Layer Thickness Regulation in Powder Bed
Layer thickness regulation in the powder bed ensures that the powder amount per production layer remains constant. This guarantees consistent part quality and prevents defects.
Physicochemical Mechanism of Action
Layer thickness control in the powder bed regulates the amount of powder applied to each build layer. This is done through precise control of the coating system, which regulates the flow and density of the powder.
Metallurgical Relevance & Welding Risks
Uneven layer thickness can lead to component defects, like incomplete melting or structure inhomogeneities. This can hurt the strength and toughness of the parts and cause cracks.
Workshop Practice & Instructions
To ensure a constant powder amount, these steps are needed:
1. Set the correct layer thickness specified for the material and process.
2. Continuously monitor the powder amount on each build layer and adjust if needed.
3. Use high-quality powder to ensure even coating.
