Formlabs Launches the Fuse 1 3D Printer

It was a good start to 2021 when Formlabs announced that they are now able to start shipping their highly-anticipated the Fuse 1 which was first revealed in 2017.

Here’s what you need to know about the Fuse 1:

Fuse 1

The Fuse 1 uses Selective Laser Sintering (SLS) technology which can manufacture highly complex and intricate parts with unique geometries. This is marketed as the world’s first benchtop industrial SLS machine

SLS technology uses a high-powered laser to selectively ‘sinter’ material as opposed to a mechanical print head as used in FFF technology. The laser is able to achieve a greater range of motion and scale.


The Fuse 1 prints industrial-grade Nylon powder. The powder is printed one layer at a time on the print bed. The laser then traces a pattern in the nylon powder, one layer at a time, to bond and harden the nylon layers together.

Nylon is an engineering material with outstanding mechanical properties, such as high tensile strength and extreme abrasion resistance. It’s the material of choice for prototyping in most industries, from automotive to consumer electronics.

At the moment only Nylon 12 is available now. It’s a rigid material with a 50MPa tensile strength rating with 12% elongation at break.

Other materials are in development and are expected to be released over the following months.


Build Volume and Features

The Fuse 1 has a 165 x 165 x 300 mm (6.5 x 6.5 x 11.8 in) build volume and the maximum build speed is 10 mm / hour (0.39 in / hour). It prints down to a layer height of 110 microns (0.004 in) with a laser spot size of 200 microns (0.0079 in).

There’s a 10.1” touchscreen built into the top of the printer with an impressive 1280 × 800 resolution. You can control the printer from this panel, or you can monitor and control the process from a computer, laptop or mobile device in Printer Dashboard. You prepare prints using the free PreForm Desktop Software.

Additionally, Formlabs has also launched Fuse Sift, a post-processing system for the Fuse 1 to provide users with an end-to-end SLS workflow. This machine is an all-in-one powder recovery system that extracts, recovers, stores and mixes nylon powder for you. It has a 30% material refresh rate, so in theory, you can print with up to 70% recycled powder, indefinitely.



In our opinion, it’s a brilliant product that changes the game for desktop 3D printing. Why? Because SLS is capable of producing highly complex functional prototypes at great speed and scale.
