Enhanced recoater edges

An additive manufacturing device includes a build platform. A recoater is operatively connected to the build platform to move relative to the build platform to coat unfused powder onto a build on the build platform. The recoater includes a recoater mount defining a length-wise receptacle therein, an...

Zusammenfassung:	An additive manufacturing device includes a build platform. A recoater is operatively connected to the build platform to move relative to the build platform to coat unfused powder onto a build on the build platform. The recoater includes a recoater mount defining a length-wise receptacle therein, and a recoater blade seated in the receptacle. A blade reel system is operatively connected to the recoater to replace the recoater blade in the receptacle during a build on the build platform.
