I could only find a few articles on fully 3D printed small gas turbine by PTC - dated May 2023, Israeli tech research 2023 & Sierra turbine - 2020, I imagine there are many more SO doesn't look 'novel and/or new so unless they have somehow re-invested some part of the design and/or manufacturing process, not looking good for a patent.
All the same, with all the interest in drones ATM, it will be interesting to see where this goes.
