This technology not only improves construction efficiency but also reduces material waste and environmental impact.

[0003] However, there are the following deficiencies in the prior art: The currently existing on-site 3D printing equipment for building components is divided into two types. One is a frame-type on-site 3D printing equipment for building components, and the other is an independent on-site 3D printing equipment for building components. The first frame-type one is large in volume, not easy to displace, and the installation is relatively cumbersome and complex. The second independent one is more flexible and convenient to carry, but its height is subject to corresponding limitations. At the same time, both of them have the situation that the edges of the printed building components are circular arcs or unevenly stacked, resulting in the need for secondary trimming in terms of appearance.
