A rotary additive manufacturing system for producing 3D parts in a layer-wise manner includes a silo support, a tool support, a plurality of silos, and a part developer. The tool support overlays a first side of the silo support, and is configured to rotate about a central axis relative to the silo support. The silos are each attached to the silo support and extend along the central axis from a second side of the silo support that is opposite the first side. The part developer is supported by the tool support, and is configured to build a 3D part within each of the silos in a layer-by-layer manner during rotation of the tool support relative to the silo support.
