Product Description
1. Overview of Selective Laser Sintering (SLS) Technology
Selective Laser Sintering (SLS) is a powder bed-based additive manufacturing technology that selectively sinters powder materials layer by layer using a high-energy laser beam to form three-dimensional solid parts. This technology has the following characteristics:
Technical Advantages:
- Extremely high design freedom: no need for support structures, capable of manufacturing complex internal cavities, irregular channels, and other structures difficult to achieve with traditional processes
- Wide material selection: supports various engineering materials such as nylon, TPU, metals, etc.
- Outstanding functionality: finished products have mechanical strength close to injection molded parts, with some performance indicators even better
- Rapid response: from design to prototype can be completed in as fast as 24 hours
Technical Limitations:
- Relatively high surface roughness: native surface Ra 6.3-12.5μm, usually requires post-processing
- Dimensional accuracy is limited: anisotropic shrinkage affects final dimensional accuracy
- High equipment investment: initial investment cost is relatively high
