Abstract
The present invention provides a kind of photocuring 3D printing techniques of adjusting exposure intensity control properties of product, by the way that three dimensional file is placed in computer program, three dimensional file is sliced using computer program, obtain luminance information, time for exposure and the exposure color of the size and figure in each each section of slice everywhere, by photocuring 3D printer, in printing, control brightness, time for exposure and exposure these three parameters of color are to be adjusted the exposure intensity of each section corresponding position of printed matter again, to change the physical property of printed matter.The present invention by real time adjust 3D printing during printer provide exposure intensity, so that photosensitive resin is generated different elasticity modulus, modulus of shearing, stretch modulus and color when solidifying, make photocuring printing technique more comprehensively, more scientific, practicability is stronger.
Description
Technical field
It is specially a kind of to change printed matter physical property by adjusting exposure intensity the present invention relates to 3D printing field
Photocuring 3D printing technique.
Background technique
Normal printer is often used in daily life, can be used to the flat objects of printing calculator design.And institute
The 3D printer of meaning and the working principle of normal printer are essentially identical, and the material only printed is somewhat different.Normal printer
Printed material be ink and paper, and 3D printer is provided with different " printed materials " such as metal, ceramics, plastics, sand.It beats
After print machine is connect with computer, " printed material " can be stacked up in layers by computer control, finally on computer
Blueprint become in kind.Generally, 3D printer is a kind of equipment that " can print " true 3D object.It can be used to
Printer device people, toy car and various models, or even can also be food.Why be generically called " printer " be because
The technical principle of normal printer is had references to for it, and the process of layering processing and inkjet printing are also quite similar.3D printer
There are many kinds of the forming techniques of use, such as: stereolithography apparatus method, melt-laminated molding technology, selective laser sintering
Deng.Stereolithography apparatus method is high, high-quality by formed precision, and higher reputation is enjoyed in 3D printing field.The technology
It is mainly radiated at the surface (material is mainly resin) of photo-curing material using the light of certain strength, is allowed to complete on a layer
Print job, one layer complete after carry out next layer, move in circles, until be finally completed works.Currently, common in the market
3D printer is exactly directly to be printed simply by three dimensional file, and printed matter structure is single, dull coloring.Especially making
When complex object, normal printer, which can only be imitated simply, replicates its structure, and can not provide different needed for each structure
Physical property, leads to that printed matter fragile structure, the practicability is poor, and can not manufacture color body.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the existing defects, and the physical of printed matter can be parsed by providing one kind
Matter directly makes the 3D printing technique of the printing shaping of object comprising different physical characteristics.
In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions:
A kind of photocuring 3D printing technique adjusting exposure intensity control properties of product, comprising steps of
1) it by the three dimensional file merging computer program for needing to print, is handled；
2) computer program is sliced three dimensional file, and parse it is each be sliced its each section dimension of picture and
Luminance information, time for exposure and the exposure color of figure everywhere；
3) three dimensional file being parsed is printed by photocuring 3D printer；
4) photocuring 3D printer passes through figure brightness everywhere, time for exposure and exposure color these three ginsengs in printing
Number adjusts the exposure intensity of each section corresponding position of printed matter in real time, changes the physical property of printed matter.
Further, photocuring 3D printer is built-in receives program.
Further, it receives program to match with computer program, resolution file can be interpreted.
The beneficial effects of the present invention are: the exposure intensity that (1) is provided by printer during change 3D printing, makes photosensitive
Resin generates different elasticity modulus, modulus of shearing, stretch modulus and color when solidifying, and makes photocuring printing technique more comprehensively
It is more scientific, practicability is stronger；(2) technically simple, straight forming is printed, complex-shaped object, printed matter structure can be printed
It is firm, it is more durable；(3) computer program is researched and developed specifically for three dimensional file, obtains product institute by parsing three dimensional file
The physical property needed, then printed by the reception program built in photocuring 3D printer, it complements each other, scientific design makes
Printing is more accurate, and printing effect is more perfect.
Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described, it should be understood that preferred embodiment described herein is only used
In the description and interpretation present invention, it is not intended to limit the present invention.
In photocuring 3D printing technique, photosensitive resin is illuminated by the light and solidifies, by printing final molding layer by layer.It is printing
In the process, the light energy received since photosensitive resin is practical is different, elasticity modulus, modulus of shearing after solidifying, stretching
Modulus, color etc. all can be different.Therefore, it is possible to control solidfied material by the actual exposure energy for controlling photosensitive resin
The physical property of body.
A kind of photocuring 3D printing technique adjusting exposure intensity control properties of product of the present invention, is based on above-mentioned feelings
Condition carries out exploitation design.The overall design thinking of the technology is, firstly, three dimensional file merging computer program will be needed to beat
In, it is handled by computer program.The computer program is specific to what three dimensional file was researched and developed, can incite somebody to action
The printed matter provided in three dimensional file is sliced." by printing layer by layer most when this slice is equal to the printing of common photocuring
" layer " in final shaping unit ".Then computer program can obtain each cut according to the information parsing slice for including in three dimensional file
Luminance information, time for exposure and the exposure color of the size and figure in its each section of piece everywhere, to subsequent printing.Solution
After the completion of analysis, connection photocuring 3D printer is printed.It is built-in with reception program in photocuring 3D printer, the reception program
To each position of printed matter when can obtain the parsing information that computer program finally provides, and be printed by the control of these information
The exposure intensity given, to complete to print.
Steps are as follows for the realization of the technology:
1) it by the three dimensional file merging computer program for needing to print, is handled；
2) computer program is sliced three dimensional file first, and parse it is each be sliced its each section dimension of picture,
And luminance information, time for exposure and the exposure color of figure everywhere；
3) three dimensional file being parsed is printed by photocuring 3D printer；
4) photocuring 3D printer passes through figure brightness everywhere, time for exposure and exposure color these three ginsengs in printing
Number adjusts the exposure intensity of each section corresponding position of printed matter in real time, changes the physical property of printed matter.
It should be noted that in an embodiment of the present invention, photocuring 3D printer is conventional products, do not have to its specification
