1. A method of material build-up on a tip of a blade of a gas turbine engine, the method comprising:

  • inserting a material supply and an inflatable bladder between the tip and a shroud such that the material supply is exposed to the tip and the inflatable bladder is positioned between the material supply and a shroud;

    inflating the inflatable bladder to force contact between the material supply and the tip; and

    causing relative movement between the material supply and the tip, wherein the relative movement in combination with the radial biased contact between the material supply and the tip creates heat through friction.
