摘要： Powder—based additive manufacturing processes for producing integral parts with multiple metallic materials are disclosed. The integral parts are printed as single pieces by joining different metallic materials together during printing. A combination of different powder-based additive manufacturing processes or the same process can be used to produce the integral part.

摘要： Additively manufactured thrust chambers and thrust chambers with integral fluid manifolds, and hybrid additive manufacturing methods for their production, are provided. Hybrid additive manufacturing techniques may combine a variety of processes including, WAAM, PBF, cold spray and DED, for example, to produce objects with variant dimensional requirements, i.e., large overall size and small features. Hybrid additive manufacturing may be defined as provide various process layers within any manufactured object. These process layers in turn allow for the introduction of variable feature and size distribution throughout the manufactured object. Hybrid process layers according to aspects may also allow the use of a variety of materials or may use a single material across the various process layers.
