There are problems in 3d printing house that require unique solutions.
Here we are trying to provide some solutions to these problems.
Insulation - How we have to deal with insulation? Do we have to print insulation? What are the best insulating solutions?
Utility - We need water and electricity running in the walls, what are the best solutions?
Finishing - We can see layers of concrete in the final printed houses. How can we make it look smooth?
Safety And Code - We have to make sure that we are printing a safe house that will satisfy building codes.
Simulation - We need to run some simulations on designs, I am not sure if we have any open source software available to accept STL or GCODE files and give you some kind of report about the structure.
