The finished parts are stronger than cast metals but not as strong as forged metals. DMLS machines are expensive but not out of sight of smaller companies; I saw one at a trade show recently advertised for $680,000.<br />Jonathan Jaechhttps://www.blogger.com/profile/10379443520888976176noreply@blogger.comtag:blogger.com,1999:blog-3758330678390419129.post-75888273173490911202013-02-17T10:44:18.957-05:002013-02-17T10:44:18.957-05:00I have five so far.

I don't doubt that you can print something that maybe semi-looks like a hamburger, but it's definitely not going to fool anyone with a real tongue and tastebuds into believing that it's a real hamburger. I'm talking about realistic texture and flavor (especially texture).

But if you want a complicated object with different materials composing different parts, that's a long time coming.
