This 4^th International Conference on 3D Construction Printing (4-IC3DcP) is scheduled to be held on 19-21 July 2023 at Nanyang Technological University (NTU, Singapore). This follows the inaugural one held at Swinburne University of Technology in Melbourne (Australia) in November 2018, the 2^nd one held at Hebei University of Technology in Tianjin in October 2019 and the 3^rd conference held online in June 2022 and mainly organized by TongJi University, Shanghai. Separately, in May 2021, Southeast University (Nanjing) organized an International Conference on 3D Printing Concrete Materials and Structures held online.

We welcome all participants back to a physical format, in July 2023, and hope to rekindle all ties, networks, cooperation and relationships in our very special community; and trying to spearhead change in an important industry, viz. Construction. We would also like to promote collaborations between the scientific communities and industries, share our achievements and make significant progress in all our endeavors.

The Scope of the conference covers all aspects of Construction 3D Printing, to include established technology, modeling, simulation, materials, recycled materials and concrete, geopolymer, fiber reinforcement and composite materials, testing and standards, applications, Building Information Modeling (BIM), design, optimization, structural and intelligent monitoring, robotics and automation.

The organizers will publish all accepted papers in a Special Issue by Springer titled: 3D Printing in Building & Construction.
