Presenting... the DEployable Spin Gravity Array. Folded form is tall and narrow, deployed form is a wide torus.Still a work in progress (doesn't deploy and fold up cleanly yet), but since I showed the models above, I thought you guys might be interested to see the 3D print.
Nanyang Technological University Researchers Improve Ultrasound Technology With 3D Printed Lenshttps://3dprint.com/153984/3d-printed-ultrasound-lens/"The main difference between standard ultrasound devices and the NTU device is that instead of glass, the lens, or transducer, is 3D printed with clear photopolymer resin from Formlabs. 3D printing allowed the research team to create lenses in any shape – meaning that they could generate acoustic waves of any shape, unlike glass lenses which are limited to simple planar, cylindrical or spherical shapes. 3D printing more complex lenses allowed the researchers to focus the waves at multiple points at once, as well as to control the phase of the waves and focus them on different points at different times."

I couldn't think of any, except for materials inspection maybe, so interested to know.
