Technical Field
The utility model relates to a 3D prints technical field, especially relates to a powder device and 3D printer are pressed to powder is spread to 3D printer.
Background
The SLM3D printer is one of additive manufacturing equipment, is directly printed with metal powder, and the part mechanical properties that it printed are good, and the metal compactness is high, and this printer utilizes laser to act on metal powder and makes it melt, and the cooling is piled up and is formed, connects closely between the layer, and its compactness can reach more than 90%. The method is widely applied to the fields of spaceflight and medical treatment. The density of the printed part is influenced by the powder spreading mechanism of the SLM3D printer on one hand. The uniformity of the spread powder is affected by the scraper bar. The height difference and the stress condition between the scraping strip and the substrate. At present, a powder spreading scraper with a common silica gel strip as a scraping strip properly extrudes a substrate before printing to realize the uneven stress of the defects existing in the powder pressing and spreading in the printing process, and the scraper has no upward lifting and avoiding function.
At present, a powder spreading scraper adopts a roller, silica gel and silica gel strips to scrape powder and spread the powder, the roller is in rigid contact with a substrate, the stress is uneven, the powder spreading is uneven, and the scraper in the form of the silica gel strip scraping strips loses the downward pressure due to the fact that the surface of the scraper is abraded and the contact surface of a powder bed is irregular after long-term printing. Powder device is spread to common 3D printer structure is complicated, scrapes the strip and damages and can not carry out the under-deck change, and its two, common scraper motion adopts single scraper to scrape the powder, and the scraper atress is inhomogeneous, leads to spreading powder density inconsistent. The scraper does not have a lifting avoiding device, and when the surface of a part is warped or protruded, the part can be impacted by the back-and-forth movement of the scraper, so that the printing failure is caused.
