Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing, in particular to an auxiliary scraper device for 3D printing models. Background Art

[0002] 3D printing is a kind of rapid prototyping technology, also known as additive manufacturing. It is a technology that uses digital model files as the basis and uses powdered metal or plastic and other bondable materials to construct objects by printing layer by layer. In the 3D printing process, it is necessary to apply photosensitive resin or photosensitive ceramic slurry and other liquids layer by layer. When the viscosity of the liquid is high, due to poor fluidity, defects such as faults, incomplete coating or uneven thickness are prone to occur. In order to avoid the occurrence of the above defects, a scraper mechanism is usually used to coat each layer to ensure the continuity, integrity and thickness uniformity of the coating. In the process of 3D printing, especially in the process of metal printing, the scraper wears faster and needs to be replaced frequently. The existing scrapers are fixed by bolts. When replacing, the scraper assembly needs to be removed and then replaced, which takes a lot of time. Therefore, an auxiliary scraper device for 3D printing models is proposed to solve the above problems. Utility Model Content
