University of Nottingham scientists working with pharmaceutical company GlaxoSmithKline (GSK) have conducted a study “3D Printing of Tablets Using Inkjet with UV Photoinitiation.” The study used a Dimatix Materials Printer DMP-2850, a machine prefered for lab work given the low volume 1.5ml cartridges. Batches of 25 pills were 3D printed using a specially formulated ink containing Ropinirole HCl, a medicine used for the treatment of restless legs syndrome (RLS) and Parkinson’s disease. Using this set-up, batches of 25 tablets with a 5mm diameter were produced. Total printing time was 1.5 hours or approximately 4 minutes per tablet. Curing time was an additional 7.5 minutes per batch. The researchers conclude that, “UV inkjet printing has been demonstrated as a platform to produce solid oral dosage forms for the first time.” Source: Inside 3D Printing News
