Description
Technical field：
The present invention relates to 3D printer technical field, in particular to a kind of 3D printer and its printing flow manipulation
Method.
Background technology：
Using printer just as one envelope of printing is believed：Dub " printing " button on computer screen, a digital document just by
It is sent on an ink-jet printer, one layer of ink is sprayed onto the surface of paper to form a secondary two dimensional image by it.And in 3D printing
When, software completes a series of digital slices by CAD technology (CAD), and the information transmission that these are cut into slices is to 3D
On printer, can be stacked up for continuous slim aspect by the latter, until a solid body shaping.3D printer is beaten with tradition
The maximum difference of print machine is that " ink " that it is used is raw material true.
The form for stacking thin layer has varied.Some 3D printers use the mode of " ink-jet ".For example, one entitled
The 3D printer company of Israel of Objet is using printer head by one layer of very thin liquid plastic substance spray in mold pallet
On, this coating is then placed in being processed under ultraviolet.Mold pallet declines minimum distance afterwards, for next layer of stacking
Come up.The company Stratasys that an other general headquarters are located at Minneapolis city of the U.S. is called " fused deposition modeling " using one kind
Technology, whole flow process is that plastics are melted in shower nozzle, then by way of depositing plastic material fiber just formed thin layer.
Also some systems use powder particle as print media.Powder particle is sprayed forms one on mold pallet
The very thin powder bed of layer, then the fluid binder by spraying solidified.It can also be called " laser sintered " using one kind
Technology founding into designated shape.This technology that also exactly German EOS Corp. uses in its superposition process manufacturing machine.And Switzerland
Arcam companies be then using the electron stream fusing powder particle in vacuum.Above-mentioned these are only many shaping sides
A part in formula.When running into comprising labyrinth as hole and cantilever, be accomplished by medium add gel or its
He is supported or for taking up space material with providing.This amount of powder will not be last only to be fallen with water or gas washout by founding
Supporter just can form hole.Nowadays can be used for printing medium wide variety, from various plastics to metal, ceramics and rubber
Gelatin substance.Some printers can also combine different medium, and one, the object that order is printed is hard and other end is soft.
SLA (Stereo Lithography Apparatus) technology is exactly laser three-dimensional engraving technology, is mechanical, sharp
Light, photochemistry, software, the crystallization of control technology.Based on the principle that photosensitive resin is solidified by ultraviolet light, computer controls swash
Light successively scans the photosensitive resin of solidification liquid, and the section of each layer of solidification is obtained by the three-dimensional CAD model software hierarchy of part
Arrive, until finally obtaining photosensitive resin material object prototype.Photocureable rapid shaping should be precision highest, surface in 3D printing technique
Also most smooth, the current minimum material thickness of the technology can reach 25 microns (0.025 millimeters).But photocureable rapid shaping
Technology also has two deficiencies, and photosensitive resin raw material first has certain toxicity, protection is should be noted when operating personnel use, secondly light
The prototype of curing molding is very good in terms of outward appearance, but intensity aspect still can not be general main compared with real manufactured goods
For prototype checking aspect, rapid prototyping is then converted into technical grade product by a series of subsequent treatment operations.This
Outward, the equipment cost of SLA, maintenance cost and material cost are all higher, therefore, the 3D printer based on photocuring technology
It is mainly used in professional domain, domestic desktop domain variability is not applied.
Therefore, it is badly in need of providing a kind of the SLA 3D printers and its Method of printing of rapid shaping, to solve prior art
It is not enough.
The application for a patent for invention of Application No. CN201410461645.5 discloses a kind of SLA 3D printings of rapid shaping
Machine, including SLA 3D printer bodies, SLA 3D printers body include hollow cabinet and prolong upwardly along cabinet side
The support stretched, the bottom surface front end of cabinet is provided with laser scanning device, and the bottom surface center of the cabinet is provided with speculum, speculum
Surface is provided with resin storage tank, and the bottom surface of resin storage tank is installed with quartz glass thoroughly high, and quartz glass thoroughly high is fixedly arranged on iron plate, iron plate
It is fixedly connected with the motor in cabinet floor, cape is provided with directly over resin storage tank, support is provided with upright slide rail, cape
Slided up and down along the upright slide rail, also disclose its Method of printing.Compared with prior art, beaten described in foregoing invention application
The shaping speed of print machine is fast；The printer includes the drop-down mechanical structure for eliminating vacuum power, greatly improves yield rate, precision
Height, is particularly suitable for making required precision baroque prototype high；The printer arrangement is simple, easy to operate, substantially reduces
Production cost, can with large-scale promotion application.
By above-mentioned technical proposal, after the printer completes a printing action, cape is moved along on the upright slide rail,
Meanwhile, motor drives iron plate drop-down, and then drives resin storage tank to move down, and the vacuum in resin storage tank is eliminated by this drop-down action
Power, then motor drives iron plate pull-up, and then drives resin storage tank to move up, and carries out next printing action.
The content of the invention：
Technical problem solved by the invention：
First, SLA 3D printers of rapid shaping in the prior art, after completing a printing action, cape is along described
Moved on upright slide rail, meanwhile, motor drives iron plate drop-down, and then drives resin storage tank to move down, and is eliminated by this drop-down action
Vacuum power in resin storage tank, then motor drives iron plate pull-up, and then drives resin storage tank to move up, and carries out next printing dynamic
Make；An above-mentioned upper printing is acted to the cape action of the 3D printer between next printing action and resin storage tank lifting action
Carry out independently of one another, control process is complicated and is unfavorable for the accurate control of the resin flake thickness of product sectional profile；
Second, motor, if the process time is shorter, is unfavorable in resin storage tank by iron plate folding resin storage tank process once
