Abstract
A method of producing a three-dimensional form includes the steps of spraying from at least one nozzle a gas including particles of materials having different properties onto a base surface to deposit a layer of particles, repeatedly spray-depositing layers of particles each on the upper surface of a deposition layer, thereby building up a three-dimensional object consisting of the accumulated deposition layers each having different properties in a two-dimensional plane, and utilizing the different properties in the accumulated deposition layers to remove part of the three-dimensional object, thereby producing a desired three-dimensional form.
