Markforged Onyx

Markforged Onyx is a specialized 3D printing material recognized as one of the industry's most widely used engineering-grade filaments. It is a micro-carbon fiber filled nylon, specifically formulated to provide superior thermal properties, surface finish, and chemical resistance compared to standard plastic filaments. Originally developed to work with Markforged's proprietary Continuous Fiber Reinforcement (CFR) technology, Onyx serves as a high-strength base material for industrial parts and tooling.

The product is manufactured in the United States, which aligns with the company's vertically integrated approach to additive manufacturing. By controlling both the hardware and the material science behind their filaments, Markforged ensures consistent mechanical properties across their range of industrial 3D printers. This material has played a critical role in moving 3D printing from rapid prototyping into end-use part production.

Markforged was founded by Greg Mark in Massachusetts, USA. The company has since grown into a publicly traded entity on the New York Stock Exchange. As the ultimate owner of the brand, Markforged Holding Corporation continues to oversee the development of its Integrated Additive Manufacturing Platform, which includes the Eiger software, industrial hardware, and specialized materials like Onyx. The brand remains a leader in the digital manufacturing sector, headquartered in Watertown, Massachusetts.
