About

Xirui Peng is a researcher specializing in advanced manufacturing, smart materials, and robotics automation, with a particular focus on pushing the boundaries of 3D and 4D printing technologies. Peng's most impactful contribution lies in the development of hybrid additive manufacturing approaches, most notably demonstrated in a 2021 paper integrating digital light processing (DLP) with direct ink writing (DIW) to produce functional structures and devices — a work that has garnered an impressive 229 citations and helped define a new paradigm in multi-process fabrication. Building on this foundation, Peng extended these hybrid techniques to the emerging field of 4D printing, authoring a highly cited 2022 study (162 citations) on freestanding liquid crystal elastomers capable of reversible, programmable, and rapid actuation — materials with transformative potential in soft robotics and responsive systems. More recently, Peng has broadened their research scope into intelligent automation, applying deep learning and reinforcement learning to optimize warehouse robotic picking systems in response to growing e-commerce demands. Collectively, Peng's work bridges cutting-edge materials science with practical automation engineering, earning over 390 citations and establishing a versatile and forward-looking research portfolio.
