Integrated Robotic 3D Printing System for (Fiber Reinforced) Polymer Parts

Description:

Reference #: 01157

The University of South Carolina is offering licensing opportunities for an integrated 3D printing system to multi-axial composite parts.

Invention Description:

The subject invention is a 3D printer that can print thin composite parts with continuous fibers in multiple directions. The printer allows the production of thin-walled, carbon fiber-reinforced parts without the use of positive or negative molds. It combines the advantages of traditional 3D printing with plastics with the strength and stiffness of composite parts produced with methods such as vacuum injection.

Potential Applications:

  • 3D printing ready-for-use, thin-walled aircraft ducts
  • Future 3D printing of high performance, industrial parts

Advantages and Benefits:

The invention allows 3D printing of multi-axial composite parts that are lightweight and high strength and stiffness for the first time.

Background:

Unreinforced polymer 3D printed parts do not comply with stiffness and strength requirements for aircraft parts. This subject invention uses continuous fiber reinforcement to meet those requirements. It allows the printing of fibers in different directions in the plane perpendicular to the hotbed. This enables the creation of real composite parts that cannot be produced with traditional 3D printers based on printing layer by layer, and therefore, allowing only fibers in the cross-sectional plane.
