At Nicklaus Children’s Hospital in Miami, the Cardiovascular Surgery Advanced Projects Laboratory (APL) uses a range of digital 3D technologies, including Stratasys® 3D printers, to visualize anatomy and plan surgical procedures for pediatric patients. A previous case study featured Nicklaus Children’s application of 3D printing to help repair a child’s heart, showing the great potential using of anatomical models in clinical settings. The latest Nicklaus Children’s success story involves planning a life-saving operation for Roy, an 8-year-old boy with a difficult-to-treat tumour.
