Reinforce 3D, a Spanish start-up, has developed a technique to insert continuous carbon firbe strands (4-8mm in diameter) into 3D printed components. This exciting development allows fibres and resins to be inserted into cavities after components are printed (in plastic, ceramics, or other materials), overcoming the problems associated with placing fibres and printing at the same time.
Lightweight parts, with complex and curved shapes, can be optimized for strength. By using continuous carbon fiber as a reinforcing agent often reduces the amount of material needed for the external component, delivering cost and environmental benefits. Multiple components can be joined using this system delivering superior results when compared with traditional bonding techniques.
The company claims to have developed prototypes for projects for Airbus, Spanish marine defense manufacturer, Navantia (Madrid, Spain) and tooling for the Spanish automotive manufacturer SEAT. Future planned applications include bicycle frame components, elite sports shoes, interior aircraft brackets, spacecraft and antenna components, automotive brakes and components for race vehicles, fixtures and robotic arm components.
