The double-dose cup designed by DD Studio using Eastman TritanTM copolyester is composed of individual pieces that create a functional medical cup when assembled. The attributes of toughness, clarity, and chemical resistance of the polyester make it suitable for the design and development of intricate, complex medical devices, while the design flexibility and ease of processing work for prototype development.
During creation of the double-dose cup prototype, DD Studio determined that the copolyester worked for cold swaging, a joining technique that offers unique possibilities to part designers and fabricators. The method involves bending and crimping a plastic part without heat to join two parts, which can save energy and avoid the use of chemicals, adhesives, and mechanical fasteners.
