What's New With The Onyx Pro?

  • 40% faster fiber printing process
  • Reinforce features 15 times smaller than before
  • Increased print reliability with additional sensors in the printhead
  • A host of new in software, hardware, and materials improvements

Have you ever 3D printed a part that wasn’t strong enough?
The revolutionary Onyx Pro prints with the strength of aluminum. Now you can have the dependability of CNC parts with the flexibility of 3D printing.

How It Works
The Onyx Pro has two print heads. One builds Nylon parts. The other is a revolutionary, new composite print head to reinforce those parts with continuous fiber.

3D print parts you used to CNC
The unique composite reinforcement technology of the Onyx Pro lets you 3D print parts stiffer and stronger than ever before. Save time and energy by 3D printing parts instead of milling them.

High-Strength Printing
By reinforcing your parts with composite fiber while 3D printing them, The Onyx Pro achieves unparalleled strength, stiffness and durability in its printed parts. Automatically strong, our software automatically reinforces your parts with fiber to maximize strength and stiffness.


Higher strength-to-weight than 6061 Aluminum
The Onyx Pro prints outer contours and curves in engineering nylon and fills each part with close-packed reinforcement in continuous carbon fiber, Kevlar or fiberglass. We validate our material performance with exhaustive cycle and environmental testing to ensure that your parts retain their strength over extended use.

Precision Design
The Onyx Pro print bed clicks into place with 10 micron accuracy – allowing you to pause a print, remove the bed, add components, click the bed back in and then continue the print in the exact same position.

Range of Materials
The Onyx Professional prints Carbon Fiber, Onyx, Fiberglass, Kevlar and Nylon. This allows you to take advantage of the non-scratch surface of Nylon and the strength of Carbon Fiber in the same part.

  • Nylon is an incredibly strong, durable, and versatile 3D printing material. Flexible when thin, but with very high inter-layer adhesion, nylon lends itself well to things like living hinges and other functional parts. Its low friction coefficient and high melting temperature make it an excellent choice for things like printed gears.
  • Onyx is engineered for engineers. Perfectly suited for applications that demand a high-performance material. The parts you design are the parts you get. Added micro-carbon reinforcing fiber makes for more stable parts, driving increased dimensional stability and print success rate.
  • Carbon Fiber has the highest strength to weight as well as the highest thermal conductivity. Perfect for applications requiring the greatest possible stiffness and strength.
  • Fiberglass is the most cost-effective material. It's a strong as Carbon Fiber, but 40% as stiff, and 2X the weight. Suited to everyday applications where you need strong parts.
  • Kevlar® has the best abrasion resistance and is our most flexible material. For when you need parts that are durable and resistant to impact. Kevlar is only available on the Mark Two Professoinal model, and Enterprise edition.

We built our own 3D printing software that comes with the Onyx Pro. Printing a part to be flexible or strong is easy and intuitive.

Powerful Software
Every Onyx Pro comes with Eiger, our browser based 3D printing software. Eiger runs on any computer and is designed to be easy to use. So you can get printing quickly.

Best Results
Nylon must be dry, as it is very hygroscopic. That means it readily absorbs water from the air. Nylon can absorb more than 10% of its weight in water in less than 24 hours. Successful 3D printing with nylon requires dry filament. When you print with nylon that isn’t dry, the water in the filament explodes causing air bubbles during printing that prevents good layer adhesion and greatly weakens the part. It also ruins the surface finish. Dry nylon prints buttery smooth and has a finish sheen. To dry nylon, place it in an oven at 180°-200°F for up to 6-8 hours. After drying, store in an airtight container, preferably with desiccant.
