Layer Thickness Compensation Algorithm
The layer thickness compensation algorithm corrects the Z-axis feed to avoid build-up errors when the energy input in the powder bed fluctuates. It ensures a uniform layer thickness.
Physical-Chemical Mechanism of Action
The algorithm monitors energy input and layer thickness in real time. When fluctuations occur, it corrects the Z-axis position to ensure a constant layer thickness.
Metallurgical Relevance & Welding Risks
Without compensation, fluctuating energy storage and release can lead to uneven build defects. This can cause porosity, non-uniform layer thickness, and poorer mechanical properties of the final product.
Workshop Practice & Action Guidelines
Implement the algorithm into the software and calibrate it regularly using test parts. Continuously monitor the layer thickness measurement and adjust settings accordingly to achieve optimal layer thickness.
