The X7 prints Composite Base filaments like a conventional FFF thermoplastic. Bases can be printed alone or reinforced with any of our composite reinforcement materials, including Carbon Fiber. Composite base materials are plastic based and can contain some volume of chopped carbon fiber.
Only Markforged printers can lay down Continuous Fiber Reinforcement inside of parts through a second nozzle. These fibers cannot be printed alone and are used to reinforce parts printed out of a composite base material like Onyx.
