Problem
3D printed parts often lack the mechanical strength and lightweighting performance required for demanding applications across various industries. Traditional additive manufacturing processes may not adequately address the need for stronger, more durable materials with optimized fiber placement.
Solution
Reinforce3D enhances the performance of 3D printed parts through its patented Continuous Fiber Injection Process (CFIP). CFIP is a post-process technology that reinforces parts with continuous fibers, such as carbon fibers, by injecting them along with liquid resin into tubular cavities within the printed part. The resin, once solidified, acts as a mechanical interface between the fibers and the part, improving mechanical properties and enabling lightweighting. This approach allows for fiber placement in complex trajectories, reinforcement of parts made from various AM technologies and materials (including plastics, metals, and ceramics), integral joining of different parts with fiber continuity, and efficient manufacturing of large, multi-material structures.
Target Audience
The primary target audience includes companies in aerospace, automotive, sporting goods, health, and construction industries seeking to enhance the mechanical performance and reduce the weight of their 3D printed parts.
