Abstract: A direct write or freeform fabrication apparatus and process for making a device or a three-dimensional object. By way of example the method comprises: (a) providing a target surface on an object-supporting platform; (b) operating a material deposition sub-system comprising a liquid deposition device for dispensing at least a liquid composition and a solid powder-dispensing device for dispensing solid powder particles to selected locations on the target surface; (c) operating a directed energy source for supplying energy to the dispensed liquid composition and the dispensed powder particles to induce a chemical reaction or physical transition thereof at the selected locations; and (d) moving the deposition sub-system and the object-supporting platform relative to one another in a plane defined by first and second directions to form the dispensed liquid composition and the dispensed powder particles into the device or object. An apparatus is also provided for carrying out this process.
