Detailed description of the invention
The present invention is described further with specific embodiment below in conjunction with the accompanying drawings:
As it is shown in figure 1, the structural representation of 3D printing device of the present invention, print the nozzle 1 of material including extrusion, also comprise
Have many can be with the feed pipe 2 of transfer printing material, feed pipe 2 is the pipeline of transfer printing material, wherein print material permissible
It it is the filament etc. made of ABS filament, PLA filament, wax silk or food.Every feed pipe 2 is all each provided with driving
Print the feed component 3 that material moves in feed pipe 2.By the driving of feed component 3, it is fed into charging from outside
Thread printing material in pipe 2, can transmit the most constantly.In the lower section of every feed pipe 2, respectively
From being provided with heater 4, heater 4 adds heat fusing, heater 4 to the thread printing material in feed pipe 2
Lower section is provided with melt mouth, and melt mouth is provided with valve, the batch mixing chamber 5 printing material that each melt mouth is melted with held beneath
It is connected, between heater 4 and batch mixing chamber 5, is provided with metering valve 10, for the printing material metering that melt mouth is flowed out,
So that printing material required color can accurately be configured.Melted printing material enters batch mixing through melt mouth, metering valve 10 successively
Chamber 5.Printing material in every feed pipe 2 the most all enters in batch mixing chamber 5 and mixes.Batch mixing chamber 5 includes a pipe
Shape exports, and this pipe-type outlet is the nozzle 1 of 3D printing device.
Different feeds pipe 2 can be sent into the thread printing material of different colours.The thread printing material of different colours, through adding
All enter in batch mixing chamber 5 after heat fusing.The printing material of the different colours after Rong Rong in batch mixing chamber because of the continuous feeding in outside
The extruding printing material, and produce color mixture and produce into new color.Thus, the 3D printing device that the present invention provides,
Colour print can be carried out.By the thread printing material of supply different colours combination, the article of multiple color can be printed.
Such as, for the 3D printing device containing two feed pipes, print material be identical material, same size with
And in the case of the identical amount of feeding, in two feed pipes, feeding is red respectively and the ABS filament of yellow, through melted, mixing
After can extrude orange filament, such that it is able to utilize red and yellow the material that prints to print orange article.And to two
Difference feeding yellow and blue ABS filament in root feed pipe, can extrude green filament after melting, mixing, thus
Yellow and the blue material that prints can be utilized to print the article of green.
For another example, for the 3D printing device containing three feed pipes, it is identical material, identical thickness printing material
And in the case of the identical amount of feeding, in three feed pipes, feeding is red respectively, yellow and the ABS filament of blueness, through molten
Melt, mix after can extrude the filament of black, such that it is able to utilize the printing material of red, yellow and blueness to print black
Article.
What deserves to be explained is, difference feeding yellow and blue ABS filament in two feed pipes, and right by metering valve 10
The amount of feeding of feeding yellow ABS filament measures, and/or by the metering valve 10 amount of feeding to feeding blueness ABS filament
Measure, close the valve of melt mouth when reaching aequum, if making the yellow print material will be than blue printed matter material
Many, through the mixing in batch mixing chamber 5, jade-green filament can be extruded from nozzle 1, print jade-green article；If
The feed speed making yellow ABS filament is slower than the feed speed of blue ABS filament, after in batch mixing chamber 5,
Yellow print material will be fewer than blue printed matter material.Through the mixing in batch mixing chamber 5, navy blue can be extruded from nozzle 1
Filament, print navy blue article.
For strengthening the melted mixed effect printing material of different colours so that mixed color is more uniform, the application
The 3D printing device of embodiment, also includes being arranged at agitator 6 on batch mixing chamber 5, and this agitator 6 is in batch mixing chamber 5
Melted printing material is stirred, to strengthen producing after the melted printing material of different colours mixes the uniformity of new color
And stability.
As it is shown in figure 1, in embodiments herein, agitator 6 includes puddler and the stirring sheet being arranged on puddler,
Puddler stretches into batch mixing chamber 5, and the stirring sheet on puddler is positioned in batch mixing chamber.Stirring sheet is driven to stir by puddler,
The mixability of material melted in batch mixing chamber can be strengthened.
As it is shown in figure 1, be provided with switch element 7 on all or part of feed pipe 2, switch element 7 is arranged at feed component
On feed pipe 2 between 3 and heater 4.Switch element 7 can be turned on or off feed pipe 2 transmission at its place and beat
The path of print material.Thus it is provided with the feed pipe 2 of switch element 7, it is also possible to not transfer printing material, and do not affect remaining
Feed pipe 2 transfer printing material.When the 3D printing device using the embodiment of the present application carries out 3D printing, it is not provided with
The feed pipe 2 of switch element 7, needs to supply thread printing material；And it is provided with the feed pipe 2 of switch element 7, the most permissible
