Boost your part strength without the weight using Fiberglass Continuous Filament Fabrication (CFF)—an affordable, high-strength composite reinforcement material for Markforged 3D printers. Ideal for everyday load-bearing applications, this spool allows you to print functional prototypes and end-use parts that are up to 10x stronger than plastic alone.
Available in 50cc (Product Code: FG-AB-50) and 150cc (Product Code: F-FG-0003) sizes, Fiberglass is the perfect entry-level fiber for cost-effective, reinforced 3D printing with minimal compromise on print speed or ease of use.
Key Features:
Available in 50cc and 150cc spool sizes
Print parts with up to 10x the strength of standard thermoplastics
Most affordable CFF material in the Markforged ecosystem
Ideal for jigs, fixtures, tooling, and functional prototypes
Seamless compatibility with Markforged composite printers
Easy handling with minimal fiber fraying or downtime
Why Choose Fiberglass CFF?
