An integrated box-type 3D printing device, having a support structure, a first bracket, a second bracket, and a printer body. The first bracket is movable back and forth in a first direction on the support structure. The printer body is arranged on the second bracket. The second bracket is movable back and forth in a second direction relative to the first bracket. The printer body is movable back and forth in a third direction on the second bracket. The support structure is provided with an accommodating space for accommodating the second bracket. The second bracket is foldable in the opposite direction to the third direction so that the second bracket is foldable into the accommodating space so that the integrated box-type 3D printing device assumes a transport and storage configuration when the second bracket is folded into the accommodating space.
