Digital Design & Fabrication

– A Case Study at Georgia Tech, 2014 Summer

Subject of Digital Fabrication – “Interior Design Panels”

Digital Design to Digital Fabrication – Any Problems?

Geometric Modeling for various interior panels

Make it!

Cannot make it even if it is visible:

- Not solid geometry (e.g. surface, line…)

- Too big, too thin, too much curved…

- Hardware/software limitations…

- Material issues…

3d Printing – a new way of digital fabrication

Why so many people say this is ground-shaking?

Preview – a 3ds Max Object

Preview – Result

This object is moving,

but cannot remove from outer object

Only 3d Printers can make

this kind of products.

There are no cuts or glues.

Any other exceptional ideas for

interior architecture design?

3d Printing – “How to” actually print?

1. Prepare your model using 3ds Max, SketchUP, Rhino, etc.

2. Export it to OBJ file

3. Simulate & convert it to g-code file using Simplify3D software

4. Print it using SD card memory
