Researchers at the University of Johannesburg surveyed South African consumers to gauge their attitudes towards 3D-printed food, a market projected to reach US$7.1 billion by 2034. The study explored consumer awareness, health perceptions, and convenience factors related to this emerging technology.

• The global 3D-printed food market is estimated at US$437 million in 2024.
• Oluwafemi Adebo, Professor of Food Technology, and Nicole Cunningham, Associate Professor, led the study.
• The survey included 355 South African consumers aged 18-65, predominantly females aged 24 to 44, who were already familiar with 3D-printed food.
• Positive attitudes were strongly linked to the perceived convenience and health-related benefits of 3D-printed food, including waste reduction and nutritional customization.
