Embodiment in the present invention, those of ordinary skill in the art are obtained all without making creative work
Other embodiment belongs to the range that the present invention is protected.
The one kind that is designed to provide of present embodiment is exempted to support photosensitive 3D printer, solves 3D in the prior art and beats
The support portion addition difficulty of print is larger, directly affects the problem of molding of printing effect and support portion causes waste of material.
Hereinafter, being illustrated referring to attached drawing to embodiment.In addition, embodiments illustrated below is not to recorded in claim
Summary of the invention rise any restriction effect.In addition, the full content of composition represented by following example is not limited to as right
Necessary to the solution invented documented by it is required that.
Please refer to Fig. 1 and Fig. 2, in the present embodiment, exempt to support photosensitive 3D printer include platform assembly, raw material box 4 with
And volatile dry device 5 and light-source system 6.Platform assembly includes that horizontally disposed first platform 1, barrel pipe 3 and setting are being expected
The second platform 2 in bobbin 3, the first platform 1 are equipped with embedding mouth, and the upper end of barrel pipe 3 is in embedding mouth, and the first platform 1
Upper surface and barrel pipe 3 upper end flush, the inner wall at the edge and barrel pipe 3 of the second platform 2 is in sealing contact, and second
Platform 2 can move along the vertical direction in barrel pipe 3, and the upper surface of the inner wall of barrel pipe 3 and the second platform 2 surrounds raw material tank
10.Light-sensitive material is held in raw material box 4, the lower end of raw material box 4 is equipped with opening 9, and be open 9 edge and the upper table of the first platform 1
Face is in sealing contact, and raw material box 4 can be mobile relative to the first platform 1, and shift position includes positioned at the top of the second platform 2
First position and the second position on the first platform 1, it is photosensitive in raw material box 4 when raw material box 4 is moved to first position
Material is flow in raw material tank 10 by opening 9, and when raw material box 4 is moved to the second position, the opening 9 of raw material box 4 is by the first platform 1
It blocks.Volatile dry device 5 and light-source system 6 are arranged at the top of the second platform 2, and volatile dry device 5 is for accelerating original
The volatilization of solvent in hopper 10 in light-sensitive material, light-source system 6 are used to project ultraviolet light image to light-sensitive material.
When carrying out 3D printing, light-sensitive material is added into raw material box 4, the position of the second platform 2 of adjustment is moved up and down, makes
Have the difference in height of a thickness between the second platform 2 and plane where the first platform 1, raw material box 4 is in first position and the
It is moved back and forth between two positions, adds light-sensitive material into raw material tank 10 when raw material box 4 is moved to first position, when raw material tank 10
When interior liquid level is concordant with the upper surface of the first platform 1, raw material box 4 is moved to the second position, and volatile dry device 5 accelerates
The solvent of light-sensitive material in raw material tank 10 volatilizees, i.e., the volatilization of organic solvent or water in quickening light-sensitive material, so that photosensitive
Material forms the uniform film layer of semisolid by way of heating, drying, and the solvent or water in the light-sensitive material are being evaporated completely completely
Bi Hou, in the state being completely dried, film layer when in half-dried or completely dried state all has certain degree of hardness and support
Power, the film layer can be used as the support portion of model and provide support for subsequent uv-exposure process, then by light-source system 6 to partly
The uniform film layer of solid projects ultraviolet light image, so that photocuring reaction, consolidating after being crosslinked occur for the exposure position in film layer
Body, the above printing for just completing a thickness；The second platform 2 moves down the distance of a thickness later, and raw material box 4 is mobile
To first position, light-sensitive material is filled into raw material tank 10, continues the printing of next thickness, until printing is completed.
It should be noted that the uniform film layer of semisolid is the thermoplastic material of linear structure, viscosity is reduced or is melted after being heated
Change, organic solvent or water can also be dissolved in.It is the netted thermosetting property of macromolecular by the linked solid obtained after uv-exposure
Material, heating will not melt, and be insoluble in solvent or water.It therefore, can will be without uv-exposure after the completion of printing
The uniform film layer of semisolid is dissolved with solvent, it can also be accelerated to be dissolved in solvent by heating and softening reduction viscosity, obtained
Required 3D printing model, the semisolid film layer dissolved can also utilize again, not generate the waste of material.
So set, volatile dry device 5 and light-source system 6 match, the drying functions of volatile dry device 5 make light
Quick material becomes the uniform film layer of soluble semisolid, and the part that light-source system 6 exposes obtains not having deliquescent model, In
During uv-exposure, the uniform film layer of semisolid is played a supporting role, and the addition of additional support portion is avoided, and improves printing
Success rate, and can be reused after semisolid uniform film layer dissolution, avoid the waste of material.
In addition, the inner wall at the edge and barrel pipe 3 of the second platform 2 is in sealing contact, it can effectively avoid light-sensitive material from
It is flowed out between two platforms 2 and barrel pipe 3, causes the waste of material.The upper end of barrel pipe 3 is concordant with the upper surface of the first platform 1,
Raw material box 4 is steadily moved on the first platform 1, in case the light-sensitive material in raw material box 4 largely flows to the first platform 1
On.The upper surface of the opening 9 of raw material box 4 and the first platform 1 avoids the material in raw material box 4 from flowing to first by pressure contact
On platform 1.In the present embodiment, the filling speed of light-sensitive material depends between raw material box 4 and the first platform 1 in raw material tank 10
Relative moving speed, guarantee light-sensitive material by enough time for exposure under the premise of, increase raw material box 4 movement speed,
Printing effect can be improved.
Specifically, for the light-sensitive material of 3D printing, the principal resinous ingredients in light-sensitive material can be acrylate
Oligomer, acrylic acid groups can participate in photochemical reaction, which can be stable in the presence of water under the action of emulsifier
Or it is directly dissolved in other organic solvents.By taking water as an example, when not having ultraviolet lighting, which has water-soluble
Property, water dissolution is met, ultraviolet lighting is mapped on initiator, will crack out free radical, generates free radicals reaction, and it is double to cause acrylic acid
Key polymerization, forms reticular structure and the huge polymer of molecular weight after polymerization, no longer have water-soluble, constitutes in this programme
Model, and after not volatilized by the oligomer of ultraviolet lighting due to water, do not have mobility, the softening point of oligomer itself is higher
It (being usually above room temperature), so that its own is in semi-solid state, plays a supportive role as support portion.
In the preferred embodiment of the present embodiment, volatile dry device 5 includes blower 51 and heating device, the outlet air of blower 51
Mouth is oppositely arranged with the second platform 2.So set, the air that heating device blows out blower 51 heats, so that blower 51 is to the
Two platforms, 2 blowing hot-air accelerates the solvent volatilization in the light-sensitive material in raw material tank 10.So set, 5 pairs of light of volatile dry device
Quick material drying, obtains soluble semisolid film layer, realizes the self support during 3D printing.
Specifically, heating device is infrared lamp 52.Infrared lamp 52 transmits infrared emanation on the second platform 2.Certainly, In
In other embodiments, heating device can also be the heating wire being arranged on 51 air outlet of blower, by heating wire to blower 51
The wind of blowout heats, to achieve the purpose that dry light-sensitive material.
