Abstract Scope |
Many applications of interest for 3D printing require the use of more than one material in combination to achieve functionality and improved properties. A multi-material approach to high-resolution lithography-based ceramic manufacturing will be presented. Co-printing of different ceramics or even metals in separate layers of a printed part is possible, as well as spatially-resolved combinations within a single layer. This technique paves the way to achieve complex bi-phasic ceramic components. Successful trials that will be presented here include combinations of alumina with colored alumina; zirconia with colored zirconia; and alumina with molybdenum-alumina cermet. The presentation will cover the actual multi-material 3D printing process with a focus on the results and current challenges in terms of co-sintering different ceramic materials. Initial results show that this technological approach holds great potential to pave the way from classical single material structures to bi-material components, and subsequently multi-material and functionally-graded ceramics. |
