AI Technical Summary
In powder bed additive manufacturing technology, there are problems such as uneven distribution, accumulation and voids in the powder spreading process of ultrafine powder, which leads to porosity, interlayer separation and uneven surface roughness during manufacturing, thus limiting the forming accuracy and performance of parts.
A powder spreading device is employed, comprising a powder spreading arm, a support base, a vibrating component, and a vibration limiting part. The vibrating component applies vibration during the powder spreading process, and the vibration limiting part limits the vibration amplitude in the vertical direction to ensure that the vibration energy mainly acts in the horizontal direction. Different materials and driving methods are combined to optimize powder distribution.
It improves the uniformity of powder layer spreading, reduces wavy undulations, ensures close contact between layers and system stability, and enhances the forming accuracy and performance of parts.
