摘　　要：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 m^(2)(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 7.39×10^(4) kg CO_(2) eq,9.34 ×10^(4) kg CO_(2) eq,and 3.82×10^(4) kg CO_(2) eq respectively.
