Durable, end-use quality

SLS parts are strong, heat-resistant, and chemically resistant – ready for real-world applications and demanding environments.

Scalable production capabilities

From one-off prototypes to thousands of parts, SLS is perfect for bridge manufacturing and low-volume production runs.

Applications

Selective Laser Sintering technology, also called SLS, builds with a CO₂ laser that selectively melts cross-sections of a design in powdered thermoplastic material, creating a 3D structure. Nylon is the most popular base material for SLS, and it can be combined with plastic, ceramic, glass, metal, or other materials for more robust parts.

Precision and Durability

SLS technology is unique in that parts are built within a powder bed, eliminating the need for support structures. This allows designers and engineers to incorporate complex internal features such as ducts, undercuts, and intricate geometries without the risk of damaging the part during the removal of supports. This also reduces post-processing time and effort, making the process more efficient.

Key Benefits:

Support-Free Design: The powder bed eliminates the need for supports, enabling more complex designs and reducing post-processing.
Material Flexibility: SLS can produce parts that are durable, tough, flexible, or lightweight, depending on material selection and design requirements.
Durable and Lightweight Parts: Parts created using SLS are ideal for functional prototypes and end-use applications where strength, toughness, and lightweight properties are needed.
Versatile Material Options: From impact-resistant engineering plastics to flame- or chemical-resistant materials, SLS can produce parts capable of withstanding harsh and demanding environments.
