Embodiment 1

[0030] This example discloses a method for strengthening treatment of ceramics based on 3D printing. As a basic embodiment of the present invention, it includes degreasing the formed green body after ceramic 3D printing to obtain a degreased green body; The degreased green body is sintered to obtain a ceramic body; finally, the ceramic body is strengthened. Among them, the formed green body, the degreased green body and the ceramic body all include a body part and a body support part, and the specific steps for strengthening the ceramic body are as follows:

[0031]Step 1, put the ceramic body into the container equipment equipped with strengthening liquid I, and vacuumize the inside of the container equipment to 0.05~0.08MP, so that the ceramic body is soaked in the strengthening liquid I for 10~40min;

[0032] Step 2, release the internal pressure of the container equipment to normal pressure, and then soak the ceramic body in the strengthening liquid Ⅰ for 20-60 minutes;

...

Embodiment 2

[0037] This example discloses a ceramic strengthening treatment method based on 3D printing. As a preferred embodiment of the present invention, specifically, the molded body is sequentially subjected to degreasing treatment, sintering treatment and ceramic body strengthening treatment, wherein the degreasing treatment Including the preliminary strengthening of the green body and the degreasing of the green body, the specific steps are as follows:

[0038] Preliminary strengthening of the green body:

[0039] Step 1: Put the formed green body into a container equipped with strengthening liquid Ⅰ, and vacuum the interior of the container to 0.05~0.08MP, so that the formed green body is soaked in the strengthening liquid Ⅰ for 10~40min; wherein, strengthening liquid Ⅰ It is one of silica sol, aluminum sol and ethyl silicate hydrolyzate;

[0040] Step 2: Release the internal pressure of the container equipment to normal pressure, and then soak the formed green body in the streng...

Embodiment 3

[0051] This example discloses a ceramic strengthening treatment method based on 3D printing.

Abstract

The invention belongs to a ceramic strengthening method, and particularly relates to a ceramic strengthening treatment method based on 3D printing. The method comprises the following steps: degreasinga molded green body subjected to ceramic 3D printing to obtain a degreased green body; sintering the degreased green body to obtain a ceramic body, and finally strengthening the ceramic body. The degreasing treatment comprises green body primary strengthening and green body degreasing, and the sintering treatment comprises green body secondary strengthening and green body sintering. According tothe technical scheme, the problems of low strength and large shrinkage of a molded green body of existing ceramic 3D printing after degreasing can be solved, so that the reliability of ceramic post-treatment is improved, and the success rate of a ceramic 3D printing technology is increased, namely, the yield of ceramic 3D printing products is increased; and meanwhile, the strength of the ceramic products is also improved.

Description

technical field [0001] The invention belongs to a ceramic strengthening method, in particular to a 3D printing-based ceramic strengthening treatment method. Background technique [0002] In the environment of 3D printing intelligent manufacturing, because ceramic 3D printing has high efficiency and can form various complex structures that cannot be completed by traditional techniques, it plays an irreplaceable role in the field of precision ceramics. Porcelain 3D printing products are used in aerospace, medical , industrial manufacturing and decorative design and other fields have been well cited, therefore, ceramic 3D printing technology is rising rapidly. In order to adapt to the current development trend of 3D printing, ceramic 3D printing technology based on various principles has developed rapidly, among which SLA is the most representative. However, due to the particularity of ceramic materials, in the process of development of ceramic 3D printing technology, there are...
