The company Printed Nest is looking to bring birds back to the urban setting with the release of its 3D-printed bird feeders. The 3D-printed feeders are made from Polylactic acid, which is a biodegradable plastic, and they are small enough that they can be affixed to a window in an urban setting, even if there is little space available. The design itself is open-sourced and available for users to print their own bird feeder if they already own a 3D printer, rather than ordering one directly from the company. The feeder can then be customized by changing the color or geometry to suit your taste.
Currently the majority of the printers made are located in cities throughout Europe, but there are several popping up throughout the rest of the world as well. The company asks all new users to log the location of their feeder once they begin using Printed Nest, with the hope that the use of their design will help popularize 3D printed bird feeders customized specifically to fit the ever-changing urban environment.
