In a modern laboratory, technicians use an Ender 3D printer to create surgical guides based on detailed medical images. The angle focuses on a close-up of a kneecap being printed, showing the object in a 75% print and glued to the printing base. Several surgical guides already printed are visible in the background. The scene presents a detailed surgical setting, with screens showing 3D models of the guides and precise calculations for the surgical procedure. Surgeons watch intently, eyes wide open, as they study the manufacturing process of the surgical guides.
