Key Barriers to 3D Printing Technology Adoption for Sustainable Project Delivery in Nigeria

Abstract

Adopting 3D printing technology has the potential for sustainable construction practices and mitigating environmental impacts. There are challenges to its adoption in developing countries. Hence, this study evaluates the barriers to adopting 3D printing technology in Nigeria. A post-positivist philosophical approach guided a quantitative research methodology towards a questionnaire survey. The population comprises stakeholders who focus on 3D printing technologies and are involved in sustainable development. Using snowball sampling, 380 questionnaires were distributed online; 253 copies were retrieved, screened, and analysed using descriptive and inferential analysis. The mean scores range from 3.09 to 3.46, with key barriers such as limited technical expertise, inadequate regulatory frameworks, and cultural resistance. The Kruskal-Wallis H test outcome revealed that the respondents’ opinions differed significantly for the variables since their p-values were less than 0.05. It is recommended that there is a need to enhance awareness of 3D printing technology through workshops, seminars, and demonstration projects that engage construction professionals and industry stakeholders. The study suggests developing technical skills through vocational training programs and certifications for a robust 3D printing workforce.
