The company Anisoprint, a manufacturer of 3D printers for printing composites with continuous fibers, has developed a Composite Basalt Fiber (CBF).
In 2016 Anisoprint was named the winner of the competition for the best technology for the industry, and now the company presents its new development.
Traditionally, plastics were reinforced with chopped fiber (fiber) or applied fiber and polymer layers, and this created problems with strength. The key advantage of the combined co-extrusion method is the printing with plastic reinforced with continuous fiber.
Anisoprinting — technology of co-extrusion of a continuous composite fiber. Co-extrusion (joint application of two materials) allows using different thermoplastic polymers as a binder and reinforcing them with continuous composite fibers. In this way, the direction, volume fraction and density of the fibers can be varied.
In the printers “Anisoprint” pre-impregnated filament is given simultaneously with the polymer in a certain direction. By changing the volume content of fibers in specific places, you can increase the rigidity of the product in the desired contours or points of the structure. And the control of the printing direction allows to form accurate and durable technological holes, which eliminates the need to make them in the finished product, violating the integrity of the material.
Solutions based on two matrices – thermosetting and thermoplastic-are available for various applications of the final product, which provides excellent adhesion and low porosity.
Products printed using basalt fiber technology anisoprinting, superior to the combination of physical and mechanical characteristics of metal and plastic, being up to fifteen times stronger than non-reinforced polymers, five times lighter than steel, one and a half times stronger and lighter than aluminum. The use of CBF reduces production costs, and printed parts are obtained several times cheaper than analogues from other materials.
A special property of basalt is radio transparency. Printed from basalt fiber parts do not have a significant impact on the amplitude and frequency of electromagnetic waves passing through them. Composite basalt fiber is an excellent material for radio-transparent and insulating elements.
It should also be mentioned that the use of continuous basalt fiber can significantly reduce the cost of the final product.
Currently, the company “Anisoprint ” offers two reinforcing materials-composite carbon fiber Composite Carbon Fiber (CCF) and composite basalt fiber Composite Basalt Fiber (CBF). In the printing process, the reinforcing fiber is combined with plastic (PET-G, ABS, PLA, polycarbonate, nylon, etc.). The output is strong and lightweight parts with the required chemical, thermal and surface properties.
Composite basalt fiber can be ordered together with 3D printers Anisoprint Composer on the official website of the manufacturer.
