3D Printing in Construction: Current Status, Implementation Hindrances, and Development Agenda

3D printing (3DP) is regarded as an innovation that contributes to automation in civil engineering and offers benefits design, greenness, efficiency. It necessary objectively analyze the current status challenges associated with 3DP identify future research directions properly understand its construction applications. Previous has focused more on technical dimension of 3DP; however, nontechnical technology may hinder implementation thus must be paid particular attention to. This study presents a systematic review existing literature from both dimensions by combining quantitative qualitative studies. The was conducted using scientometric methods. analyzed information, including trends. Two aspects are presented, materials processes. In addition, trends economic, environmental, social, legislative proposed. provides comprehensive agenda advance proposes interests, challenges, topics. intended help practitioners systematically master processes assess application degree necessity 3DP.
