Selective Laser Sintering (SLS)

General Purpose Volume Production & Prototyping 

Functional Parts

Parts built in 2-5 Business Days

Selective Laser Sintering (SLS) is an additive manufacturing process that uses powdered thermoplastic polymers. Layers are fused together using a laser that selectively sinters the particles of the powder and binds it together to create a solid structure. SLS offers fantastic throughput with its unique ability to nest thousands of parts within the boundaries of the machine.

Parts produced using SLS provide a uniform finish with excellent mechanical properties and abrasion resistance, making it suitable substitute for injection molding as well as functional prototyping alike. Bio compatibility certifications fulfill requirements for end-use-applications in medical products.

Nylon PA 12

Tough & Durable parts for Prototyping & Production

PA12 (PA 2200) is a highly functional polyamide material that provides a consistent surface finish, with excellent resolution and feature detail. PA 2200 is ideal for both functional prototyping as well as end use applications that require complex thin wall parts, chemical resistance, snap fits and/or low vibration resistance. PA 2200 is biocompatbile according to EN ISO 10993-1 and USP/Level VI/121 °C

  • Durable

    Create functional parts with consistent durability that are capable of being used in end-use, low-volume production at competitive prices.

  • Production Quantities

    The scability of SLS allows small production runs of end use parts with material properties similar to injection molded parts.

  • Accurate

    Ideal for thin wall parts, SLS is uniquely capable of replicating small features with crisp details and a consistent surface finish.

  • Large Builds

    Produce parts with build volumes up to 22″ x 22″ x 30″ to produce large, complex parts in a single build.
