Printability Metrics in Direct Ink Writing: Critical Review of the Literature and Novel Perspective Based on Dimensional Analysis

open access: yesAdvanced Materials Technologies, EarlyView.
The impossibility of defining universal printability criteria for Direct Ink Writing (DIW) requires “unpacking” the process into printing subfunctions. Each of these is rationalized by identifying dimensionless groups, allowing effective comparison between the various material‐ and process‐related parameters for printability purposes.

Understanding and Circumventing Failure Mechanisms in Chalcogenide Optical Phase Change Material Ge2Sb2Se4Te

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
Chalcogenide optical PCMs have gathered interest for their potential in compact, non‐volatile optics and photonics. Free‐space PCM metasurfaces require new considerations from phase change memory that need to be addressed for reliable scale‐up. Several failure mechanisms pertaining to free‐space PCM devices and layout methods are isolated to prevent ...
