====== The Bukobot 8 Green ====== By using renewable and biodegradable plastics (PLA), Bukobot 8 Green is a friend of the environment. Not only does the lack of heating platform required with other plastics reduce energy costs on Bukobot 8 Green, but the parts that it prints and the parts that its made of are easy to recycle. PLA is also a stiffer plastic than ABS, which is perfect for mechanical parts. And, in the process of printing the cornstarch-based PLA, Bukobot makes a sweet popcorn smell to please your nose.
