<p>A fused deposition process is used to form three-dimensional solid objects (100) from a mixture including a particulate composition dispersed in a binder. The object (100) is formed by depositing the mixture in repeated layers of predetermined thickness, with each layer solidifying before the next adjacent layer is deposited. Following formation and a binder removal step, the object (100) may be at least partially densified to achieve preselected properties. The process permits three-dimensional objects (100) to be formed relatively quickly and inexpensively, without the need for molds or other tooling.</p> |
