“…The apparent viscosity behavior of the mixtures showed a reduction in viscosity compared to pure ABS concerning shear rate (as shown in Figure 4), similar to the findings of Calafel et al 45 and Smirnov et al 46 This indicates that the mixtures exhibit viscoelastic fluid properties and can be extruded through a finer nozzle under appropriate printing pressure without clogging, meeting the requirements of 3D printing 47 . One contributing factor is the presence of stearic acid or carnauba wax (acting as a surfactant/dispersant), as mentioned by Hnatkova et al 48 and Gorjan et al, 49 and demonstrated in the work of Faccio et al, 26 in which the presence of stearic acid decreased the viscosity, increasing the fluidity of mixtures of ABS with alumina.…”

The development of functional compounds for extrusion applied in the additive manufacturing of anthropomorphic simulators is interesting, as it guarantees the manufacture of a 3D model similar to the patient. These simulators find applications in therapies or laboratory tests involving x‐rays. In order to replicate human conditions in these tests, it is essential to create materials that closely match the properties of human tissue, including the smoothness of soft tissues and the hardness of the bone tissue. This study developed ceramic‐polymeric composites, where the tomography intensity of each mixture was measured experimentally. Combinations of acrylonitrile butadiene styrene (ABS) with zirconium oxide and basic bismuth carbonate allowed imitation of bone tissue. The samples containing zirconium oxide and basic bismuth carbonate presented results that exceeded the minimum limit and reached a value close to 2000 Hounsfield units (HU) with 12% basic bismuth carbonate content. Combinations of ABS with hydroxyapatite and aluminum oxide can imitate soft tissues. The use of a surfactant facilitated the mixing of ceramic filler with polymer. Finally, 3D printing of a physical model was performed using a dual extruder printer, allowing simultaneous printing of bone and soft tissue components.Highlights Material mimicking x‐ray attenuation similar to bone tissue.

“…Some of the limiting factors of FFF ceramics are related to geometrical defects and minimum feature size, as well as the need for prolonged thermal cycles to prevent defects, such as cracks and blisters, resulting from trapped pyrolysis products. The available literature on ceramics produced with FFF is mostly focused on the production stages of both alumina and zirconia parts and their mechanical properties [27][28][29][30]. To address these challenges, extensive research has been conducted on filament composition and preparation [31,32].…”

A novel approach for manufacturing porous materials, foreseen as solar receivers for concentrated sun radiation, used in the power tower technology is presented. In such applications, materials are subjected to steep thermal gradients and thousands of cycles. Yet, materials consisting of honeycombs and ceramic foams showed insufficient thermal performance. By using the fused filament fabrication process, one can design printed parts meeting the requirements for solar receivers, namely dark color and high solar absorptance. This exploratory study unveils data on the retained crushing strength of newly developed 3D-printed porous Black Zirconia cubes after thermal cycling under similar conditions to those experienced by volumetric receivers and catalyst substrates for solar fuels (H2 and/or CO) production via the thermochemical cycle. Unlike dense ceramics, the resistance to thermal shock of 3D-printed cubes underwent a gradual decrease with the increase in the thermal gradient. The thermal shock cycles were performed between 800 °C and 1100, 1200, and 1300 °C, corresponding to a ΔT of 300, 400, and 500 K, respectively. Additionally, water quenching tests were performed at ΔT = 300 K up to 400 K. Crushing strength measurements carried out to evaluate the retained mechanical strength after exposure up to 100 cycles showed that the Black Zirconia cubes can withstand thermal gradients up to at least 400 K.
