3D Printing and Scanning

For 3D Printing, I used 123D Design from Autodesk to design the object to print out. I sent the STL file to 3dprint@cba.mit.edu on Friday for weekend 3D prints.

The printout was successful! Even though the top circular parts were separated from the upside-down pyramid shape.

I scanned a small sculpture I received in Egypt from a friend. I downloaded 123D Catch from Autodesk on my Android phone and took pictures of the object as instructed by the application. I had to try taking pictures multiple times because the capturing process was sensitive to fuzziness and lighting of the photos. Below are the front view picture of the Egyptian head sculpture on the left and the image file of the generated 3D scanned object on the right. I was satisfied with the result because it did a pretty good job picking up the details of the face and the necklace. Below is the picture of the head sculpture and the scanned 3D model of it. The scanned geometry was hollow inside and had multiple cracks and holes.

I exported the scanned head into Autodesk Meshmixer for editing the model. 123D system automatically stores the projects into their cloud system and it was very convenient to import the file into Meshmixer. I used Transform, Align, Plane Cut, Make Solid and Discard functions to revise the model. I did not feel the tool was very complicated and easy to use for beginners. The final version looks like below.
