Explanation.
As shown in Figure 1, photocuring 3D printing equipment is mainly by being that carrier 1, optical clear component 2, radiation source 3 form,
Wherein optical clear component 2 has Stereolithography face 6, is three-dimensional article fabrication region between carrier 1 and Stereolithography face 6,
Polymerizable liquid 4 fills three-dimensional article fabrication region, and radiation source 3 provides radiation energy to three-dimensional fabrication region, receives radiation
Polymerization reaction occurs for part polymerizable liquid 4, and cured 3D printing part 5, the carrier 1 are then formed on the surface of carrier 1
It is connected with mechanical actuation device, carrier 1 moves to the direction far from Stereolithography face 6 and drives 5 (polymerizable liquid of 3D printing part
After 4 photocurings) make that there is new molding space between Stereolithography face 6 and 3D printing part 5, polymerizable liquid 4 flows back into
Behind Stereolithography face 6, it is further continued for receiving radiation and is solidified, successively manufacture in this way, until 3D printing is completed.
By above-mentioned photocuring 3D printing equipment be used for it is of the present invention using multi-wavelength light carry out 3D printing, using stream
Journey is divided into three categories, including printing prepares, print procedure and printing post-processing, specific steps flow chart can refer to Fig. 2, wraps
It includes:
Printing prepares
Step 101, first by the 3D model import slices software of pre-print, and by slice of data input radiation source, specifically
The mode of slice can be the high slice of same layer, i.e. every layer of the print time is identical, is also possible to the structure according to 3D model
Feature carries out change layer height slice, i.e., every layer of print time is different, and the high slicing mode of same layer is suitable for structure more rule
3D model, the high slicing mode of change layer are suitable for the 3D model of irregular structure, and radiation source therein issues radiation scope 7 every time
It is corresponding with the pattern that every layer is sliced, it can specifically be realized by DLP technology or transparent LED display, i.e. radiation source
For ray machine, which has DLP chip, and DLP chip has imported slice of data, and light can be with regard to number of slices after passing through the DLP chip
According to pattern project or radiation source 3 and optical clear component 2 between transparent LED display, LED display are set
It has imported slice of data and has shown the negative needle drawing case (showing the blank parts in slice pattern) of slice of data, radiated
If source 3 is ray machine, the illumination of ray machine crosses partial obscuration by the way that LED display is laggard, can project slice pattern,
In in order to meet the light that radiation source 3 can radiate a variety of different wave lengths, radiation source 3 is the combination of multiple light sources, each light source point
The light of different wave length can not be issued, specific radiation is that can be ultraviolet light, visible light or infrared ray laser, preferably
Ultraviolet light.
Step 102, polymerizable liquid 4 is configured, then fills polymerizable liquid 4 to consolidation zone, wherein polymerizable liquid
Include multiple components in body 4, includes monomer and/or prepolymer and different photoinitiators in each component, different light draws
Hair agent enables to monomer and/or prepolymer that polymerization reaction respectively occurs after the radiation energy for receiving different wave length；
Print procedure
Step 103, radiation source 3 provides radiation energy, each radiation scope 7 and every layer of slice map to three-dimensional fabrication region
Case is corresponding, and polymerization reaction is occurred by the polymerizable liquid 4 that radiates, and is formed on the surface of carrier 1 certain thickness solid
The 3D printing part 5 of change, then carrier 1 drives 3D printing part 5 far from Stereolithography face 6, and 3D printing part 5 is made to have new growth
Space, wherein the thickness for the 3D printing part 5 that the radiation of constant range is formed every time is related with radiated time, when the time of radiation
Between it is longer, i.e., cured 3D printing part 5 is thicker；
Step 104, step 103 is repeated, so that the successively solidification accumulation molding of polymerizable liquid 4,3D printing part 5 meet expection
Printing can be completed in printing；
Printing post-processing
Step 105, the 3D printing part 5 of completion is post-processed, general post-processing includes the next steps: (1) cleaned
The defective material on 5 surface of 3D printing part, (2) remove the additional structure being used to support in print procedure on 3D printing part 5, and (3) carry out
The rear curing process of heating, supplement radiation, (4) further polish to the surface of 3D printing part 5.
In above-mentioned photocuring 3D printing step, the polymerizable liquid 4 of multiple components is configured in step 102, wherein each
The photoinitiator for including in component is to realize that different components receive the principal element that polymerization reaction occurs after different wave length radiates, example

350-400nm absorbs cause 420nm or so always；The absorption wave of 2- hydroxy-methyl phenyl-propane -1- ketone (photoinitiator -1173)
A length of 244nm, 278nm, 322nm；The absorbing wavelength of photoinitiator -4265 is 239nm, 275nm, 379nm；2,4,6- trimethyl
The absorbing wavelength of benzoylphenyl phosphinic acid ethyl ester (photoinitiator-TPO-L) is 273nm, 370nm；Isopropyl thioxanthone (2,
The mixing of 4 isomeries；Photoinitiator -1105) absorbing wavelength be 258nm, 382nm, the photoinitiator for visible light is since it makes
With condition and keep condition harsher, so the photoinitiator for visible light designed on the market is less, it is actually double
2,6- bis- fluoro- 3- pyrroles's phenyl titanocenes, benzil ketals substance, thia mattress letones may be implemented, but general
Aided initiating is added, enough can buy UV-LED visible light photo initiators JDADE 276 (by Qingdao Jie get Jia new material on the market
Science and Technology Ltd.'s sale) maximum absorbable wavelength is 430nm and bis- [2,6- bis- fluoro- 3- (1H- pyrrole radicals -1) phenyl]
The absorbing wavelength of titanium cyclopentadienyl (visible light photo initiators 784) is 400-480nm (being sold by Changshu Heng Rong commerce and trade Co., Ltd), therefore this
What radiation source described in invention issued can be the different wave lengths such as ultraviolet light, visible light or infrared ray laser as polymerizable
What the energy transmission that polymerization reaction occurs for different component in liquid 4 can be achieved on.
And it is free radical polymerizable material or epoxy group that monomer in polymerizable liquid 4 and/or prepolymer, which can be,
Polymerizable material, specifically, the functional group of free radical polymerizable material includes methacrylate, alpha-olefin, N- vinyl, third
Acrylamide, Methacrylamide, phenylethylene, epoxides, mercaptan, 1,3- diene, vinyl halide, acrylonitrile, ethylene
Base ester, maleimide, vinyl ethers or the derivative of above-mentioned one or more functional groups；The official of epoxy group polymerizable material
It can roll into a ball including oxirane ring, propylene oxide ring, 7-oxa-bicyclo[4.1.0 base or the derivative of above-mentioned one or more functional groups, it is right
In the type and proportion of the type and specific proportion and photoinitiator of monomer and/or prepolymer, present embodiment not
It is limited.
In 4 solidification process of polymerizable liquid, polymerization reaction occurs for the radiation that different components can absorb different wave length, Gu
Chemical conversion type collectively constitutes 3D printing part, since the radiation source range for providing polymerizing energy is wider, therefore corresponding polymerizable liquid
Component selectivity it is wider, the performance after material solidification is more diversified, and due to use multi radiation sources, each radiation source
Institute reduces for energy, i.e., low to the energy requirement of single source in 3D printing, so the manufacturing cost of equipment is reduced, and
