Abstract:
A solid freeform fabrication process for making a three-dimensional object comprising the steps of:operating a material deposition sub-system comprising a multiple-channel liquid droplet deposition device for supplying multiple liquid compositions and ejecting said liquid compositions in the form of droplets on demand and a solid powder-dispensing device for discharging powder particles to predetermined locations; providing an object-supporting platform in close working proximity to said material deposition sub-system to receive said liquid droplets and powder particles therefrom; during said material deposition process, moving said deposition sub-system and said object platform relative to one another in a plane defined by first and second directions and in a third direction orthogonal to said plane to form said liquid droplets and powder particles into a three dimensional shape.
