3D Scanning & Printing
This week we learned 3D scanning and printing, the mission is to design and 3D print an object that could not be made subtractively, and 3D scan an object and print it.
Scan and Print a Jiabao
Make Sense of 3D
I first used the Sense 3D scanner. It is light, portable, and fast. With a chair being my turn table and a tripod to hold the Sense high, I scanned myself. It does not work very well with hairs. The complexity of hairstyles makes the 3D model complex and large. I should've cut to bald beforehand.

Clean up supporting materials
Add my upcoming AR hat
I am the TA of Krzysztof Wodiczko's Public Projection class this semester. We let the students create a performance or an installation that engages with a specific statue.
To teach them how to project map to the face of the sculpture and to have a miniature version of the sculpture at hand for testing, I decided to use this 3D scan - print - MadMapper 3D object mapping pipeline to teach the students.
Wesley Buskirk has a very good tutorial on this here.
Design a digital 3d object (.obj file)
- Generate UV coordinates
- 3D print your digital object
- Setup your video projector
- Position your printed object and your projector
- Load the 3D object into MadMapper
- Calibrate the 3d object to the projector
- Fine tune
- Live Lighting
- MADLines / Animated lines
Matter and Form
To better understand the limitations of 3D scanner, I scanned my iron gauge hat. This time I tried the matter and form scanner. It has a turn table on itself.
The iron gauge is very reflective and has holes in the mesh.
Two hours of scanning

Tangible Human Desire
Eye tracking data visualization
The huge data set of eye tracking have shown people's particular interest towards face and certain body parts. I'm wondering if this human desire would be tangible, how it feels like if I can hold it.
So I made the eye tracking data of the image above into a 3D visualization, and try to 3D print it.

Some tests around the hat.
I always want to try projection from a drone. So I printed the mount to hold the projector. Its quality will be tested next week.
Projector to be mounted on DJI.
Ninja Flex, for my wearable experiment.
Design the foldable structure for my AR lenses
Formlab's Supporting material is always more beautiful than the actual prints..
After 4 iterations, it finally arrives at the right angle and the right length!
