Description

The recycle system of the colored 3D printer of hypervelocity

Technical field

The utility model relates to the nozzle component recycle system on a kind of printer, is specifically related to the recycle system of a kind of colored 3D printer that exceeds the speed limit, belongs to colored 3D printer field.

Background technology

Printing in kind is now popular technology, refer to printing curve on material object, such as printing curve on phone housing, printed material is made not only to be confined to the planar mediums such as paper, such as CN202213316U discloses a kind of universal colorful entity digital printer, it is possible to printing word or pattern etc. on the material object of soft, mechanically resistant material. But the figure that existing printer is got is all simple colored figure, lacks stereoscopic sensation, vivid not, although and by the figure of the mode carve of embossment, there is stereoscopic sensation, but the cost of engraving is too high, efficiency is lower, it is difficult to produce in enormous quantities.

3D prints production technology and belongs to shaping increasing material manufacturing technology, by software, the 3D solid figure of Computer Design is resolved into the section of some layer planes, by 3D printer printout, thus produces parts needed for unlike material and component; Because of the advantage such as component of its flexibility, customized, near-net-shape complex structure, there is wide development prospect. The production method developed at present comprises laser stereoforming method, selective laser sintering process, selective electronic bundle sintering process, heat are melted and piled up the method for forming etc., and namely such as CN103895228A discloses a kind of heat and melt and pile up the colored 3D of the method for forming and print equipment.

It is generally that powder 3D prints (3DP) that traditional 3D prints, and is a kind of 3D Method of printing utilizing droplet ejection, powder bonded technology. Under the control of the computer, according to the information of current point layer cross section, on the one layer of powdered material completed in advance, jet binder selectively, makes part powder bonded to shower nozzle, forms a layer cross section thin layer; One layer be shaped after, worktable declines a thickness, carries out the paving powder of next layer, constituency jet binder then, and shaping thin layer also can stick to one with formation of parts simultaneously; Constantly this process of circulation, till part processes; Usually part formed thereby also needs certain aftertreatment, such as drying, sintering etc., thus obtains last part. But, existing powder 3D printer needs the long period to carry out for powder and binding agent, set time is long, and it is huge to take space, operating process is lengthy and jumbled, and it is convenient not particularly to clear up when not being shaped powder, it is easy to cause powder to pollute surrounding environment, for this reason, CN103935037A discloses the colored 3D printer of a kind of integrated form powder.

How material object printing being combined with 3D printing technique, both obtained the stereoeffect of 3D printing, can effectively reduce costs again, it is to increase production efficiency, thus reach fast, efficiently, flexibly, applicable production in enormous quantities is the target that printing industry is pursued always. Just for above-mentioned reasons, the rapid printer that can play printed color 3D effect photo will have huge use value and market outlook, as the patent No. be 2015104586204 Chinese patent and the patent No. be that 2015104596206 Chinese patents give a kind of rapid printer that can print colored 3D effect photo, but this device needs three-shaft linkage when printing, shower nozzle needs back and forth repeatedly operation, although shower nozzle can high-speed mobile, but the space that printing effect is still also improved.

(when generally having multiple nozzle component, this step performs once)

Optionally repeat above step 3 and 4, until printing complete.

In above step 1, image procossing resume module mainly comprises following step by step 1 '-3 ':

Step 1 ': input image to be printed to the receiver module in image procossing module;

Step 2 ': in hierarchical block, input the layering number of plies,

Step 3 ': module to be calculated has calculated and has started the recycle system after the data obtained are passed to the recycle system by output module.

In above step 2, thing to be printed or workpiece 6 are placed on worktable 4, on the distance principle of thing to be printed and shower nozzle more near more good, but prerequisite to scrape shower nozzle, for this reason, arrange infrared rays to survey the height that high sensor treats printed matter and measure, the distance of general control thing to be printed and shower nozzle is between 0 to 20mm, preferably 1 to 15mm, it is more preferable to 2 to 10mm, it is also preferred that 3 to 5mm.

Above step 3 prints matrix material on workpiece or thing to be printed, it is possible to prints one or many, depending on thickness and the printing effect of required matrix material;

Above step 4 prints colorful material on workpiece or thing to be printed, it is possible to is last printing, has namely printed colorful material and namely has terminated to print; But when needing print pattern solid or 3D effect thickness that is relatively obvious or matrix material thicker, this colorful material can also print repeatedly, such that it is able to avoid patterned side to show out substrate material.

Above step 3 and 4 needs to work in coordination with operation by the recycle system and worktable 4 and completes.

According to the utility model, needing to check that whether the material holding the recycle system is sufficient before starting the recycle system, whether equipment state is normal, and also fixed on the table by trade union college to be printed before activation;

According to the utility model, before the recycle system performs print job, it is necessary to moved to by nozzle component above liquid sucking device 5, and the jet pipe on nozzle component is done imbibition process;

According to the utility model, in print procedure, need to be moved to by nozzle component above waste collection groove 1 after the reciprocal several times in X-axis direction every the scheduled time or nozzle component, and perform loose to spray operation, in the utility model preferably, nozzle component moves back and forth 3-15 time along X-axis direction, it is preferable that 5-12 time, it is more preferable to perform once loose spray operation after 7-10 time.

Further, in the process of recycle system print image, first it is the nozzles spray material being loaded with on the jet pipe of white/transparent color matrix material, this jet pipe prints out the image of white or transparent color by spraying material, and this image has stereoscopic sensation, part region on image is outwardly, finally has the nozzles spray material on the jet pipe being loaded with redness, yellow, blueness and black, completes to treat the print job printing workpiece.

Preferably, the region to be printed of workpiece to be printed is white, to strengthen vision effect, if this region to be printed is non-white, it may be considered that first this region is sprayed into white, in addition, white described in the utility model/transparent color material, it is preferable to white mass.

The printer provided according to the utility model and the product that prints out of Method of printing be colored, with the image of stereoscopic visual effect, this image is basically identical with the image being delivered in image procossing module, difference is that this image is not plane figure, it has certain height in the region darker in color, namely this region is protruding upward, enhance the stereoscopic sensation of image, seem more lively, vivid.

More than combine and preferred embodiment the utility model is illustrated, but these enforcement modes are only exemplary, only play the effect of explanation property.
