Summary: 3D printing, also known as additive manufacturing, eliminates the need for expensive molds or lithographic masks by directly converting computer-aided designs into delicate structures on demand. Light-based 3D printing, in particular, allows for high tunability in terms of printing format, speed, and precision. However, there are still challenges in achieving printing continuity, control over the printing process, and printing details. This article discusses and summarizes the field of slice- and light-based 3D printing from the perspective of interfacial regulation strategies and proposes potential strategies to construct complex 3D structures with distinct characteristics.

Summary: This study investigates the interface behavior between an orthotropic thin film and an orthotropic substrate. The integro-differential formulation with the aid of a membrane assumption is used for analysis. The loading scenarios include a constant temperature rise or a uniform compressive stress applied to the film edges. The results demonstrate the sensitivity of film stresses and shear stress singularity factor to different material combinations, with a significant increase in the shear stress singularity factor when the delamination length exceeds 50% of the film length. This study's findings are valuable for design engineers working on flexible and stretchable electronic devices.

Summary: The presence of bubbles at the interface of two-dimensional van der Waals heterostructures (vdWH) can alter the interfacial structure and result in novel functionality. Researchers investigate the dynamics of a bubble at the interface of a graphene-hBN vdWH using a NEMS device as a sensor, and they find that the detachment of layers in the vdWH is triggered by the growth of large bubbles. This study provides insights into the frictional dynamics and interfacial fracture of vdWH.
