“…Samples with low water content had high viscosity and dense internal aggregation. This type of dough was relatively less easy to extrude and shrined more easily after extrusion, causing the border to shrink and deform inward (Zhao et al, 2021). The sample with high water content had a lower viscosity, and it was not easy to deform inwardly.…”

The application of 3D printing in the food field has received a lot of attention, and 3D printing can be used to make food that is easy to chew. Steamed buns are a traditional Chinese food, and no one has yet used 3D printing to make easy‐to‐swallow buns. In this study, rice flour and yeast were added to flour to improve its printing properties and textural properties, the effects of water addition on these properties were also studied. According to the results of preliminary exploration, a response surface with chewiness and cohesiveness as the response values was designed. When the water content was 64%, the addition of rice flour was 25%, and the addition of yeast was 0.36%, the chewiness of the optimal solution was 4.941 N and cohesiveness was 0.66, which were considered acceptable. It provides a new idea for developing steamed buns that meet the needs of various groups of people. Novelty impact statement As a traditional Chinese food, the commercial value of steamed buns is gradually increasing. The steamed buns made by 3D printing were similar in shape to traditional steamed buns but smaller and easier to chew and swallow. It can be considered easy‐to‐swallow food. This study also provides new ideas for the development of easy‐to‐swallow foods.

“…So it is important to find out appropriate 3D printing parameters prior to use. Especially for orthodontic treatment, where precise medicine is much demanded, the fabrication that involves 3D printing should be carefully examined [ 39–42 ]. Herein, we captured the key parameters for the 3D printing of a resin mold using the LCD-SLA strategy, and thus successfully generated the polymeric dental mold ( Fig.…”

The malalignment of teeth is treated classically by metal braces with alloy wires, which has an unfavorable influence on the patients’ appearance during the treatment. Herein, a modern treatment was tried using clear polymeric aligners, which were fabricated by molding a film material on the three dimensional (3D) printed personalized dental models. The key parameters of photocurable 3D printing of dental models and the mechanical properties of the clear aligner film material were investigated. Following a series of 3D-printed personalized dental models and finite element analysis to predict and plan the fabrication and orthodontic processes, clear aligners were fabricated and applied in animal experiments to prove the efficacy and biocompatibility. A clinical treatment was finally carried out, which highlights the advantage of the clear aligners as an esthetic, compatible and efficient appliance.

“…Hybrid printing is one of the most attractive methods since it combines several advantages of different technologies. UV-DIW has a wide selection of ink materials, and the extrusion-based printing methods are adaptable to many filler-containing systems, including carbon fibers, silicon rubber, hydrogel [ 28 ] and even metal powders [ 29 ]. With the assistance of the six-degree freedom robot arm, the extrusion ink with suitable viscosity generates complex 3D structures instead of the regular additive manufacturing that only prints layer by layer [ 30 ].…”

Effects of Fumed Silica on Thixotropic Behavior and Processing Window by UV-Assisted Direct Ink Writing

2022

View full text Add to dashboard Cite

In this research, the effects of fumed silica (FS) on the Ultraviolet (UV)-ink rheological behavior and processing windows were discussed. Objects using different concentrations of FS inks were printed by the modified UV-Direct ink writing (DIW) printer. The function of fumed silica in the ink-based system has been verified, and the processing scope has been expended with a suitable amount of FS combined with the UV light. The results show that the combination of a suitable amount of FS with the UV-DIW system reaches fast and accurate printing with a larger processing window compared to the non-UV system. However, an excessively high concentration of FS will increase the yield stress of the ink, which also increases the requirement of extrusion unit and the die-swelling effects.
