One of the main goals of 3D printing and medicine is to be able to 3D print human organs for implantation. People all over the world are waiting for transplant lists because the number of available organs is so low. A group of researchers from the University of Buffalo has created a new, high-speed 3D printing technology that they believe moves medicine one step closer to 3D printed organs.
Engineers They shared a short video of their process as they create a 3D printed hand. The video lasts seven seconds and is said to be “faster than 19 minutes”. While the video makes it seem as if the print process takes only seconds, it took 19 minutes to produce. Keep in mind, however, that 3D printing such a detailed model of the human hand with other systems could take up to six hours.
The scientists on the project say the technology they’ve developed is 10 to 50 times faster than industry standards and works at large sample sizes. The ability of a 3D printing system to operate at large sample sizes is something that has been difficult to achieve in the past. The project uses a 3D printing technique called stereolithography and hydrogels. Hydrogel is a gel-like substance used to make a wide variety of products.
Researchers from the University of Buffalo have devised a method for rapidly printing centimeter-sized hydrogel models. The team say their process significantly reduces the component deformation and cell injury caused by prolonged exposure to environmental stresses seen in typical 3D printing processes. The new method is particularly suitable for printing cells with compact vascular networks, which is critical for 3D printed human tissues and organs.
