“…Ink materials used by direct write printing are typically formulated and designed to rapidly solidify after exiting the nozzle tip. [13,21,35] Figure 1a and b represent desired rheological properties of ink used for direct ink printing, which was formulated by Lewis and coworkers. Various building block materials can be used for direct write printing ranging from ceramics, polymers, to composites.…”

Three-dimensional printing of multi-material parts relies upon efficient mixing of the ink components and a rapid response to composition changes. However, at low Reynolds numbers and large Peclet numbers, mixing disparate viscosity and density inks poses a challenge. In this study, the performance of active micromixers for disparate non-Newtonian inks is evaluated using both This article is protected by copyright.

Using detailed simulation results, multiple factors are identified that can impact the micromixer response time during a composition change. Lastly, an active micromixer is proposed and evaluated to efficiently mix arbitrary multi-material ink compositions and produce fine composition gradients within printed parts.

and environmentally friendly conductive cables or wires as a replacement for copper. From this view, carbon-based nanomaterial is a potential candidate.Carbon related nanomaterials including fullerenes, carbon nanotubes (CNTs), and graphene are promising due to their exceptional conductive and electronic transport properties, which may accelerate the practical and potential applications for various kinds of novel engineering areas spanning from electronics, energy storage, and advanced materials to nanotechnology and biotechnology. Among the family of carbon nanomaterials, CNTs have been a particularly attractive material since its discovery in 1991 by Iijima, [1] due to their nanoscale 1D shape, excellent mechanical properties, tunable electrical properties either metallic or semiconducting, high current carrying capacity, and many other exciting properties. These properties have highlighted the potential of CNTs use in a plethora of applications, including electrically conductive fillers in polymer composites, flexible and transparent conductive films, microelectronics (transistors, interconnectors, heat dissipaters), and lightweight conducting wires and cables. [2] Figure 1 points out the forecast presented by Endo et al. [3] on the present, near future, and long term applications of CNTs in various fields. An interesting potential application of CNTs is the long-term electrical conductors, which are able to transmit power from plants to plants or households, as well as be used in electronic devices.Compared to conventional copper cables or wires, CNT based cables have several advantages including 1) a lower density of 1.3 g cm −3 for single-walled carbon nanotubes (SWCNTs) [4] and 2.1 g cm −3 for multiwalled carbon nanotubes (MWCNTs), [5] both of which are much lower than that of copper, 8.96 g cm −3 ; [6] 2) environmental stability, which can stand with severe conditions including high pressure, large temperature changes, etc.; 3) excellent mechanical performance with a Young's modulus and strength in the ranges of 1.0 TPa and 50 GPa, respectively; [7] 4) ultrahigh electrical conductivity as high as 10 8 S m −1 for SWCNTs, which is higher than that of copper (≈10 7 S m −1 )). [8] Furthermore, the limited amount of conventional conductive metal resources in nature and their soaring market price greatly increased the need for a desirable alternative solution that are abundant in nature, low-cost, andThe lack of progress to obtain commercially available large-scale production of continuous carbon nanotube (CNT) fibers has provided the motivation for researchers to develop high-performance bulk CNT assemblies that could more effectively transfer the superb mechanical, electrical, and other excellent properties of individual CNTs. These wire-like bulk assemblies of CNTs have demonstrated the potential for being used as electrical conductors to replace conventional conductive materials, such as copper and aluminum. CNT conductors are extremely lightweight, corrosive-resistive, and mechanically strong while being ...
