Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
Embodiment: as Figure 1-3, the utility model provides a kind of photosensitive resin 3D printer being light source with LED array battle array, comprise LED matrix 1 and print platform lowering or hoisting gear 3, the top movable of described LED matrix 1 connects LED horizontal mobile mechanism 2, described print platform lowering or hoisting gear 3 is fixedly connected with print platform 6, the below of described print platform lowering or hoisting gear 3 is provided with resin storage tank 4, and described resin storage tank 4 is built-in with liquid photosensitive resin 5, and the top of described print platform 6 is for placing printing objects 7.
Described LED matrix 1 is one group of intensive emitting led diode array, is that then optical signal is transmitted on liquid photosensitive resin 5 and makes photosensitive resin be subject to photocuring by the transform electrical signals of data message.LED matrix 2 moves along the horizontal direction perpendicular to LED array while scanning, and so forms on photosensitive resin 5 surface the figure needed.
Before printing, being printed the three-dimensional file input computer of article 7, computer program can according to user need figure rotated, move, change in size, add support etc., then solid figure is cut into slices, Formation cross-section figure like this, the translational speed of LED array when determining that the quantity in section thickness and cross section, simultaneous computer program are also determined to print.
Described LED matrix 1 is parallel to print platform 6 and liquid photosensitive resin 5 surface, and described LED horizontal mobile mechanism 2 is perpendicular to print platform lowering or hoisting gear 3, and described print platform lowering or hoisting gear 3 is perpendicular to print platform 6 and liquid photosensitive resin 5 surface.
The course of work, print platform 6 first immerses in liquid photosensitive resin 5 downwards, then is lifted to lower than the certain distance of the upper surface of liquid photosensitive resin 5, so just defines skim liquid photosensitive resin 5 on the surface of print platform 6.Then LED matrix 1 by the side of resin storage tank 4 to opposite side uniform motion;
When move in ground floor serial section as shown in Figure 4 have figure local time, in LED array, corresponding LED starts to irradiate, such as: when printing to the left wall of square frame, liquid photosensitive resins 5 are irradiated in middle some continuous print LED matrixs 1 luminescences;
As shown in Figure 5, when LED matrix 1 moves, according to the change of sectional view, the retroreflective regions of LED adjusts in real time.Such as, terminate when left wall prints, when starting to print both sides, LED light Shu Bianwei two segment;
As shown in Figure 6, when LED array continues mobile, the light-emitting zone of LED continues to adjust in real time.
After the first thin layer printing terminates, print platform 6 immerses downwards in liquid photosensitive resin 5 again, then lifting, but lifting distance is more lower slightly than first time lifting, lower slightly degree is equivalent to the thickness of the second thin layer, so just make the upper surface of the liquid photosensitive resin layer had cured on print platform be lifted to lower than the certain distance of liquid photosensitive resin 5 upper surface, thus the surface of the liquid photosensitive resin layer had cured on print platform 6 define second layer liquid photosensitive resin thin layer.Then LED light source by the side of resin storage tank 4 to opposite side uniform motion, when move in second layer serial section have figure local time, in LED array, corresponding LED starts to irradiate, so the second width graph scanning on the liquid photosensitive resin thin layer of print platform, be subject to the liquid photosensitive resin then curing molding of illumination, form second cross section of object.Then LED light source gets back to original position.So go round and begin again, photosensitive resin solidifies from level to level, until form the stereo article needed.
The another kind of molding mode of the utility model: the resin storage tank that liquid photosensitive resin is housed is positioned at top, the bottom of resin storage tank is one piece of antiseized transparent plate, and LED array is positioned at below resin storage tank, and the light that LED sends can irradiate photosensitive resin through transparent plate.Print platform is in resin storage tank.When printing ground floor, first print platform moves to the dull and stereotyped very near position of distance transparent, forms photosensitive resin thin layer between print platform and transparent plate.Then LED by the side of resin storage tank to opposite side uniform motion, when move in ground floor serial section have figure local time, in LED array, corresponding LED starts to irradiate, so a view picture graph scanning on the photosensitive resin thin layer of print platform, be subject to the photosensitive resin then curing molding of illumination, form a cross section of object.Then LED light source gets back to original position.Print platform lifting certain distance, makes the photosensitive resin of solidification leave transparent plate, and then print platform decline certain distance makes transparent platform to be formed second layer photosensitive resin thin layer.LED light source by the side of resin storage tank to opposite side uniform motion, when move in second layer serial section have figure local time, in LED array, corresponding LED starts to irradiate, so the second width graph scanning on the photosensitive resin thin layer of print platform, be subject to the photosensitive resin then curing molding of illumination, form first cross section of object.Then LED light source gets back to original position.So go round and begin again, photosensitive resin solidifies from level to level, until form the stereo article needed
The utility model intensity of illumination is even, print speed is fast; Photosensitive resin 3D printer, rapidform machine intensity of illumination in whole print range can be made to preserve consistent, improve printing precision, the article surface printed is bright and clean, and simplifies frame for movement and the control program of 3D printer (rapidform machine), extends light source life.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
