Abstract

The invention discloses a slurry lamination automatic supply device with variable area range and a control method. The slurry lamination automatic supply device comprises a feeding spray head, a scraper, a material storage cylinder, a pressurized air pump, a scraper cleaning device, a waste material collecting cylinder, a forming cylinder, a printing platform, a feeding spray head driving motor, afeeding spray head support frame, a spiral propeller, a mounting back plate, a first X-axis moving platform, a second X-axis moving platform and a Y-axis moving platform. According to the slurry lamination automatic supply device, a feeding mode of the scraper matching with the feeding spray head is adopted, the purposes of variable auxiliary material area and controllable range are achieved, when parts with small area are formed, the moving distance of the second X-axis moving platform can be controlled to select the slurry laying area, and thus the beneficial effect of saving slurry is achieved.

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...

Problems solved by technology

However, if the content of ceramic powder is too high, the slurry will be viscous, and the uniformity of slurry coating and printing quality cannot be guaranteed.

At present, some light-curing molding technologies use a combination of a storage tank and a scraper to supply the slurry. However, due to the single and fixed feeding method of this slurry supply method, each layer of slurry needs to be evenly spread on the entire printing surface. On the platform, a large amount of ceramic slurry is required even when molding small-volume ceramic parts

In addition, the above-mentioned slurry supply method still has the problem of slurry sticking to the scraper when covering ceramic slurry with high solid content and high viscosity, resulting in uneven slurry coating
