Selective Laser Sintering (SLS)
The Fuse 1 is the first benchtop industrial SLS 3D printer that offers high quality, compact footprint, and a complete, simplified workflow at a fraction of the cost of traditional industrial SLS systems.

Selective Laser Sintering (SLS)
For the same price level, the Lisa Pro offers 2-3X smaller build volume, a more complex and messy workflow, but currently more material options. 

Build Volume (W × D × H)

The large build volume of traditional SLS printers in a compact form. Depending on the material, 2-3X larger builds than the Lisa Pro.


Fuse 1: 
16.5 x 16.5 x 30 cm
6.5 x 6.5 x 11.8 in

Limited build volume, especially for the most popular nylon materials.


Lisa Pro
Nylon: 9 x 13 x 23 cm
3.5 x 5.1 x 9 in

TPU, TPE: 11 x 15 x 24.5 cm
4.3 x 5.9 x 9.6 in


Four popular materials, more coming soon
The Fuse 1 currently prints with Nylon 12, Nylon 12 GF, Nylon 11, and TPU. Nylon 12 is a general purpose, versatile material with high detail and great dimensional accuracy. Nylon 11 is a ductile, strong, flexible material for when durability and performance are key. Nylon 12 GF is a glass-filled material with enhanced stiffness and thermal stability for demanding industrial environments. TPU 90A Powder is a tough elastomer for producing resilient, skin-safe products. More materials are coming soon.

Seven materials, but complex changeover 
The Lisa Pro prints with Nylon 12, Nylon 11, Nylon 11 CF, Nylon 11 ESD, PP, TPE, and TPU.  Some of these materials require an inert gas environment to print reliably. Switching between materials requires lengthy manual clean-up.

Ease of Use

Plug and print
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. Easy workflow empowers anyone at your company to use the system independently after a quick online or in-person training.

Complex and messy
From a lengthy print setup to a long list of manual tasks, the workflow is more complex and less intuitive. The steeper learning curve means that it’s recommended to have a skilled technician to operate and maintain the printer.


The Fuse 1 is designed for nonstop throughput. It comes with a removable build chamber and industry-leading cooldown times, allowing you to start new prints within 1-2 hours after the previous print has finished and minimize downtime.

The Lisa Pro has a 2-3x smaller build chamber that is not removable, which means that you have to wait until the build fully cools down and carry out maintenance before starting the next print.


All in one
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.

Messy and labor-intensive
Sinterit offers powder handling and sieving tools, but the post-processing workflow is much more involved, requiring users to manually transfer, measure, pour, brush, and mix volatile powders in open-air environments at several points in the process.


The Fuse 1 is designed for minimal upkeep. The system offers proactive maintenance alerts and a full-color touchscreen interface guides you through every step of printing and maintenance.

A less user-friendly workflow means that the operator has to carry out a long list of manual maintenance steps between each print.


Free and easy to use
Formlabs' free print preparation software, PreForm, makes it easy to set up a print in minutes and offers advanced tools to manually refine as needed. Try it now. You can also use the online Dashboard to manage printers, materials, and teams. Available for Windows and Mac.

Paid tier recommended
Sinterit’s basic print preparation software is included with printer, but using additional materials requires a paid upgrade. Available only for Windows.


Premium service
Up to five years of premier support service with direct phone and email support, customized remote training, on-site visits and repairs from local certified SLS experts, annual preventative checkups, and worry-free warranty — all for an affordable price.

Limited Plans and Services
Maximum two years of warranty and service, with some benefits only available in Europe.

A Convenient, Intuitive Workflow

Fuse 1 and Fuse Sift

Fast, Simple



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.

SLS made

During setup and printing, an intuitive Touch UI walks you through every step.

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.

Track printers, teams, and supplies via the cloud-based Dashboard.

Reliable, consistent

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.

With patent pending Surface Armor technology, a semi-sintered shell that prints around the surface of the part, the Fuse 1 provides competitive mechanical properties and surface finish without the prohibitive cost or hassle of competitor systems.

Powder Recovery

Safe, efficient
powder recovery.

Our all-in-one powder recovery station, Fuse Sift, combines part extraction, powder recovery, storage, and mixing in a single device.

Produce fully-functional parts at a 30% powder refresh rate—with unlimited cycles. This means you can print with up to 70% recycled powder.

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