Join me as I chat with Theodora Papavasiliou, a plastic surgery trainee in London, and co-founder of Stelth limited, a company using 3D printing technology to make personalised surgical equipment and models. Theodora tells us what goes on behind the doors of Stelth, from first realising the potential for using 3D printing in surgery, to manufacturing personalised equipment across Europe, and winning the Cutler’s Surgical Innovation prize 2020. We also hear about how she translates Da Vinci’s writings in her free time!
