Layer Thickness Regulation
Layer thickness regulation controls the powder layer thickness during the additive manufacturing process to avoid re-melting and incomplete bonding.
Physical-Chemical Mechanism of Action
Layer thickness regulation ensures that the powder layer is always uniform and thin. This is achieved by precise monitoring of the layer thickness during deposition. Layers that are too thin can lead to incomplete bonding, while layers that are too thick can cause re-melting and missing areas in the part.
Metallurgical Relevance & Welding Risks
Incorrect layer thicknesses can lead to parts that do not meet specified properties. Re-melting can contaminate the material and impair strength, while incomplete bonding can lead to fractures or weak points in the part.
Workshop Practice & Action Guidelines
To ensure effective layer thickness regulation, the following measures must be observed:
1. Use a high-resolution laser system with precise layer thickness control.
2. Ensure that the powder flow is continuous and uniform.
3. Continuously monitor the layer thickness and correct the laser system settings as needed.
4. Keep the part build area clean and free of contaminants to ensure optimal bonding.
