The ceramic part base substrate that step 2 is obtained first is carried out into impregnation process；
Then the ceramic part base substrate again to impregnation process carries out pre-sintering, and temperature is raised to 200 by pre-sintering from room temperature 2h
DEG C and be incubated 1h, then 2h is warmed up to 400 DEG C again, is finally warmed up to 450 DEG C by 1h and is incubated 2h；In pre-sintered process simultaneously
Also degreasing is completed, that is, eliminates the binding agent inside ceramic part base substrate；Then again by double sintering, double sintering is by 5h liters
To 800 DEG C~1000 DEG C；
Due to still suffering from residual clearance, stomata in the ceramic part after double sintering is processed, therefore pass through high temperature again
Sintering, high temperature sintering was warmed up to 900 DEG C of insulation 1h through 3 hours；Again 1200 DEG C of insulation 2h are warmed up to by 2h；Heated up by 1h again
To 1400 DEG C insulation 10h, it is to be cooled to room temperature when come out of the stove, with gradually remove in ceramic part remain space, stomata so that pottery
Porcelain part becomes fine and close by loose, until reaching the ceramic part of required consistency and intensity.
The ratio that binding agent solid powder is mixed into described in above-mentioned steps one is 10%~15%.
Binding agent solid powder described in above-mentioned steps one is inorganic binder, organic binder bond or metal adhesive；Step
Binder Composition is identical with binding agent solid powder described in rapid two.
Part blanks 3D printing step is specific as follows described in above-mentioned steps one：
Step A：After completing a powdering, two shower nozzles of 3D printer are controlled to spray binding agent according to the path of regulation
On ceramics layer surface, solidify ceramic powders, to form one layer of solidification ceramics layer；Then, moulding cylinder rises this and consolidates
After changing ceramics layer a quarter thickness, powder-laying roller is moved from right to left, and smooth, compacting is carried out with to solidification ceramics layer surface
Treatment；

Step C：Then, after moulding cylinder declines a quarter thickness of solidification ceramics layer described in step B, powder-laying roller is from a left side
Move right, in the process, the hopper equipped with ceramic powders synchronously carries out powder feeding, powder-laying roller while doing horizontal powdering motion,
While around own axis, ceramic powders to be laid in the surface of the solidification ceramics layer, and it is compacted, it is unnecessary during this
Ceramic powders then enter Powder Recovery box；
Step D：Repeat step A to step C, until 3D printer process finishing, and form the ceramic part of molding bonded
Blank.
Superposition shaping is successively bonded described in above-mentioned steps two, detailed process is：
Outline of one of shower nozzle first to ceramic part in this layer carries out spraying bonding；
The Internal periphery to ceramic part in this layer carries out spraying bonding again；
The powder in region carries out bonding filling between last outline and Internal periphery by another shower nozzle to this layer.
It is to carry out up time along part section contour direction when the shower nozzle carries out spraying bonding to the inside and outside contour of this layer
Pin is counterclockwise moved；Can also be unidirectionally continuously advanced along part section profile.
It is 8um~55um to solidify ceramic powder Layer thickness described in above-mentioned steps C.
The composition of ceramic powders described in above-mentioned steps one is Al2O3Or SiC, ceramic powders particle diameter is 20 μm~50 μm.
There is the different nozzle of multiple diameters, size distribution is 0.1mm-1mm, and the size of nozzle diameter is determined on shower nozzle
The size of binder amount is sprayed, the size of thickness is bonded so as to determine.
Ceramic powders are thinner, and finished product density is higher.A certain proportion of binding agent solid powder is mixed into ceramic powders, can
Make it that chemical reaction occur so as to obtain more preferable compact tissue in pre-sintered state and ceramic powders.
The composition of the binding agent for bonding ceramic powders is not fixed, can be changed according to ceramic powders difference,
The composition of liquid-containing binder and binding agent solid powder can also be inconsistent.Mainly there are inorganic binder, organic binder bond and gold
Category binding agent, early stage can be realized bonding and favourable chemical reaction occurs in pre-sintered state and ceramic powders, and the later stage can be taken off
Fat is removed.
The purpose of infiltration is first to penetrate into colloidal sol to increase ceramic particle before organic adhesive contained in removing part
Between active force, prevent defeated and dispersed.
Pre-sintered purpose has two, one be further make binding agent solidify or it is favourable with ceramic particle reaction generation into
Point, make between binding agent and ceramic powder particle bond more firmly, increase part intensity, two be so that ceramic particle it
Between contact it is even closer, while diffusional resistance when can reduce sintering processes below.
Also the degreasing of part is completed while pre-sintered.And the process of degreasing is to remove remaining binding agent.Skimming processes
Selection should be according to the species of binding agent, depending on ceramic powders and design of part.
The purpose of high temperature sintering treatment is the stomata for eliminating inside parts residual, part is become fine and close by loose, ceramics
Interparticle bond strength increases, and part machinery intensity is improved.It is related to viscous flow, the surface of ceramic particle in sintering process
Diffusion, crystal boundary or lattice diffusion, and plastic deformation.
Sintering processes it is several during, can be carried out by the way of gradually elevated temperature, certain sintering temperature can root
It is configured according to the sintering temperature curve of different ceramic materials.Sintering processes can cause that ceramic part volume contraction, size reduce,
This defect can be by before molding bonded, carrying out dimension compensation to improve to part.
Be combined for molding bonded and sintering process by the present invention, eliminates the substantial amounts of stomata of inside parts, makes part by dredging
Pine becomes fine and close, obtains the part of required consistency and high intensity.The part strength for overcoming existing process processing is relatively low, can only
Do conceptual model, and can not do work can property ceramic part technological deficiency.
It is high during multiple gradual intensification sintering processes due to being point contact between the ceramic powders after molding bonded
The effect of temperature causes the expansion of the interparticle contact area of ceramic powders, particle aggregation, volume contraction.With granular center distance
Approach, gradually form crystal boundary, stomata is gradually compressed in this course, and volume diminishes, from connection stomata gradually become

Specific embodiment
Below in conjunction with the accompanying drawings 1 to 9 and specific embodiment, the present invention is more specifically described in detail.
As shown in figure 1, the technological process early stage is molding bonded, by the method using jet binder by forming room
Ceramic powders molding bonded, obtain the ceramic part base substrate of structure with complex shape.Then have to ensure part blanks
There are certain intensity and holding structure integrality, before ungrease treatment, after the powder particle of removing part blank remained on surface again
Carry out pre-sintering.
As shown in Fig. 2 ceramic powders filter out the powder particle that particle diameter is 20~50 μm by prefabricated, certain ratio is mixed into
The binding agent solid powder of example (10%~15%), is put into the moulding cylinder in shaping chamber.Two shower nozzles 4,5 of control are according to rule
Binding agent is injected in bisque surface by fixed path, solidifies ceramic mixed-powder, and bonding thickness is that T2 (solidifies ceramics
Bisque), moulding cylinder rises slightly, and then powder-laying roller 7 is moved from right to left, in the process, 7 pairs of solidification ceramics layers of powder-laying roller
Surface carries out smooth, pressing treatment, removes the part of thickness (i.e. stratum disjunction) T3, and resulting actual thickness is T2, sees Fig. 3.
The part got rid of enters garbage collection box 1, and then moulding cylinder declines an actual thickness, and powder-laying roller 7 is moved from left to right,
During this, hopper 8 carries out powder feeding, and the one side of powder-laying roller 7 moves horizontally, while around own axis, ceramic powders are spread
Put down and be compacted.Unnecessary ceramic powders enter Powder Recovery box 9.Said process is constantly repeated, and is bonded until process finishing is formed
The ceramic part base substrate 6 of shaping.
Shown by Fig. 4 be the place layer of ceramic part base substrate 6 design drawing cross sectional shape, section have inside and outside contour surround in
Between entity part constitute.Because section may be irregular shape, using shower nozzle jet binder molding bonded, shower nozzle is driven
The necessary repeatedly starting and stopping of stepper motor of X, Y-direction motion is carried out, motor may so be caused damage, shower nozzle is constantly added and subtracted
Speed, the control to spray technology also brings inconvenience.So shower nozzle is using unidirectional motion control.
As shown in figure 5, in theory, in the presence of dropping in surface tension due to the binder liquid for ejecting, with pottery
Porcelain powder acts on two ends and can form the bonding road of circular arc so that bond the concavo-convex fluctuating of piece surface.Simultaneously because bonding
The constraint of agent drop own form so that actual shaping outline is bigger than design profile, actual shaping Internal periphery compares design profile
It is small, and there is obvious form error in actual profile.With the increase of the processing number of plies, this profile errors and shape
Shape error gradually increases so that the surface quality of workpieces of molding bonded is deteriorated, and roughness is very big.
In order to improve this bad situation, a kind of new paths planning method is designed:As shown in fig. 6, by design drawing
The inside and outside contour in section carries out inside and outside skew, offsets formed ring part and is transported according to along annular direction using shower nozzle
Dynamic jet binder, the surfaces externally and internally of such profile can realize that smooth no concave-convex rises and falls, such as Fig. 7.
In order that interlaminar bonding is preferably combined, alternately moved along X, Y direction by setting shower nozzle 4, realized in interlayer
Road is bonded orthogonal, as shown in figure 8, the movement locus of shower nozzle 4 is：N-th layer is sprayed along the Y direction, and the screw mandrel of X-direction exists
Feed motion is carried out in horizontal direction, N+1 layers is sprayed along the X direction, the screw mandrel in the vertical direction of Y direction is carried out
Feed motion.It is achieved in that interlaminar bonding region is orthogonal, greatly strengthen the intensity of part molding bonded.
Because, for point is contacted, during sintering processes, the effect of high temperature is caused between the ceramic powders after molding bonded
The expansion of interparticle contact area, particle aggregation, volume contraction.With approaching for granular center distance, crystal boundary is gradually formed,
Stomata is gradually compressed during this, and volume diminishes, and isolated stomata is gradually become from the stomata of connection, so that exclude, most
Turn into DB eventually.
Fig. 9 illustrates ceramic powder particle aggregation in sintering process, and volume-diminished excludes stomata, eventually forms non-porous many
The process of crystal.A procedural representations is grain rearrangement in figure, and granular center is close to during b1 represents the particle system of fluff packing.
B2 represented in closelypacked system, and granular center is close to.Closelypacked powder easily forms finer and close part.
As described above, the present invention can be better realized.
Embodiments of the present invention are simultaneously not restricted to the described embodiments, and other are any without departing from Spirit Essence of the invention
With the change, modification, replacement made under principle, combine, simplify, should be equivalent substitute mode, be included in of the invention
Within protection domain.
