Surface pores of a closed − cell type aluminum fbam were filled with aluminum powder by selective laser melting ( SLM ) . The relationship between the laser irradiation conditions and solidification characteristics of aluminum powder was lnvestigated with one − line laser irradiation . The aluminum powder was continuously melted and solidified with a Iaser spot diameter of O. 6 mm and a scallning speed of 10 − 20 mm ! s. According to the successful melting and solidification conditions , SLM

As the result , the a ] uminum foam with nonporous surface layer ( sandwich structure ) was successfully fabricated .
