Abstract
There is now more openness about the idea that instruments, machines, and processes might have different uses from those intended by the designer or maker. This could benefit both the traditional and engineering ceramics industries. The connectivity of manufacturing pathways both within and between industries is beginning to be recognised in modern approaches to processing, and this recognition facilitates exchange and innovation. The present paper describes a change of purpose for ink jet printers to provide, inter alia, a solid freeforming (SFF) pathway to make components from a computer file by deposition of a well dispersed powder in suspension. Solid freeforming is defined as the creation of a three-dimensional shape by point, line, or planar addition of material without the use of confining surfaces other than a base. It complements the categories of casting, plastic deformation, joining, and machining as a core concept in manufacturing. It has its origins in stone and brickwork. Internal channels, cavities, and functional gradients can be created. Both the shape and the spatial arrangement of microstructure could be rendered from computer files. If this were just a prototyping method it would be interesting enough but it has the promises of a manufacturing pathway in which individuation can be conferred in a mass production operation and of a powerful route to large scale combinatorial libraries for materials discovery.
