Additive Technology: FFF

Fused Filament Fabrication

FFF is our most popular print process. It’s mainly used for high strength parts, functional prototypes, manufacturing fixtures and small batch production.

What Is FFF Technology?


FFF is similar to FDM technology, material is extruded and parts are created layer by layer, but it also allows us to add a continuous fiber reinforcement to the inside of a part.


Incredibly strong, composite parts, with high detail, smooth surface finish and dimensionally stable materials.


Support marks may be visible, limited base materials and colors available.

Advantages of FFF

Industrial Strength

FFF uses a material called Onyx, it’s a Nylon based material with chopped carbon fiber. Onyx is high strength with excellent heat resistance, surface finish, and chemical resistance.

Complex Geometries

Print geometries not possible or too costly for CNC machining. This allows you to increase efficiency within your designs without increasing cost.

Quick Turnaround

Our fleet of FFF machines are ready to print your parts. We can reduce production lead times from weeks or months to just a few days.

Composite 3D Printing

We can add continuous fiber reinforcement to the internal structure of your parts, this allows us to print composite parts that achieve unparalleled strength, stiffness and durability.

Exceptional Quality

Go from CAD to beautiful quality, strong, end-use parts in days. Onyx has a shimmery surface that hides layer lines and produces exceptional parts.

Large Build Volume

We can print Onyx on it’s own or reinforced with continuous fiber and produce large build volumes up to 330 x 270 x 200 mm.

Performance Parts On-Demand

We print composite parts using a continuous fiber reinforcement that provides a better strength-to-weight ratio than machined aluminum.

Below is a list of materials we offer for Fused Filament Fabrication.



Base Material

Onyx is 40% stiffer than ABS and provides the foundation for composite printing. It can be printed on its own or reinforced with any of our continuous fibers.



Fiber Reinforcement

Carbon Fiber is our stiffest and strongest fiber. It has superior stiffness and minimal deflection, making it strong enough to replace aluminum at half the weight.



Fiber Reinforcement

Use fiberglass reinforcement to print parts that need to be stronger than our standard plastic materials, such as ABS or HIPS, but at the most affordable price possible.



Base Material

Nylon is a non-abrasive material that can be stiffened with any of our continuous fiber options. It’s a versatile material both with and without fiber reinforcement.



Fiber Reinforcement

Kevlar has low density and high durability, which makes it great for applications that involve a lot of motion or require a fixture to interface with production parts.



Fiber Reinforcement

With superior heat resistance and similar flex strength to carbon fiber, HSHT fiberglass is ideal for applications requiring high heat, elasticity and impact resistance.
