This presentation will disclose and discuss a new technology platform for 3D printing composites that allows users to control and optimize fiber alignment at a microscopic level using magnetics. The system enables users to design fiber architectures to enhance and modulate strength, stiffness, HDT, wear resistance, and electrical material properties throughout a part as it is printed. Dr. Martin will share the history of the technology and biological phenomenon that inspired his team. The presentation will also focus on insights into how this technology can enable new application space for the industry. Fiber reinforced composites are a fast-growing segment of the AM industry though traditionally are limited to thermoplastic systems (FFF and SLS). Fortify’s technology is the first to employ reinforcement in a thermoset platform, and the first to allow fiber manipulation during printing. The discussion will include: (1) Methods for pre-treatment of fiber to make them magnetically responsive; (2) How existing technologies were integrated where possible to shorten development cycles and investment, and where novel hardware was required to achieve the team’s goals; (3) A workflow overview of how part load conditions are analyzed to generate fiber architectures; and (4) Future developments that can leverage fiber orientation to generate parts with directional thermal and electrical conductivity properties.
- Understand why and how controlling the orientation of fiber reinforcement is important in 3D printed composites
- Generate ideas about how fiber reinforcement could be leveraged for enhanced material properties that will be valuable to their products
- Be inspired to explore how components with variable material properties can be leveraged in your product designs
