A type of sheet lamination additive manufacturing that uses a two-step process – stacking and bonding. Successive sheets of aluminum are stacked, and the perimeter is cut to the desired outline of that layer. A chemical is then applied to the new top layer to suppress bonding with the next layer. This process repeats until After all the layers are built, the stack is placed into a bonding machine where the layers are heated and pressed against one another to bond where suppressing material was not applied.
