“…Therefore, rightly, their manufacturing with the DIW technique has attracted considerable attention. In the literature, structural integrity issues in relation to MXene-based inks have been reported [106]. Specifically, the necessity of using a great amount of MXene material in order for the ink to have certain rheological properties for 3D printing is the main challenge that needs to be overcome [107,108].…”

Three-dimensional printed electrodes seem to overcome many structural and operational limitations compared to ones fabricated with conventional methods. Compared to other 3D printing techniques, direct ink writing (DIW), as a sub-category of extrusion-based 3D printing techniques, allows for easier fabrication, the utilization of various materials, and high flexibility in electrode architectures with low costs. Despite the conveniences in fabrication procedures that are facilitated by DIW, what qualifies an ink as 3D printable has become challenging to discern. Probing rheological ink properties such as viscoelastic moduli and yield stress appears to be a promising approach to determine 3D printability. Yet, issues arise regarding standardization protocols. It is essential for the ink filament to be extruded easily and continuously to maintain dimensional accuracy, even after post-processing methods related to electrode fabrication. Additives frequently present in the inks need to be removed, and this procedure affects the electrical and electrochemical properties of the 3D-printed electrodes. In this context, the aim of the current review was to analyze various energy devices, highlighting the type of inks synthesized and their measured rheological properties. This review fills a gap in the existing literature. Thus, according to the inks that have been formulated, we identified two categories of DIW electrode architectures that have been manufactured: supported and free-standing architectures.

“…Subsequent curing, often through processes like sintering, solidifies the metal particles, layer-by-layer, to form the desired 3D object. This technology enables the creation of intricate and customized metal components with a high level of precision, making it suitable for various applications, including prototyping and functional part production [48][49][50][51][52][53][54]. However, parts produced with this technology have high porosity and insufficient cohesion between layers [54].…”

Fused filament fabrication (FFF) is an extrusion-based additive manufacturing (AM) technology mostly used to produce thermoplastic parts. However, producing metallic or ceramic parts by FFF is also a sintered-based AM process. FFF for metallic parts can be divided into five steps: (1) raw material selection and feedstock mixture (including palletization), (2) filament production (extrusion), (3) production of AM components using the filament extrusion process, (4) debinding, and (5) sintering. These steps are interrelated, where the parameters interact with the others and have a key role in the integrity and quality of the final metallic parts. FFF can produce high-accuracy and complex metallic parts, potentially revolutionizing the manufacturing industry and taking AM components to a new level. In the FFF technology for metallic materials, material compatibility, production quality, and cost-effectiveness are the challenges to overcome to make it more competitive compared to other AM technologies, like the laser processes. This review provides a comprehensive overview of the recent developments in FFF for metallic materials, including the metals and binders used, the challenges faced, potential applications, and the impact of FFF on the manufacturing (prototyping and end parts), design freedom, customization, sustainability, supply chain, among others.

“…It is therefore well-suited for the flexible design and fabrication of organ models with different physicochemical and biological properties. [29] Despite the numerous advantages of DIW, some challenges still need to be addressed for its application to bioprinting 3D organ models. The technology still faces limitations when producing intricate and precise geometries, and the printed constructs with voids or channels are prone to deformation and collapse.…”

Abstract3D bioprinting enables the fabrication of human organ models that can be used for various fields of biomedical research, including oncology and infection biology. An important challenge, however, remains the generation of vascularized, perfusable 3D models that closely simulate natural physiology. Here, a novel direct ink writing (DIW) approach is described that can produce vascularized organ models without using sacrificial materials during fabrication. The high resolution of the method allows the one‐step generation of various sophisticated hollow geometries. This sacrificial‐free DIW (SF‐DIW) approach is used to fabricate hepatic metastasis models of various cancer types and different formats for investigating the cytostatic activity of anti‐cancer drugs. To this end, the models are incorporated into a newly developed perfusion system with integrated micropumps and an agar casting step that improves the physiological features of the bioprinted tissues. It is shown that the hepatic environment of the tumor models is capable of activating a prodrug, which inhibits breast cancer growth. This versatile SF‐DIW approach is able to fabricate complicated perfusable constructs or microfluidic chips in a straightforward and cost‐efficient manner. It can also be easily adapted to other cell types for generating vascularized organ tissues or cancer models that may support the development of new therapeutics.
