Some people might wonder why I am printing Mixtape Mendel in black. For those of you that are wondering, or might otherwise not be, I did it primarily as means of easier comparison. Currently my Isaac uses 3mm filament. Mixtape is going to be using 1.75. Right now there is only black and natural 1.75mm PLA on the market. Black nicely shows defects, or print quality. My rational is that I will be able to compare results of these two printers easily due to the photogenic nature of black over natural PLA.
