Researchers at the UCL School of Pharmacy, University College London have found a way to change the rate of dissolution within medication via a 3D printing method. Researchers used MakerBot's water- soluble filament, cut it into tiny pieces and mixed in acetaminophen. They then used the Filabot extruder to extrude a drug infused filament. With this filament they printed odd shaped pills and tested them to see what effect different shapes had on the speed at which they dissolved. What they concluded was that 3D printing allows for unique custom shapes not possible with traditional pill fabrication.
