APPARATUS FOR FABRICATING A THREE-DIMENSIONAL OBJECT AND METHOD OF ASSEMBLING AN APPARATUS FOR FABRICATING A THREE-DIMENSIONAL OBJECT
摘要
A printer (3) forms three-dimensional objects from a powder by selectively applying a binder liquid to incremental layers of the powder. The binder binds layers of the powder into solid two-dimensional cross sections of the desired object provided from memory. The printer can use dithering and halftoning techniques to shade the object and can also print in color. A filtration system removes airborne powder and recirculates the clean air. The printer also includes additional features to manage excess and airborne powder. <IMAGE>
