Dog With 3D-Printed Legs Gets an Upgrade (gizmag.com)
An anonymous reader writes with this update about Derby who was born with a congenital deformity that deprived him of front paws and was outfitted with a pair of 3-D-printed prosthetics. According to Gizmag: "You might remember Derby, a dog who was born with a congenital deformity but last year received a 3D-printed prostheses that enabled him to run for the first time. Well, it's onward and upward for Derby and his carers, who have now crafted an upgraded set of custom prostheses allowing him to walk proudly with a straight back and even sit like a healthy dog."
While it would still be good to know if, or what level of, pain the limbs cause... the demeanor of the dog seems to imply it's either minimal or outweighed by the freedom gained.
Yeah, but who would want to wear them? Your $40 legs made of 2x4 might be cheap, but I bet they're uncomfortable. These 3d printed legs are custom fit.
like custom fit grips for tools that can be done very cheaply by squeezing the right kind of silicone caulk in place with oiled rubber gloves
I've read around on this, and done some experimenting with casting with silicone. I haven't tried it yet, but supposedly you can squirt it into a bucket of water, then pick it up and mold it like putty for a few minutes and it will rapidly soft-set, then cure in the usual time or less. Oh yeah, and "the right kind" is the cheap kind that says on the container that it releases acetic acid when it cures, and not "Silicone II" etc. It moisture-cures, hence the bucket of water.
What I'm missing right now is an effective thinner for that stuff. I'd really like to use it in some applications where I need it to flow out more.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
If not, who made this decision, and what qualified this individual to do so?
The dogs owner made the decision, and he is qualified because he isn't an animal torturer like you who enjoys seeing living things in agony.
Sincerely, fuck you.
These don't seem to work as well as the short legs. It's looks like they take more effort, and his top speed is reduced. The moment arms are too long for his shoulder muscles.
