The Meat of the Future : Consumer Attitudes Toward 3D-Printed Meat Based on the Technology Acceptance Model

A growing global population makes it increasingly difficult to supply the world with sustainably produced meat. One possible solution is to produce meat by 3D-printing different types of meat pastes. The aim of this study is to map the general attitudes toward 3D-printed meat and how these attitudes positively or negatively affect the future of the market. This has been done through a semi-systematic literature review of previous research in the field of 3D-printed meat, structured using the TAM (Technology Acceptance Model) framework. The results showed that external factors were found to have a significant impact on attitudes, where consumer perceptions are influenced by knowledge, age, gender, price, environmental concerns, and cultural values. The perceived usefulness of the technology lies mainly in its health benefits, sustainability, and potential for personalization, while barriers such as feelings of disgust, lack of information, and high costs reduce interest in its use. Previous exposure, social norms, and transparency in production also affect the willingness to try the product. The study concludes that increasing acceptance requires improved knowledge and clear communication about the benefits of the technology, lower prices, and continued development to improve aspects such as taste and appearance. Moreover, targeted communication is essential, as attitudes vary greatly across different consumer groups.
