The invention discloses a layer thickness self-adaption method and system for 3D printing concrete. The system is used for achieving the method. According to the method, the technical problems that in traditional fixed layer thickness printing, single-layer thickness deviation accumulation is caused by factors such as material fluctuation, and then total height errors of components and uneven layers are caused are solved. The method comprises the steps that after printing of each layer (N layers) is completed, three-dimensional shape information of the upper surface of the layer is obtained through the surface scanning distance measuring unit, and actual height distribution data are generated; comparing actual data with theoretical model slice data, and calculating height deviation information; on the basis of the deviation information, generating a compensation strategy comprising a reference height adjusting instruction for the fine-adjustable printing platform and / or a dynamic adjusting instruction for printing parameters of the next layer (N + 1); and finally, executing the strategy and starting printing of the next layer. Closed-loop feedback control in the printing process is achieved, errors can be compensated layer by layer in real time, and the overall size precision and interlayer quality of a printed component are effectively improved.

The invention provides a method wherein single layers of a wall element, consist of two (or more) strands. One of the strands is located at one side of the layer and another one of the strands is arranged at the other side of the layer. However, at one or more positions these sides may be changed. In this way, e.g. color, reflectivity, transmissivity, and or other optical properties may be controlled. Further, a strong(er) layer may be obtained. Printing becomes more flexible, as the two strands may essentially be printed continuously. There will thus be change positions within the layer where one strand is over the other, or vice versa. In order not to increase layer thickness (at those change positions), as all strands are within the same layer, at the change positions the layer thickness of the strands may be decreased. In specific embodiments, there may be a temporary stop during printing of one of the strands at the change position to provide space for the future strand. A kind of woven structure may be obtained, which may also provide strength. Especially, one of the strands may be transmissive for visible light. This may provide a light transmissive single layer, or a light transmissive wall element.
