3D Printing Composite Materials Guide

Introduction to Composites

Composite materials for 3D printing combine a base polymer with reinforcing fibers. The result is dramatically improved strength and stiffness.

Carbon Fiber Reinforced

Offers the highest stiffness-to-weight ratio. CFR-PLA and CFR-Nylon are common. Parts are 2-3x stiffer than unreinforced equivalents.

Glass Fiber Reinforced

More cost-effective than carbon fiber with good strength improvement. Widely used in Nylon and Polypropylene grades.

Summary: Composite 3D printing materials dramatically expand the mechanical capabilities of additive manufacturing.
