Description
technical field [0001] The invention relates to the field of building manufacturing, more specifically, it relates to a 3D printing concrete extrusion device for building. Background technique [0002] 3D printing technology (3D Printing Technology), also known as additive manufacturing (Additive Manufacturing), is an emerging manufacturing technology. Compared with traditional manufacturing technology, its most prominent feature is its close integration with digital models, and it is a technology with real potential to achieve "what you see is what you get". The working principle of 3D printing is to extrude and accumulate materials layer by layer through the nozzle of the printer according to the printing path generated based on the digital model to form a three-dimensional entity. In the field of engineering construction, enterprises and researchers also want to apply this new technology to traditional construction, providing new solutions for the development and sustain...
