A new approach of coupling additive manufacturing and conventional sintering methods for the fabrication of dense-porous hybrid structures with complex geometries and controlled porosity is presented. The critical effects of the procedure used to fill host electron-beam printed dense structures are investigated. The occurrence of flaws in the powder packing and their changes after different sintering cycles are emphasized. It is concluded that manual filling of the printed boxes after their complete de-powdering provides defect-poor structure with good interfaces between the dense and porous zones.
