An Investigation into the Role of 3D Printing in Residential Buildings (2025-10)¶

This study examines the potential of 3D printing to improve the energy efficiency of housing in hot arid climates such as the UAE. Using a case study of a typical Emirati residence, twenty-four wall configurations were simulated, varying by material (standard vs. sulfur concrete), thickness (4 cm, 8 cm, 10 cm), and insulation level (0%, 25%, 50%, 100%). Results show that eleven configurations met the U-value requirement, six achieved cooling loads below the benchmark, and twelve reduced overall energy use, with only four meeting all criteria simultaneously. Standard concrete proved more versatile across performance conditions, while sulfur concrete with full insulation achieved the lowest energy consumption, underscoring its potential as a sustainable material. These findings demonstrate the value of 3D printing in advancing the UAE’s green building standards and environmental goals, while offering practical strategies for delivering more energy-efficient housing in hot arid regions.
