Selective Laser Sintering (SLS)

Sintered parts, or SLS models are ideal when you need tough, stable parts for harsh environment testing or end-use applications. The use of sintering enables you to eliminate tooling cost and drastically reduce your time and cost of your product development or production.

Agile uses next generation, high precision, production SLS technology from 3D Systems, a global leader in total laser sintering solutions. Choose from the widest selection of materials with properties close to or matching the properties of injection molded parts and get ready-to-use, quality parts.

SLS parts are ideally used for form, fit and function testing and direct manufacturing applications. Key benefits include:

  • Great accuracy
  • Robust
  • Consistent part characteristics
  • Design to tool-less production runs in one step
  • Widest range of materials offering
  • DuraForm FR UL94 Flame Retardant Material
  • Multiple finishing options

Parts: 1 to 1000+

Shipped in: 2 to 4 days

Pricing: Starting at $50

Excellent for:

  • End Use Parts
  • Testing Models
  • Low Volume Manufacturing

How SLS Works

SLS uses a high-powered C02 laser to fuse small particles of powdered material to create 3 dimensional parts. The laser selectively fuses powdered material by scanning X&Y cross-sections on the surface of a powder bed. Once a layer is completed, a roller distributes another layer of powder across the entire bed and the sintering process begins again, adding height to the previous layer. The model is built complete to the supplied 3D CAD data.

Once the build is complete, the build is removed and excess powder is carefully broken away from the model. The part is then finished in a tumbler, bead blaster, or by hand to the desired finish level. SLS parts can be coated, smoothed, or dyed.

TOLERANCES

Most parts can be accuratley produced within .005″ or less on the X/Y axis and .010″ on the Z (per inch).

BUILD ENVELOPE

SLS parts can be made up to 22 x 22 x 18″ in size, or multiple parts nested in a single build.

BEST APPLICATIONS

SLS is best suited for functional prototypes, end use parts, and when flame retardant materials are required.
