| Summary: | The subject matter disclosed herein relates to additive manufacturing techniques, and more specifically, to additive manufacturing techniques that involve binder jet printing. A disclosed additive manufacturing system for fabricating an article includes a build unit and a positioning system operably coupled to the build unit. The positioning system is configured to move the build unit in at least three dimensions. The build unit includes a recoater portion configured to deposit a layer of powder within a build area of the additive manufacturing system. The build unit also includes a binder jetting portion configured to selectively deposit and cure a binder within a periphery of the deposited layer of powder to form a dynamic build envelope around the article being fabricated in the build area. |
