Description

Technical Field [0001] The present invention relates to a three-dimensional printer supply nozzle having a spiral supply path,

The present invention relates to a nozzle provided in a three-dimensional printer for fabricating a prototype having a three-dimensional shape, wherein the size of the outer diameter of the nozzle is gradually reduced to the lower end (130) A nozzle body portion having a central axis and a shaft coupling portion 120 formed for a predetermined coupling therebetween and a central axis of the upper end portion 110 of the main body portion, A nozzle coupling portion 20 formed to communicate with the inner circumferential surface and having guide slits 210 radially formed therein to guide the coupling; The present invention relates to a three-dimensional printer supply nozzle in which a spiral supply path 140 is formed.

Generally, in order to produce a prototype having a three-dimensional shape, there is a mock-up production method manually performed by a design drawing, and a CNC milling production method using a computer control.

Such a mock-up manufacturing method is manual, so it is difficult to precisely control the numerical value. It is not precisely matched with the design drawings, and it takes a considerable amount of time. The CNC milling production method allows precise numerical control, There are many disadvantages in that it is difficult to process these parts.

Due to these disadvantages, a three-dimensional printer method has recently emerged in which product designers and designers can directly produce three-dimensional prototypes using three-dimensional modeling created by a computer.

The product molding method of the 3D printer is divided into a so-called additive type in which a target object is formed in a two-dimensional plane form, a so-called additive type in which the object is melted and laminated while being laminated in three dimensions, . As a kind of the additive type, a wire or filament made of thermoplastic plastic is supplied through a supply reel and a transfer roll, and the supplied filament is melted in a heater nozzle mounted on a three-dimensional transfer mechanism relatively positioned with respect to a work table in XYZ three directions There is a filament melt lamination molding method in which a two-dimensional planar shape is formed by discharging it and a three-dimensional object is formed by laminating it on a work table.

Conventionally, a 3D printer which melts and laminated such filaments has conventionally been capable of molding into a single color, but it has been difficult to form products of various colors. In order to replace the color, it is necessary to replace the filament supply reel with a filament supply reel of a different color and then connect it to the heater nozzle again. Therefore, it takes much time to replace the filament, Since the melted portion is hardened, a discontinuous joint is formed at the succeeding portion, so that the appearance and integrity of the product is deteriorated,

There is a problem that the coarse strength is lowered.

However, since a plurality of heater nozzles are provided, the structure of the apparatus is complicated, the operation takes a long time, and the control of the apparatus is considerably difficult. Respectively. In addition, filaments having different colors can not be mixed well, resulting in a disadvantage that colors can not be realized in a desired color by a user.
