All spools of filament start with raw plastic pellets, the most common being PLA (Polylactic Acid), a biopolymer made from plant materials such as corn, sugarcane or beets. Other materials ...

In some ways, corn plastic is clearly easier on the environment. Producing PLA uses 65 percent less energy than producing conventional plastics, according to an independent analysis commissioned ...

Every time they change filaments, they’ve got to purge the ... very clean — no cross-contamination with plastics other than PLA, no metal bits in the chopped-up plastic bits, and most ...

[Thomas Sanladerer] setup a simple experiment, using samples of three common types of filament, specifically PLA, PET-G and ASA. He stored the samples in three environments, on his desk ...
