Welcome from the Chair
Hello everyone, and a very warm welcome to our webinar on “High-Precision Fabrication via Laser-Based Additive Manufacturing.” I'm delighted to serve as your chair for this exciting session.
Today, we explore how laser-based techniques are pushing the frontiers of additive manufacturing—from nano- to macro-scale, across both polymeric and metallic materials.
We’re honored to have four distinguished researchers with us:
-
Dr. Wenqi Ouyang will present a groundbreaking holographic two-photon polymerization (TPP) system, enabling high-speed, high-resolution 3D nanofabrication.
-
Dr. Haitao Ye will dive into smart multimaterial DLP printing, showcasing adaptive energy-dissipating structures with real-world applications in biomedical and vibration control systems.
-
Dr. Shuo Qu will close with his pioneering work on micro laser powder bed fusion (LPBF) of copper, where material design meets advanced laser processing for high-performance microdevices.
-
Dr. Junhao Ding will introduce an STL-free toolpath strategy for μLPBF that improves printing efficiency and enables mechanical enhancement through controlled imperfections in metallic lattices.
Together, their insights span the full laser-based AM workflow—from optical system design to material innovation and process optimization.
