3D printers are becoming so ubiquitous that even the higher-end machines like Form 1 and Form 2 are being used to make gaming projects like this Spacewar setup.
Matt Keeter used electronics and lasers from Form 2 and cover from Form 1, programmed it in Haskell and made a classic video game playable on a hardware of gutted SLA 3d printer.
Here is the hardware connected:
Here is a photo of the projected game objects, link to the video is listed bellow:
