DPrinter, 3DP for short), is a process of rapid prototyping, which uses layer-by-layer accumulation to produce a three-dimensional model layer by layer, and its operation process is similar to that of a traditional printer. FDM (Fused Deposition Modeling) process Fused deposition manufacturing process 3D printer is a kind of common 3D printer. The materials used are generally thermoplastic materials, such as wax, ABS, nylon, etc., and are fed in filament form. The material is heated and melted in the nozzle, and the nozzle moves along the section profile of the part and the filling track, and at the same time extrudes the molten material, and the material solidifies rapidly and coagul...
