Polylactic Acid is a compostable plastic that can be made from renewable resources — usually plants. Compared to ABS plastic, it’s much harder, warps much less, and can be crystal clear. When I first got my hands on some PLA filament in 2009, it had the potential to be my new favorite plastic…but getting it working took time.

It’s been over two years since I last posted anything substantive on the net.
