AI Technical Summary

Technical Problem

The existing powder spreading unit has a fixed distance from the powder spreading plane, which makes it difficult to adapt to different powder particle sizes, changes in flowability, and height errors during the forming process. This results in uneven powder spreading in some areas and fluctuations in powder bed density, affecting the forming quality.

Method used

By introducing an adjustment unit between the powder spreading unit and the mounting part, the distance between the powder spreading unit and the powder spreading plane can be adjusted. An adjustable powder spreading component structure is adopted, including adjustment holes, connectors, fixing parts and guide units, to achieve flexible adjustment of height and angle.

Benefits of technology

It improves the uniformity and density of powder laying, enhances forming quality, simplifies the adjustment structure, and reduces equipment costs.

Abstract

The application provides a powder spreading assembly (1) and an additive manufacturing device with the same, comprising a mounting part (10), a powder spreading unit (11) and one or more adjusting units (12), the powder spreading unit (11) is used for moving along a powder spreading direction to spread powder to a forming area; the one or more adjusting units (12) are respectively connected with the mounting part (10) and the powder spreading unit (11), and the one or more adjusting units (12) are used for adjusting the distance between the powder spreading unit (11) and a powder spreading plane. The powder spreading assembly (1) can adjust the gap between the powder spreading unit (11) and the powder spreading plane according to actual powder spreading requirements, without frequent replacement of the powder spreading unit (11) or adjustment and calibration of the forming platform, so that the powder spreading unit (11) adjusting structure is simplified and the equipment cost is reduced.
