Hello! The devices were printed with Eco-ABS. I would have printed with PLA; however, the MMC guides suggested the use of ABS, which I’m guessing is due to durability. Eco-ABS is just a more environmentally-friendly version of ABS.
We unfortunately cannot provide any legal type information on whether it is “safe” or should be used for specific purposes – as we are a high-school robotics team and are doing this on a volunteer basis to help others. I apologize for the inconvenience.
