A while ago, we had a fan duct melt on one of our Replicator 2's. We (Eric) recently printed a replacement, but in PLA. It worked fine for a few days, but ended up causing quite a mess.
Here are a couple of prints we tried.
We've talked about prosthetic devices before, but e-Nable recently put out a challenge for the community to print 1000 hands by the end of October. We talk a bit about the e-Nable hand and another group based out of Fargo (Protosthetics). Their arm, called PAL (Printed Artificial Limb), uses Mio electronics and even has an elbow.
At the end of the show, Jake wanted to talk about PaperCube's 3D printed articulated rhino. Amaochan has been featured on Thingiverse twice and can also be found on Facebook (mostly in Chinese).
Don't forget to follow Fargo 3D Printing for further updates.
