With the idea that eventually the photon could be connected with 3D printed parts especially conductive filament. Could someone, ( @peekay123 @ScruffR ) have a look at this issue on the raise3D forum..
Basically we are trying to anneal conductive filament to reduce it's resistance. So far a small 1 cm strip embedded in regular PLA has a resistance of about 2000 ohms.
By heating the PLA to about 110 Degrees Celcius and slowly cooling it, I managed to reduce the resistance by 600 ohms. Just wondering if we could use electricity to heat the conductive filament. Any suggestions?
I am thinking 30 V DC but not really sure for how long to heat about 3 grams of Conductive PLA (0.13 W / m K Thermal Conductivity). Any ideas or safety concerns?
