3D printing technologies have evolved at an incredible rate, from 3D printed meat and 3D printed houses to 3D printed guns.
Many 3D printers have bragged about being the future of printed organs, but we haven’t gotten there yet. Now a new study on the Perhaps the key to 3D printed organs is the University of Buffalo.
“The technology we have developed is 10 to 50 times faster than the industry standard, and it works with large sample sizes that were very difficult to achieve before,” the co-lead author said in a statement. study Ruogang Zhao, Ph. D., associate professor of biomedical engineering.
The researchers released a seven-second video that is sped up from 19 minutes and shows one full hand being printed at a time. This process would normally require at least six hours using conventional 3D printing methods.
The new method is called stereolithography and uses gelatinous materials called hydrogels.
“Our method allows rapid printing of hydrogel models the size of a centimeter. This dramatically reduces part warping and cell injury from prolonged exposure to environmental stresses that you commonly see in conventional 3D printing methods, ”added study co-lead author Chi Zhou. , Ph.D., associate professor of industry and systems. engineering.
Scientists also claim that the method is particularly suitable for printing cells with integrated blood vessel networks. This type of technology is expected to be a central part of the production of 3D printed human tissues and organs.
The work was funded by the National Institute of Biomedical Imaging and Bioengineering at the National Institutes of Health. UB’s School of Engineering and Applied Sciences and the Jacobs School of Medicine and Biomedical Sciences provided additional funding. The study was published in the journal Advanced health materials.
