SLS 3D Printing Technology

CHOOSE ROBUST SLS FOR COMPLEX, TOUGH, FUNCTIONAL PARTS

What is Selective Laser Sintering (SLS)?

Selective laser sintering is a powder-based 3D printing technology that uses a laser to fuse material layers into a final part. After the laser traces a cross-section of the CAD design(s) onto a material layer, the build platform lowers and another layer is fused on top. The build platform continues to lower until every layer is built and the part is complete. 

3D Systems’ SLS materials include a range of optimized nylon and elastomeric powders.

SLs 3D Printing Technology

SLS uses production-grade nylon materials, resulting in durable, functional parts that last. In fact, SLS printed parts rival other parts produced using traditional manufacturing methods. The robustness of SLS makes this technology great for:

  • Complex and durable production parts
  • Production and prototype parts that need to withstand high-heat environments or chemical exposure
  • Impact resistant parts
  • Parts with snap fits/living hinges
  • Automotive design
  • Aerospace parts and ducting, flame-retardant parts
  • Low-volume production and mass customization solutions
  • Medical devices
  • Jigs, fixtures and tools
  • Investment casting patterns
  • Elastomeric and urethane parts, such as gaskets, seals and hoses

Selective Laser Sintering (SLS) 3D Printers
3D Systems’ SLS is an integrated solution of hardware, software, and fine-tuned nylon and composite materials that combine to deliver robust, high-resolution parts at high throughput.

The surface finish, resolution, repeatability, and accuracy of SLS enable increased manufacturing agility with a low total cost of operations.

Our SLS printers use 3D Sprint® all-in-one software for plastic printing to prepare and optimize CAD data, and manage the SLS printing process. Tools for high-performance—such as high-density automatic 3D nesting, quality checks for pre-build verification, repair options, print queue tool for efficient build planning, cage structure generator for small parts enclosure, and more features—bring increased productivity and quality to your SLS production process without needing additional third-party software.

From medium to large frame, we offer SLS printing solutions with different build volumes, levels of automation, and a large variety of materials.

SLS build platform with 198 parts, automatically positioned and nested using 3D Sprint

Nylon / PA 12

Strong polyamide 12 thermoplastics that can replace traditionally injection molded articles; includes food-grade, medical-grade, and flame-retardant capable options.

Filled Nylons / PA

Engineered for greater end-use part performance, these materials are developed with glass, aluminum, or mineral fiber fillers to offer a range of advanced properties in terms of stiffness, temperature resistance, strength, and surface finish.

Nylon / PA 11

Impact-resistant polyamide 11 thermoplastics that offer molded-part performance in harsh environments; ideal for snap-fits and living hinges with the flexibility to bounce back to the original shape.

Elastomeric Thermoplastics

Rubber-like flexibility for prototypes and production parts with excellent memory, tear, and abrasion resistance.

Castable Polystyrene

Great for sacrificial patterns for prototype metal castings and low to medium production runs without tooling.
