Rapid prototyping apparatus for producing three-dimensional object, comprises carrier whose height is fixed and retaining wall whose height is adjusted by program-controlled adjuster

摘要

An apparatus for producing a three-dimensional object by rapid prototyping, comprising a carrier (6) surrounded by a retaining wall (10), an applicator (11) for depositing successive layers of a construction material (4) on the carrier and a device (12) for irradiating the layers in positions corresponding to the cross-section of the object, comprises a carrier whose height is fixed and a retaining wall whose height is adjusted by a program-controlled adjuster (15).
