Starts Great And Keeps Getting Better

No other desktop 3D printer gives you the benefits of ever-improving functionality. Whether it's a hardware step up to the next level printer for stronger parts or more advanced capabilities in software, the same printer you purchased simply keeps improving over time. Each printer in our line, starting with the Onyx One can be upgraded to the next step up or to our industrial lineup.

Upgrade your Onyx One to Continuous Fiber

When you need stronger parts, upgrade your Onyx One to an Onyx Pro by adding continuous fiber printing capability. This quick step happens at your desktop and will let you print parts with 5X the strength of Onyx alone.
