Scraper leveling device and method for manufacturing three-dimensional object

Abstract

The invention discloses a scraper leveling device and method for manufacturing a three-dimensional object. The scraper leveling device comprises two or more distance sensors and a display unit used for displaying detection data of the distance sensors. The two or more distance sensors are arranged on a scraper fixing mechanism and located at the same horizontal position, and accordingly a forming base plate and a scraper are leveled according to the data displayed by the display unit and detected by the distance sensors. According to the scraper leveling device and method for manufacturing the three-dimensional object, equipment damage caused by adjustment through a feeler gauge is avoided. Meanwhile, detection is conducted through the distance sensors, accordingly, by means of the scraper leveling device and method for manufacturing the three-dimensional object, the scraper leveling accuracy is higher, and operation is simpler and more standard.

Description

technical field [0001] The invention belongs to the field of additive manufacturing, and in particular relates to a scraper leveling device and a leveling method for manufacturing three-dimensional objects. Background technique [0002] Additive Manufacturing technology (Additive Manufacturing, referred to as AM) is an advanced manufacturing technology with distinctive features such as digital manufacturing, high flexibility and adaptability, direct CAD model drive, fast speed, and rich and diverse material types. Since the late 1980s So far, it has become a pillar technology in modern advanced manufacturing technology. Selective Laser Melting (SLM for short) is one of the additive manufacturing technologies that has developed rapidly in recent years. It uses powder materials as raw materials and uses lasers to scan the cross-section of a three-dimensional entity layer by layer to complete prototype manufacturing. It is not affected by the complex shape of parts. The degree...

Problems solved by technology

In the existing scraper leveling process, the scraper is first installed on the scraper seat through the pressure plate, and the distance between the bottom surface of the scraper and the forming substrate is roughly adjusted through the hooks at both ends of the scraper seat; on the premise that the rough adjustment is completed, the scraper is judged by a feeler gauge Whether the distance between the bottom s...
