Select Laser





Produce tough, durable parts from a range of production-grade nylon materials that have been optimized, validated, and tested to ensure quality, with uniform 3D mechanical properties. The ProX SLS 6100 brings versatility to your applications, whether for functional prototyping or direct 3D production. Choose from industrial-grade nylon 11 with DuraForm ProX EX BLK or DuraForm ProX PA nylon 12, the flame retardant nylon 12 based powder of DuraForm ProX FR1200, fiber-reinforced DuraForm ProX HST, glass-filled DuraForm ProX GF, and aluminum filled DuraForm ProX AF+. DuraForm ProX PA can meet the standards of ISO 10993-5 and 10, opening the door to production of select medical devices.


Production Quality, Priced for Prototyping


Automated production tools, new air-cooled laser, remarkably high throughput, 95% material efficiency and repeatability plus a competitive initial purchase price combine to deliver a 20% lower total cost of operations over similar printers. The material quality control (MQC) system provides automatic blending and recycling while providing transportation of material to the printer without manual intervention


Unmatched Part Quality at High Throughput


With faster build times than other SLS printers in its price point, high performance nesting and high-density capability for a 25% larger build volume capacity, the ProX SLS 6100 delivers production quality parts in a fast and efficient process.

  • Best surface finish

  • Highest resolution and edge definition

  • High accuracy and repeatability

  • Uniform part properties


Advance Your Workflow with 3D Sprint


Use this exclusive 3D Systems additive manufacturing software 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 all bring increased productivity and quality to your SLS production process.

Maximize Your Production with 3D Connect


3D Connect Service provides a secure cloud-based connection to 3D Systems service for preventative support to enable better service, improved uptime, and production assurance for your system. Through 3D Connect Manage, you can also manage and monitor your equipment with anytime, anywhere access to your print jobs, system performance metrics, and usage.
