Biqu is a brand released by BigTreeTech. They are a little different, yet very similar to Creality machines - they share a lot of the same basic parts/styles. They tend to have much flashier looks and screens, and more bells and whistles. Still a easy to operate machine, parts are a little more of a strain to get, and tend to be a bit more on the expensive side. The reason why is BigTreeTech tends to have a bit more emphasis on higher end equipment, that they manufacture themselves. They are a well known 3d printer after-market manufacturer.
