The advancement of 3D-printed wall technology represents a significant innovation in the construction industry, particularly in the housing sector. This technology is increasingly being discussed due to its potential to reduce construction project time and address the growing demand for affordable housing. Despite its benefits, the widespread adoption of 3D printed wall technology faces significant challenges, primarily due to the high initial costs associated with expensive 3D printing equipment and materials. This study aims to identify the main challenges and strategies for implementing 3D-printed walls in affordable housing projects. A quantitative approach was employed, involving 73 housing developers in Selangor. Data were collected through online questionnaires and physical meetings, achieving a response rate of 71.2%. Frequency and descriptive analyses were conducted to address the study's objectives. The analysis revealed that transportation is the primary challenge in implementing 3D-printed walls for affordable housing. Additionally, the main strategy for successful implementation identified was ensuring worker safety. These findings suggest that addressing transportation logistics and prioritizing worker safety are crucial for improving the adoption of 3D-printed wall technology in affordable housing projects. In short, the relationship to the construction sector is multifaceted, involving technological advancement, economic considerations, implementation challenges, safety concerns, and data-driven strategies. Integrating 3D-printed wall technology in the construction sector, particularly for affordable housing, can revolutionize building practices by improving efficiency, reducing costs, and meeting the growing demand for housing.
