Abstract
A method of fabricating a part includes stacking sheets of fusible material to form a stack. The method also includes directing a laser beam through at least one sheet of the stack. The method also includes transferring energy from the laser beam to multiple locations on at least one interface between adjacent sheets of the stack, according to a predetermined pattern corresponding with a design of the part, to form corresponding multiple molten regions. The molten regions are conjoined together to form a fused portion of the adjacent sheets. The fused portion of the adjacent sheets defines the part.
