Markforged 3D printers are the next level in professional quality 3D printing. While most 3D printers use a plastic filament material, Markforged machines use proprietary materials such as Onyx - a micro-carbon reinforced nylon that produces strong and heat resistant parts. Markforged printers include the Onyx One, Onyx Pro, Mark Two, Mark X, and the Metal X which creates models out of stainless steel or aluminum for immediate use. Other material options include Kevlar, Carbon Fiber, Fiberglass, and Nylon, all of which are ready to 3D print engineering grade products in your workshop or home today. The Markforged family of printers is also an upgradeable platform, meaning your investment in an Onyx One printer can be upgraded to an Onyx Pro and Markforged even has a trade in program wherein users can move from an Only Pro machine into the Mark X or Metal X setup. Markforged is dedicated to producing the highest quality, professional production parts and their robust and reliable 3D printers produce impressive results.
