The outfit for the stationary shoulder friction stir additive manufacturing(SSFAM) is described and a block-shaped additive material is formed. It is shown that, with a special stir tool, at certain of rotational speed, travel speed and material thickness in each additive layer, an additive material without any defects can be obtained. Only less than 1 mm allowance at each side of the block-shaped additive material needs to be cut out. The effective utility ratio of material for the SSFAM is about 78%, much higher than the method used the common FSW. For the 2024 Al-alloy additive material with a 50mm high and 6mm width, the hardness is about 95Hv at the top layer and is harder than the bottom layer. But at the same horizontal position, the hardness changes rather little. The tensile strength at the top part of the additive material is about 340Mpa, higher than the bottom part.
