“…Most of them use adhesives [ 12 , 13 ], but methods that require no adhesive have also been proposed, as described below. For example, there are some attempts to thermocompress resin sheets onto heated aluminum foam such as the combination of aluminum alloy sheets with porous layers and Polyamide-6 [ 14 , 15 ], aluminum alloy sheets with porous layers and carbon fiber-reinforced thermoplastic [ 16 ], and aluminum foam with polycarbonate [ 17 , 18 ]. Composite materials of open-cell aluminum foam with interpolation of polyurethane, silicone polymer rubber, and epoxy resin have also been attempted [ 19 , 20 ].…”

Aluminum foam has relatively low tensile and flexural strengths because it is composed of many pores with thin cell walls. One method of strengthening aluminum foam is to fabricate a composite material with a dense lightweight resin. In this study, the fabrication of composite materials by directly printing resin on an aluminum foam surface using a 3D printer was attempted. The resin was directly printed on both heated and unheated aluminum foam. It was shown that composite materials consisting of aluminum foam and resin can be fabricated by directly printing resin with a 3D printer on both heated and unheated aluminum foam. The resin was softened during the printing process in the case of directly printed resin on heated aluminum foam, allowing more resin to penetrate into the pores than in the case of directly printed resin on unheated aluminum foam. In addition, it was shown that resin can be directly printed on the aluminum foam with a high bonding strength, as a large amount of resin penetrated into the pores, resulting in an anchor effect. That is, composite materials consisting of aluminum foam and arbitrary-shaped resin with relatively high bonding strength can be fabricated when a large amount of resin is allowed to penetrate into the pore.
