Though the price of a 3D printed house can vary significantly based on various factors, the short answer to this question is: Yes, 3D printed houses are cheaper. Using 3D printing technology as your building method can save costs in different domains, like labor hours, material usage, indirect costs, and certain steps from the traditional construction process that are omitted. 3D printed houses are, however, generally only cheaper when they are designed as a 3D printed house from the beginning. This way, you can make sure you enjoy optimal material usage and timelines.
