Powder Bed Fusion (SLS, EBM)
Powder bed fusion is a category of 3D printing techniques that includes Selective Laser Sintering (SLS) and Electron Beam Melting (EBM). These methods use powdered materials that are fused using thermal energy, enabling the production of metal and ceramic objects without the need for support.
SLS 3D printers utilize a laser to selectively fuse the powder particles, while EBM 3D printers use an electron beam for the same purpose. Both techniques result in strong and durable prints with excellent dimensional accuracy.
Selective Laser Sintering (SLS)
Selective Laser Sintering (SLS) is a powerful 3D printing technique that offers a wide range of applications, especially in the field of manufacturing. SLS printers are capable of producing functional and intricate parts using various materials, including polymer powders, metal powders, and ceramic powders.
The SLS process involves a laser selectively fusing the powder particles, layer by layer until the final object is formed. The powder bed acts as both the printing material and the support structure, allowing for complex geometries and designs.
Electron Beam Melting (EBM)
Electron Beam Melting (EBM) is a specialized powder bed fusion technique that is primarily used for manufacturing metal parts. EBM printers utilize an electron beam to selectively melt and fuse metal powders, resulting in high-quality, fully dense metal objects.
This technique is particularly suited for complex, high-temperature, and bio-compatible applications. It allows for the production of functional metal parts with excellent mechanical properties. However, EBM 3D printers are less common and require specialized equipment and materials.
