Silicon nitride is a promising engineering material characterized by the special combination of its properties such as extremely high strength and toughness, low thermal expansion, good thermal conductivity, high hardness, and extremely high chemical resistance [1, 2, 3] With this property profile, silicon nitride is predestined for extreme mechanical and thermal operating conditions as well … Read more
Metal Binder Jetting (MBJ) is an additive process in which binder is introduced locally into metal powder layers. The generated green parts are then debindered and sintered. In contrast to beam-based additive processes, hard materials can also be processed and, in principle, higher volumes or large, complex components can be produced more economically. Background The … Read more
FastCast Ceramics is a spin-off from Karlsruhe Institute of Technology (KIT) that focuses on ceramic solutions for the investment casting industry. Their innovative processing route based on capillary suspensions, suppresses stresses and thus crack propagation. Their first products aim for faster and more reliable shell building, concentrating on an accelerated layer formation as well as … Read more
Manufacturing of customised ceramic components of low dimensional tolerances and complex geometrical features with lot size one is a technological and economic challenge. If additive manufacturing technologies or conventional milling from blanks cannot deliver the required component strength or accuracy electric discharge machining (EDM) of ceramics present an attractive alternative as die sinking and wire … Read more
Additive or generative Manufacturing (AM) of components is currently attracting a lot of attention. The potential of the processes is addressed by research and development for many industry sectors, with ever new and modified processes being devised. At the same time, the first systems for aviation, medicine and tool-making have made the leap into commercialisation … Read more
The company 3DCERAM was created in 2009 and initially operated as a service bureau, manufacturing technical ceramic parts by 3D printing for large industrial companies. The choice of technology was made for stereolithography because of its high precision, high performance qualities, and its very fine surface appearance. These performances were identical to those obtained by … Read more
