New Applications for 3D Printing: Sanitation and Shelter
As discussed by Hannah Fearn on The Guardian, international aid organization Oxfam is already using 3D printing to replace parts and fittings for taps and British sanitation kits in Lebanon that otherwise must be shipped from overseas. By using this technology, Oxfam can fix minor issues quickly, and as the technology progresses, they "will be able to make larger and larger things."
Oxfam is also looking into 3D printers to print emergency shelters. Gilles Retsin, a designer working on printed housing explains how, "it might be possible to print something very quickly in an unexpected site without the need for shipping anything. We would transport a printer and then we would use the materials on the site, such as sand."
Indeed, according to Fearn, "as it takes just 24 hours to build a set of rooms using local materials fed into a printer, it may have a useful function as a way to quickly and cheaply build medium-term accommodation during the rebuilding process." Moreover, based on the cultural and religious needs of the community, designers can adapt the dimensions of the house for more cultural sensitivity in regards to housing needs and spatial layout.
However, Maggie Stephenson, adviser to the UN Habitat, warns development professions must be "aware that the pioneers of this technique, like the pioneers of any technique, are always the most enthusiastic about its potential."
