<mark>hygrophilic:</mark> preferring moist habitats<br>
<mark>Catalan surface:</mark> spiral-looking surface all of whose planes are parallel to a fixed plane<br>
<mark>geodesic:</mark> applying the notion of a straight line to curved spaces, used to mean the shortest distance between two nodes on the Earth's surface <br>
<mark>Polylactic acid (PLA):</mark> biodegradable polyester typically made from corn starch, tapioca roots, or sugarcane. PLA has one of the highest bioplastic consumption volumes in the world<br>
<mark>Acrylonitrile butadiene styrene (ABS):</mark> thermoplastic polymer, is amorphous and doesn't have a true melting point, can be carninogenic at higher temperatures (~400 °C) <br>
<mark>Stereolithography:</mark> uses a laser beam to 3D print layer by layer from a liquid polymer that hardens on contact<br>
<mark>Continuous Liquid Interface Production (CLIP):</mark>photochemical process involving uncured resin, exposure to oxygen, and a light source - it is said to be very fast<br>

<h3>Print</h3>
<p>I returned to the same shape for this week's assigment, taking it a step further I designed (using Rhino) a dodecahedron illustrative of the fact that a cube can be constructed from its vertices (Steinhaus 1999). I used the Formalabs and 3DWOX to make models at different scales. The first couple of attempts were trying – not enough support, too little resin, excessive support, etc.</p>

<h3>Scan</h3>
<p>Scanning an object posed its own set of challenges. Sense didn't seem to respond particularly well to my attempts of scanning a bust or small objects (about the size of a handful or less). However it did scan a bottle of Goop soap nicely (inserting an extra "o" for good measure). My dodecahedron didn't pass the Sense size threshold, so I tried to capture the shape using 123D Catch which did not turn out particularly well either.</p>

<h3>Scan some more</h3>
<p>This 3D heat scan was created in a collaboration with James Penn, a wizard of sorts. The idea behind it was to draw on the visuals heat produces as well as to scan a feature that extends beyond what is visible to the naked eye. <br>
Our set-up included a stepper motor, two breadboards, an arduino, mystery electrical components, and a couple of glasses of whiskey.</p>
