Abstract

Powder manufacturing operations can be classified by dimensional order. In injection moulding, artefacts arc assembled by volume; in paint deposition, lithography^ and screen printing by plane; in circuit printing and extrusion frccforming by line and in jet printing by point. This paper describes frceform microcngineering methods in which components are assembled from droplets of well-dispersed suspension. These include multiple layer paint deposition, continuous and drop-on-demand jet printing and, for extreme resolution, the electrostatic deposition of 2-3 usn droplets in cone-jet mode. These lower order operations may be slower but they open up possibilities for computer controlled microstructure such as functional gradients and for miniaturisation.
