Abstract: 3D printing technology has disrupted the traditional manufacturing process, which covers widespread applications across various sectors, including aerospace, automotive, medical, construction and cultural innovation engineering. The sources of concrete raw materials are wide and low in cost, having good placeability, and widely used in civil infrastructure. In the context of modern information and automation, 3D printing technology combined with concrete produces 3D printing concrete (3DPC) can not only effectively save raw materials and environmentally friendly construction, but also enable more flexible construction of various types of assembled structures with high automation. However, 3DPC still has many limitations, such as low tensile strength, inferior earthquake resistance, reinforcement problems and low inter-layer bonding strength, etc. Various reinforcement techniques need to be developed to improve performance. Here, this paper focuses on the impact of various reinforcing techniques involving steel bar reinforcement, fiber reinforcement, and other reinforcement methods, on the performances of 3DPC, and expounds the possible problems and future development trends.

Key words: 3D printing, concrete, reinforcement technology, printing property, mechanical property, fiber
