Safety First


Congratulations on your Onyx Pro purchase!

Please take a moment to review the following safety guidelines.

The following notes indicate potential safety hazards that should be recognized when operating a MarkForged Onyx Pro 3D Printer.

Before beginning use, the Onyx Pro must be plugged into a power outlet that is close to the printer and easily accessible. In case of an emergency, disconnect the Onyx Pro immediately from the power outlet.



The Onyx Pro generates high temperatures.

Tip: Always allow the Onyx Pro to cool down before opening the visor or lid, or before reaching inside the printer. Always take extra care when working near the print head. 



The Onyx Pro has many moving parts that could cause injury.

Tip: While the Onyx Pro is in operation never reach inside it, or open the visor or the lid.



There is risk of electric shock while the printer is in use.

Tip: Please consult with MarkForged or an Authorized Dealer for service. Do NOT use materials that have not been approved by MarkForged for use with the Onyx Pro. The Onyx Pro is designed to work only with MarkForged's proprietary materials and consumables.



The Onyx Pro melts thermoplastics and emits thermoplastic odors during printing.

Tip: Make sure to operate the Onyx Pro in a well-ventilated area.



The scraper provided with MarkForged printers is sharp and can cause injury if used incorrectly.

Tip: Always scrape away from yourself. Rest the bed in a vertical position, against a sturdy level surface when removing a part. Always use short, ramming motions to remove a part from the print bed. Always keep fingers or other body parts out of the path of the scraper when removing a part from the print bed. Keep the angle between the scraper and the print bed small while you are removing your part.
