Description
Technical field
The utility model relates to a kind of 3D Xograph machine equipment, can duplicate three-dimensional body, obtains a 3D Xograph part.
Background technology
At present, plane reprography is very ripe, is no matter the figure of plane, image or word, can duplicates, and can also carry out color photocopying with duplicator.But, how can carry out Xograph, or a still unsolved technical problem.
On the one hand, now existing stereoscan technology, can obtain the computer data of three-dimensional body by stereoscan, processes, obtain 3 D stereo SLT file to these threedimensional models in computer.On the other hand, along with the appearance of 3D printing technique, there is a variety of mode to realize 3 D stereo and print, such as photocuring technology (StereoLithographyAppearance, be called for short SLA), be the rapid prototype manufacturing technique that occurs the earliest 3D printing technique the earliest in other words conj.or perhaps.SLA technology light source used is laser, has the advantages that wavelength is single, spot size is little and power density is large, by accurate gated sweep head, can realize part degree, high accuracy is shaped.But existing SLA system is complicated, and laser irradiates from the top down, in forming process, in order to ensure the flatness of resin liquid finished surface, needing complicated device to go regulating liquid surface flatness, make total system volume excessive and involve great expense; For this reason, be developed small-sized desktop type SLA, laser upwards irradiates from bottom, has occurred the shadow casting technique of digital light process DLP in recent years, is upwards project from bottom.The mode that can be projected by face is by resin solidification in forming process, and the curing mode of this exposure, than SLA by putting line, then by line to face, then curing rate improves greatly layer by layer.It is needs resin storage tanks, pours in resin storage tank in advance by resin, and illumination is penetrated resin and made resin solidified forming layer by layer.But all adopt the mode printed layer by layer to realize due to current these 3D printing techniques, along with the minimizing of lift height, print the number of plies and increase, the time-write interval is very long, and usual print procedure all wants a few hours consuming time.Other 3D printing techniques also have such as 3DP (3 D stereo printing), SLS (precinct laser sintering) and SLM (precinct laser fusion) etc.
Based on above consideration, we utilize 3-D scanning and 3D printing technique to combine, and invent this Xograph machine.The utility model is the once innovation in essence to existing plane duplicator, will greatly promote the development of reprography.
Summary of the invention
3D stereoscan technology combines with 3D printing technique by the utility model, use 3D stereoscan instrument, by 3 d object scanning, obtain the computer data of three-dimensional body, then by computer, layering is carried out to three-dimensional computations machine data, then utilize 3D printing technique, by three dimensional model printing out, realize the object that 3D duplicates.In order to shorten the duplicating time, using scanning to carry out 3-D scanning, using 3D printing technique, carry out 3D printing shaping.Whole copying process can complete in several tens minutes.
3D Xograph machine, is characterized in that: comprise the 3D stereoscan instrument and 3D three-dimensional printing machine that are connected with computer; 3D printer is the 3D printer of desktop type.
Further, 3D three-dimensional printing machine printed material is nonmetallic materials.
The application process of described 3D Xograph machine, is characterized in that: when starting to duplicate, carries out 3D stereoscan to three-dimensional body.Computer carries out layered shaping to 3D data after obtaining 3D stereo data, then by layered data transport to 3D three-dimensional printing room, carry out 3D printing in 3D three-dimensional printing room, obtain the three-dimensional body consistent with three-dimensional body profile to be copied.
Further, 3D three-dimensional printing machine is not selected the 3D printer of desktop type but is selected another program.Comprise 3D stereo projection system, resin box and computer-controlled laser instrument; By x, y scanning galvanometer, 3D stereo projection system adds that the galvanometer of Z-direction forms; Resin box is that the transparent material of surrounding is made, and photosensitive resin is poured in resin box in advance; Be transparent liquid under described photosensitive resin normal temperature, only penetrate and threshold value that light intensity exceedes its solidification could be solidified and solidified in illumination.
When printing beginning, first in resin box, photosensitive resin is filled, then 3D stereo projection system is opened, laser light resin box, be radiated on photosensitive resin, in resin, form 3D picture, control the exposure curing time by computer, photosensitive resin is subject to laser and irradiates and light intensity exceedes the part generation photochemical reaction after coagulation of threshold value of its solidification, and the part be not irradiated to is still liquid resin; Solidify and " printing " goes out 3D resin mould.
Further, irradiation time is longer, and resin solidification intensity is higher.
Further, laser is visible laser.
Further, laser is the green laser of wavelength at 530nm, or wavelength is the red laser of 800nm.
Operation principle of the present utility model: this 3D Xograph part has two cores, one is 3D stereoscopic scanning system, one is 3D print system, 3D stereoscopic scanning system adopts 3D scanning technique general at present, by project structured light on object, take, obtain the three-dimensional computations machine data of object.3D print system then adopts Stereolithography 3D printer, completes the printing speed of 3D data fast.These two systems are all controlled by computer control system.Before duplicating starts, can copy size be set, such as copies according to 1:1 or M:N.Duplicating quality can be set, such as meticulous, general, coarse.Focus on galvanometer by this system by x, y scanning galvanometer and Z axis to form.Light, through x, y scanning galvanometer, can form a plane picture, and plane picture forms one 3 dimension stereo-picture under the focusing galvanometer effect of Z-direction.Before starting to print, in photosensitive resin groove, fill transparent photosensitive resin liquid, and slicing treatment acquisition 3D model is carried out along a series of x, the y panel data of Z-direction along Z-direction to the 3D model in computer; After printing starts, laser under the control of the computer, focuses on galvanometer along the scanning galvanometer in xy direction and Z-direction and forms a 3D stereo-picture in space.Projected by this 3D stereo-picture in transparent photosensitive resin groove, owing to using transparent liquid photosensitive resin, laser beam can through photosensitive resin, and focusing illumination is to the inside of resin.Laser beam does not reach threshold value solidification needed for through photosensitive resin due to light intensity at focus place, therefore any reaction can not occur, only in the focus place energy density of laser higher than the place of solidification threshold value, resin is just cured and solidifies.Along with the increase of irradiation time, the intensity at resin solidification place also constantly increases.The resin solidification at laser spot place solidifies, and the resin not at focus place still keeps liquid.After having solidified, from resin, take out the 3D model of curing molding, complete printing.
Technical characteristic of the present utility model:
1., before printing, on the turntable that the object of " duplicating " is placed in 3D scanning chamber, carry out 360 degree of rotations by treating.
2.3D scanning employing wavelength is the green laser of 532nm is structured light, with two cameras shootings.
3., when object rotates, each face of camera shot object, obtains 3D data;
4. computer carries out slicing treatment to 3D data along Z-direction, obtains a series of two-dimensional slice image along Z-direction;
5. by this series of two-dimensional slice image according to certain ratio, be input in 3D printer.
6.3D printer receives data and carries out 3D printing acquisition a certain proportion of " autotype ".
