# Moi Composites’ Short Fiber Manufacturing transforms industrial composite AM

One of the biggest highlights of Formnext 2025 was undoubtedly walking into Hall 12.1 and seeing [Moi Composites'](https://www.voxelmatters.directory/company/moi/) impressive booth, where an abundance of large-scale industrial and design components (including massive Easter Island statues) surrounded the company’s shining star: the new [Hybrid Fabrication Platform (HFP)](https://www.voxelmatters.com/moi-composites-unveils-the-hfp-series/). Visitors won’t have missed the system’s massive profile and bright orange window giving onto a live robotic printing session. 

Not only does the HFP system look impressive, however: it actually represents a major advancement in large-format composite additive manufacturing. The new system is based on Moi Composite’s new Short Fiber Manufacturing (SFM) process, a cold-process technology that uses UV-activated deposition to print vinyl ester resins with a high level (up to 50%) of short-fiber content.

The robot can also be optionally expanded with a +2-axis table. At the end of the robotic arm is Moi Composites’ proprietary S18 toolhead, which is capable of depositing printing bead widths ranging from 4 to 8 mm and enables the high-throughput deposition of short-fiber-reinforced thermoset composites. These short fibers are fed directly into the toolhead from an external reservoir. 

Notably, the S18 end-effector is also available as a standalone product that users can buy to upgrade existing robotic systems. Adding to SFM’s capabilities, Moi Composite’s HFP solution also integrates precision milling capabilities, eliminating the need for external post-processing equipment and enabling the production of precision, industrial-quality composite parts. 

The new SFM additive manufacturing process not only introduces the ability to print vinyl ester resins with short-fiber reinforcement of up to 50%, it also unlocks continuous production and rapid printing rates of up to up to 300 mm/s. This is thanks in part to the rapid-curing properties of vinyl ester resins. 

“The combination of material and fast curing kinetics enables overprinting, allowing operators to implement different slicing strategies on the same part while taking full advantage of geometric and design freedom with extreme overhangs,” elaborates Giovanni Minari, Head of Materials Engineering Department at Moi Composites. 

Moreover, the cured thermoset composites have a beneficial combination of properties, including high strength, good heat resistance, and excellent machinability. This last property is key for the hybrid HFP system, which leverages subtractive post-processing to achieve tight tolerances and create ultra-smooth composite parts that are primed for additional finishing steps like painting.

“The near-net shape produced during printing minimizes material removal during finishing, making high-quality surface finishing an inherent feature of the process,” Minari adds. “This capability is ideal for both functional components and tooling applications, such as molds or jigs.”

Moi showcased a variety of applications for its innovative composite AM technology at Formnext 2025, including a part that underwent public flame tests. As the company explains, a key performance benefit of vinyl ester composites used in its SFM process is that they are highly fire resistant and chemically stable. Those who witnessed the fire tests in person would have seen a Moi team member expose a 3D printed part to an oxy-fuel flame (with a temperature around 1,500 °C) for more than one minute. The part, an 8 mm printed tile, exhibited no ignition, no dripping, and self-extinguished once the flame was removed. Moreover, the temperature of the tile’s rear face only reached 156 °C, demonstrating a high level of thermal stability suitable for high-performance tooling applications and extreme environments.

Other demonstrator parts showcased the cold-curing technology’s ability to produce complex geometries that would be impossible under thermal constraints. Visitors will have also witnessed the speed at which the HFP system prints, building large-scale parts at rapid rates of up to 300 mm/s even in non planar deposition paths.

“By building an ecosystem around the intrinsic advantages of a cold-process approach, MOI Composites provides manufacturers with a practical and scalable solution for industrial additive production,”  Minari said. “The technology expands the role of composites in AM, delivering industrial-grade durability, chemical resistance, and fire performance while dramatically reducing production times. This enables companies to produce functional parts and advanced tooling within hours, streamline operations, and unlock new design and application possibilities.”

Indeed, Moi Composites’ new SFM-driven HFP solution gives manufacturers all the tools they need to produce large-scale composite structures—including high-performance molds, tooling, and fire-resistance functional parts—in a rapid, sustainable, and agile way.
