Summary: Roller micro imprinting process is an effective method for fabricating large-area micro features with great accuracy and efficiency. The forming behavior of micro square dimple arrays in roll-to-plate micro imprinting process was investigated through experiments and simulations. The cross section profiles of the formed micro square features in rolling and transverse directions were found to be significantly different, indicating uneven plastic flow in the two directions. The grain size of the material also influenced the forming process.

Summary: Roll-to-roll nanoimprint lithography (RTR-NIL) is a low-cost and continuous fabrication process for large-area functional films, but the filling process of UV resin obstructs the production. This study proposes a multiphase numerical model using a sliding mesh method to demonstrate the actual behavior of imprint mold rotation and UV resin filling on PET substrate. The numerical model gives better insights into the filling process for mass production of functional surfaces on an industrial scale.

Summary: High-volume manufacturing of microstructures is crucial for commercial utilization and large-scale experimental research. Polydimethyl siloxane (PDMS) is widely used in academia for microfluidic test devices. This study demonstrates a reduced ambient pressure roll-to-roll imprinting process using PDMS, significantly reducing the number of bubble-induced defects in microstructures.

Summary: Rolling ceramic thermal insulation balls, with advantages of low cost and easy control of particle size, are likely to become the main raw material for 3D printing, but research on their thermal insulation properties is lacking. This study analyzed the effects of temperature, particle size, and thermal fatigue on the thermal conductivity of aluminum oxide balls, and found that the contact area between particles played a dominant role in heat transfer process. Increasing contact area significantly increased thermal conductivity, while reducing surface contact area and increasing porosity could decrease thermal conductivity of the materials.

Summary: Metallic additive manufacturing techniques have limitations in designing macro/mesoscale functional structures, while electrohydrodynamic printing technology has the potential to precisely fabricate micro/nanoscale metallic structures with revolutionary and versatile capabilities. This article reviews the latest developments and applications of metallic electrohydrodynamic printing for micro/nanoscale functional architectures. The basic principles, process parameters, and characteristics of metallic inks for micro/nanoscale electrohydrodynamic printing are analyzed. The unique capabilities of micro/nanoscale metallic electrohydrodynamic printing in fabricating minuscule 3D electronic structures, high-resolution multimaterial architectures, high-performance sensing structures, and multi-functional optoelectronic components are highlighted. Finally, the challenges and future perspectives of translating micro/nanoscale electrohydrodynamic printing into a mature AM technology for the fabrication of 3D functional metallic architectures are discussed.

Summary: With the rapid development of MEMS, micro/nanoscale fabrication of 3D metallic structures with complex structures and multifunctions is becoming increasingly important. Micro/nanoforming, as a promising micromanufacturing approach, has advantages but is far from being well-established, and is currently a hot research topic.

Summary: The glass forming ability of alloys is closely related to the full-width at half-maximum of the first diffraction peak in the X-ray diffraction pattern, providing guidance for the discovery of bulk metallic glasses. Through experimental and computational methods, it has been revealed that the glass forming ability of an alloy is mainly characterized by its amorphous structure. A strong correlation has been found between high glass forming ability and a large dispersion of structural units in the amorphous structure.
