To fabricate aluminum foam having nonporous surface layer (sandwich structure), the selective laser melting (SLM) was applied to fill surface pores of a commercial closed-cell type aluminum foam with aluminum. A commercially pure aluminum powder was continuously melted and solidified by irradiating with a pulsed Nd:YAG laser with a maximum average power of 50 W. As a result, the aluminum foam having nonporous surface layer (SLM surface layer) was successfully fabricated. The compressive deformation behavior of the fabricated aluminum foam having the SLM surface layers was investigated with uniaxial compression test. The plateau stress of the aluminum foam having the SLM surface layers was improved by approximately 20%, compared with that of the aluminum foam without the SLM surface layers.

To improve mechanical properties of a closed-cell type aluminum foam, the surface pores are filled with aluminum powder by selective laser melting (SLM). The relationship between the laser irradiation conditions and solidification characteristics of aluminum powder is investigated with one-line laser irradiation on the aluminum powder with a thickness of 5 mm. The aluminum powder is continuously melted and solidified with laser spot diameter of 0.6 mm and scanning speed of 10–20 mm/s. According to the successful melting and solidification conditions, the SLM is applied to the surface pores of a closed-cell type aluminum foam supplied with aluminum powder. The supplied aluminum powder is confirmed to be successfully melted and welded to the aluminum foam. As the result, the aluminum foam with nonporous surface layer (sandwich structure) is fabricated by the SLM with aluminum powder. The compressive behavior of the fabricated aluminum foam with nonporous surface layer is investigated.
