Process Performance Insights:

  • Direct Metal Laser Sintering (DMLS): Known for high precision and fine surface finish (Ra < 10 µm), DMLS is ideal for producing parts that require tight tolerances and smooth surfaces. Commonly used for aerospace and medical applications where complex geometries and high strength are required.

  • Selective Laser Melting (SLM): Offers similar benefits to DMLS, with high-speed production and precision. SLM is ideal for structural components, turbine blades, and other aerospace applications requiring high mechanical properties.

  • Electron Beam Melting (EBM): Suitable for parts exposed to extreme temperatures, especially in aerospace and energy applications. EBM has a slower build speed and a rougher surface finish, but it provides high material strength, making it ideal for critical load-bearing components.

  • Powder Bed Fusion (PBF): Provides excellent precision and smooth surface finishes for stainless steel parts. It’s ideal for manufacturing intricate components with tight tolerances, such as medical devices, engine components, and other industrial parts.
