Mineral powder material increase manufacturing process and device

Abstract

The invention provides a mineral powder material increase manufacturing process and device. The manufacturing process includes the following steps that a solid three-dimensional model needing to be subjected to material increase manufacturing is established, and the model is sliced; mineral powder is spread according to powder spreading trajectories, and meanwhile a binding agent and a catalyst are added into the mineral powder so that the mineral powder, the binding agent and the catalyst can be mixed with one another in the falling process and be spread on a manufacturing platform along the powder spreading trajectories; and layer-by-layer stacking is performed according to the powder spreading trajectory of each layer of slices, and thus material increase manufacturing solid forming can be completed. The invention further provides the manufacturing device correspondingly. The manufacturing device comprises a base, the manufacturing platform, an XYZ three-axis moving mechanism and a material spraying system. According to the mineral powder material increase manufacturing process and device, the mineral powder is used for performing material increase manufacturing, so that manufacturing cost is reduced; and a traditional powder material increase manufacturing method is improved, manufacturing efficiency is improved, entity manufacturing aftertreatment difficulty is lowered, and accordingly a large-sized geological and geomorphologic model, a three-dimensional topographic map, an artificial landscape model and the like can be manufactured.

Description

technical field [0001] The invention relates to an additive manufacturing process and a manufacturing device, belonging to the technical field of additive manufacturing. Background technique [0002] Additive manufacturing refers to the process of manufacturing a digital model into a three-dimensional entity by adding materials layer by layer. The existing additive manufacturing devices mainly use metal powder, molten plastic, and ceramic slurry. These devices and preparation processes have the problems of high manufacturing cost, slow solidification and molding speed, and cannot be used for large-volume physical manufacturing. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a process and device for additive manufacturing using mineral powder. [0004] The technical solution adopted to achieve the object of the present invention is a mineral powder additive manufacturing process, comprisi...
