Three-dimensional modeling apparatus

摘要

A three-dimensional modeling apparatus fabricates a 3D object by applying a binding material to a powder material to bind the powder material thereby to form bodies of bound powder material in sequence. The apparatus aims to form layers of uniform thickness at high speed without an increase in size. This apparatus comprises a powder spreader mechanism and a powder supply mechanism. The powder spreader mechanism is movable toward a predetermined travel direction for spreading the powder material along the travel direction to form a layer of the powder material. The powder supply mechanism is configured to move along the travel direction of the powder spreader mechanism for supplying the powder material ahead of the powder spreader mechanism along the travel direction.
