Additive manufacturing is becoming a key technology in diverse industries like aerospace, automotive, consumer, medical and prosthetic sector, etc. Besides AM for metal application, the capabilities of polymer materials for industrial application improved enormously. New equipment is emerging that allows the usage of “functional” filaments like thermoplastics with a high strength-to-weight ratio and high-temperature range, conductive graphene materials, and others. The ability to increase the strength of polymers comparable to metal by embedding continuous fiber strings like carbon makes those techniques especially suitable for a wide range of application.
The presentation will expose attendees to experimental test results analyzing the performance of different additive manufactured functional polymers. It demonstrates a flex test series of specimens with embedded continuous carbon fiber reinforcement varying in amount and layout of the strings. The results will be compared to specimen made by dis-continuous carbon fiber composites. Design examples will be given using the unique properties of embedded continuous fiber for extremely lightweight, stiff and rigid functional parts. Furthermore, an additional study demonstrates the ability of commercially available 3D printers for the fabrication of multi-materials. Shown will be the experimental test results analyzing the mechanical properties and performance of several conductive filaments embedded in polymer testing boards. Finally, the potential and future trends of 3D printed functional parts with embedded low-cost electronically conductive structures are exposed.
