Water Music: Titanium parts are printed directly using the powder method.  Powdered titanium is 'squeegeed' across a platform in a thin layer and a laser scans the bottom-most layer, melting and fusing the titanium.  The platform lowers a tiny amount and the process starts over, each layer building on top of the last.  Eventually, when finished, the part is dug out of the powder and finished with baking and sandblasting.  Although other materials can be used in this process as well, Titanium is used due to its low heat conductivity; while this makes it harder to melt it means the 'pixels' of molten material can be small, hence fine detail is possible.

cooldude234: This argument has been used many times in the past whenever a new 'consumer level' process becomes available that challenges the commercial or industrial systems.  For example, when user-burnable CDs and later DVDs became available the music and movie industries were not happy due to the possibility of high-quality pirating.  This has in fact come to pass, these industries are indeed suffering as predicted.

<rant> 3D printing will be no different, it will be just as illegal to replicate somebody else's registered product as it always has been.  It's just that the relative ease with which it can be done will make it much more difficult to police.  The recent furore over the printable gun designs on the web was just dumb, it has ALWAYS been illegal to make your own gun (at least here in Australia) no matter how it was done, and frankly it ain't that hard to machine up a simple, single shot .22 weapon with access to a fairly basic lathe and a bit of engineering knowledge.  The fact that the 3D printable version is readily available on the web for printing at home doesn't reduce the illegality... print one at your own peril!!

Intellectual product will ALWAYS be protected by law, just because you can replicate a Lego block doesn't make it legal.  However, there is a big difference between 3D printing that one missing piece needed to complete your awesome model, and mass producing them for sale and profit.  The former, although technically illegal just like recording a song off the radio or ripping a CD, will be largely ignored as it hurts nobody.  The latter will, quite rightly, get you in a load of trouble. </rant>

I would like to add that if you were printing something in titanium that was closed (like a hollow sphere) then things like sand blasting wouldn't work. However sand blasting is mostly just for visual sake. At this point of time, certain metals can't be made certain ways (like making a hollow sphere), but hopefully in the future this will be overcome.

Just to say for the sake of saying: You can build your own gun here in Canada, you just need to fill out a heck load of legal papers (and other legal stuff) then on top of that you need to fill out a heck load more of legal papers to be able to use/own it(and other legal stuff) ;)

I was hoping you where going to say more about the food thing ensoniq5 but you didn't :P

Interesting, thank you.  As much as I would like to hit "print" on a Milanese chased helmet, somehow I don't think I ever want to find out how much one of these would cost.  Still, the thought should be enough to make my machinist friends jealous.

And yeah, if you want to make a gun all you need is a block of wood with a hole through it, a bullet, hammer, nail, and a very stupid friend willing to wait until you are a few miles away getting an alibi.  Not to be recommended, but not that hard.

it would be cooler to have one with piezo heads, some sort of plastic/solvent mixture, and semiconductor inks. REALLY rapid circuit prototyping without having to order stuff online.
