Selective Laser Sintering (SLS) is an industrial 3D printing process ideal for manufacturing end-use parts. In SLS, a laser selectively sinters polymer powder particles, fusing them together and building a part layer-by-layer. SLS produces functional plastic parts with isotropic mechanical properties that can be used for detailed prototyping or end-use low-volume production.
Rapid Turnaround : Speedy turnaround for prototypes and parts
Real Thermoplastics : FDM has the highest variety of real engineered thermoplastics.: heat and chemical resistant, flame retardant, biocompatible, and high strength materials available
Low cost : Most affordable 3d printing technology for custom parts.
Large Build : Parts with large build volumes up to 600 x 500 x 500 mm can be made.
Surface Quality : Extruding material layer-by-layer,the surface has layer lines and fine details cannot be realized.
Layer Adhesion : Parts have an anisotropy in the z-direction (vertical direction), and properties are weaker than base materials.
Scale Effect : The unit cost and lead time will not be reduced as much as casted or molded parts.
SLS Design Guidelines and Capabilities
SLS materials for prototyping are typically chosen for their ease of use, speed, and cost-effectiveness, focusing on enabling rapid design iterations and validation. Materials for production are selected for their durability, specific mechanical properties, and long-term performance, ensuring they meet standards for end-use applications.
