3D printed titanium parts
MEAT:
Well given the fairly limitless design possibilites adative manufacture allows, charges effort does look a bit unimaginative and casting like, especially in comparison to some of the other whacky shit up there?
I've heard gartners hype cycle mentioned regularly with regards to rapid prototyping, its a graphical representation of the publics reception of new technology over time, starting off from zero, with expectations growing hysterically, in our case sweating over entirely printed bikes, thoughts of downloading the latest cult stem off bit torrent and printing it in your bedroom, etc. Look theres 3d printing on the crest of the wave....
Then it all comes crashing down when you finally get your hands on one of the consumer products shown above and you realise how primitive the are in comparison to your £40 inkjet printer next to it. Oh and your printed frame you outsourced will cost more than your house and likely wont have the tolerances or strength of a bog standard tubular one. So that takes us to the very bottom, but eventually technology catches up and some of the original ideas can be realised and it levels off to a sensible state... were still a very long way from all this yet though, wouldnt go getting too excited avpbout it for now.

Looks like it has fairly clear tool paths on it?

here's another pretty big object that I've just seen for the first time...

the article is still good. maybe it's a tinypic/photobucket problem... but that's fucked
MEAT:
Ah... guilty. I'm sure they arent structurally, but the parts do look rough as arseholes before they're machined? I figured it was more like laser sintering from a powder, rather than just a robotic welding arm....

I don't really know much about this whole 3d printing thing, but I saw this
