Five years after introducing the original Fuse platform, Formlabs has unveiled the machine many manufacturers have been waiting for. The new Fuse X1 is far more than a larger version of the Fuse 1. It represents a complete industrial selective laser sintering (SLS) ecosystem designed to compete directly with traditional six-figure systems from established industry leaders.
With a starting price of $85,000, massive build volume, and production-level throughput, the Fuse X1 brings industrial SLS capabilities within reach of businesses that previously considered the technology financially out of reach.
How SLS 3D Printing Works
Selective laser sintering uses a laser to fuse layers of nylon powder into solid parts. Unlike many other additive manufacturing processes, SLS requires no support structures because unfused powder naturally supports the geometry during printing.
This enables the production of highly complex parts featuring:
- Internal channels
- Interlocking assemblies
- Thin walls down to 0.5 mm
- Production-grade nylon components
- Excellent surface finish
- Chemical resistance and durability
These characteristics have made SLS one of the most desirable technologies for functional manufacturing applications for decades.
Industrial SLS Has Traditionally Been Expensive
For over twenty years, industrial SLS systems have largely been dominated by companies such as EOS and 3D Systems, while HP established itself with Multi Jet Fusion (MJF) technology.
These systems deliver exceptional performance, but they were designed primarily for large manufacturing facilities and enterprise environments. Purchase prices often begin around $150,000 and can easily exceed $300,000, with some systems reaching half a million dollars or more.
That high barrier to entry created an opportunity for Formlabs to rethink industrial SLS from the ground up.
The Fuse X1 Starts at Just $85,000
One of the biggest advantages of the Fuse X1 is its price.
Starting at approximately $85,000, the system costs significantly less than competing industrial SLS and MJF platforms while delivering comparable manufacturing capabilities.
For many service bureaus, engineering departments, and production teams, this pricing dramatically changes the economics of industrial additive manufacturing.
No Three-Phase Power Required
Traditional industrial powder bed systems often require:
- Three-phase 400-volt electrical service
- Facility modifications
- Special installation requirements
- Dedicated powder rooms
- Large floor space allocations
The Fuse X1 takes a different approach.
It runs on standard single-phase 240-volt power, similar to what many shops already use for dryers or other common equipment. No extensive electrical upgrades or major facility changes are necessary.
With a footprint of roughly 14 square feet, the machine fits comfortably into existing workspaces and can pass through standard doorways without special accommodations.
A Build Volume Eight Times Larger Than the Fuse 1+
One of the most exciting upgrades is the machine’s build chamber.
The Fuse X1 offers a build volume measuring approximately:
- 13 inches × 13 inches × 22 inches
That 22-inch height allows users to produce parts approaching two feet long in a single print, eliminating the need for splitting and bonding components together.
Compared to the Fuse 1+ 30W, the X1 delivers roughly eight times the available build volume while remaining far below the price of competing industrial machines with similar capacities.
Higher Packing Density Means More Parts Per Build
SLS technology excels because parts can be stacked throughout the entire powder bed. Components can be nested above, below, and even inside one another without requiring support structures.
The Fuse X1 achieves packing densities exceeding 30%, allowing manufacturers to maximize throughput and increase productivity.
According to Formlabs, the system can deliver up to three times the throughput of competing machines while producing thousands of parts within days.
Lower Cost Per Part and Injection Molding Economics
By fitting more components into every build, the Fuse X1 can reduce cost per part by as much as 50% compared with older powder-bed technologies.
This creates compelling economics for low- and medium-volume production runs.
For quantities reaching tens of thousands of parts, Formlabs reports that the system can become cost competitive with injection molding, without requiring:
- Steel tooling
- Long lead times
- Minimum order quantities
- Large inventory commitments
Manufacturers gain the flexibility to print only what they need when they need it.
An Integrated SLS Workflow Designed for One Operator
Powder handling has traditionally been one of the biggest challenges associated with industrial SLS systems. Formlabs addresses this with an interconnected ecosystem of specialized equipment.
Fuse X1 Printer
The printer focuses solely on production. Finished build units can be removed while a fresh unit is inserted immediately, minimizing downtime.
Fuse Sift X1
This enclosed station handles part extraction and powder recovery through a glovebox system, improving cleanliness and efficiency.
Mix Kit
Recovered powder is automatically blended with fresh material using integrated scales to ensure the correct ratios and minimize waste.
Vacuum Conveyor
Material movement throughout the workflow is streamlined and largely automated.
Fuse Blast
Finished components are cleaned and polished in batches, producing smooth, professional-looking parts with minimal manual labor.
Together, these systems create a highly automated workflow that enables a single operator to manage production efficiently.
Who Should Consider the Formlabs Fuse X1?
The Fuse X1 is particularly attractive for:
- Existing Fuse 1+ users seeking greater throughput
- Service bureaus scaling production
- Engineering departments producing functional prototypes
- Manufacturers transitioning to digital production
- Companies that have been priced out of traditional industrial SLS systems
- Organizations seeking an alternative to expensive MJF platforms
A New Era for Industrial SLS Printing
The Formlabs Fuse X1 tackles six critical areas that matter most to manufacturers:
- Price
- Power requirements
- Floor space
- Build size
- Production speed
- Cost per part
Rather than simply enlarging the original Fuse platform, Formlabs has developed a complete industrial manufacturing solution that brings high-volume SLS production to a much broader audience.
For years, manufacturers wanted a larger Fuse. What they received is something even more significant: a machine capable of challenging some of the biggest names in industrial additive manufacturing while dramatically lowering the barriers to entry.
