Description
Technical field
The present invention relates to three-dimensional body manufacturing technology field, be specifically related to the three-dimensional manufacture of photosensitive resin material.
Background technology
Cubic light solidified forming is the photopolymerization principle work based on liquid photosensitive resin, is current more common 3D printing technique. Photocuring shaping system generally includes laser instrument, for holding the liquid bath of photosensitive resin, controller and a liftable object support platform. Liquid photosensitive resin is filled with in a liquid bath, scan under deflecting mirror effect by UV laser beam on liquid level, having or not by controller of the track of scanning and light controlled, the place that light beam shines, and liquid just solidifies. Be shaped while beginning, support platform is in the next definite degree of depth of liquid level, and the hot spot after focusing is instruction point by point scanning on liquid level, i.e. pointwise is solidified. After one deck has scanned, not irradiated place is still liquid resin. Then lifting platform drives the support platform layer height that declines, in the aspect of solidified forming, be covered with again one deck resin, strickle strikes off resin liquid level larger viscosity, and then carry out the scanning of lower one deck, new curing one deck is bonded on front one deck securely, so repeat, until the manufacture of whole three-dimensional body is complete, to obtain a 3D solid.
After resin solidification, again a kind of method that applies curing resin layer with new resin is that support platform is immersed in liquid resin, support platform drops to the distance that is greater than predetermined bed thickness under the surface of resin liquid vertically, to apply the layer after solidifying with new liquid resin. This system is increased to support platform a bed thickness under resin surface. Excessive liquid resin flows away and is flattened to single bed thickness by gravity. After this, laser applies energy to working surface.
The stand-by period that excessive liquid resin flows away and thin layer flattens is depended on several factors and changes, comprising the viscosity of polymerizable liquid, bed thickness, the combination shape of parts, cross section etc. Resin can also use scraper to help flatten, and scraper skims over the surface of resin, this with in the groove that holds resin, by gravity, resin working face deposition is compared with flattening, this can apply quickly new resin and remove excessive resin.
But, realize by resin fluid self gravitation and by scraper the method that thin layer flattens, the most of the time of the three-dimensional body manufacture process that still accounted for, and being still difficult to obtain the uniform thin layer of bed thickness in order to guarantee the dimensional accuracy of object by scraper, these influence factors have lengthened object manufacturing time, have reduced productivity ratio, have improved manufacturing cost.
Summary of the invention
The problem existing in order to solve prior art, the invention provides a kind of groove of the system of manufacturing three-dimensional body and system thereof, method, can obtain stable resin liquid level by the present invention, thereby prepare the uniform three-dimensional body thin layer of bed thickness, can also reduce resin-coating liquid level and flatten the needed time simultaneously, thus manufacture efficiency and the accuracy of manufacture of raising three-dimensional body.
