Arboretum Mold

| 1 Comment

Graduate students Daniel Dean and Ryan Wurst worked on a project for the Minneapolis Arboretum called Underground Sound. This field of sonic flowers allows viewers to listen to the sounds of the earth via giant megaphones.

The mold for the megaphone was designed in Rhino and imported into Enroute as an .STL. We created all the toolpathing in EnRoute. The form was cut in pieces on the CNC router using a 1/2" wide by 3.5" tall ball nose bit. Because our router only has a 6" z-clearance, Daniel glued together panel board to be 3.5" deep and divided the megaphone up into various sections. Once cut, the sections were glued together to create the final form, which was then used as a mold for the fiberglass.
