自2000年初至中期3D混凝土打印(3DCP)问世以来，随着相关材料、生产技术和诀窍的发展，这项技术的商业版图迅速扩大。为了评估3DCP技术在建筑领域的最新水平，本研究基于文献、专利和公开数据，对3DCP技术的发展和应用进行了系统的回顾和分析。通过专家评审，已经对3DCP的技术准备水平(TRL)进行了估计，证据表明，这一估计在TRL6-7范围内，与报道的聚合物熔融沉积模拟过程类似。提出了TRL评估过程的新模式，并将其应用于两个案例研究：1)装饰作品的生产；2)住宅的建造。最后，我们确定了四个研究和开发领域，这些领域应该被用来提高3DCP的TRL。
Since the inception of 3D concrete printing (3DCP) in the early to mid-2000's, the commercial landscape for this technology has expanded rapidly in parallel with developments of relevant materials, production technologies and knowhow. To benchmark the state-of-the-art of 3DCP technology in the construction field, this study presents a systematic review and analysis of 3DCP's development and applications based on information from articles, patents and publicly available data. An estimation of Technology Readiness Level (TRL) for 3DCP has been formulated through expert review, and the evidence suggests this is in the region of TRL6-7 similar to that reported for polymer-based fused deposition modelling processes. A new schema for the TRL assessment process is suggested and applied to two case studies: 1) the production of decorative works; 2) the fabrication of dwellings. Finally, we have identified four frontiers for research and development that should be exploited to raise the TRL of 3DCP.
