So this week we made good progress, and we are headed in the right direction with creating a thermochromic iPhone case. The original research we did had us convinced that we should buy separate plastic to adhere to the iPhone case, but after deeper research we found that there is thermochromic 3D printer filament ink! This simplifies the iPhone case because now we are able to create a case and the color changing effect in one piece, rather than sticking them together. Thermochromic filament is difficult to come by, but the three sources we have found are, respectively, in China (Suntec from http://www.aliexpress.com/item/Factory-direct-sale-Blue1-75-3-0MM-Luminescent-PLA-filament-for-3D-printer-For-Makerbot-Reprap/1819140844.html), the Netherlands (Trideus from http://www.trideus.be/en/formfutura-thermochromic-ecopla-grey.html), and the US (Makerbot from https://store.makerbot.com/filament/pla#small). We decided to order from Markerbot, since they are closest and a well known brand. We purchased a small spool of "Blue Photochromatic" filament . We are excited to print a test case and see if it works!
Until next week,
Etienne
