3D Printed House From Revit

This is a one story home with a basement, designed in Revit, these steps will also work with a project with 2 or more stories. This Project will allow for the different stories of your design, including your roof, to nest nicely together instead of sitting loosely on top of eachother.

Once I exported these files as STL files, I printed the individual sections on a Stratasys F170 Printer using ABS filament. The purpose of this project is to allow you to see inside your house, through doors and windows, as well as from the top down.

In this section, you will prepare the roof for 3D printing. This will include drawing walls attached to the roof which will act like a ledge to nest it into the first floor.
