Hong Kong Institute of Project Management (HKIPM) Seminar and Guided Tour to RCC3D

Organized by the Hong Kong Institute of Project Management (HKIPM) and co-hosted by the PolyU-NAMI 3D Concrete Robotic Printing Research Centre (RCC3D), the Research Centre for Resources Engineering towards Carbon Neutrality (RCRE), and the Department of Building and Real Estate (BRE) and Department of Civil and Environmental Engineering (CEE) at The Hong Kong Polytechnic University (PolyU), the seminar "3D Eco-Concrete Printing for Hong Kong’s Construction Industry" was held successfully on 28 October 2025. The event featured insightful presentations from three distinguished speakers: Dr Jacky Chung (Deputy Director, RCC3D), Ir Lucas Lam (Assistant Centre Manager, RCC3D), and Dr Junli Liu (Postdoctoral Fellow, CEE). Attendees also participated in a guided tour of RCC3D’s facilities following the seminar, providing a firsthand look at the innovative technologies discussed.  

Delegation Visit of the Hong Kong Federation of Innovative Technologies and Manufacturing Industries (FITMI) to RCC3D

A delegation from FITMI visited RCC3D on 3 October 2025. During the visit, Dr Jacky Chung, Deputy Director of RCC3D, provided an insightful overview of the center’s development, research focus, and recent achievements. Team members Dr Junli Liu, Dr Xiaosheng Li, and Ms. Eunice Li delivered in-depth presentations on cutting-edge 3D concrete printing technologies, highlighting the advanced equipment and demonstrating a range of practical applications. The visit facilitated meaningful exchanges between FITMI delegates and RCC3D researchers, fostering opportunities for future collaboration and innovation in the field of 3D concrete printing.

Artificial Reef Project by PolyU's RCC3D in Collaboration with D-Shape

We are excited to announce a partnership between PolyU’s RCC3D (featuring members from the Department of Food Science and Nutrition and the Industrial Centre) and D-Shape. Together, we have developed a mock-up model of an artificial reef using advanced large-format cementitious-based binder jetting technology. This model is designed for educational purposes and we showcased it at the 10th UBS Disruptive Technology CEO Summit 2024, hosted on November 20th at the Regent Hong Kong. This nature-inclusive marine structure mock-up model illustrates innovative approaches to enhancing marine biodiversity and demonstrates the resilience required to withstand extreme weather conditions.
