All work and no PLA makes Zheng a dull boy

I’m headed off to Maker Faire Detroit in a few hours, and I needed a new Penny Ballista to take on the crew from MakerBot in a no-models-barred Seej match. So I personalized the nock on this one and gave it a go printing with PLA.

The Replicator can print in (at least) two kinds of plastic: ABS, which is the stuff LEGO bricks are made of, and PLA, which is a biodegradable wonder plastic made from corn.

PLA works better than ABS at lower printing temperatures. I’ve been lowering the extruder by 1° every time I print something new, and still haven’t found the floor.

This is my first set of prints with PLA, and I like what I’ve seen so far. I bought this roll from JetJet2004 on Amazon a couple of weeks ago, and I haven’t been disappointed with it yet.

I also printed some Seej Bloxen, Riveted, which aren’t available on Thingiverse: if you want one, you’ll have to solve the
Cryptstone Challenge.

So! Find me walking around with a ballista in my pocket at Maker Faire Detroit on Saturday. I’ll be the pale geek in cargo shorts and a t-shirt.

What do you think?
