“…Direct writing denotes a group of techniques used to precisely deposit a variety of materials onto a substrate in digitally defined locations [84] and among them inkjet printing, laser printing and in general all the layered-based methods have shown remarkable potential for the fabrication of modern products. The application of these techniques to the fabrication of LIBs requires the development of ink-like mixtures of the electrode materials with proper colloidal properties in order to make them compatible with the printing machines.…”

“…This is one trade-off between expensive and complex processes and ease of patterning. Moreover, direct patterning techniques are usually limited in terms of the three-dimensional structure that can be formed because the material is "printed" from a source onto the substrate [18].…”

The aim of this work was to develop a novel hybrid manufacturing method for nanoscale three-dimensional (3D) printing with multi-material capabilities. 3D structuring methods at the micro/nanoscale are major goals of various engineering fields, and much work has been carried out to improve the minimum feature size, geometrical complexity, and material selection. With the aim of nanoscale multimaterial printing, a hybrid process was reported with an integrated nanoparticle deposition system (NPDS) and focused ion beam (FIB) system; however this process has limitations in terms of surface roughness and control over the layer thickness, as well as with the process scale, and furthermore, lack of sacrificial layers.In this dissertation, a novel hybrid process is described, which combines aerodynamically focused nanoparticle (AFN) printing, micro-machining and focused ion beam (FIB) milling. AFN printing is based on NPDS, and micromachining was used for local planarization. In addition to these processes, spincoating was used to fabricate sacrificial layers. By bridging these different II micro/nanoscale processes, the resulting hybrid process can address the limitations of the individual processes.To create the hybrid process, each process was investigated to enable compatibility. With the AFN printing system, the surface morphology of a detached substrate was observed, and the bonding mechanism between the substrate and nanoparticles was investigated. A novel printing strategy was identified to reduce the scale of the process. With the micro-machining system, different tool geometries were investigated. Complex geometries inspired by conventional-scale tools were implemented on the micro-scale, and their effects were investigated. With the FIB system, material re-deposition phenomena were investigated to reduce defects that occur during ion sputtering. A novel path-generation strategy was identified and investigated for different scanning paths.Process capability is discussed using fabrication examples and functional applications. The novel hybrid process represents a significant advance in the state of the art, and enables far improved process scales or dimensional degree of freedom, without losing the advantages of broad choice of materials.3D-pinted micro bi-material cantilevers were fabricated as a thermal actuator.The mechanical and thermal properties of the structure were investigated using an in-situ measurement system, and irregular thermal phenomena were analyzed. It is expected that these in-situ measurements of the 3D printed microstructure will contribute to materials research.Various 3D structures can be fabricated using the process described here from a range of metal/ceramic inorganic materials, including polymers. In particular, it is expected that the process will contribute to the area of customized nanoscale structuring, with potential applications in medical treatments. It is also expected that this work will contribute to further improvements in manufacturing technology by combining different m...

“…It has been rise to be an automated system that prints the cell-laden bioinks with a high resolution, accuracy, and precision [17] . As the lasers is beamed on the absorbing layer, the bioink is deposited in micro-sizes by controlling scanning mirrors and focusing lens in x and y-axis ( ) [18][19][20][21] . This nozzle-free fabrication prevents cell o r material clogging often found in extrusion-based 3D cell printing techniques [16] .…”

Three-dimensional (3D) printing in tissue engineering has been studied for the bio mimicry of the structures of human tissues and organs. Now it is being applied to 3D cell printing, which can position cells and biomaterials, such as growth factors, at desired positions in the 3D space. However, there are some challenges of 3D cell printing, such as cell damage during the printing process and the inability to produce a porous 3D shape owing to the embedding of cells in the hydrogel-based printing ink, which should be biocompatible, biodegradable, and non-toxic, etc. Therefore, researchers have been studying ways to balance or enhance the post-print cell viability and the print-ability of 3D cell printing technologies by accommodating several mechanical, electrical, and chemical based systems. In this mini-review, several common 3D cell printing methods and their modified applications are introduced for overcoming deficiencies of the cell printing process.
