“…The n values were less than 1, meaning that the inks were non‐Newtonian fluids. The higher value of τ 0 (yield stress) indicated that the formula revealed stronger mechanical strength and better ability of shape retention (Costakis, Rueschhoff, & Diaz‐Cano, ). The higher K value reflecting the viscosity of mixtures suggested that the mixture (“oil” or “oil‐IMO‐GG”) displayed poor extrudability as they could not be easily extruded out from nozzle tip during printing.…”

Cordyceps militaris is a fungus that has been used as a functional food in China because it contains many kinds of active components (such as cordycepin, polysaccharides, ergosterol, mannitol, etc.). Cordyceps flowers are dried and also available in powder form with poor rehydration behavior. Considering taste, mouthfeel and appearance of printed products, the optimal printing formulation (powder: water: isomaltose: oil = 10:10:3:1) was obtained through response surface methodology. The rheological properties of rehydrated powder were enhanced due to the lubricating action of oil and the moisture absorption by isomaltose, reducing the line breakage but still showed structural collapse. Fortunately, the disadvantages of the above formulation were overcome by the addition of 1% (w/w powder) gum. The new formulation (powder: water: isomaltose: oil: agar = 10:10:3:1:0.1) exhibited the best printing results and there was a little effect on cordycepin content through 3D printing technology. The effectiveness of this new formulation as a printing ink was confirmed by low‐field nuclear magnetic resonance, rheological and textural measurements. Practical applications Cordyceps flowers and isomaltose contain many functional factors. 3D printing technology has the ability to design an appealing appearance, and capability of producing variety of textures by manipulating the internal structure. The combination of the two provides consumers with rich functional factors while attracting consumers to increase their acceptability of Cordyceps flowers. This study provides new ideas for other variety of food printing materials and demonstrates the shape development of foods by 3D printing.

“…In general, advanced ceramic materials are categorized into (i) technical and (ii) functional ceramics. Several examples of technical ceramic materials include oxide‐based materials such as silica (SiO 2 ), alumina (Al 2 O 3 ), stabilized zirconia (ZrO 2 ), toughened Al 2 O 3 or ZrO 2 , hydroxyapatite (HA), tricalcium phosphate (TCP), and nonoxide‐based materials such as silicon carbide (SiC), silicon nitride (Si 3 N 4 ), aluminum nitride (AlN) and boron carbide (B 4 C) . Functional ceramics, on the other hand, cover a broader range of materials that include ferroelectric titanate‐based materials (e.g., BaTiO 3 and PbTiO 3 ), magnetic ferrite‐based materials (e.g., NiFe 2 O 4 and BaFe 12 O 19 ), superconductor materials (YBa 2 Cu 3 O 7 ), and other electroceramic materials .…”

Ceramic Robocasting: Recent Achievements, Potential, and Future Developments

Additive manufacturing (AM) of ceramic materials has attracted tremendous attention in recent years, due to its potential to fabricate suitable advanced ceramic structures for various engineering applications. Robocasting, a subset of ceramic AM, is an ideal technique for constructing fine and dense ceramic structures with geometrically complex morphology. With the freedom and convenience to deposit various materials within any 3D spatial position, ceramic robocasting opens up unlimited opportunities, which are otherwise hardly attainable from other AM techniques. Here, a summary of the recent progress on the fabrication of single and multi‐ceramic structures by robocasting is provided, as well as the prospects of achieving shapeable ceramic structures. The current challenges in ceramic robocasting and an outlook on its development, especially toward the fabrication of self‐shaping ceramic structures, are also discussed.

“…As opposed to the direct processes used primarily in the metals and polymers approaches, indirect methods of AM need to be employed for most ceramics due to their high temperatures of melting, and for many structural ceramics, their incongruently melting nature. 9 However, there are a few recent examples in literature on B 4 C and SiC 3-D printing through binder jetting 10 and direct-ink writing 11 techniques, indicating that the desire for AM of these materials is becoming more desirable to the ceramic industrial base. The green body shape is heated to decompose organic binders and filler and then subsequently densified using traditional ceramic sintering processes.…”

The goal of this work was to present results of mechanical characterization and ballistic investigation of 3-D printed alumina (Al 2 O 3 )-based armor plates, manufactured using two additive manufacturing-based methods: pressurized spray deposition (PSD) and direct ink write (DIW), to determine the maturity of these additive-based processes against the industry standard process. The DIW plates exhibited superior hardness, flexural strength, and density compared to the PSD plates, and in many respects, even eclipsed some of the properties of the commercial isopressed (IP) material. Plates (90 mm × 90 mm × 8 mm) of these composition were manufactured for ballistic analysis in accordance with established ballistic characterization procedures, using a 50.8-mm-thick Aluminum 6061 plate as backing and witness plates in the case of penetration or deformation. Six alumina plates were examined ballisitically (one shot per plate) against the 12.7 mm APM2 projectile (45.9 g) at an impact velocity of 840 m/second. The plates that were manufactured using the DIW method provided a higher impact resistance than the PSD method, however, both did not perform as well as the traditionally processed IP material, due to the presence of defects introduced due to the printing processes.
