Magnesium Oxide (MgO) 3D Printing: High-Temperature Ceramic Brake Disc
Introduction
Magnesium Oxide (MgO) 3D printing offers new capabilities in manufacturing high-temperature, high-durability ceramic components, particularly for extreme performance applications like ceramic brake discs. By applying advanced ceramic 3D printing technologies such as Vat Photopolymerization and Binder Jetting, Magnesium Oxide (MgO) parts achieve exceptional thermal resistance, mechanical strength, and chemical stability.
Compared to traditional ceramic forming methods, MgO 3D printing enables the production of complex, customized designs with faster turnaround times, optimized weight distribution, and improved thermal performance.
