Description

technical field

[0001] The invention belongs to the technical field of additive manufacturing, and in particular relates to a slurry lamination automatic supply device and a control method within a variable area range. Background technique

[0002] Traditional ceramic molding methods, including dry molding, plastic molding and slip casting, all require molds to prepare ceramic products with specific shapes. Due to its inherent shortcomings such as long cycle time and high cost, traditional ceramic molding methods are becoming more and more difficult to meet the growing market demand. At the same time, with the development of additive manufacturing, more and more materials can be used for additive manufacturing. Among them, the additive manufacturing technology of ceramics has also begun to become a frontier topic in the preparation of ceramic materials.

[0003] In terms of high-precision ceramic additive manufacturing technology, it is mainly laser selective sintering (SL...
