摘　　要：3D打印技术颠覆了传统材料的成型工艺,广泛应用于航空航天、汽车制造、生物医疗、建筑工程等领域。混凝土原材料来源广且成本低,可塑性良好,在基础设施领域应用广泛。在当今信息化和自动化大背景下,3D打印技术与混凝土结合生产的3D打印混凝土(3DPC)不仅能有效节省原料、环保施工,而且能够更加灵活地建造各类智能自动化程度高的装配结构。然而,目前3DPC仍存在抗拉强度低、抗震性差、配筋难、层间黏结强度低等诸多局限性,需要发展各种增强技术来提高性能,所以本文利用钢筋增强、纤维增强和其他方法增强方法分别论述各类补强材料对3DPC性能的影响,并且指出可能存在的问题和未来发展趋势。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.
