These days, you can 3D print just about anything, but one hobbyist claims that his functional grand piano is the world’s first to be 3D-printed. It’s reportedly fully 3D-printed aside from the screws, pins, and felt sheets, complete with playable keys using accurate action mechanics as well as functional pedals. Instead of guitar or piano strings, rods are used instead since 3D printing plastic material is not strong enough to handle the total string tension.
It was printed on a Prusa Mk3s and a Prusa MINI+ using five different type of filament, including Esun White PLA+, Esun Beige PLA+, Prusament Viva La Bronze as well as the Eryone Silk Copper PLA. There are a total of 24 keys and the reason why there isn’t 88 keys is to keep the dimension within a specific envelope to ensure a minimum number of split parts that can be printed on the Prusa MINI+ bed size of 180x180mm.
