NAME Additive manufacturing of continuous fiber composites

MOST OUTSTANDING EQUIPMENT AND COMPONENTS

• 1 JCR 1000 (1000 mm × 600 mm × 600 mm) FFF

  Manufacture of prototype moulds (Infusion, RTM...) and tools for composites. The versatility of the JCR 1000 (Sicnova) is based on its large printing volume (1000 mm x 600 mm x 600 mm) and the possibility of printing any type of plastic, since it is possible to modify/program all printing parameters. The production of moulds and tools using 3D printing considerably reduces, compared to conventional machining techniques, both development times and costs.

• DMP-Precision Fluid Deposition

  Printing of electronics (embedded systems) in composites. The third available technology, ink printing, allows electronic circuitry to be printed, so new functions can be integrated into the plastic/composite parts. In the case of co-printing with continuous fibre composites, embedded systems can be integrated to monitor the state of the component (Structural Health Monitoring, SHM) and/or communications (RFID, IIoT). In the case of moulds and tools, the co-printing of electronics will allow intelligent systems to be developed with a higher level of connectivity.

• MarkTwo (1000 mm × 600 mm × 600 mm) FFF

  Printing of continuous fibre composites. The MarkTwo (Markforged) allows you to work with continuous fibre composites (carbon, glass, Kevlar...) with high stiffness (40 GPa) and strength (700 MPa). The printing volume is 320 mm x 132 mm x 154 mm. Structural optimization based on simulations using finite elements method as well as topological optimization strategies, are the ideal complement for the development of new advanced products. In addition, non-conventional orientation (steered-fibers) can be obtained, ideal for inserts or complex geometry parts. There is also the possibility of testing new filaments for formulation optimization in order to manufacture and characterize their mechanical properties. Among the components that can be developed stand out the inserts that, when printing thermoplastic matrix composites, can be integrated into the plastic injection moulding process (over-injection).
