Abstract
The efficient stabilisation of ceramics based nanopowders is a prerequisite for the achievement of highly reliable ceramic materials and for the development of three-dimensional printing technologies, recently known as Additive Manufacturing. Agglomeration due to Van der Waals forces can be avoided reducing the effective Hamaker values on the basis of refractive index matching [1,2] and more readily via electrostatic and/or steric stabilization using different formulation strategies to increase the (repulsive) barrier for agglomeration. We recently performed studies to stabilize alumina, magnesium-spinel and zirconia submicron/nanoparticles. Anion and cation type comb copolymers were applied as a promising dispersants in case of titania stabilisation [3,4]. Highly charged counterions were furthermore used to modify the electric-steric double layer [5] of mixed oxides. These slurries were successfully applied to the stereolithographic shaping of ceramics using a digital light processing (DMD-DLP) [7-11]. We present here our recent results related to DMD-DLP based Additive Manufacturing of ceramics, highlighting the need for advanced and appropriate powder treatment.
