Conference Abstract: Using atmospheric carbon harvested by trees, Carbon Forest Products' 3D printing technology has the potential to change the landscape of additive manufacturing, providing sustainable, cost-effective, and high-performance alternatives to traditional materials. For certain applications, such as thermal management, this material can also eliminate supply chain exposure, offering consistent, eco-conscious manufacturing solutions. Sustainability is one of, if not the, most pressing priorities for the planet and global industries. Companies, aligning with CSR goals, seek sustainable materials. We are developing the world’s first patented 3D Carbon Composite printing process. Our unique process has overcome the previously impossible challenge of efficiently 3D printing carbon, potentially making it a viable option for industries demanding high-performance materials. We use refined lignin powder, a low-cost, renewable by-product of the paper manufacturing industry, as our primary ingredient. Lignin, with its semi-thermoplastic properties and high carbon content, is transformed into bespoke 3D geometries using laser-based printing technology. This material serves as the foundation for our sustainable products. Carbon composites offer incredible advantages, enabling cost-effective and high-performance solutions. They aim to be more thermally conductive than aluminum and lighter and more affordable than copper. As additive manufacturing evolves, CFP is at the forefront, pioneering new technologies and materials. Our 3D Carbon Composite has an extensive range of potential applications across industries and addresses limitations in the current 3D printing methods, offering a range of carbon-based composites and a low-cost, scalable process.
