Steel production by 3-D printing
Research investigates effect of additive manufacturing on aerospace materials
Aerospace vehicles - airplanes, helicopters, rockets, spacecraft, satellites and others - are subject to extreme conditions of temperature, pressure and mechanical load during their operation. Thus, materials and manufacturing methods used in the aerospace industry are constantly evolving, always seeking increased reliability and weight reduction without sacrificing mechanical performance.
An important class of materials for the aerospace industry is the Maraging steel. They feature high mechanical strength and are used in components such as landing gear for airplanes or helicopters and even rocket fairing, which are subjected to high mechanical loads and fatigue cycles.
Additive manufacturing – popularly known as 3-D printing – has revitalized the manufacture of components with shapes previously considered challenging, or even impossible, and increased the potential for use of different engineering materials. However, although the structure and chemical composition of a given material is known, the product obtained in the additive manufacturing process is fundamentally different from what is obtained by conventional manufacturing processes such as casting or welding.READ MORE
