Five ways bioengineers want to use 3-D printing

Now that 3-D printing has made it easier to generate custom-made prosthetics, bioengineers are looking ahead at manufacturing actual cellular material. Such technology could be the basis for personalized biomedical devices; tissue-engineered skin, cartilage, and bone; or even working bladders. In new work, researchers review and consider the progress made in 3-D bioprinting and what might be possible in the decades — or years — ahead.
