Composites are valued for being extremely strong and light and providing high strength to weight ratios and stiffness – but conventional composites manufacturing can be very expensive. Though 3D printing enables flexibility and lower production costs to build parts, fiber reinforcement is usually limited to very short-chopped fibers which only impart marginally improved strength and stiffness and 3D printing is usually limited by only being able to stack 2D slices of the final part.
MC 987901 / Continuous Fiber 3D Printing (CF3D™) from Continuous Composites allows you to discretely print long continuous fibers to accommodate loads in all three dimensions.
The process involves impregnating a dry fiber with a tailorable snap curing thermosetting photopolymer that is instantly cured upon deposition by a powerful UV light. This allows for bridging of large gaps without support to build complex parts on demand.
It can be used with structural fibers like carbon, glass, and aramid or functional fibers like optical fibers or copper.
The fully automated process allows for net shape printing of composites without the constraints of traditional manufacturing using affordable raw materials in limitless material combinations that can be tailored for mechanical properties, heat transfer and environmental durability.
Applications of this technology include aerospace, automotive, marine, defense, sporting goods, energy, and construction.
