Binder jetting with metal
Binder Jetting - the powder bed based 3D printing with metal
Lightweight, corrosion-resistant, precisely manufactured – these properties describe only a fraction of the requirements placed on metallic components.
We develop materials, inks and the manufacturing process adapted to your requirements. We accompany the development with modern analysis methods of the unsintered and sintered parts. Hereby we ensure that our development for you meets the high requirements.
We have over 15 years of experience in evaluating powders for the 3D printing process Binder Jetting. The requirements from a 3D printing perspective are the same, although metals and ceramics differ significantly in their sintering behavior and, of course, in their subsequent properties.
Optimum wetting of the powder bed with the ink is a basic requirement for an optimum component. We attach great importance to the development of an ink with constant processing properties over a long period of time. By using particles in the ink, we can significantly increase the density of the manufactured components, which has a very positive effect on the mechanical and electrical properties.
Contemporary requirements need contemporary solutions: When a single material is not enough, multi-material binder jetting is the way to go. By adding particles to the ink, it is possible to introduce a material into your component that is different from the base material layered in the print bed. There is no other manufacturing process with such possibilities.
Printing with particle-filled inks opens up the possibility of changing structures and properties locally at the microscopic level. Various material combinations such as metal-metal or metal-ceramic are possible. For example, the addition of aluminum oxide to aluminum results in higher wear resistance.
Lowering the sintering temperature by adding low-melting metals is also possible, as is reactive alloying. This is just the beginning, the possibilities are endless.
These advantages, coupled with the geometric freedom of additive manufacturing processes, makes it possible to produce unprecedented components that point the way to a new generation of manufacturing and design.
