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.
Our main goal is to develop materials, inks and the associated process to secure the highest standard for the printed parts. Our development process is accompanied by modern analysis equipment to investigate the unsintered and sintered parts. Thereby, we ensure that our development meets the customer needs.
By developing crucial parts of the binder jetting process, we were able to support the additive manufacturing process of binder jetting for over 15 years. Although most of our experience comes from our main area ceramics, we are certain that we can transfer the knowledge to metals.
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 an incontestable 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 which differ from the material in the printing bed it is possible to create a multi material part. 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 a microscopic level. Various material combinations such as metal-metal or metal-ceramic are possible. For example, adding aluminium oxide to aluminium results in a 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, creates the opportunity to produce unprecedented components that point the way to a new generation of manufacturing and design.
