Xenia Launches 15% Carbon Fiber PEBA Filament
Xenia Materials has introduced XECARB PEBA-CF, a carbon fiber-reinforced PEBA filament unveiled at Formnext 2026.
Updated on Nov. 5, 2026 in Materials Science
Xenia Materials launched XECARB PEBA-CF, an FFF/FDM filament built on a PEBA matrix and reinforced with 15% carbon fiber, at Formnext 2026. The product is positioned to add stiffness to the typically flexible PEBA material while retaining its elastomeric toughness.
Why it matters
PEBA's flexibility can be a limitation when a printed part must hold its shape under load, and the added carbon fiber targets that gap for additive manufacturing users. The launch extends Xenia's 3DF Materials portfolio, which now includes seven filaments.
XECARB PEBA-CF has a density of 1.08 g/cm³ and a heat deflection temperature of 105°C, with 15% carbon fiber reinforcement. Xenia has not published independent test data in the material's specification sheet, leaving its load performance unverified.
The players
Xenia Materials
Xenia Materials is a compounding company headquartered in Vicenza, Italy, that develops engineered filaments for additive manufacturing under its 3DF Materials line.
The details
XECARB PEBA-CF is designed for FFF/FDM printing, where the carbon fiber stiffens the PEBA matrix while the elastomeric phase handles toughness and elastic response. The filament was introduced alongside Xenia's broader lineup, which includes XELIGHT PEBA, an unreinforced ultra-lightweight PEBA option.
Timeline
Earlier in 2026: Xenia supplied carbon fiber-reinforced polycarbonate tooling for the O.L.I.V.I.A. drone.
April 2026: Xenia launched XECARB PPA-CF, a 20% carbon fiber PPA grade.
2026 (Formnext): XECARB PEBA-CF was launched at Formnext 2026.
The Big Picture
Xenia's carbon fiber reinforcement strategy, already applied to its PA11, PETG and PPA filaments, now extends to the flexible PEBA elastomer. The move addresses the long-standing trade-off in printable elastomers between flexibility and dimensional stiffness.
Engineers designing printed parts that must flex yet hold their geometry under load may find a reinforced PEBA option useful for prototypes and functional components. Practical adoption will depend on printer compatibility and the material's real-world mechanical performance, which the launch materials do not fully quantify.
The takeaway
Reinforcing a flexible polymer with carbon fiber is a practical way to widen the range of parts that can be printed from elastomers. Buyers should request mechanical test data before relying on the material for load-bearing applications.
