Summary: This article focuses on analyzing the morphology of polyelectrolyte-based layer-by-layer (LbL) films created using a direct ink writing (u-DIW) approach. The results show that the extent of polyelectrolyte interdiffusion within the films is limited in the case of the u-DIW approach, causing the formation of thinner films compared to traditional dip-coating. Compared to dip-coating, u-DIW enables the formation of homogeneous films with equivalent properties while using significantly less material. The fundamental analyses presented in this article will likely facilitate the application of LbL in various fields.

Summary: This work proposes a novel method for designing lightweight infill structures based on polyhedral cells for 3D printing. The method determines the parameters of the parametric polyhedral cell through stress optimization to achieve self-supporting, specified filling rate, and wall thickness. The optimization of the cell's number, centroid, and thickness improves the fabrication of overhanging inner surfaces and enhances the mechanical properties of the printed products. The proposed method uses simple geometric shapes for the infill structure's cross-sections, making it easy to fabricate.
