Layer Thickness Optimization in Powder Bed
Layer thickness optimization in powder bed reduces surface roughness and process defects by precisely adjusting the vertical powder deposition height, significantly improving part density.
Physicochemical Mechanism of Action
Layer thickness in the powder bed affects the density and surface roughness of the final part. Too thin a layer can cause air bubbles and process defects, while too thick a layer reduces density and makes the material behave unevenly.
Metallurgical Relevance & Welding Risks
An optimal layer thickness minimizes process defects and increases part density. Too thin or too thick layers can lead to cracks, air bubbles, and uneven processing, affecting overall calibration and the final product.
Workshop Practice & Action Guidelines
To achieve optimal layer thickness, set the vertical powder application height to 0.3 to 0.5 mm. This range minimizes surface roughness and process defects without compromising part density. For special materials or process requirements, layer thickness can be slightly adjusted, but always stay within 0.2 to 0.6 mm.
