Abstract

This paper provides a critical review of the related literature on 3D printing in construction. The paper discusses and evaluates the different 3D printing techniques in construction. The paper also discusses and categorizes the benefits, challenges, and risks of 3D printing in construction. The use of 3D printing technology offers several advantages over traditional methods. However, it comes with its own additional challenges and risks. The main benefits of 3D printing in construction include constructability and sustainability benefits. The challenges are categorized into seven groups. The main challenges, found through the literature, are material related. The most cited challenges are material printability, buildability, and open time. Additionally, scalability, structural integrity, and lack of codes and regulations are frequently cited as major challenges. The additional risks are categorized into seven groups: 3D printing material, 3D printing equipment, construction site, and environment, management, stakeholders, regulatory and economic, and cybersecurity risks. The paper fills a gap in the literature as it addresses a new aspect of 3D printing, which is risk. The paper also provides some insights, recommendations, and future research ideas.

对建筑中3D打印的严格审查：优势，挑战和风险

摘要

本文对有关建筑中3D打印的相关文献进行了严格的评论。本文讨论并评估了建筑中不同的3D打印技术。本文还讨论并归类了建筑中3D打印的优势，挑战和风险。与传统方法相比，使用3D打印技术具有许多优势。但是，它还具有其他挑战和风险。3D打印在建筑中的主要优势包括可施工性和可持续性优势。挑战分为七个组。通过文献发现的主要挑战与材料有关。被引用最多的挑战是材料的可印刷性，可建造性和开放时间。此外，可扩展性，结构完整性，缺乏规范和法规经常被视为主要挑战。其他风险分为七类：3D打印材料，3D打印设备，建筑工地和环境，管理，利益相关者，监管和经济以及网络安全风险。这篇论文填补了文献中的空白，因为它解决了3D打印的一个新方面，即风险。本文还提供了一些见解，建议和未来的研究思路。
