What features do you get? 

  • Nylon 11 & 12 are both strong, functional materials developed exclusively for the Fuse 1, meaning you can 3D print production-ready, end-use parts. Keep an eye out for more strong, versatile materials being released for the Fuse 1 regularly! 
  • SLS 3D printing fuses nylon powder layer by layer. The unused powder supports the parts during printing so you can create complex, interconnecting designs with no need for support structures. 
  • Material recycling at its best. The Fuse 1’s unique powder recovery station, the Fuse Sift guarantees you safe and efficient powder recovery by fitting your printed part extraction, powder recovery, storage, and mixing into one single, easily maintained device that enables you to produce fully functional parts at a 30% powder refresh rate across unlimited cycles! 
  • Add a second removable build chamber, compatible with the Fuse 1 and Fuse Sift, to enable continuous printing and reduce downtime. Industry-leading cooldown times allow you to start a print 1–2 hours after your previous print has finished. 
  • Formlabs PreForm print preparation software easily and intuitively imports STL or OBJ part files, orients models, estimate print times, monitors your printers, and uploads job files. 
  • The touchscreen can display a live stream of your print bed. Watch each new layer take shape, available from your computer in PreForm so you can monitor your print without leaving your desk.

Complete Your 3D Printing Workflow  

Get more done and work more efficiently with an end-to-end 3D printing workflow. From printing to post-processing, each step of the process was designed with efficiency in mind. Add the Fuse Sift to your SLS workflow to streamline and automate your post-processing. 


The all-in-one powder recovery system for the Fuse 1 

  • The Fuse Sift is a safe, efficient powder recovery system for the Fuse 1. This all-in-one station combines part extraction, powder recovery, storage, and mixing in a single free-standing device. Highly convenient and compact, this is the most functionality you’ll get in a single device on the SLS market. 

Nylon 11

  • Nylon 11 Powder is the Formlabs high performance nylon powder option for high impact prints on the Fuse 1. Highly ductile and ideal for functional prototyping or small batch production, Nylon 11 is more flexible, less brittle, and better for printing thin walls than its Nylon 12 counterpart.


Try Nylon 11 Powder for:


  • Impact-resistant prototypes, jigs, and fixtures
  • Thin-walled ducts and enclosures
  • Snaps, clips, and hinges
  • Orthotics and prosthetics

Nylon 12


  • Designed as the flagship material for the Fuse 1, Nylon 12 Powder excels at balancing strength and fine detail. Nylon 12 is ideal for both functional prototyping and the end-use production of complex assemblies and durable parts with high environmental stability.


Try Nylon 12 Powder for:


  • High performance prototyping
  • Small batch manufacturing
  • Permanent jigs, fixtures, and tooling
  • Biocompatible, sterilizable parts

Nylon 12 GF

  • A glass-filled material with enhanced stiffness and heat resistance to endure demanding manufacturing conditions. Ideal for applications where structural rigidity and thermal stability are critical.


Try Nylon 12 GF Powder for:


  • Robust jigs and fixtures
  • Parts undergoing sustained loading
  • Replacement parts
  • Threads and sockets
  •  High-temperature applications
