3D PRINTING AND SCANNING

3d Printing - Rheotomic Surface



For this assignment, I wanted to make a geometry that would be nearly impossible to fabricate without the 3D printing technology. As a result, I designed a rheotomic surface. To generate this geometry (which is actually a complex mathematical function), I drew a curve, extruded it up, and twisted that extrusion. I then trimmed the edges of the surface so that it has a square footprint. Then I mirrored the surface across its edges to create a single complexe rheotomic surface. After that, I thought i should add more complexity and test the level of resolution of the ABS 3d printer and the rigidity of the material. As a result, I scripted the holes onto the surface. After it was printed, the base geometry was maintained with the resolution and the material was quite rigid despite the holes and thinness of the model. However, there were some instances around the holes where the resolution was not high enough and as a result there were some excess materials hanging onto the edges.

3d Scanning - Headphones and Laura:

I started by scanning something (*I thought*) would be simple - some headphones. I started by opening the ZScan program. Then I configured the scanner by getting the meters within their desired ranges. After that, I calibrated the scanner using the X panel. Then I scanned the positionign features. Then I started to scan the headphones. I found that some of the reflective metal elements on the headphones would not properly scan.





After that, I thought it would be fun to scan a person using the alternate method of placing the positioning dots on the subject. I configured, calibrated, and then scanned. I found that some features of the face would not scan such as the eye brows, eye lashes, and the lips. I assume the lips were more difficult to scan due to their reflectiveness (like the metal features of the headphones). However, the eyebrows confuse me, maybe they are too complex (?).
