This book explores the challenges of 3D printing with abrasive materials, focusing on carbon fiber-infused filaments and their impact on standard brass nozzles, which wear quickly. It investigates the unique properties of these composites, which combine carbon fibers with base materials like PLA and PETG, offering increased strength but posing abrasion-related challenges. The research suggests using hardened steel or tungsten carbide nozzles for improved durability and offers strategies to optimize printing processes by adjusting temperature, speed, and retraction. Practical tips on nozzle maintenance and proper filament storage are proposed to enhance print quality and reduce clogging. Ultimately, the thesis aims to empower users to navigate the complexities of abrasive material printing and contribute to the advancement of additive manufacturing technology.
