High Performance Selective Laser Sintering (SLS)


Meet the Formlabs
Fuse 1

A new wave of independent manufacturing and
prototyping starts now with the Fuse 1.

Bring production-ready nylon 3D printing onto your
benchtop with an affordable, 
compact selective laser
sintering (SLS) platform. 




The Fuse 1 is designed for minimal upkeep. A full color touchscreen interface guides you through every step of printing and maintenance.


With reduced equipment cost, affordable material, and efficient powder recycling, the Fuse 1 is the smart choice for industrial quality SLS 3D printing.


From print setup to powder recovery, our easy-to-use hardware and software are designed to maximize your efficiency at every step of the process.


Fast, simple print setup


Use Formlabs PreForm print preparation software (free to download and try) to import STL or OBJ part files, orient and arrange models, estimate print times, monitor your printers, and upload job files.

PreForm’s part packing algorithms can automatically arrange many models in a build.

The touchscreen displays a live stream of the print bed so you can watch each new layer take shape.

This camera view is also available from your computer in PreForm so you can monitor your print without leaving your desk.

SLS made manageable

Designed for nonstop throughput


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.


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.

Reliable, consistent printing

Balancing Strength and Detail 


Nylon 12 Powder is a highly capable material for both functional prototyping and end-use production of complex assemblies and durable parts with high environmental stability.


Our Nylon 12 Powder is specifically developed for use on the Fuse 1.

Nylon 11 Powder

For ductile, robust parts, Nylon 11 Powder is our higher performance, bio-based nylon material for functional prototyping and small batch production. Nylon 11 Powder is suitable for printing parts that need to bend or take impact.


Is certified biocompatible.

Why Choose Nylon 11 Powder?

Nylon 11 Powder is a ductile, strong, flexible material for when durability and performance are key.


High Ductility - Print end-use parts that can handle wear and tear over time.


Thin Walls - Print enclosures, ducts, and other geometries with ease using Nylon 11 Powder.


No Nitrogen Purge - 3D print in Nylon 11 in-house without the hassle of other SLS 3D printers.


Environmental StabilityNylon 11 prints absorb very little moisture and are resistant to light, heat, and chemicals.

Applications - Nylon 11 parts can handle wear and tear over time. For higher performance functional prototyping and end-use products that can take an impact and keep going, choose Nylon 11 Powder.

Fuse Sift completes the Fuse 1 workflow

Fuse Sift

All-In-One Powder Recovery 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 the most functionality you'll get in a single device on the SLS market.

Fuse Sift Dimensions

Compact, enclosed system

A negative air pressure system keeps powder inside while enabling open access and easy cleanup.


Low waste

A 30% material refresh rate means you can print with up to 70% recycled powder, indefinitely. Fuse Sift’s sieve filters out particles to be remixed with new powder and reused in future prints.

Automatic powder mixing

Fuse Sift will dispense and mix used and new powder automatically so you can reduce waste and control your powder supply.

A complete toolkit

The Fuse Sift includes a set of finishing tools to help you clean excess powder from parts with ease.
