Dalhousie's 3D printer open to the public

It's technology that's been around for decades And now it's becoming mainstream.

3D printers basically 'print out' objects: a material such as plastic is sprayed out, layer on layer, from a nozzle, according to a computer program's specifications.

The CBC's David Thurton visited Dalhousie University to get a look at their new printer that's open to the public.
