University of Glasgow Researches 3D Printed Medicine
Every family has some kind of home remedy for the common cold or flu. My mom’s was the standard chicken noodle soup and 7-Up. I’ve heard other folks talk about their parents feeding them far stranger things when they were sick, including a spoonful of garlic followed by a shot of whiskey. 3D printers may eventually make all these “remedies” obsolete, by allowing people to print their own medicines at home.
A University of Glasgow research team has made steps toward using 3D printers as home chemical fabricators. The team used a 3D printer and open source CAD software to create vessels for chemical reactions made from a polymer gel. The gel sets at room temperature, creating what the researchers have dubbed “reactionware.”
By adding other chemicals to the gel as it is printed, the team is able to make the vessel part of the reaction process, something not usually seen outside of industrial chemical engineering. This could allow for the process to be replicated in small labs or even at home. This is the sort of democratization of manufacturing that is the ideal for the future of additive manufacturing (AM).
“It’s long been possible to have lab materials custom-made to include windows or electrodes, for example, but it’s been expensive and time-consuming,” says Professor Lee Cronin, Gardiner Chair of Chemistry. “We can fabricate these reactionware vessels using a 3D printer in a relatively short time. Even the most complicated vessels we’ve built have only taken a few hours.”
“By making the vessel itself part of the reaction process, the distinction between the reactor and the reaction becomes very hazy,” added Cronin. “It’s a new way for chemists to think, and it gives us very specific control over reactions because we can continually refine the design of our vessels as required.”
While Cronin and his team admit their research into this new application of 3D printing is still in the very early stages of development, Cronin has a vision for the future of medicine that very nearly eliminates the need for drugstores and could bring badly needed drugs to anyplace with AM capabilities.
We could even see 3D printers reach into homes and become fabricators of domestic items, including medications. Perhaps with the introduction of carefully-controlled software ‘apps,’ similar to the ones available from Apple, we could see consumers have access to a personal drug designer they could use at home to create the medication they need. –Professor Lee Cronin
The team has written a paper on their research which was published in Nature Chemistry.
