B4 - Term project

For this term project Nana and I will look into how 3D printing of houses can be a part of the sustainable development in the building industry. We will have a special focus on how the building technology of a 3D printed house is compared to a traditional masonry house. The 3D printed houses we have looked at is built of one massive wall which have made us think of how the heat and moist is transferred through the wall is and what consequences it will have for the building. In many articles it is written that 3D printing of houses can be more sustainable because of less material used and it is faster to build the house, but if heat is transferred through the wall and moist damages the house it will not be more sustainable because more energy will be used in the operation stage of the house. We have earlier work with life cycle assessments and will therefore look at the project with that perspective.

Aaron Goldberg: It really sounds like an exciting project. I like that you are looking at the 3D-printing with an critical perspective of the construction and that you compare it with the traditional manufacturing. I think it is very important to look at the 3D printing with a life cycle perspective and consider all the process and consequences of it.
