“…The unique fracture behavior exhibited by the as‐prepared high‐precision honeycomb Si 3 N 4 ceramics also allowed us to prepare large‐scale honeycomb sandwich ceramics in the future. The compressive strengths of other state‐of‐the‐art 3D‐printed honeycomb and lattice ceramics are summarized in Figure 4d 4,40–48 . It can be proved that the preparation of Si 3 N 4 honeycomb ceramics in this work has relatively excellent mechanical properties, and this research will further simplify the preparation process of honeycomb Si 3 N 4 ceramics and greatly reduce the manufacturing cost.…”

In this paper, a honeycomb Si3N4 ceramic was fabricated by 3D printing with a well‐preserved structure. The effects of Si3N4 content on the rheological properties of Si3N4/sol–silica ink and the printing resolution of products were investigated. The microstructure, phase composition, liner shrinkage rate, and fracture behavior of printed samples before and after sintering were systematically characterized in detail. The results showed that the modified inks had the optimized rheological properties, and the stress–shear rate curves corresponding to each slurry could be well described by Bingham and Herschel–Bulkley fluid models. The corresponding slump rates of the printed samples with different Si3N4 to sol–silica mass ratios were all lower than 4%, and the linear shrinkage rate of all of the samples after sintering was below 20%. The fracture behavior under compressive loading of the honeycomb Si3N4 ceramics tended to be non‐catastrophic fractures both before and after sintering. The compressive strengths of all of the printed samples decreased with the increase of the Si3N4 content, and the highest compressive strength of the honeycomb ceramics could reach 131.2 MPa after sintering at 1600°C, which was about 366.9% higher than that of the samples in green state prior to the sintering.

Integration of 3D Printing–Coelectrospinning: Concept Shifting in Biomedical Applications

Porous structures with sizes between the submicrometer and nanometer scales can be produced using efficient and adaptable electrospinning technology. However, to approximate desirable structures, the construction lacks mechanical sophistication and conformance and requires three-dimensional solitary or multifunctional structures. The diversity of high-performance polymers and blends has enabled the creation of several porous structural conformations for applications in advanced materials science, particularly in biomedicine. Two promising technologies can be combined, such as electrospinning with 3D printing or additive manufacturing, thereby providing a straightforward yet flexible technique for digitally controlled shape-morphing fabrication. The hierarchical integration of configurations is used to imprint complex shapes and patterns onto mesostructured, stimulus-responsive electrospun fabrics. This technique controls the internal stresses caused by the swelling/contraction mismatch in the in-plane and interlayer regions, which, in turn, controls the morphological characteristics of the electrospun membranes. Major innovations in 3D printing, along with additive manufacturing, have led to the production of materials and scaffold systems for tactile and wearable sensors, filtration structures, sensors for structural health monitoring, tissue engineering, biomedical scaffolds, and optical patterning. This review discusses the synergy between 3D printing and electrospinning as a constituent of specific microfabrication methods for quick structural prototypes that are expected to advance into next-generation constructs. Furthermore, individual techniques, their process parameters, and how the fabricated novel structures are applied holistically in the biomedical field have never been discussed in the literature. In summary, this review offers novel insights into the use of electrospinning and 3D printing as well as their integration for cutting-edge applications in the biomedical field.

The choice of resin for ceramic stereolithographic 3D printing has a critical impact on printed ceramic preforms. In this study, we focused on the correlation between resin composition and parameters such as cure depth, surface morphology, lateral dimension, apparent layer height, and surface roughness. Special emphasis was placed on the addition of an oligomer and a plasticizing agent to a monomer‐based suspension. Four suspensions were studied: a 100% monomer (ethoxylated trimethylolpropane triacrylate) only suspension (M100), a suspension with 25% by weight plasticizing agent (polyethylene glycol) (PEG25), and two different suspensions with oligomer (urethane methacrylate) added at 25% (O25) and 50% (O50) by weight. Constant energy and printing parameters were used between suspensions. Adding a plasticizing agent (PEG25) was found to increase the cure depth and projected image of the samples, while additional oligomer with both amounts (O25 and O50) resulted in a decrease in the same parameters. The suspensions with oligomer were found to have increased surface roughness measured using the average deviation from the profile height mean line (Ra), with O25 at 13.47 µm and O50 at 11.47 µm. All suspensions had negative values of skewness (Rsk) in the range –0.4 to –1.2. PEG25 had the surface most distinct from a normally distributed surface with an Rsk of –1.12 and a kurtosis (Rku) value of 4.49. The use of the average length of a profile element (RSm) as a layer height estimation tool was explored and it was found that the RSm was within 10 µm of the printed layer height in all suspensions studied except for PEG25. This study highlights the importance of resin composition in ceramic stereolithographic 3D printing. Modulating the inclusion of a plasticizing agent and oligomer in the resin has significant effects on printed sample parameters such as cure depth and surface roughness.
