Background
The ceramic photocuring forming is a novel forming method which does not depend on a mould and can quickly and efficiently prepare a ceramic device with a fine structure. The forming process of the method is mainly based on photoinitiation for preparation, namely ultraviolet laser irradiates the surface of ceramic slurry with photosensitive characteristic to excite free radical polymerization reaction, so that a solidified layer is formed in a laser scanning area; then the solidified layer descends by a platform height, the uncured slurry is paved above the solidified layer again, laser irradiation and curing are carried out again, then the platform descends again, the paving material … … finally forms a ceramic green body with a certain shape and structure in a layer curing and combining mode, and then the green body is subjected to thermal degreasing, sintering and post-processing to form finished ceramic.
The ceramic green body is obtained by 3D printing of ceramic slurry, and because the ceramic slurry contains more than 20% of organic matters, thermal removal is carried out in a subsequent degreasing link. If the organic content is too high, a polymer network structure is formed by crosslinking in the photocuring process, and stress is generated due to curing shrinkage in the photocuring molding process, which increases the difficulty of degreasing. In order to avoid undesirable phenomena such as cracking, deformation and the like, a common means is to add a plasticizer into the components of the slurry to improve interlayer bonding stress in a printing blank; secondly, the temperature rise of the degreasing is reduced in the degreasing process, even to 10 ℃/h, so that the whole degreasing time can be as long as about 6 days.

Example 2
Taking 20 molded blank sample strips in the embodiment 1, weighing and measuring the size of the sample strips respectively, taking 10 molded blank sample strips, placing the 10 molded blank sample strips in aviation kerosene, and soaking the sample strips for 24 hours at room temperature, wherein the sample strips can be completely immersed by the amount of the aviation kerosene; the molded green body sample after completion of the soaking was placed in a petri dish, and then dried in a drying oven, and the petri dish was covered with a lid to keep the petri dish in a half-open state in order to control the drying speed. Then dried at 50 ℃ for 4h.
The molded green body specimens were again subjected to dimensional measurement and weighing, and the average of the measured data was calculated.
In addition, 10 molded blank sample bars are directly dried for 4 hours at 50 ℃ without being soaked in kerosene.
The test data of the shaped bodies after kerosene soaking and drying are shown in table 1:
TABLE 1 test data (mean) of the shaped green bodies, specimens before and after drying by immersion
| Sample(s) | Long (mm) | Width (mm) | Thickness (mm) | Weight (g) |
| Before soaking | 59.14 | 4.91 | 3.68 | 2.66 |
| After soaking and drying | 57.57 | 4.78 | 3.58 | 2.52 |
As can be seen from Table 1, the molded green body specimens subjected to kerosene immersion and drying treatment were able to undergo preliminary shrinkage and thermal weight loss, which reduced undesirable phenomena such as shrinkage cracking, deformation, etc. caused by direct thermal degreasing of the printed green bodies.
In order to further study the beneficial effects of solvent degreasing on the formed body, the formed body sample strips (10 strips) soaked in kerosene and dried are compared with the sample strips (10 strips) not soaked in kerosene, and the porosity of the formed body sample strips is tested by a Mac Auto Pore 9520 mercury intrusion instrument.
