How it works
01
Prepare
Set up parts in PreForm and organize entire jobs, across builds, materials, and printers, in a single project file.
02
Quick-connect build chambers, automated powder loading, and no optics cleaning between prints. Hit print and walk away.
03
Unpack
Move the build chamber straight into the Sift X1, where an integrated glovebox and compressed air make breakout fast, clean, and contained.
04
Clean and Polish
Automated cleaning and polishing in the Fuse Blast, with a 50% larger basket for bigger parts and easy removal for large-format work.
05
Refresh and Load Powder
Use the Vacuum Transport System to load used and new powder into the Mix Kit and refresh the material for your next print, making the loading process just as easy.

Performance
Productive no matter how you measure it. Fuse X1 delivers 3× higher throughput in less than half the floor space.
More Parts Per Build
With 30%+ packing density and a 61.5L build volume, the Fuse X1 fits more parts in a single build than competing industrial SLS and MJF systems — adding up to thousands more parts per week.
Fits Where Others Can't
At just 1.3 m², the Fuse X1 takes up less than half the floor space of an HP 5600 (2.80 m²) or EOS P3 Next (2.70 m²). It rolls through a standard doorway, so you can install production-scale SLS without rebuilding your floor plan.
Engineering
The Power Behind the Fuse X1
Adaptive Thermal Control
Using thermal imaging, Adaptive Temperature Control collects and processes 700 times more data per second than the Fuse 1+ 30W. That data drives 13 independent thermal zones that deliver, maintain, and sinter powder at an incredibly precise and stable temperature from the first layer to the last, giving you unlimited packing freedom and exceptional part quality.

Customer Spotlight
How Tesla Prints 10,000–30,000 Parts a Week with the Fuse X1
Tesla's Additive Manufacturing team at Giga Nevada needed to deliver most printed parts in under 24 hours — a challenge that traditional large-format SLS printers couldn't meet at full build height. With the Fuse X1, they unlocked the full 565 mm Z-height within a single production cycle.

“With the increased throughput and decreased costs, Fuse X1 has completely changed our perspective on what kinds of projects our lab can support versus what we would have traditionally moved to an injection mold.”

How Radio Flyer Cut Prototype Time from 2 Months to 2 Days with the Fuse X1
Radio Flyer's product development team needed to rapidly prototype large consumer products like the Flyer Loop Cargo eBike. Their old process — metal frames covered with dozens of glued 3D-printed sections — took two months per prototype. With the Fuse X1, they now print an entire eBike frame in two overnight builds and iterate three times as often.
