Make a Scale Model: Folding Architecture

Interested in creating a scale model of your home or of a building? Well, you've come to the right place. I've developed a program that makes it intuitive to create a scale model of any structure.

Using my program's grid-based interface, you can map out a building in its "unfolded" form. Then, the program generates a 3D model by concatenating a base model in the same pattern created in the program. Next, print the file and fold it into your design!

To get started, decide on what you want to create a model of. I chose to design a model of my house.

To make the next step simpler, divide your design into smaller sections — consider making each room or hallway an individual model.

Then, think about how each piece will connect.

This is a simple preset I implemented into my program. When it is folded, it becomes a basic 3x3 cube. Using this logic, start drawing out each piece of your design into the program. When you are finished, export the 3D model by clicking generate STL.

I created this program using the Pygame library with Python.

Depending on the size of your 3D printer's bed, you may need to break up the design into multiple files. Import the STL file exported from the program into your preferred slicer. I used UltiMaker Cura for this project. In print settings, change infill type from cubic to concentric.

I've meticulously experimented on various parameters to allow for maximum flexibility and form retention. PLA Filament with concentric infill has shown the best results.

Additionally, if your prints have trouble sticking to your print bed, especially with these thin prints, consider adding a brim (Search Build Plate Adhesion Type).

Lastly, hit slice!

After you've acquired the G-code file from your slicer, send it to your printer.

An advantage of folding architecture is the filament cost. If you were to print the shape as desired, it would need support structures.

Initially, I set the base model to a thickness of 4mm; however, it was too thick. After a few trials, I landed on 0.8mm.

The base model I've created in Fusion 360 has a grid with a cell size of 100mm². The grid allows for clean folding at the ridges and a clear scale.

Finally, fold your designs precisely as intended. It should be quite easy to bend due to the thin PLA and grid pattern.

Congrats! You've made a scale model.
