The Anisoprint company has developed a dedicated technology of printing with continuous fiber reinforced materials which makes use of anisotropic properties of composite fibers. The technology is based on the FFF process and got the name CFC (Composite Fiber Co-extrusion). 3D printers feature a dual extrusion system where one extruder is used for printing with standard plastic filaments, and the other, composite extruder has been specifically designed to print with fiber reinforced composites. The reinforcing fiber and the compatible plastic filament, used as matrix, are fed into the composite extruder which is heated up to the temperature of plastic processing. Running through the extruder, the fiber gets covered with molten polymer and the reinforced material is extruded to build a part.

The Anisoprint Composite Basalt Fiber is a tow of 0.28 mm in diameter which consists of thousands of ultrathin basalt monofilaments. The fiber is pre-impregnated with a polymer composition for perfect adhesion with the plastic matrix. You can choose among most common polymers, such as PLA, ABS, PC, PA, or PETG, with printing temperatures up to 250 °C to use as a matrix; the manufacturer recommends using PLA or PETG.

Basalt can be considered a more affordable alternative to carbon fiber when a slightly less part strength is not a crucial point. Another advantage of basalt fiber, unlike other high-strength materials, is its radio transparency which allows building strong parts that do not interfere with the frequencies of electromagnetic waves passing through.

The use of continuous basalt fiber for reinforced perimeters and internal lattice structures allows for fabrication of strong, durable yet lightweight parts at affordable price. Building lattice structures provides time and material savings without compromising on quality. The technology finds its application in such fields as automotive, aerospace, and healthcare industries, spare parts and consumer goods production, as well as in manufacturing of radio transparent models.
