Concr3de Alox Binder 5L
The BC1002 Alu Binderis also water-based ink, but with a twist. It is specifically designed to print dense alumina ceramics. It is able to make these dense parts because the binder is a suspension of nanoparticles that are printed as a slurry on an alumina substrate. This binder solves the low-density issue of alumina parts printed through binder jetting, as the nanoparticles fill the gaps between the grains in the powder. The consequence is a lower porosity and a higher density, therefore making the object less prone to be shattered and enhancing the material’s properties. The binder also provides green strength to the alumina parts, making them easy to depowder and gives the user the ability to create highly complex ceramic geometries. When using the alu binder, it is necessary to follow a standard alumina sintering process, where printed parts are debinded and then brought to high temperature, going from a green state to the final object. This unique particle filled ink binder was developed together with WZR in Germany.
