Automated system for forming objects by incremental buildup of layers
First Claim
1. An automated system for manufacturing an article that is formed by the incremental buildup of layers onto a work surface comprising:
- a movable work surface onto which layers are deposited to form the article;
a material deposition station sized and positioned to receive the moveable work surface, where each layer of the article is deposited onto at least one of the work surface, a substrate placed on the work surface and a preceding layer, wherein each layer deposited on a preceding layer is simultaneously deposited and bonded to the preceding layer to form a portion of the article;
at least one processing station sized and positioned to receive the moveable work surface, each processing station capable of performing a desired operation on selected layers of the article; and
an article transfer apparatus sized and positioned for repetitively placing, removing and returning the work surface and any layers formed thereon at the deposition station and at the at least one processing station until each layer is processed and a completely manufactured article is produced.

Abstract
A system and method for manufacturing an article that is formed by the incremental buildup of layers on a work surface contains a material deposition station to deposit the layers. In addition, a plurality of processing stations are employed. Each processing station performs a separate function such that when the functions are performed in series, a layer of the article is produced and is prepared for the deposition of the next layer. An article transfer apparatus repetitively moves the work surface and any layers formed thereon selectively among the deposition station and the processing stations. The article transfer apparatus continues to move between the processing stations until each layer is processed and a completely manufactured article is produced.
