 If you think printing a livable house in 24 hours – 365 livable homes in under a year– sounds too good to be true, that’s perfectly normal because 3D printing technology is evolving faster than we can fathom.  

On a more affordable note, Business Insider reports that ICON is capable of producing an economy-sized building, around 600 to 800 square feet, in 24 hours at the low price of $4,000. Leading professionals from ICON further highlight that while 3D printing in construction shows promise for cost reduction, the current savings are modest—around 10 to 30 percent compared to traditional methods. But actually even 30 percent is an impressive amount.
