This belt printer something I've been working with @Creality3dprint on for over a year. Originally I tried to license through @printrbot or @NAK3DDesigns but we ended up developing it in house. All credit to @wjsteele for the amazing concept. https://twitter.com/ScaldaYT/status/1248233898481463296

I would say it's alpha version now. Infinite Z 3D printers are not like other printers where the issues are well known and easy to solve. It will be a little bit before it's ready for the public- but when it is, it should be a game-changer.
