New 3D printing technology for continuous carbon fiber

A team of Kun (Kelvin) Fu, an assistant professor at the University of Delaware, has developed a 3D printing technology that enables low-cost, flexible production of items made of fiber-reinforced polymer composites using continuous carbon fibers and thermosetting polymers.

Localized in-plane thermal assisted (LITA) 3D printing allows the user to control the thickness and degree of curing of liquid polymer that solidifies into the desired shape. LITA 3D printing could provide many industries with a rapid, energy-efficient method to make composite components in a variety of shapes using a variety of combinations of polymers and fibers.
