Abstract
Description
The present invention relates to a 3D printer extruder including an integral nozzle, and more specifically, a nozzle for injecting molten filaments and a connection pipe for separating the main block of the extruder from the hot plate are integrally formed, And to a 3D printer extruder including an integral type nozzle that makes it convenient.
Conventional 3D printers have been developed for the purpose of prototyping products before they are commercialized in the enterprise. However, they have been developed in the early stage, which was confined to plastic materials, expanded to nylon and metal materials, and commercialized in various fields as well as industrial prototypes Respectively.
In general, it is divided into a 3D printer method (additive type or rapid prototyping method) and a cutting type machining method (computer numerically controlled engraving method) in which a large lump is cut by stacking up a layer by a method of forming a three-dimensional form. The object can be determined in various ways.
The FDM (Fused Deposition Modeling) method is typical in the laminated type, and is called a FFF (Fused Filament Fragment). A plastic wire called a filament is used as a material.
The material is similar to the glue gun used in home applications in the form of melting the melt while passing through a heated extruder and laminating the material flowing through the nozzle onto the output plate to shape the required shape.
The key to material extrusion processing technology is the extruder, which melts and extrudes the material. It basically includes a motor to move the material and apply pressure to the nozzle (Hot End).
The extruder is divided into a direct extrusion type and a bowden type according to the position of the extrusion motor. In the direct extrusion type, since the extrusion motor is located directly above the nozzle, the nozzle and the filament Since the distance is short, stable raw material supply is possible, and the output quality is good. However, there is a disadvantage that the extrusion motor is like a nozzle and is heavy and disadvantageous to high speed output. In Bowden type, the compression device is located outside the printer. In order to compensate unstable supply, Teflon tube connects the head part and the crimping part. The driving part of the nozzle is light and easy to use for high speed output. The motor is subjected to a load as much as possible, and the speed of extrusion response is slowed, and the output quality may deteriorate.
The conventional direct extrusion method includes a
As described above, the
SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the prior art described above, and it is an object of the present invention to provide an apparatus and a method for manufacturing a filament, which comprises a guide pipe integrally formed above a nozzle for injecting molten filaments, And an integral nozzle for pressing the guide pipe penetrating through the hot plate to prevent the nozzle from being detached from the hot plate by fastening the pressing means to the through hole formed at one side of the hot plate, The object of the present invention is to provide a 3D printer extruder.
As means for solving the above-mentioned problems, in an embodiment of the present invention, an extruder main block; A step motor disposed on a rear surface of the extruder main block and capable of driving a conveyance part inserted in the extrusion crab main block; A feeder positioned inside the extruder main block and capable of discharging the filament F introduced from the upper side to the nozzle; A hot plate positioned at a lower portion of the extruder main block and capable of vibrating the inflowing filament; And a nozzle for vertically penetrating the hot plate and for injecting a filament that has passed through the transfer part, wherein the nozzle comprises: a guide tube for guiding the filament F introduced into the extruder main block downward; And a discharge unit located at a lower portion of the guide tube for discharging the fused filaments.
In a preferred embodiment of the present invention, the transfer unit comprises: an extrusion gear driven by a stepping motor; And a guide bearing rotatably engaged with the extrusion gear and guiding the filament F inserted inward. The guide bearing is movable left and right by the filament changing switch, so that the filament can be taken out.

As a preferred embodiment of the present invention, the front surface of the extruder main block further includes a cooling fan to prevent the inflow of filaments F from being melted.
As a preferred embodiment of the present invention, a side surface of the hot plate may further include a pressing means to press the guide pipe passed through the hot plate by using the pressing means.
According to a preferred embodiment of the present invention, a stopping jaw is formed between the guide tube and the discharge unit included in the nozzle, so that the hot plate can be prevented from entering the lower portion of the discharge unit by the latching jaw .
According to the present invention, the following effects can be achieved by this configuration.
In the 3D printer extruder including the integral nozzle according to the present invention, the nozzle includes a discharge portion for discharging the filament and a circular guide pipe projecting outwardly from the discharge portion, wherein the discharge portion and the guide pipe So that the effect of facilitating the connection and disassembly with the hot plate can be achieved.
