Selective Lazer Sintering also known as Powder Bed Fusion is a 3D printing process where a thermal energy source will selectively induce fusion between powder particles inside a build area to create a solid object.

Many Powder Bed Fusion devices also employ a mechanism for applying and smoothing powder simultaneous to an object being fabricated, so that the final item is encased and supported in unused powder.

  • Types of 3D Printing Technology: Selective Laser Sintering (SLS).

  • Materials: Thermoplastic powder (Nylon PA11, Nylon PA12).

  • Dimensional Accuracy: ±0.3% (lower limit ±0.3 mm).

  • Common Applications: Functional parts; Complex ducting (hollow designs); Low run part production.

  • Strengths: Functional parts, good mechanical properties; Complex geometries.

  • Weaknesses: Longer lead times; Higher cost than FFF for functional applications.
