Volumetric printers cure a whole part at once in a spinning vial of resin. SpinSlicer turns an STL into the projector frames: it models refraction, absorption and projector optics, shows a virtual print, and plays the frames. Free, MIT, Windows and Linux.

Could you build this?
Partial The STL import, UI, and frame playback are standard software work. The core value is an accurate optical model of refraction, absorption, and projector behavior for volumetric printing, which needs specialist physics and optics knowledge.
What it would actually take: The architecture would be a desktop app in C++ or Rust with a 3D viewer and a frame generator. The hard part is the physics: ray or beam propagation through a rotating resin vial, absorption and dose accumulation, and projector calibration. Building it needs an optics or photonics background, and validating the model against real printers requires hardware access and test prints.
