3-D Printed Plastic Could Replace Not-Very-Good Corrugated Iron Roofs In The Developing World
Tuesday, November 11, 2014
Corrugated iron is the default roof material in much of the developing world, and there are several reasons why it’s far from ideal. One, iron has tendency to rust and degrade. Two, it heats up like a griddle in warmer climates. And three, it’s not insulated: air and water seep in, because the bumpy covering doesn’t lie flat to walls.
A Harvard spin-off, Resilient Modular Systems has two solutions to the problem. The first involves using new types of materials for roofing, like 3-D printed plastic from waste bottles. The second is to modularize roofing, so that it’s adaptable and easily repaired. The idea is to build a Lego-like system of bricks that can made locally, using whatever is closest to hand.
