Abstract
An apparatus for fabricating a 3D object. The apparatus may be comprised of a charged powder transferring system, a first charged powder layer generating device, a second charged powder layer generating device, a powder layer consolidation station, and an object build platform. In operation of the apparatus, a portion of a powder transferring surface of the flexible web traverses a directional change member during cyclic motion, and exceeds a radius of curvature defining a delamination threshold between the powder transferring surface and a first fused slice of the object. The apparatus may include an oven operable to fuse a stack of delaminated fused slices on a support substrate into a fused stack comprising fused second powder material and fused first powder material forming at least a portion of the object. A method of fabricating a 3D object is also disclosed.
