One of the main challenges of modern manufacturing is the dilemma between scale and scope, i.e., the ability to produce high volumes at low prices, yet systematically integrating the increasing demand for individuality in the products. As a consequence, concepts for one piece flow at the cost of mass production are developed. Laser based manufacturing systematically resolves this dilemma and provides an extreme degree of flexibility and precision. In principle, parts can be designed totally independent of the manufacturing process, by focusing on the functionality of the part like static and dynamic stability or stiffness. In parallel, economic and ecologic demands such as light weight, deformation behavior by mesh structures and scaffolds or even other functionalities like conductivity can be integrated. Because the production chain leaps directly from the computer into the part and no tools are required, the process is also referred to as “Digital Photonic Production.” Examples of this process are Selective Laser Melting, Laser Metal Deposition and Ablation by ultrafast lasers.  Continue reading →
