Reinforce your Parts

Markforged’s fiber technology revolutionizes 3D printing by infusing high-strength fibers like carbon, fiberglass, and Kevlar® into parts, significantly boosting their durability and performance. This advanced approach is ideal for high-demand industries, offering customized, robust solutions beyond traditional manufacturing capabilities. Embrace the strength and innovation of reinforced 3D printing with Markforged.

Continuous Fiber Options

The ability to choose different types of fibers allows for customization of material properties based on specific application needs, such as flexibility, impact resistance, or thermal stability.

Fiber Reinforcements Print My Parts Offers:

  • Carbon Fiber: Known for its high stiffness, strength-to-weight ratio, and low thermal expansion. Ideal for applications requiring the utmost in strength and rigidity.
  • Fiberglass: Offers a more cost-effective alternative to carbon fiber while still providing excellent strength and stiffness.
  • Kevlar: Renowned for its impact resistance and durability, Kevlar is ideal for parts that need to endure repetitive or sudden loads.
  • HSHT Fiberglass: Designed for high-temperature applications, it maintains its mechanical properties even at elevated temperatures.

How does Continuous Fiber Reinforcing work?


Markforged’s Continuous Fiber Reinforcement (CFR) technology enhances 3D printed parts by integrating continuous fibers like carbon fiber, fiberglass, or Kevlar into a base thermoplastic material using a dual extrusion system. This process allows for targeted reinforcement in specific areas of a part, significantly increasing strength and stiffness.
