Description
Technical field
The present invention relates to the technical field of rapid shaping, particularly relate to a kind of continuous shaping method for rapid shaping.
Background technology
At present, existing rapid shaping photosensitive resin curing molding technology is photopolymerization principle based on liquid photosensitive resin work.When molding starts, the degree of depth that work platforms pallet determines at the liquid level next one, light presses the instruction point by point scanning i.e. pointwise solidification of computer on liquid level.After one layer of scanning completes, work platforms moves down, one layer of liquid resin it is covered with again in type aspect, resin liquid level bigger for viscosity is struck off by scraper plate, carrying out the scanning of next layer the most again, one layer of new solid is firmly sticked in preceding layer, so repeats, printing target object by the way of successively printing, print speed is slow；The precision of this technology can reach or less than 0.1 mm；Spendable material category is less, is currently available that material is mainly photonasty liquid resin material；Needing secondary to solidify, under many circumstances, the prototype resin after rapid prototyping system photocuring is the most completely by laser curing；Product is more flexible, needs to support, product otherwise can be caused to deform.
Therefore need a kind of technology to solve disadvantages mentioned above.
Summary of the invention
In order to improve speed and the precision of rapid shaping, increase the use kind of rapid prototyping material, expansion can print the scope of solid, the present invention provides a kind of continuous ultraviolet photo-curing method for rapid shaping, the method utilizes the inhibition effect of oxygen, in the middle of liquid level, it is built into profile, overcomes model pull-up to form vacuum, the problem hindering solidification continuously；This technology makes a series of material can be used for creating the 3D part with new features simultaneously, including elastomer, silicone, the similar material of nylon, pottery and Biodegradable material；Except using new material, this technology can also create that other technology cannot realize, there is unique geometric stronger object.
The technical solution adopted in the present invention is: a kind of continuous ultraviolet photo-curing method for rapid shaping, and the method utilizes the inhibition effect of oxygen, is built into profile in the middle of liquid level, overcomes model pull-up to form vacuum, the problem hindering solidification continuously；By work platforms, container, apparatus of oxygen supply and imaging device composition.Described container bottom is transparent, can upwards pass through oxygen and ultraviolet, and container content has liquid resin；Apparatus of oxygen supply provides oxygen from container bottom up, utilizes the inhibition effect of oxygen to form a stable inhibition layer (continuing liquid surface) in the bottom of container；Imaging device, from container bottom up irradiation ultraviolet radiation, makes the resin generation curing molding above inhibition layer.When being positioned at the work platforms above container and driving in type model to pull up, the liquid resin of inhibition layer can flow rapidly upward, and the vacuum that supplementary model pull-up is formed, it is achieved continuously shaped can be greatly improved speed and the surface quality of photocuring.Move on described work platforms is continuous during forming objects.
Compared with background technology, the difference of the present invention is the centre that forming surface is positioned at liquid, utilize the inhibition effect of oxygen, liquid can continuous supplementation model pull-up after space, making object can result from liquid medium, more a lot of soon than molding one layer is supplemented with a layer method, the resin velocity of complicated solid portion reaches the most hundreds of millimeter, the size of some feature is smaller than 20 microns, or thinner than the 1/4 of a piece of paper thickness.This technology makes elastomer, silicone, the similar material of nylon, pottery and Biodegradable material can be used for creating the 3D part with new features simultaneously, this technology can also create that other technology cannot realize, there is the geometric stronger object of uniqueness.
