SLS 380



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 Material Properties & Uses


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 nylon

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 pa11

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.

sls castable

Castable Polystyrene

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

Why Use SLS?

sls throughput

High Speed and Throughput

Large SLS build capacities paired with fast build times, high-density nesting, and no support structures help you maximize every print for more parts, sooner.

SLS quality

Best-In-Class Part Quality

Side-by-side comparison testing shows 3D Systems SLS printers provide best-in-class part quality.* Get superior accuracy, part resolution, edge definition, and surface finish with 3D Systems’ SLS solutions.

sls design

Functional Design

As a self-supporting build methodology, SLS enables the production of complex geometries, such as monolithic designs, lightweight components, and mass-customized products, that could not be manufactured any other way.

sls cost

Low Part & Ownership Costs

The features and capabilities of 3D Systems’ SLS deliver up to 20% lower operational costs compared to similar printers. These include automated production tools, high throughput, material efficiency, and repeatability, just to name a few.

Robust, Performance Parts

SLS technology produces tough and durable parts that excel in high-performance prototyping and end-use applications. 3D Systems’ DuraForm® SLS materials have been optimized, validated, and tested to ensure quality, with uniform 3D mechanical properties.
