Fiberglass is a cost-effective industrial composite used for composite reinforcement 3D print applications on Markforged systems. As an entry-level continuous fiber, it provides strong, lightweight reinforcement for Fiberglass 3D printing applications, supporting practical structural fiber manufacturing across engineering and production environments.
Fiberglass is Markforged’s entry-level cost-effective industrial composite for continuous fiber reinforcement. It produces parts up to 10× stronger than ABS when used as a composite reinforcement 3D print material within Onyx® or other composite base materials. This material is a practical choice for teams that need strong, lightweight components without the cost of carbon fiber. As a result, it supports a wide range of Fiberglass 3D printing applications across engineering and production environments.
Designed for structural fiber manufacturing, Fiberglass delivers predictable strength and stiffness when embedded as continuous strands within printed parts. Its reinforcement improves load-bearing capability, impact resistance, and deformation control. The 3D printing material is compatible with the FX20™, X7™, and Mark Two™. As a result, it fits into existing composite workflows, enabling engineers to print structural components that perform well under mechanical stress.
Fiberglass provides an accessible alternative to carbon fiber with significant mechanical benefits. For example, it enhances part strength without increasing weight and supports fiberglass 3D printing applications such as brackets, fixtures, tooling, and functional prototypes. Fiberglass offers strong, affordable reinforcement for industrial teams needing efficient, reliable composite reinforcement 3D print parts.
