With over 50% of the world’s population living in cities, urbanization is transforming how we live and build. The pressing need for affordable housing and the scarcity of construction space in urban areas call for innovative solutions; one promising solution is 3D construction printing technology.

By 2030, the UN predicts that around 3 billion people worldwide will be affected by the affordable housing crisis. This urgent demand of homes calls for innovative solutions in the construction industry to make affordable housing a reality for everyone. Canada has now taken the first step toward that goal by investing into innovative construction solutions.

Construction is famously slow to embrace new technology, and 3D printing is no exception, held back by strict regulations like fire safety standards despite its potential to transform how fast we build. So how does the industry clear the way?

Two technologies are reshaping how we build: robotic arms and gantry 3D construction printers. Here’s how they compare, and what each one does best.

3D printing has spread from medicine to aerospace, but few industries have gained as much as construction, where it’s reshaping the way we build from the ground up.

Sustainable building design cuts environmental impact and conserves resources, and 3D construction printing (3DCP) opens a whole new way to approach it. These are the 4 key principles behind it, and what they mean for a greener construction industry.
