Abstract
The utility model discloses a 3D printer based on continuous ultraviolet photocuring technique, by work platform, the container, apparatus of oxygen supply and image device constitute. The container bottom is transparent, can upwards see through oxygen and ultraviolet ray, is equipped with liquid resin in the container, the apparatus of oxygen supply is followed the container bottom and is upwards provided oxygen, utilizes hindering of oxygen to gather the effect and forms a stable not solidifiable layer (lasting the liquid interface) in the bottom of container, image device follows the container bottom and upwards shines the ultraviolet ray, makes the resin curing shaping of not solidifiable layer top. Work platform above lieing in the container drives when fashioned model has upwards spurred, and the liquid resin on not solidifiable layer can make progress rapidly and flow, replenishes the vacuum that the model pull -up formed, realizes continuous shaping. The utility model discloses comparing prior art, having high 3D print speed and precision, can print the wide range of solid, the surface quality who prints the solid is high.
Description
Technical field
The utility model relates to the technical field that 3D prints, and particularly relates to a kind of 3D printer continuously shaped fast.
Background technology
At present, the operation principle of the existing 3D printer about photosensitive resin curing molding technology is the light polymerization based on liquid photosensitive resin.When shaping beginning, the degree of depth that workbench pallet is determined at the liquid level next one, light presses instruction point by point scanning and the pointwise solidification of computer on liquid level.After one deck has scanned, workbench moves down, in type aspect is covered with again one deck liquid resin, resin liquid level larger for viscosity strikes off by scraper plate, and then carrying out the scanning of lower one deck, new one deck solid is bonded on front one deck securely, so repeats, print target object by the mode successively printed, print speed is slow; The precision of this technology can reach or be less than 0.1mm; Spendable material category is less, and material available is at present mainly photonasty liquid resin material; Need regelate, under many circumstances, the prototype resin after rapid prototyping system photocuring is not completely by laser curing; Product is more flexible, needs to support, otherwise product can be caused to be out of shape.
Therefore need a kind of scheme to solve above-mentioned shortcoming.
Summary of the invention
In order to improve speed and the precision of 3D printing, increase the use kind of 3D printed material, expansion can print the scope of solid, the utility model provides a kind of 3D printer based on continuous ultraviolet photo-curing technology, this 3D printer utilizes the inhibition effect of oxygen, in the middle of liquid level, be built into profile, overcome model pull-up and form vacuum, hinder the problem of solidification continuously; The continuous ultraviolet photo-curing technology that this 3D printer adopts simultaneously makes a series of material can be used to create the 3D part with new features, comprises elastomer, silicone, the material of similar nylon, pottery and Biodegradable material; Except using new material, this technology can also create that other technology cannot realize, there is unique geometric more firmly object.
The technical scheme that the utility model adopts is: a kind of 3D printer based on continuous ultraviolet photo-curing technology, and this technology utilizes the inhibition effect of oxygen, in the middle of liquid level, be built into profile, overcomes model pull-up and forms vacuum, hinder the problem of solidification continuously; By workbench, container, apparatus of oxygen supply and imaging device composition.Described container bottom is transparent, can upwards through oxygen and ultraviolet, and container content has liquid resin; Apparatus of oxygen supply upwards provides oxygen from container bottom, utilizes the inhibition effect of oxygen to form a stable not curable layer (continuing liquid surface) in the bottom of container; Imaging device, from container bottom upwards irradiation ultraviolet radiation, makes the resin generation curing molding above not curable layer.When being positioned at the workbench above container and driving in type model upwards to pull, the liquid resin of curable layer can not be rapidly to flowing, the vacuum that supplementary model pull-up is formed, and realizes continuously shaped, greatly can improve speed and the surface quality of photocuring.Move on described workbench is continuous in forming objects process.
Compared with background technology, difference of the present utility model is the centre that forming surface is positioned at liquid, utilize the inhibition effect of oxygen, liquid can space after continuous supplementation model pull-up, make object to result from liquid medium, supplement one deck technology sooner much than shaping one deck, the resin velocity of complicated solid portion reaches hundreds of millimeter per hour, the large I of some feature is less than 20 microns, or also thinner than 1/4 of a piece of paper thickness.This technology makes elastomer, silicone, the material of similar nylon, pottery and Biodegradable material can be used to create the 3D part with new features simultaneously, this technology can also create that other technology cannot realize, there is unique geometric more firmly object.
Accompanying drawing explanation
Fig. 1 is the principle schematic of a kind of 3D printer based on continuous ultraviolet photo-curing technology of the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing and concrete embodiment, the utility model is further illustrated.These embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
Refer to Fig. 1, the utility model discloses a kind of 3D printer based on continuous ultraviolet photo-curing technology, by workbench 1, and container 2, apparatus of oxygen supply 3 and imaging device 4 form; Described workbench 1 is positioned at above container 2, and apparatus of oxygen supply 3 and imaging device 4 are positioned at the below of container 2.
Refer to Fig. 1, transparent bottom described container 2, can upwards through oxygen and ultraviolet, container 2 is built with liquid resin; Apparatus of oxygen supply 3 upwards provides oxygen bottom container 2, utilizes the inhibition effect of oxygen to form a stable not curable layer (continuing liquid surface) in the bottom of container 2; Imaging device 4 upwards irradiation ultraviolet radiation bottom container 2, makes the resin generation curing molding above not curable layer.
Consult Fig. 1, move, when driving in type model upwards to pull on described workbench 1 is continuous in forming objects process, the liquid resin of curable layer can not be rapidly to flowing, the vacuum that supplementary model pull-up is formed, realizes continuously shaped, greatly can improve speed and the surface quality of photocuring.
