Background technology
Rapid shaping technique is (also known as rapid prototyping technique, RapidPrototypingManufacturing, it is called for short RPM), printing also known as 3D, be based on the high-new manufacturing technology of one that material successively adds up, it is layered according to the three-dimensional data model of part or object, obtain the profile of each layer, calculating machining path, printhead obtains the entity of each layer under control of the control system according to machining path simultaneously, obtains total entity eventually through each layer stacking.
Different from printed material according to printing type, 3D printing technique can be divided into different kinds.The 3D printing technique of current main flow has SLA, FDM, 3DP, SLS, SLM, LOM etc., SLA(Stereolithography technology in these techniques) it is most widely used, formed precision is of a relatively high, the Stereolithography principle of SLA is to utilize ultraviolet laser solidification that the highstrung liquid resin material of ultraviolet light is shaped, it is layered cross section information through over-focusing UV laser beam according to part under the control of the computer and liquid resin surface is carried out pointwise line scanning, the resin in scanned region produces photopolymerization reaction instantaneous solidification, form a thin layer, after solidifying when one layer, workbench moves down a thickness, liquid resin covers the liquid resin of a work thickness automatically at cured piece surface, and then carry out next layer of scanning to solidify, so repeatedly until whole part prints complete.But, SLA uses point source, and by point to line again to the molding mode in face, shaping speed is slower.
Problem for existing SLA Stereolithography, propose DLP projection photocurable forming technique, DLP is the abbreviation of " DigitalLightProcession ", it is digital light to process, that is this technology wants elder generation signal of video signal through digital processing, then again optical projection out, it is based on TI(Texas Instruments) company exploitation digital micromirror elements DMD(DigitalMicromirrorDevice) complete the technology that viewable numbers information shows.DLP projection photocurable forming technique uses the Digital Light Processor (DLP) of a kind of high-resolution to solidify liquid photopolymer, from level to level liquid polymer is solidified, moves in circles with this, until completing of final mask.Existing DLP technology, is generally static DLP shadow casting technique, and namely DLP projector is fixed on pedestal, and DLP projector does not move, and when exposing for every layer, is projected out corresponding image, keeps corresponding time of exposure, complete the solidification of every layer.
The structure of current DLP photocuring printer all must arrange a radical occlusion device between resin storage tank and scialyscope, in order that protection photosensitive resin can not be subject to the irradiation of projected light in the non-print stage and cause aging, generally this light-baffling device is all drive light barrier rectilinear movement by servomotor or in rotary moving play an effect being in the light, publication No. be CN204773621U patent documentation in disclose the DLP projector camera lens radical occlusion device of a kind of 3D photocuring printer, motor is adopted to drive rotational lead screw motion that projector lens shielding plate automatic rotation is blocked camera lens, avoid light source contacts liquid photosensitive resin.This radical occlusion device is taken up space relatively big, affects global formation space, and response speed is slow, and structure is complicated.
