Solid Freebody Forming of Ceramics from Polymerizable Slurry

摘要

A system is described for forming three-dimensional parts from a polymerizableslurry. This liquid is delivered from a fine nozzle to build up the component as a series of layers described from a CAD drawing of the part. This is one of a family of solid freebody forming methods. The layerwise process leads itself particularly to chemically synthesized materials where shrinkage and mass transport are major problems. The technique also has considerable potential for combining various materials into a single component. (MM).
