Problems solved by technology

However, the coverage area of ​​each binder nozzle is small, and it needs to complete the horizontal and vertical movements in sequence to completely cover the designed model, and the printing speed is still slow
In addition, the printing equipment of the above two patents is only suitable for additive manufacturing, and cannot perform subtractive manufacturing such as cutting cracks, so complex geological models containing cracks cannot be produced

Abstract

The invention discloses powder bonding 3D printing equipment and method for preparing a complex geological model. The equipment comprises a rack, a transverse guide rail, a powder laying and bonding assembly stepping motor, a powder laying and bonding assembly, a small longitudinal beam stepping motor, a small longitudinal beam, a longitudinal guide rail, a crack cutting device stepping motor, a crack cutting device, a crack filling device stepping motor, a crack filling device, a lifting forming chamber and a control system. According to the powder bonding 3D printing equipment, through cooperative work among the steps of powder laying, binder injection bonding and forming, crack cutting, crack filling, lifting platform movement and the like, simultaneous printing of hard rock, soft rockand other multi-strength rock materials and a complex crack network is achieved for the first time through a layer-by-layer stacking method, and a high-precision complex geological model is prepared;and the problem of manufacturing a three-dimensional physical model of a complex geological structure is solved.

Description

technical field [0001] The invention relates to the fields of geotechnical engineering and mechanical engineering, in particular to a powder bonded 3D printing device and method for preparing complex geological models. Background technique [0002] Studying the catastrophe mechanism and damage characteristics of complex geological structures is the basis for ensuring the safety of major infrastructure and energy projects. Physical model testing is the main research method in the field of geotechnical engineering. However, due to the presence of rock materials of various strengths and discontinuous bodies and surfaces such as cracks in complex geological structures, there is currently no mature method for making complex geological structures. 3D physical model of the structure. [0003] 3D printing technology is a kind of manufacturing technology that has emerged in recent years, including cutting-edge technical knowledge in many aspects, and has high-tech content. Among the...
