Description
Technical field
The present invention relates to a kind of quick liquid interface 3D print system, belong to printing technique field.
Background technology
General 3D prints, it is the technology manufacturing three-dimensional article by successively increasing material, this technology is the cutting edge technology combining the numerous areas such as digital modeling techniques, Electromechanical Control technology, information technology, material science and chemistry, and is described as the core technology of " the third time industrial revolution ".Wherein photocuring rapid prototyping technique, is also called photocuring 3D and prints fast shaping technology, have that energy consumption is little, cost is low, forming accuracy high, can print the part of any configuration complexity that traditional processing mode cannot be processed.Photocuring 3D prints the mode difference be shaped according to it can be divided into stereolithography (SLA), digital light process (DLP), three dimensional ink jet (3DSP) 3 kinds of modes.Wherein DLP and SLA Forming Theory is: the liquid photosensitive resin in accumulator tank after being light-cured into one deck thin layer along with objective table raise or reduce, use the same method again, on last cured layer, obtain a new cured layer, finally obtain the product of stereoscopic three-dimensional.SLA mainly adopts laser beam spot scanning that photosensitive resin is solidified, and as the 3D printer Form 1+ that Formlabs issues, minimum lift height reaches 25 μm; And the light source of DLP can be laser also can be high-pressure sodium lamp, xenon lamp etc., the method in the mode that face projects, photosensitive resin is solidified threedimensional model hierarchical Image, in layer solidifies and finally obtain 3D solid.
In sum, existing photocuring 3D printing technique is all solidification in layer, 3D entity is finally obtained by successively superposing, this method makes the precision of the goods printed be subject to the restriction of lift height, and the precision of the less goods of lift height is higher, but the required time-write interval is longer; In addition, traditional SLA and DLP photosensitive resin 3D printing technique, because cured layer is peeled off (printing from bottom to top) from resin storage tank inner bottom plating by photosensitive resin flow time long (printing from the top down) or needs machinery, causes printing interval long.Therefore, the application of this traditional 3D printing technique is by restriction to a certain extent.
Recently, Joseph's moral Simonyi (Joseph M. DeSimone) of the U.S. has invented a kind of " continuous liquid level growth " (Continuous Liquid Interface Production with his colleague's Alex Ye Ermoshijin (Alex Ermoshkin) and solemn Bielski (the Edward T. Samulski) cooperation of Edward's Sa, be called for short CLIP) technology, this technology utilizes light and oxygen inhibition, thus creates a kind of non-3D print procedure printed layer by layer.But, this control method is comparatively complicated, be only applicable to radically curing 3D printed photosensitive resin system, cationic curing 3D printed photosensitive resin system can not be used for, and relative to Cationic curing systems, radical-cured cure shrinkage is large, and the urethane cure shrinkage factor that " continuous liquid level growth " technology of being thus somebody's turn to do prints is larger.The report of domestic not relevant 3D printing continuously fast.
