3-D Science

With a name like "replicator", one might imagine that the odd, box-shaped device sitting in ICTP's Science Dissemination Unit's (SDU) laboratory was a low-tech version of the matter converters used by the intrepid crew of the Starship Enterprise.

However, reaching that part of the technological universe may take a few more years.  The "replicator " at ICTP is a three-dimensional printer that can make solid objects out of plastic. Using a digital model, the printer creates the objects layer by layer with a molten liquid plastic.

At a seminar today (24 October), SDU's Carlo Fonda introduced this new technology to the ICTP community. SDU has created the innovative, low-cost EyA automated recording system for classrooms, so it follows that they would be interested in new technologies that could enhance science education.

After presenting an overview of the development and costs of 3-D printers (they are getting cheaper, which is good news for early adopters who may want to purchase one of their own), Fonda talked about the uses, which range from art to prosthetics to humanitarian projects in the developing world. "Students can print out molecules to discover their complex structures," explained Fonda.

Fonda believes that 3-D printing has the capability to popularize and democratize science. "I would like to bring a 3-D printer to Africa," said Fonda, who has travelled extensively through the continent to teach hands-on courses on wireless networking and other topics.
