The additivization of polymers with carbon fibers is a very common practice in plastic compounding. The 3NTR Carbon+ filament uses this technology to achieve better mechanical strength, maximum stiffness and thermal resistance. The Carbon+ filament was manufactured by 3NTR, an Italian company specialized in industrial 3D printers and filaments.

In 3D printing, carbon fiber is normally added in the form of shreds, powder or nanoparticles as a coating or inside of the polymer in order to improve the mechanical properties of a filament. The result is 3D printed parts that are stiffer, more dimensionally stable and lighter. In case of polymers such as nylon, adding carbon fiber makes PA easier to 3D print since it improves its adhesion and reduces warping. The Carbon+ filament can be used together with a soluble support filament such as the 3NTR SSU09.

Nylon (polyamide) is a synthetic polymer characterized by great resistance and durability. It is one of the most widely used materials in technical FDM 3D printing, both for the manufacturing of prototypes and functional end parts. Nylon was discovered in the form of highly elastic and resistant fibers, and it revolutionized the textile industry. Ever since scientists found a way to use nylon as a solid, it has gained a lot of popularity across industries for its durability, resistance and elasticity allowing for the manufacturing of objects capable of cushioning shocks and impacts between parts and supporting loads. Some applications of nylon include fishing lines, guitar strings, food products, zips and screws but also surgical products and industrial machinery.

There is no need for external adhesion improving products to be used with this filament. This is due to the fact that the 3NTR 3D printers, which this material is designed for, incorporate a carbon fiber base additivized with glass fiber to provide a highly adherent printing surface.
