Digital molds-- looking beyond 3D printing: Benjamin Peters at TEDxBeaconStreet

A digitally controlled, re-configurable mold is a device often seen in science fiction. Like the common pin art toy, a digital mold is made up of a dense array of parallel, moving pins and can quickly generate any desired surface shape. Realizing the potential benefits such a device could have for manufacturing and prototyping, Ben has developed technology that makes a low cost, high resolution, digital mold a reality.
Benjamin Peters is a PhD candidate in MIT's Mechanical Engineering department focused on developing new digital fabrication technologies to enable low cost, scalable manufacturing.
In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
