Xenia launches PA12 carbon fiber filament with tough matrix for FFF applications

The Italian materials specialist Xenia is expanding its 3DF portfolio with XECARB PA12-CF-ST, a carbon-fiber-reinforced filament for FFF/FDM printing that will be showcased at Formnext 2025. The base is a polyamide 12 matrix with low water absorption and high abrasion resistance; a 15 percent short-fiber content is intended to ensure stiffness, dimensional stability, and a favorable mass-to-strength ratio. The manufacturer combines this with a “Super Tough” modification of the polymer phase that increases elongation at break and impact toughness without undermining the lightweight advantage. With a heat deflection temperature of 150 °C, the material targets functional parts that must remain dimensionally stable under temperature and load.

In the context of applications close to additive series production, PA12-CF-ST addresses typical weaknesses of fiber-filled filaments: brittle failure under impact loads and creep at elevated temperatures. Xenia relies on a toughness-modified matrix that improves load transfer between fiber and polymer, thereby better buffering cyclic stresses. For practical use, the company cites areas such as automotive, aerospace, and industrial equipment, where structural load-bearing capacity, fatigue resistance, and long-term durability are required. PA12’s low water absorption reduces moisture-induced dimensional changes in operation and simplifies drying management prior to printing.

With the new filament, Xenia expands a program that already includes biopolyamides, elastomeric lightweight materials, and chemically resistant formulations. These include a PA11-CF material based on bio-based feedstock for applications with very low density, a PEBA-based filament with high flexibility and energy absorption, a conductive PVDF-CF material with increased chemical resistance, and a PETG-CF derived from recycling streams for application-oriented stability with a lower environmental footprint.

Xenia will present PA12-CF-ST at booth F98 in hall 12.1 and will offer technical discussions on printing parameter selection, part design, and post-processing. For users who want to additively manufacture compact, robust functional parts, the combination of a tough matrix and moderate fiber content is an interesting approach for reproducible FFF processes.
