I just saw MakerBot’s blog post saying they finally got in a batch of MakerBot approved PLA.  This is supposed to be nigh magical stuff.  It prints at a cooler temperature than ABS, it has a low shrinkage factor meaning it won’t warp much if at all, it will stick to blue masking/drafter’s tape not requiring the use of an acrylic build platform, and it’s very clear.

While I was at it, I also ordered an extra brass nozzle, brass barrel, PTFE insulator, ceramic tape, nichrome wire, thermistor, and I asked for some MakerBot stickers to adorn my laptop.  :)
