Of course. We make miniature working models, powered by coal and steam. If you just meant the weirder types of loco, then yes to that too - someone will be making one. Turbine locos are not unknown and the Model Engineer magazine has had a long series on turbines in general going for a while now. 3D printing is only used for dummy detail parts. We mostly can't afford the type of printing required to make working bits. Laser cutting, water jet cutting and CNC machining are more prevalent at the moment.
