In order to solve the above technical problems, the present invention provides following technical scheme：A kind of 3D printing based on 405nm wavelength
Method, it is characterised in that comprise the following steps：
A, photosensitive resin is placed in print cup, establishes three-dimensional entity model using computer, setting is vertically given birth to
Thickness and each layer scanning pattern program into cross section stratified model；
B, print routine is started, laser generator carries out first layer cross section stratified model according to the scanning imaging system set
Laser irradiation printing, complete first layer printing；The light wave of laser irradiation is 405nm wavelength；
C, lifting working platform vertically declines, and scraper is moved once, and the photosensitive resin in print cup is applied to
Current layer surface, the height of decline is the thickness of cross section stratified model, and carries out the printing of next layer of cross section stratified model；
D, repeat step C, product is obtained.
A kind of 3D printing method based on 405nm wavelength as described above, it is characterised in that described laser generator
It is arranged on the top of print cup.
A kind of 3D printing method based on 405nm wavelength as described above, it is characterised in that set in described print cup

Compared with prior art, a kind of 3D printing method based on 405nm wavelength of the invention, have following beneficial to effect
Fruit：
The present invention is solidified using 405nm wavelength to photosensitive resin, is applied each layer of resin to cover using scraper, is successively beaten
Print, simple in construction, no material consumption, and cost is saved, reduce technology difficulty.
【Brief description of the drawings】
The embodiment of the present invention is described in further detail below in conjunction with the accompanying drawings, wherein：
Fig. 1 is the installation drawing for implementing the present invention.
Brief description of the drawings：1st, print cup；2nd, photosensitive resin；3rd, laser generator；4th, lifting working platform；5th, scraper；6th, make
Part.
【Embodiment】
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes.
Embodiment
As shown in figure 1, in the present embodiment, a kind of 3D printing method based on 405nm wavelength, comprise the following steps：
A, photosensitive resin 2 is placed in print cup 1, establishes three-dimensional entity model using computer, set vertically
Generate the thickness of cross section stratified model and each layer scanning pattern program；
B, print routine is started, laser generator 3 carries out first layer cross section stratiform mould according to the scanning imaging system set
The laser irradiation printing of type, completes first layer printing；The light wave of laser irradiation is 405nm wavelength；The photosensitive resin of 405nm wavelength
Performance can reach real ABS materials, the soft material performance of 200 degree of high temperature resistant and silica type.
C, lifting working platform 4 vertically declines, and scraper 5 moves once, and the photosensitive resin 2 in print cup 1 is applied
It is put on current layer surface, the height of decline is the thickness of cross section stratified model, and carries out next layer of cross section stratified model
Printing；
D, repeat step C, product 6 is obtained；The present invention is consolidated using 405nm wavelength under conditions of aerobic to photosensitive resin
Change, apply each layer of resin to cover using scraper, successively printed, simple in construction, no material consumption, and save cost, reduce work
Skill difficulty.
As shown in figure 1, in the present embodiment, described laser generator 3 is arranged on the top of print cup 1.The present invention's
Printing can be printed under aerobic environment, i.e., carry out liquid level levelling by the way of coating, laser generator now is set
Put in the top of print cup 1；
It can certainly be printed in the Environmental of anaerobic, laser generator now should be arranged under print cup
Side is irradiated printing to print cup, and mode is not especially limited herein.
As shown in figure 1, in the present embodiment, liquid level regulation device is provided with described print cup 1, by print cup 1
Liquid smoothly maintain certain value.
Specific printing flow is as follows：
A, designed a model using the Three-dimensional Design Software such as UG, SOLIDWORKS, 3D MAX, Pro/E, model is exported into STL
The unilateral file of triangle of form, threedimensional model is converted into multiple two-dimensional models using section file.
B, the two dimensional model file set after changing is imported in 3D printer, and lifting working platform is by setting thickness in figure
Degree, is successively moved, the X-Y scheme shape after current layer is changed threedimensional model by scanning system is drawn, now
Laser is sketched out a sheet of planar figure by scanning system according to the shape of X-Y scheme on lifting platform, liquid material quilt in print cup
After laser irradiation, solid-state is become by liquid.
C, after step B process, one layer of shaping is completed.Self-powered platform declines one layer, and scraper moves once, will
The liquid material of print cup is applied to current layer article surface.
D：Scanning system will irradiate laser once again according to the X-Y scheme changed in current layer, then by step
C process, until model prints completion completely.
