The JD-1, originally designed for guitarist John Denner, is one of the most advanced SLS-printed prosthetic hands ever created. This pioneering prosthesis leverages SLS technology to emerge from the printer as a fully assembled object, eliminating the need for manual assembly and significantly reducing production time. After just a few minutes of post-print cleaning, the JD-1 is ready to accommodate internal electronic controllers or mechanisms, adaptable to each user's unique preferences
