Numeric designationRSA-905 inhomogen
Chemical designationRSA-905 inhomogen
Stateinhomogen
Etching5 % NaOH

Same composition as in the case above, but with inhomogeneous microstructure after failed fabrication. The build-up structure from layer-by-layer solidification is still recognizable. The zones which appear white in the optical microscope and dark in the SEM image are almost pure aluminum.
