3D Scanning and Printing Assignment Week of February 24, 2014: The goals for the week are to design an object and 3D print it, and 3D scan an object. Directions include "keep it small" which I appreciate. My intent is to model the villi of the small intestine.
1. Shawn pointed me in the direction of Tinkercad and, after watching a Youtube tutorial on the basics of Tinkercad, I employed the cube and paraboloid shapes to fashion four villi. I also found a pdf http://www.3dvinci.net/PDFs/GettingStartedInTinkercad.pdf which I believe will be very useful for my 7th grade students. 2. I used the hole tool and Group command to created a space within each villus. Here is the finished Tinkercad product:
3. On to the Haystack Fab Lab - I pulled up my design, created and downloaded the STL, opened it with Makerware, hit "Make"and brought the card and the information across the room to the 3D printer.	4. The resolution of the model was too fine, the wall thicknesses were too small for the the printer to resolve at the tips of the villi. However, I was still thrilled with my first attempt.
5. Without a 3D scanner at the Haystack Fab Lab, I began to explore 123D Catch online. I took 20 pictures of my frog object, uploaded them and waited. Although I am intrigued by the process, my frog object was still processing after 36 hours.	6. There was a cranium in the object file at 123D Catch. I created an stl file of that. It's a start toward understanding, and I certainly know much more than I did a week ago. Mickie Flores Home
