摘要： The present disclosure generally relates to methods of additive manufacturing with control of the energy beam incidence angle that allows for aligning the laser beam angle to directly oppose the building direction of an angled wall. The method includes building an object in an additive manufacturing powder bed where the object includes a surface that is defined by a build vector projecting outward relative to the build plate center at an angle Φ relative to normal of the build plate such that 90°>Φ>0° and the directed energy beam forms an angle θL2 relative to normal of the build plate such that 270°>θL2>180°, wherein θL2−Φ=180°±Δ, and Δ

摘要： The present disclosure generally relates to methods and apparatuses for secondary material deposition and insert deposition during additive manufacturing (AM) processes. Such methods and apparatuses can be used to embed chemical signatures into manufactured objects, and such embedded chemical signatures may find use in anti-counterfeiting operations and in manufacture of objects with multiple materials.
