3D printing method for concrete product with complex shape

The invention belongs to the technical field of 3D printing, and discloses a 3D printing method for a concrete product with a complex shape. The preparation method of the concrete product in the complex shape comprises a product image acquisition module, a raw material weighing module, a central control module, a raw material mixing and stirring module, a product model construction module, a 3D printing module, a strength detection module and a display module. The technical problem that a three-dimensional model of a concrete product with a complex shape constructed in an existing method is inaccurate is effectively solved through the product model construction module; meanwhile, the strength detection module is used for collecting a rebound value by using a digital rebound apparatus, then the rebound value is analyzed and processed by using a cloud server, and finally an analysis and processing result is stored, so that the processing efficiency is high, and the data accuracy and reliability are high. 本发明属于3
