Scientists have achieved a significant breakthrough by developing the world’s first 3D-printed brain tissue that mimics natural brain behaviour. This innovation holds great promise for advancing research into neurological and neurodevelopmental disorders like Alzheimer’s and Parkinson’s disease.

How it was made?

• Unlike traditional methods, the scientists employed a unique approach, stacking layers horizontally and using a softer “bio-ink” gel to support brain cells.
• The resulting tissue allows neurons to grow and communicate with each other effectively.
• This breakthrough could revolutionize stem cell biology, neuroscience, and our understanding of various brain disorders.

3D printing technology is also revolutionizing the future of multiple industries. It works by adding layers of material on top of each other. 3D printed objects prevent the waste of excess materials and are faster and cheaper to produce.3D printing is possible with the help of 3D in computing. A computer-generated graphic that provides the perception of depth similar to a real-world object. Computer-aided design (CAD) and computer-generated images (CGI) using computer technology to create 3D images. These images can also be printed with 3D printing. 3D printers are able to produce high quality three-dimensional objects such as prosthetic legs, and human organs.

Industries of all types benefit from 3D technology, including real estate, architecture, healthcare, automotive, aeronautics, research and retail. This technology is commonly used in movies, video games, graphics and virtual reality (VR) projects like the metaverse.

The process of creating a 3D image depends on the type of graphic, how it will be deployed and what 3D modelling software will be used to create it. Both CAD and CGI use the following two steps to create 3D images:

1. A computer-generated 3D model of a physical object provides a mathematical representation of the object, serving as a blueprint for producing the final image. Designers use various techniques with these models. A common technique is non-uniform rational B-spline, which provides mathematical representations of curve and surface geometries, including standard shapes, such as cubes or pyramids. A newer approach to modelling is digital sculpting, also called 3D sculpting. Digital sculpting providing tools that help make manipulating digital forms a more organic process.
2.  After a model has been completed, rendering is applied to create a realistic image that integrates effects such as lighting, shadow, reflections, textures, materials and other details to make the image as photorealistic as possible.

Rendering can be done in advance or in real time. For example, rendering done in advance might be used for a website’s graphics or a motion picture, whereas real-time rendering might be used for gaming or an interactive product catalogue.
