1. An additive manufacturing device comprising:
a build platform;
a recoater operatively connected to the build platform to move relative to the build platform to coat unfused powder onto a build on the build platform, wherein the recoater includes a recoater mount defining a length-wise receptacle therein, and a recoater blade seated in the receptacle; and
a blade reel system operatively connected to the recoater to replace the recoater blade in the receptacle during a build on the build platform, wherein the blade reel system includes a first supply reel and a first take up reel, and a second supply reel and a second take up reel on an opposite end of the build area from the first feed reel and the first take up reel, wherein the blade reel system is mounted stationary relative to the build platform outside of a build area, wherein each of the first supply reel and the second supply reel are configured to feed fresh recoater blade material into the receptacle, replacing used recoater blade material, wherein the blade reel system includes a cutter operatively connected to cut fresh blade material to free the recoater from the blade reel system to recoat the build area using the fresh blade material.
