A point group mold, whose surface consists of tips of pins arranged to form the desired shape, was newly used to fabricate Al foam with complex shapes. Although dimples formed by the pin tips were clearly observed, the surface of the Al foam retained the shape of the point group mold. No protrusion of the Al foam through the gaps between the pins during foaming was observed. Namely, the surface of the point group mold was transferred to the Al foam.
