If we invest in 3D Printing technology, we can provide our people with decent housing fast and end informality.


Johannesburg, South Africa (31 May 2022) – Tshilidzi Marwala – the Vice-Chancellor and Principal at the University of Johannesburg – shared an incredible video of a 6-bedroom house being 3D printed in just one day!

Unlike most other industries, the construction industry has not changed significantly in the twenty-first century: the processes and materials have remained essentially the same. And, bricks-and-mortar construction continues to monopolise the industry. As a result of this fixation, many valuable benefits that it might otherwise have enjoyed are lost to the industry. A general reluctance by the construction industry to embrace technological advancement has meant that productivity is tedious, outdated and lacking in dynamism and creativity.

Students at the University of Johannesburg (UJ) believe that the construction industry is well-positioned to: refine its business-as-usual productivity and efficiency models; and embrace technological advances such as Building Information Modeling, 3D printing and augmented reality.

3D-printing technology was developed in 1980 by Charles W Hull. Hull patented the first commercial 3D printer or stereolithographic machine in 1986. This machine functioned by having several layers of liquid UV-cured resin, one on top of the other, and then using a UV laser to trace and solidify a pattern, which in turn caused each successive layer to adhere to the previous layer.

Marwala explained in a series of tweets that the 3D Printer at UJ is fast.

“If we invest in this technology, we can provide our people with decent housing fast and end informality.”

Hopefully, we will get another update today but check out the posts below:
