Here's the paper
http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=6678531

Looks quite doable. Though I still like the Delta design best (I'll have to research this).

... and Julia said someone had tried welding and had failed... oh well, this field is starting to move real fast. If we don't do what we want, we'll just follow in someone else's footsteps (not a bad thing just not as exciting).

Going through the doc, I notice the most expensive part is the welder. So if someone has one of those to donate (per his price list) this becomes a $300 project.

Anyone want to give up a dusty welder? :)

They're using a simple (though nice) 120v mig welder that you can find for far less than the retail price they quote. My hobart 140 (same exact welder, different color) was < $300 new. You'll need something with gas hookups which excludes only the cheapest horrible freight stuff. You'll spend as much in supplies and parts as you did on the welder, if not more.

Anyone know someone at airgas or Roberts oxygen? If one was going to be built I'm sure we could convince them to sponsor it or at least donate materials for it. It'd be fantastic PR for them.

there are no pictures of their printed parts. i have seen this article, and am looking at 'lost pla' instead.

Looks like "lost pla" gives a much nicer finish, at least today.  Looking forward to see what happens, though - if the technology improves at anything like the rate of plastic FDM, it is going to be interesting to watch.  I have been hanging onto the materials to make a Gingery-style forge, to try it out - I was really impressed with the results from this (http://3dtopo.com/lostPLA/) guy, and would love to replicate.  Does anybody have any experience with the process?

Thanks!
-Mark

"Wire-fed welding torch lays down a bead of titanium"

Wonder if this is done within an inert gas environment. Doesn't titanium instantly oxidize when you weld it in an oxygen-rich environment?

IDK why they didn't mention the possible engineering that could be made possible with a metal that can fairly easily be made more pliable vs hard and what making a soft honeycomb with a rigid exterior or maybe using the same idea to print a single piece lock.....

Also easy local customization of synthetic bones or plates (anyone want money - bet there's some here).

I just saw something like this at USASEF this weekend. They were printing collagen (for example, to make heart valve) into a viscous gel. The gel could easily be melted away by raising the temperature a few degrees.

Lots of metal sintering patents rn out a few yers back so with  servo controlled laser and a squeegee your good to go.

I checked this out a few years back to make precision metal pieces, but powered silver costs were prohibitive. Figuring out how to DIY metl powder is the gme changer.

Talked to Matthew Velderman of Stanley Black and Decker about his $100K mass production metal printers t the time and he said  the quality of the parts still wasn't there yet.
