Depends what "very specific and functional shapes" you have in mind, I guess. For my use of a 3D printer, I believe something like OpenSCAD is going to be a significantly more efficient textual description of the object than ~english -- for me and the computer.

OpenSCAD will definitely be more efficient but not as many people speak it fluently. When we learn or talk about objects, we do it in English, even if we have to resort to very technical jargon. I think this is a case of opening it up to more people rather than making it more efficient for people who already do this.
