Description
Technical field
The utility model relates to 3D printing technique field, is in particular a kind of colored 3D printhead.
Background technology
3D printing technique, i.e. rapid shaping technique, because its excellence is rapidly developed in the many advantages of existing subtraction processing technology.On present 3D printing market, colored 3D printer is actually rare, but the concept that prints of colored 3D and technology kind also very numerous and diverse.
In existing colored 3D printing technique, nozzle structure is often very complicated.
One, the shower nozzle of silk, alternate printing is entered respectively.This kind of technology is each self-configuring transfer structure of multiple printhead, though solve the shortcoming that material conversion brings, but complex structure, conversion printhead increases the time of printer model greatly, too increases the uncertainty changed between structure;
Two, there is the shower nozzle that porous enters a structure.Multiple color filamentary material is changed, but this kind of technology increases time when printing conversion, and when adding conversion silk material, more uncertain etc., prior art is the increase in shower nozzle cost more, or conversion time when adding printing and uncertainty.
On colored 3D Method of printing, mainly contain the following two kinds:
One, there is the extrusion molding of mixing polychrome silk material, adopt three primary colors filamentary material, mix in the showerhead, thus print polychrome 3D composite model.But not only nozzle structure is complicated for this kind of technology, and application filamentary material is dyed blended, reduces the validity of color.
Two, with each print layering shaping after, then to this layering have dyeing instruction region carry out ink jet dyeing.But this method adds dyeing time undoubtedly, and ink-jet density also has uncertainty.
The colored 3D printing head complex structure of prior art, the 3D model color-resolution printed is low, colour band reduction degree is low, and for solving defect in prior art, the purpose of this utility model is to provide a kind of colored 3D printhead.
For achieving the above object, the utility model discloses a kind of colored 3D printhead, comprise melt chamber and the nozzle affixed with melt chamber lower end, melt chamber upper end is provided with filament inlet, and filament inlet is connected with wire-feeding pipe one end, and the other end of wire-feeding pipe connects wire feeder; Filament inlet place is provided with dyeing apparatus.
Further, dyeing apparatus comprises ink gun, and ink gun is connected with filament inlet, and ink gun is connected with print cartridge by communicating pipe group.
The utility model arranges ink gun at filament inlet place, and dye to flowing through the filamentary material come from wire-feeding pipe, the filamentary material after dyeing enters melt chamber.The filamentary material entered in melt chamber is sufficiently colored, and the model therefore printed has higher color-resolution, and higher color rendition degree.
Further, ink gun is made up of ink nozzle and interim ink storage box.In interim ink storage box, mixing agitator is installed; Be provided with at least one subregion in print cartridge, each subregion holds a kind of color ink; Pusher is provided with in subregion.
Further, dyeing apparatus can be colored discs, is provided with the painted cylinder that at least one is connected with wire-feeding pipe, is provided with pusher in painted cylinder in colored discs; Also be provided with whirligig in colored discs, whirligig is provided with painted rod.
Further, whirligig is provided with the painted rod of at least one color.
Further, heater is provided with in melt chamber.
The beneficial effects of the utility model are: colored 3D printhead of the present utility model can realize dyeing before filamentary material enters melt chamber, make itself and ink fully dyed blended in melt chamber; And because be directly use ink to dye, thus reduce model more really, the model color-resolution printed is higher, colour band reduction degree is higher; In addition, the utility model structure is simple, is easy to operation, can realizes the continuous printing of color model.
