Compositional Control in Solid Freeforming; Fabrication of 3D FGM
Three dimensional functional gradients have been prepared from fine powders by direct ink-jet printing using two methods for ink mixing and for coarser, free-flowing powders by acoustic deposition. Each of these methods can provide compositional accuracy of about 3 wt.%. These are 2nd generation technologies for computer control of both shape and composition. The techniques are described and their potential discussed in terms of resolution and compositional accuracy.
