3D printed pills point to personalised medicine

Led by Nottingham University, the new technique enables the printing of multiple drugs in a single tablet.

Researchers from the University’s Centre for Additive Manufacturing and School of Pharmacy fabricated personalised medicine using Multi-Material InkJet 3D Printing (MM-IJ3DP). The research is detailed in Materials Today Advances.

The team has developed a method that enables the fabrication of customised pharmaceutical tablets with tailored drug release profiles, ensuring more precise and effective treatment options for patients.

This is made possible by a novel ink formulation based on molecules that are sensitive to ultraviolet light. When printed, these molecules form a water-soluble structure.

The drug release rate is controlled by the interior structure of the tablet, allowing for timing the dosage release. This method can print multiple drugs in a single tablet, allowing for complex medication regimens to be simplified into a single dose.

In a statement, research lead Dr Yinfeng He, Assistant Professor in the Faculty of Engineering’s Centre for Additive Manufacturing, said: “This is an exciting step forwards in the development of personalised medication. This breakthrough not only highlights the potential of 3D printing in revolutionising drug delivery but also opens up new avenues for the development of next-generation personalised medicines.”
