Abstract
The invention relates to a method for manufacturing a turbine engine blade () including an active-surface wall () and a passive-surface wall () separated from one another, this blade () including a tip that has a closing wall grouping together the active-surface () and passive-surface () walls in the region of this tip to define the bottom () of a bathtub tip shape located at the tip of the blade, the method comprising a moulding step implementing a core defining the bathtub tip shape. According to the invention, there is a step of adding metal to the bottom () of the bathtub tip by means of a Direct Laser Additive Manufacturing (CLAD) method, to deposit material onto the bottom of the bathtub tip to form therein an inner partition () supported by the bottom thereof ().
