METHOD AND APPARATUS FOR FORMING OVERHANG STRUCTURES WITH A METAL DROP EJECTING THREE-DIMENSIONAL (3D) OBJECT PRINTER

A three-dimensional (3D) metal object manufacturing apparatus is operated to form sloping surfaces having a slope angle of more than 45° from a line that is perpendicular to the structure on which the layer forming the slope surface is formed. The angle corresponds to a step-out distance from the pe...

Zusammenfassung:A three-dimensional (3D) metal object manufacturing apparatus is operated to form sloping surfaces having a slope angle of more than 45° from a line that is perpendicular to the structure on which the layer forming the slope surface is formed. The angle corresponds to a step-out distance from the perpendicular line and a maximum individual step-out distance determined from empirically derived data. Multiple passes of an ejection head of the apparatus can be performed within a layer to form a sloped edge and the mass of the sloped structure is distributed within the sloped edge so the edge is formed without defects.
