3D printing with titanium. (http://www.core77.com/blog/technology/imaterialise_get_your_rp_on_in_titanium_18330.asp)
Titanium is by far the hardest and strongest 3D printing material. It is also extremely accurate and biocompatible. We are very curious to see which of the host of possible applications that are open to designers will be used by them We think that titanium 3D printing is a powerful production technology that really adds to a designer's arsenal.

Every home will have one in the near future...all people will have to do is buy material....
Johnny needs a new bike....picks out the one he wants...pays a fee to the designer and downloads the plans....pop..a new bike from the "printer"
No need for shipping fee, no waiting, (unless they are out of material), etc.
LoL...? possible....who knows!!

Raises some interesting questions ...

How would you control the printing of weapons and guns ???

Will it be similar to our fabulous DVD encryption software or will it send and email to the ATF letting them know you just printed a gun ?

Hi,

I'm not sure if it will really be much different than it is now for firearms. They are incredibly easy to make with common everyday items even now.

I do suppose if you wanted to download and "print" that new Poli SxS 20ga. shotgun, it would be a fairly simple matter make you fill out what ever forms are needed and to wait for a background check before downloading. Digital signature required for proper verification of course.

Well not quite the same. Lots of people don't pay for music or software any more. Once it's digital anyone anywhere can get a copy legal or not.

"Titanium is by far the hardest and strongest 3D printing material. It is also extremely accurate and biocompatible."

They're being more than a little creative with marketing. As our own George Bulliss mentioned here two years ago, EOS been able to print sintered titanium alloys and high-speed steel for awhile now, so you can "print" specialty cutting tools.

I posted a video 2 years ago of EOS 3D Printing a turbine fan.

The turbine blade is at 5:56. Surface finish is pretty lousy -- all the shiny, pretty parts have a subtitle that says that the parts were electropolished :)

Edit: looks like that company Tucker posted is serving as a broker for EOS 3D Printing services :)


Pricing

A Standard part 2 by 2 by 4cm with a volume of 1 cubic centimeter would be 93 Euros ($124).

A part with the same bounding box and 4 cubic centimeters of volume is 144 Euro ($192).

I mentioned this very thing here about 4 years ago. The pioneering work was being done at MIT at the time.
The last I heard MIT was experimentung with 3D printing vitreous metals.
On one of the DIY sites there is a homemade 3D printer using epoxy as a medium.

And how do you know that classic Mustang for sale is legit, or one that someone just printed out?

If you watch the video I posted, Direct Metal Laser Sintering (the process described in Tucker's link) is much more complicated than that: it slowly builds up a 3D construct of soft, fragile powdered metal, which must then be fired in a heat treat oven to sinter it. The resulting object is porous, so it doesn't have universal application.

We're at least a decade away from being able to sinter a handgun.

Besides, guys are milling handgun parts on their hobby mills right now, so how would an additive process be more malevolent than a subtractive process?

I liken it to the very few real hackers out there, and the very large number of "script kiddies" that hack using tools created by others who are more skilled.

In this instance there are only a handful of hobbyists (thousands???) that have the motivation and skills and tools to make their own reliable and accurate rapid fire guns. The advent of a 3d printer will bring the capability within the realm of anyone who can program a VCR and assemble a gun from parts.

That's were it gets sticky. You don't need to replicate the gun, just the parts that are not widely available such as auto-fire sears.

Personally, I do not see 3D printing as a bad thing. A bit over hyped, but not bad.

Hi,

Actually, I believe a Scandinavian metal company has demonstrated a sintered powdered metal Damascus rifle receiver. The name escapes me, Damasteel? And of course there is Crucible's powdered metals like CPM-M4 and CPM-D2 that could also serve possibly. They are noted for being incredibly tough at high hardness due the extra fine grain structure of the steel.

While the technology of printing a machine gun at home isn't up to snuff today, it will be one day. And viable economics may make that day even farther off. Anyway, I'm not so sure I'd want to ride a bicycle with a sintered frame from a printer just yet either.

Oh stop worrying about guns, guns don't kill people, people kill people.

Who cares if everyone has a machine gun? The world would be a safer place.

These machines only use G Code, so what's wrong with editing the code and making one with a smaller mouth ? or better still no vocal cords ?

Powdered metallurgy and laser sistering are totally different animals. Powdered metal tool steel is cryogenically powdered to produce a tiny grain size, and then the powder is hot-forged into a homogeneous billet. Powdered tool steel is stronger and more wear resistant than conventional metallurgy tool steel of the same type: D2 versus CPM D2, M2 versus CPM M2, etc.

The laser sintering in 3D printers activates epoxy resin in special powders made specifically for that process. The printed objects are exceptionally fragile until they're fired in a heat treat oven. After heat treat, you have a strong, but porous, metal matrix.

Evan posted a web site of an artist who takes the sintered metal objects and then dips them in molten bronze. The bronze fills the pores in the metal, and you end up with a beautiful gold/silver damascus-like pattern.

Hence the vitreous metal.
Supposedly they will be able to custom design a metal for any application and then make the objevt with a 3D prototyping machine with no secondary operations.
They are already making replaement hips out of vitrous metal which are lighter and stronger than titanium.
