Silicon carbide (SiC) ceramics have excellent properties such as high temperature resistance, good oxidation resistance, high thermal conductivity and low thermal expansion coefficient, so they are widely used in the production of heat exchangers, high thermal conductivity large-scale integrated circuit substrates, rocket nozzles and other products.

However, the high hardness and brittleness of SiC ceramics make it difficult to process. Traditional SiC ceramic forming technologies include dry pressing, isostatic pressing, slip casting, injection molding, etc. Molds are required in the process of preparing SiC ceramic green bodies. The entire production cycle is time-consuming and costly, and it is difficult to manufacture relatively complex parts and composite structures.

Therefore, industrial production urgently needs a forming method for high-performance complex-shaped ceramic parts. This time, let's take a look at the case of our company using self-developed desktop DLP light-curing 3D printing device to print a fine G-type surface  structure of silicon carbide parts.
