Chameleon-Inspired Tech 3D Prints Multiple Colors From a Single Ink

Researchers at the Beckman Institute have created a method for 3D printing and modifying structural hues in the visible spectrum, ranging from deep blue to orange. During the printing process, the UV-assisted direct-ink-write 3D printing method may change the structural color to produce vivid and possibly more sustainable hues. A sustainable method for 3D printing different dynamic colors from a single ink was discovered by researchers, who were inspired by the color-changing properties of chameleons. According to Ying Diao, an associate professor of chemistry and chemical and biomolecular engineering at the University of Illinois Urbana-Champaign and a researcher at the Beckman Institute for Advanced Science and Technology, "We can modulate structural color on the fly to produce color gradients not possible before." Therefore, this discovery is a revolutionary one for sure. The Inspiration Behind the Discovery~ Nature's design principles come into play when a chameleon changes color from turquoise to pink to orange to green. The lizard's skin is being seamlessly and silently camouflaged to fit its surroundings by sophisticated nano-mechanics. A Northwestern University team has created a unique nanolaser that uses the same principle as chameleons to change hues, drawing inspiration from nature. The research may pave the way for developments in ultra-sensitive strain sensors, wearable photonic devices, and flexible optical displays for smartphones and televisions. This Work Is a Great Illustration of the Power of Collaboration ~ Here, Diao and his colleagues describe a UV-assisted direct-ink-write 3D printing method that can modify structural color while printing by adjusting the light to regulate the evaporative assembly of specifically engineered crosslinking polymers. The structural colors that are prevalent in many biological systems originate from nano-textured surfaces that obstruct visible light, in contrast to conventional colors, which are derived from chemical pigments or dyes that absorb light. Lead author and Diao Lab graduate student Sanghyun Jeon stated, "This makes them more vibrant and potentially more sustainable." In the visible wavelength region, from deep blue to orange, the researchers can synthesize structural colors. The study team utilizes a single ink and changes the printing process to obtain the color gradient, whereas an artist may use several different paints. "The research demonstrates the value of our collective experiences in learning from one another's triumphs and setbacks," stated coauthor Simon Rogers, an associate professor of chemical and biomolecular engineering. “The biggest challenge of the polymer synthesis is combining the precision required for the nanoscale assembly with the production of the large amounts of material necessary for the 3D-printing process,” said co-author Damien Guironnet, a professor of chemical and biomolecular engineering. The color spectrum that can be obtained with this technology, according to the researchers, is not very wide, but they are trying to increase it by finding out more about the dynamics of how the layers grow in this process. The team is also attempting to increase the process's industrial relevance because the existing approach is not ideal for printing in huge quantities.

The printer then starts building the object by laying down successive layers of material, such as plastic, metal, or even living cells. There are several different types of 3D printing technologies, including Fused Deposition Modeling (FDM), Stereolithography (SLA), and Selective Laser Sintering (SLS). Each technology uses a different method of building the object, but the end result is the same: a fully-formed, three-dimensional object. 3D printing has a wide range of applications, from prototyping and product development to manufacturing and even medical and dental applications. For example, in the medical field, 3D printing is used to create prosthetic limbs, dental implants, and even human organs. In manufacturing, it is used to create complex parts for airplanes, cars, and other machines. Despite its many benefits, 3D printing is not without its challenges. The cost of the technology and materials can be high, and the process can be time-consuming. Additionally, there are concerns about the environmental impact of 3D printing, as well as the potential for misuse, such as the creation of weapons or other dangerous objects. 3D printing is a revolutionary technology that has the potential to change the way we design and manufacture products. As advancements continue to be made in materials, software, and hardware, it is likely that 3D printing will become even more prevalent in a wide range of industries.

New method helps in the 3D print of glass objects

Soon, it will be possible to make very small optical components for complex computers, thanks to the ability of scientists to develop a way to 3D print objects using glass. Researchers from Karlsruhe Institute of Technology (KIT) in Germany developed a process using glass for additive manufacturing techniques, commonly known as 3D printing. They could achieve this with the process of Stereolithography which is a form of 3D printing used for creating models, prototypes, patterns and production parts in a layer by layer fashion using photopolymerisation, a process by which light causes chains of molecules to link, forming polymers. This is the first time that the variety of 3D-printing techniques have been used on glass. Earlier, it has been used on polymers or metals, but never on glass. The 3D-formed glass can be used, for instance, in data technology. The next plus one generation of computers will use light, which requires complicated processor structures. Researchers said that 3D technology could be used to make small, complex structures out of a large number of very small optical components of different orientations.

A ‘Broken’ Heart can be mended by 3D- Bioprinted Patch.

According to new research findings, a scarred heart tissue caused by a heart attack can be treated by a 3D- bioprinted patch. This research has been done by a team led by the University of Minnesota biomedical engineering researchers who have successfully come up with revolutionary 3D-bioprinted patch. Due to heart attack, a patient loses blood flow to the heart muscle which causes cells to die. Human bodies are not equipped to replace heart muscle cells thus damaged. At that place in heart, a scarred tissue is formed, which may cause further ailment. During this study, the researchers used laser-based 3D-bioprinting techniques. They incorporated stem cells which were taken from adult human heart cells. These cells grew on a matrix and started to beat in a dish synchronously in the lab. After this cell patch was incorporated on a mouse following an induced heart attack, the scientists found remarkable improvement in functional capacity after just a month, according to ‘University of Minnesota Twin Cities.’ As the patch was created from cells and structural proteins from the heart, it became part and parcel of the body. As such, no more surgeries were needed for the same ailment.
