In some embodiments, on the nozzle component at least provided with the first feed(raw material)inlet, the second feed(raw material)inlet and
Third feed(raw material)inlet can also have multiple entrances for printing multi-component material；First feed(raw material)inlet and the second raw material enter
Mouth is connect by the volume pump with the printed material nozzle；The third feed(raw material)inlet passes through volume pump and the fid
Expect nozzle connection, the volume pump that wherein backing material nozzle is connected with printed material nozzle is independent.If printed material is single
The fluent material of component, then can select the first feed(raw material)inlet or the second feed(raw material)inlet by feedstock transportation to printed material nozzle
It in connected volume pump, is conveyed by volume pump-metered, and is squeezed out from printed material nozzle and complete printing.When each layer of part is real
After body printing finishes, backing material is transported in the volume pump being connected with backing material nozzle by third feed(raw material)inlet, by
It, which measures and passes through backing material nozzle, squeezes out the printing for completing backing material.
The shorter nozzle in the present invention in nozzle component the better with a distance from pump head, is conducive to the stream for controlling printed material
Amount, all arranged farther out with other schemes in the market, compared using modes such as long-range delivery pipes, can to avoid pressure it is high after
Delivery pipe deformation leads to problems such as to measure inaccuracy.And control of the control system to nozzle component, it is different in nozzle path
Position can have different amount of liquid, different liquid mixing ratios, thus realize functionally gradient material (FGM) print.
In some embodiments, the nozzle diameter of the spray head is 0.05~3mm；Preferably, the nozzle of the spray head
Diameter is 0.05~0.8mm.
The backing material of heretofore described backing material nozzle extrusion molding can select PLA, ABS, PVA, PVP etc..
These materials are drawn into silk, squeeze out after being heated to its melting temperature, instantaneous solidification, thus to soft liquid extrusion molding knot
It is configured to effectively support.Preferably, the backing material uses water-soluble high-molecular material, such as PVA, PVP etc. has printed
It impregnates removal support in water later, leaves workpiece.And since printed material is different from the printing type of backing material, if real
Now printing backing material then needs backing material nozzle.
In some embodiments, the printing device contains at least one support nozzle component, can print complexity
Space structure do not collapse, the support is by water-soluble or be easy to impregnate removing by solution or pass through heating
The material of removing is made, and can simply and easily be removed after printing, even if in the backing material of inside parts, it can also be with
It is removed in the case where not damaging printout.
Heretofore described backing material also can be used after the fluent material similar with material of main part squeezes out solidification and be formed
Support, but this fluent material must be water-soluble, or pass through the lossless removals of means such as heating.
In order to enable thermoplastic macromolecule material in nozzle component can proper flow, and smoothly squeeze out, in some realities
It applies in mode, is provided with heating device on the backing material nozzle.Particular determination is not done to the heating device, can be sleeve
Electric heater unit etc..
It is being controlled by the plunger pump being connected in parallel so that each pump can be controlled separately the printing raw material that conveying comes
In system processed under the control of G code, the extrusion accounting of each component can be adjusted in real time, and printing shaping obtains different location tool
There is the functionally gradient material (FGM) of different performance.
In some embodiments, control of the volume pump motor by central control board card, and and movement executing mechanism
Control it is mutually coordinated.
The second aspect of the invention provides a kind of space combining properties 3D printing equipment based on liquid instantaneous solidification
And method, utilize 3D printing equipment as described above.
For being liquid under the material room temperature of 3D printing in the present invention, and can be real under light, electricity, heat, catalyst
Existing second grade solidification.Particular determination is not done to above-mentioned material, bis- (more) mixing cured glue materials of component can be selected；Heat cure, light
Solidify glue material；Catalyst (oxidation, moisture) solidification glue material etc., including but not limited to Multi-component Polyurethane, multicomponent epoxy
Resin, multicomponent silica gel etc..
Since the liquid material printed cannot support own wt, so if it mixes later curing rate too
Slowly, then it is easy to make itself deform before uncured molding and printing is failed.So needing is that the material printed has
Shorter curing time is able to achieve second grade solidification.In some embodiments, after the liquid material of printing squeezes out, solidification
And stop time≤120s of flowing, reach 30% time that intensity is fully cured, is lower than 300s.
In some embodiments, the flow of printing fluid material is 0.01~100cm3/ min, flow control accuracy: ±
(1%-5%).By using specific volume pump or combined volume pump, control the flow of printed material accurately
System facilitates printing and obtains fine structure, stable 3D moulding material.
In some embodiments, the range of viscosities of printing fluid material is 200000-3000000 CPS.
It is thin from the formation after printed material nozzle extrusion to significantly affect printed material for the viscosity of printed material in the present invention
Pressure etc. in the shape of stream, printed material nozzle, will have a direct impact on whether print procedure goes on smoothly.If printed material is glutinous
Du Taigao is easy to form higher pressure in printed material nozzle interior, occurs material after printed material nozzle extrusion empty
Mouth swells phenomenon, causes thread uneven or the rupture of liquid, not easily molded.And if the viscosity of printing material is too low, it is easy
Cause the product structure of printing shaping it is not fine enough, can not accumulation molding, influence quality.So heretofore described printing fluid
The viscosity of material controls within the scope of 200000-3000000CPS.
In some embodiments, the volume pump can squeeze out pigment, and RGB tri- is arranged using three volume pumps in parallel
The raw material of primary colors is implemented to squeeze out after being mixed it with different component proportions, then mixes with material and colour print can be realized.
The present invention is specifically described below by embodiment.It is necessarily pointed out that following embodiment is only used
In the invention will be further described, it cannot understand that s is limiting the scope of the invention, professional and technical personnel in the field
The some nonessential modifications and adaptations made according to the content of aforementioned present invention, still fall within protection scope of the present invention.
