  • Publication number: 20240219027
    Abstract: 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.

  • Publication number: 20230173601
    Abstract: A 3D printer can print a structure by depositing material into a weld pool that is moving relative to a workpiece. An electrode wire can supply energy to the weld pool while being fed at a first feed rate into the weld pool. A second wire can be fed into the weld pool at a second feed rate to deposit additional material and thereby speed up the overall material deposition rate. All of the energy in the weld pool may be supplied by the electrode wire. The printer can dynamically control the first feed rate and the second feed rate during printing. A mathematical model can be used to determine the second feed rate as a function of the first feed rate, the energy put into the weld pool, and the print head travel speed. The second feed rate may optimize the material deposition rate according to the model.
