Engineers at the University of Buffalo have 3D-printed a life-sized hand in minutes rather than six hours, like conventional methods.

Their method of choice was stereolithography, which they say produces 3D objects 10-50 times faster.

“Most of the 3D printing technologies we see today are extrusion and inkjet-based. To build a 3D object using these methods, you will need to first build a 2D planar layer in a pixel-by-pixel manner and then add multiple 2D layers to 3D. Our FLOAT technology is based on stereolithography printing, which deposits material through photo crosslinking of the resins in an entire 2D plane. So it is inherently faster than extrusion and inkjet-based methods,” co-lead author Ruogang Zhao, associate professor of biomedical engineering at...
