Summary: Carbon-fiber-reinforced polyetherimide (CFRP) is an advanced composite material with excellent properties, but drilling it is challenging due to its complex structure. This study shows that rotary ultrasonic-assisted drilling can effectively reduce cutting force, surface roughness, and torque in CFRP composites. The use of diamond-impregnated hollow tools in this drilling process can minimize microcracks and fiber delamination, making it suitable for various industrial applications. Overall, rotary ultrasonic-assisted drilling is a promising technique for CFRP composite machining. (c) 2022 Elsevier Ltd. All rights reserved.

Summary: Rotary ultrasonic machining (RUM) is an effective method for processing difficult-to-cut materials, but the understanding of critical cutting force in RUM system with frequency-tracking module is lacking. This study models the dependency of ultrasonic amplitude on cutting force and develops experimental methods to measure the actual ultrasonic amplitude and critical cutting force. The experimental results validate the models and analyze the influence of electrical and mechanical design on critical cutting force in frequency-tracked RUM system.

Summary: This study investigates the electrical characteristics of the ultrasonic vibration unit in a rotary ultrasonic machining (RUM) system. The relationship between electrical parameters and the resonant frequency of the ultrasonic vibration unit is studied when different tools are clamped. Rotary ultrasonic drilling experiments are conducted to study the effect of processing parameters on the electrical characteristics of the ultrasonic vibration unit. It is found that the variations of electrical parameters are significant under different ultrasonic voltages but not under different feed rates.

Summary: Titanium and its alloys have excellent properties, but their relatively low hardness and wear resistance limit their service life in high-performance applications. The fabrication of a ceramic reinforced titanium matrix composite coating can enhance microhardness and wear resistance. Ultrasonic vibration can reduce TiC aggregation, decrease porosity, reduce defects in the bonding interface, and increase mechanical properties.

Summary: This study examined the compressive properties of AM fabricated CFRP composites with different fiber contents, finding that increasing fiber content slightly reduces compressive strength and modulus while increasing ductility and toughness. Among the fiber contents studied, 20% carbon fiber content provided the most decent compressive properties. AM fabricated composites generally exhibit higher compressive properties than tensile properties due to their higher plastic deformation ability observed in compression loaded parts.

Summary: Shell printing is an advantageous technique that prints a thin shell of the object to enclose loose powder. This study investigated the powder packing in the shell and core for the first time. The density and microstructure of the printed samples showed differences in powder packing between the shell and core, influenced by powder particle size and layer thickness. By selecting the proper layer thickness and powder particle size, shell printing could be a promising method to tailor density and reduce anisotropy.

Summary: The objective of this study was to evaluate the feasibility of producing metal-free fully ceramic composites using binder jetting of alumina preforms and spontaneous infiltration by copper in air. Different particle sizes of alumina powders were used as feedstock for binder jetting, followed by standard post-processing steps. The sintered specimens were then infiltrated with copper, resulting in improved mechanical properties compared to the porous sintered specimens. The compressive strength of 826.0 MPa and flexural strength of 317.5 MPa achieved in this study exceed those reported in the literature for binder jetting and/or infiltration of alumina-based specimens.

Summary: Process variables such as extrusion pressure, nozzle size, and bioink composition can affect the shape fidelity and cell viability of bioprinted constructs. Increasing extrusion pressure or decreasing nozzle size decreases cell viability, but smaller nozzle size is necessary for higher shape fidelity and higher extrusion pressure is needed for smaller nozzle diameter. An optimal combination of variables for shape fidelity and cell viability must be determined for specific bioink compositions. This study investigates the effects of extrusion pressure, nozzle size, and bioink composition on shape fidelity and cell viability using photo-crosslinking and alginate-methylcellulose-GelMA bioink with algae cells.
