<\/span><\/div>Replacing aluminum components with 3D printed carbon fiber<\/h1><\/div><\/div><\/div><\/div>Recently, a severe aluminum shortage among industrial suppliers has led to sharp price increases. Since January 2021, aluminum prices have risen by over 50%, and experts expect the increase to continue over the next two years.<\/p>\n
According to Jyske Bank, the global aluminum shortage is due to increased material consumption based on three factors: increased spending on consumer goods due to economic stimulus packages, increased investment in sustainable technologies that rely on the use of aluminum (e.g., wind turbines, electric cars), and Chinese production and consumption of aluminum.<\/p>\n
Given this aluminum shortage, Markforged carbon fiber offers a suitable alternative. Many of our customers use it to replace machined aluminum parts. Carbon fiber has the highest strength-to-weight ratio among our continuous fibers. It is six times stronger and eighteen times stiffer than Onyx and is often used for components that replace machined aluminum.<\/p>\n
When embedded in a composite base material like Onyx, it can produce parts as strong as 6061-T6 aluminum. As a material, it is extremely stiff and strong and can be automatically embedded by Markforged 3D printers in a variety of geometries to produce optimized parts.<\/p>\n<\/div>

<\/span><\/div><\/div><\/div><\/div><\/div>What is carbon fiber?<\/strong><\/p>\nCarbon fibers consist of carbon atoms arranged in long, crystalline fibers with a diameter of only 5-10 micrometers. In modern manufacturing, several thousand carbon fibers are bundled into strands and combined with other materials to create a composite material. Combined with a thermoplastic or thermosetting resin matrix, carbon fibers can take on various forms used in technical applications.<\/p>\n
The specific material properties of carbon fibers make them ideal for a wide range of applications, including<\/p>\n<\/div>

<\/div><\/div><\/div>What makes carbon fiber an ideal replacement for aluminum?<\/strong><\/p>\nContinuous fiber reinforcement (CFR) technology allows carbon fiber to achieve strength similar to aluminum while replacing machined components.
