Desktop Metal Fiber

Industrial-grade composites. With continuous fiber tapes for unrivaled part strength*.

An end-to-end solution

Fiber™ is the only composite 3D printer to use micro automated fiber placement (μAFP)—unlocking unparalleled composite part strength for a desktop printer. Featuring closed loop heat control, the μAFP head constructs a high-density, continuous fiber reinforcement while the FFF printhead enables a high-resolution exterior shell. Utilizing tapes made with 12k continuous fiber tows, up to 60% fiber volume fraction, and exceptional resin impregnation, Fiber™ is able to achieve continuous fiber reinforcement with less than 1% porosity—delivering parts with 2x the strength of steel at 1/2 the weight of aluminum.

How it Works

Fiber™ features two printheads—one dedicated to deposition of continuous fiber prepreg tape (μAFP), one dedicated to extrusion of a chopped fiber filament.

1. Prep

Generate geometry, review loading conditions, and identify areas for reinforcement.

2. Reinforce

Selectively reinforce with continuous fiber μAFP tape along critical load paths

3. Print

The Fiber™ printer utilizes a dual-deposition print method to build parts layer-by-layer in both chopped fiber filament and continuous fiber µAFP tape.

4. Part Anatomy

Parts printed on Fiber™ feature a chopped fiber shell and solid continuous fiber reinforcements.

Fiber™ offers users exceptional part quality and a wide range of engineering-grade materials—all on a user-friendly, desktop printer.

Strong parts

Fiber™ combines the exceptional performance of continuous fiber with the ease of FFF printing to produce high-performance parts that are stronger than steel, lighter than aluminum, and can operate continuously in the toughest environments up to 250 ºC.

Continuous fiber reinforcement

Continuous fiber tape is applied along critical load paths in a process called Micro Automated Fiber Placement (µAFP). Layers of highly loaded continuous fiber tape are laminated to build fully-dense, reinforced sections two times stronger than steel at <1/5 the weight (up to 2,500 MPa tensile strength and <1.5 g/cc).

Low porosity

Utilizing tapes made with 12k continuous fiber tows, up to 60 porosity.

Multi-directional reinforcement

Layers of continuous fiber are deposited via µAFP. Users can automatically optimize fiber orientation for maximum coverage, or enable Expert Mode to tailor orientation for specific loading conditions.

Widest range of materials

Fiber™ prints with two printheads—one dedicated to continuous fiber tape; one dedicated to chopped fiber-reinforced filament. Designed for versatility, the printer supports a wide range of fiber-reinforced composites to enable a broad set of applications from consumer electronics to automotive.

PEKK + Continuous Carbon Fiber

PEKK is characterized by its high tensile and compression strength, resistance to chemical abrasion, and ability to withstand high temperatures (above 250­­ °C). When reinforced with carbon fiber, resulting parts are exceptionally durable and well-suited for extreme environments.

PEEK + Continuous Carbon Fiber

PEEK is characterized by exceptional mechanical properties, high resistance to surface abrasion, and is inherently flame retardant. When combined with continuous carbon fiber, the resulting composite is strong, stiff, and boasts a high fatigue level—making it great for high-wear manufacturing jigs and fixtures.

Nylon (PA6) + Continuous Carbon Fiber

Our PA6 nylon with carbon fiber reinforcement is safe for operations where ESD compliance is required. With a tensile strength 30x stronger than ABS, PA6 + CF is an excellent material for end-of-arm tooling, including those used in electronics manufacturing.

Nylon (PA6) + Continuous Fiberglass

Fiberglass-reinforced nylon is a low-cost material which renders lightweight, high-strength and corrosion-resistant parts—making it a great match for sporting goods applications where parts are exposed to the elements and have a low target cost per part.

Accessible to all

With a wide range of materials, easy-to-use platform, and affordable subscription tiers, Fiber™ offers high-quality composite printing at a price point every engineer and designer can access.

Easy to use

In a matter of minutes, users can begin printing industrial-grade composites from the comfort of their desktop. Entry-level settings and opt-in advanced controls allow every engineer to produce high-quality composite parts at the press of a button.


Starting at just $3,495/yr—¼ the cost of other industrial continuous fiber composite printers***—and boasting superior materials and a large build envelope, Fiber™ offers unrivaled utility at just a fraction of the cost. With Fiber™, engineers no longer have to trade between high quality, speed, and affordability.
