Summary: Direct ink writing is a versatile bioprinting technology for fabricating soft models. In this study, a novel method was developed to evaluate the quality of printing by introducing two dimensionless indices that reflect the average width and width variation of extruded filaments. The method was applied to examine the influences of printing parameters on the quality of zigzag multi-layer models printed using different concentrations of Pluronic (R) F127 materials. The results demonstrate that the dual-index method can effectively expose the morphological differences of extrudates under altered printing conditions, providing a potential evaluation tool for the quality assessment of direct ink writing.

Summary: Recent advancements in computational design and 3D printing technology have allowed for the fabrication of polymer lattices that have a high strength-to-weight ratio and tailored mechanics. However, limitations with most commercial 3D printing platforms have only allowed for the construction of monolithic 3D lattices. This study demonstrates the use of embedded three-dimensional (EMB3D) printing to create multi-material polymer lattices, enabling the fabrication of a wide range of periodic and stochastic lattices with tailored mechanical responses by printing multiple materials with different mechanical properties.
