I'm not sure if that's what this one is doing specifically, but there are metal additive-manufacturing machines out there that are 'hybrids' where they can print and mill as they go to effectively make 3d-printed parts with very good tolerance / surface finish. So they _do_ get finished with traditional machining operations, it's just done as its being printed out.
