Abstract

This paper presents a comparative “cradle to gate” life cycle assessment (LCA) of 3D printing houses and conventional buildings using SimaPro software, as a tool to model and compare the two alternatives. The study considered a terraced type of buildings with a floor area of 60 m2 (functional unit), which could occupy 2-3 households. The results indicated that 3D printing houses have a smaller environmental impact than conventional buildings in all impact categories except in terrestrial ecotoxicity, in which both alternatives resulted in 172 kg 1,4-DB eq. 3D printing houses exhibit a higher climate impact from Timber floorboards, window frames, and Portland cement which are responsible for 7.39 ´ 104 kg CO2 eq, 9.34 ´ 104 kg CO2 eq, and 3.82 ´ 104 kg CO2 eq respectively.
