Description
Technical field：
The present invention relates to 3D printer technical field, in particular to 3D printer and its Method of printing.
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 by the information transmission of these sections to 3D
On printer, continuous slim aspect can be stacked up 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.
Stacking the form of thin layer has varied.Some 3D printers use the mode of " ink-jet ".For example, one entitled
Objet 3D printer company of Israel 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 handled 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, is then solidified by the fluid binder sprayed.It can also use one kind to be called " laser sintered "
Technology founding into designated shape.This technology that also exactly German EOS Corp. uses in its superposition process manufacturing machine.And Switzerland
Arcam companies then be utilize vacuum in electron stream fusing powder particle.Above-mentioned these are only many shaping sides
A part in formula.When running into comprising labyrinth as hole and cantilever, be accomplished by adding in medium 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.The principle solidified based on photosensitive resin by ultraviolet light, computer control is swashed
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 prototype in kind.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 still can not be general main compared with real manufactured goods in terms of intensity
For in terms of prototype checking, rapid prototyping then to be converted into technical grade product by a series of subsequent treatment processes.This
Outside, 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.
Application No. CN201410461645.5 application for a patent for invention discloses a kind of SLA 3D printings of rapid shaping
Machine, including SLA 3D printer bodies, SLA 3D printers body upwardly prolong including hollow cabinet and along cabinet side
