AME-3D, a UK-based additive manufacturing service provider specializing in rapid prototyping and low-volume production, has expanded its materials offering through the introduction of Windform composite materials developed by CRP Technology. The addition allows UK designers and engineers to access high-performance selective laser sintering (SLS) parts for advanced industrial applications where strength, lightweight performance, and thermal stability are critical.
CRP Technology develops high-performance composite materials used in professional additive manufacturing. Its Windform range is recognized for combining mechanical strength, thermal stability, and low weight in parts designed for functional use. The materials are available in several fiber-reinforced grades, including carbon- and glass-filled versions, as well as flame-retardant formulations suited to demanding operating conditions.
Windform composites deliver a combination of rigidity and durability that surpasses standard polymers. Depending on the selected grade, they can be electrically insulating or slightly conductive. Several variants meet UL94 V-0 certification for flammability resistance, comply with NASA and European Space Agency outgassing requirements, and satisfy the FAR 25.853 flammability standard. These properties make them suitable for producing components that must retain structural integrity under environmental or mechanical stress.
Jamie Corden, Sales and Marketing Director at the Sheffield-based company, said the addition of Windform composites expands its support for UK engineers. “Our goal has always been to make advanced manufacturing accessible to UK designers and engineers,” said Corden. “The addition of Windform composites means we can now support projects where strength, lightweight performance, and environmental resistance are critical. It’s a great step forward for our customers who need functional parts that perform beyond traditional polymers.”
The additive manufacturing service provider has integrated these composites into its SLS production capabilities while continuing to offer design support, material selection, and finishing services. By supplying materials with enhanced mechanical and thermal performance, the UK firm can produce functional parts capable of meeting operational requirements across advanced industrial sectors.
Advances in Composite Materials for Additive Manufacturing
A review published in Nature Communications by researchers at the University of Colorado and Georgia Tech examined how additive manufacturing and computational design are accelerating the development of next-generation composite materials. The study detailed how 3D printing methods incorporating nanoparticles, short fibers, and continuous fibers enable precise control of structure, fiber orientation, and material distribution, producing components with tailored mechanical, thermal, and electrical performance. These approaches eliminate the need for molds and lower production costs while supporting multifunctional designs across aerospace, energy, robotics, and biomedical sectors. Techniques such as fused filament fabrication, digital light processing, and direct ink writing have introduced new ways to print reinforced polymers, while continuous fiber systems have achieved properties comparable to aerospace-grade laminates.
In related research, engineers at the University of Toronto have developed a 3D printed metal composite that combines high strength and low weight even at elevated temperatures. Using selective laser melting, the team produced a titanium-reinforced aluminum matrix structured like reinforced concrete, where the titanium acts as the load-bearing framework. The resulting material achieved yield strengths up to 700 megapascals at room temperature and maintained 300–400 megapascals at 500 °C—performance comparable to medium-grade steels at roughly one-third of the weight. This “rebar-inspired” architecture demonstrates how additive manufacturing can create novel material systems that balance strength, heat resistance, and weight efficiency for aerospace and other high-performance industries.
