Continuous Fiber Reinforced Composites in FDM 3D Printing

Standard FDM printers struggle with fiber reinforcement. I led a team to design a custom fiber‑coating system using Inventor for CAD, integrated it into a dual‑nozzle Qidi Tech X‑Pro, and validated results with Instron tensile testing.

• Designed custom “layering prism” in Inventor and integrated into dual‑nozzle Qidi Tech X‑Pro

• Printed 50+ composite specimens sliced in Qidi Print, achieving 20% higher tensile strength and 15% higher modulus

• Validated results with ASTM D638 tensile testing on Instron
