MIT News has published a series of groundbreaking articles on 3D imaging, covering innovations that range from whole-brain mapping to tactile 3D models. Researchers at the MIT Computer Science and Artificial Intelligence Laboratory (CSAIL) and other MIT labs are pushing the boundaries of what’s possible with three-dimensional visualization and printing.
TactStyle: 3D Modeling You Can Feel
Developed by CSAIL researchers, TactStyle uses image prompts to replicate both the visual appearance and tactile properties of 3D models. This system allows users to not only see a 3D object but also feel its texture, opening new possibilities for virtual reality and product design.
Thermochromorph: Images That Transform Through Heat
The Thermochromorph printmaking technique allows images to transition into each other through changes in temperature. This innovation, also from CSAIL, uses heat-sensitive materials to create dynamic prints that shift appearance based on environmental conditions.
3D Imaging of Whole Human Brain Hemispheres
Three innovations by an MIT-based team enable high-resolution, high-throughput imaging of human brain tissue at a full range of scales. This technology maps connectivity of neurons at single-cell resolution, providing unprecedented insights into brain structure and function.
New Sensor Uses MRI to Detect Light Deep in the Brain
Researchers have developed a sensor that uses MRI to detect light deep within the brain. This approach allows scientists to map how light spreads in opaque environments, with potential applications in optogenetics and brain imaging.
Better Nasal Swab for COVID-19 Testing
MIT spinout OPT Industries uses novel additive manufacturing systems to create intricately-designed nasal swabs for COVID-19 testing. The company’s 3D-printed swabs offer improved efficiency and comfort.
Live Imaging of Brain Function
A new live imaging method brings structure to mapping brain function. Scientists can now distinguish brain regions based on their activity and overlay information about their structural organization.
Objects That Change Color Like a Chameleon
CSAIL’s new reprogrammable ink uses light to change the color of objects. This technology mimics the color-changing abilities of chameleons, with potential applications in adaptive camouflage and dynamic displays.
Creating 3D Images with Regular Ink
MIT startup Lumii helps manufacturers replicate the visual effects of holograms on printed materials using standard ink. This innovation makes 3D imaging accessible for everyday products like packaging and security features.
RePaint: Reproducing Paintings with Deep Learning and 3D Printing
CSAIL’s RePaint system uses deep learning and 3D printing to faithfully recreate famous paintings. The system captures the texture and depth of original artworks, producing faithful reproductions.
Glasses-Free 3D Movies at Home
A CSAIL system converts 3D movies into a format that can be viewed without specialized glasses. This technology could bring immersive 3D entertainment to living rooms worldwide.
Larger Scale Glasses-Free 3D Displays
A prototype display enables viewers to watch 3D movies without glasses from any seat in a theater. This system uses a novel screen design to create a wide viewing zone.
Fab By Example: Custom Designs at Your Fingertips
CSAIL’s Fab By Example lets users quickly create thousands of custom designs for furniture, go-carts, and more. The system simplifies the design process, making 3D modeling accessible to non-experts.
Illuminating Neuron Activity in 3D
A new technique allows scientists to monitor the entire nervous system of a small worm in 3D. This method provides a comprehensive view of neural activity, advancing understanding of basic neural circuits.
The Physics of Curly Hair
Researchers developed the first detailed model for a 3D strand of curly hair. Understanding the physics behind hair curl could lead to new products in cosmetics and materials science.
3D Scanning with Your Smartphone
Startup Viztu Technologies developed commercial software that generated 3D models from 2D photos, before selling to a tech giant. This technology demonstrated the potential of smartphone-based 3D scanning.
