About ROME3D

ROME3D is a research group led by Prof. Huachen Cui in the Hong Kong University of Science and Technology (Guangzhou). We primarily focus on three aspects, including the development of advanced additive manufacturing (AM) techniques, the design and manufacturing of robots as well as the design and manufacturing of medical devices. We also investigate the design and AM of micro-architectures and metamaterials, the development of multi-functional materials as well as advanced packaging techniques.

Advanced AM Techniques

We are creating novel additive manufacturing techniques & synthesizing materials to fabricaite robots, medical devices and metamaterials.


We are designing and fabricaiting macro- and micro-scale robotic systems via AM techniques or hybrid manufacturing techniques.

Medical Devices

We are developing extracoporeal & implantable medial devices via additive manufacturing and hybrid manufacturing techniques.

We are born to create
