3D PRINTING FOR SUSTAINABLE LOW-INCOME HOUSING IN SOUTH AFRICA: A CASE FOR THE URBAN POOR

ABSTRACT

This paper presents the findings of an assessment of the possible measures needed for the adoption of three-dimensional (3D) printing for sustainable low-income houses that can be beneficial to the urban poor. The study adopted a quantitative approach and answers were sought from construction professionals actively involved in a construction project in the country. The study revealed through factor analysis that 3D printing for sustainable low-income housing delivery in South Africa could be encouraged through effective promotion and training, government support, improvement of 3D printing technology, and affordability of the technology. The study contributes significantly to the body of knowledge as it reveals the possible measures for improving the adoption of 3D printing in housing delivery in South Africa—an aspect that has not gained significant attention in the fourth industrial revolution and housing delivery discourse in the country.
