3D Printing

[SkeptiskParticipant 3679]

Some time ago I watched this incredibly interesting video at TED explaining a new trend in 3D printing. Possibly making “traditional” 3D prinitng obsolete before it’s even commercialized. Behold 3D printing in a new way…

Way cool!

Holy s~~~….

This is a game changer for 3D printing.

It is by caffeine alone I set my mind in motion, it is by the beans of Java that thoughts acquire speed, the hands acquire shaking, the shaking becomes a warning; it is by caffeine alone I set my mind in motion.

Awesome!

There’s something going on here.

Progress without testicle is the battle cry of the future.

Just how the hell did productivity and imagination come the the forefront without a vagina leading the way?

It’s gotta be a fluke.

Video isn’t loading here (f~~~ my internets). Is this the DLP projector under the pool of photopolymerizing goo method? Because that’s been around for a while. You can get insane resolutions out of it.

I’ll put of the URL at the TED-site.

Sorry, Sidecar, hope this helps. 🙂

Thanks.

Also, yup, it’s the goo. This sort of system has been around for a while, though the oxygen permeable build table is new. These things have a fast build speed and phenomenal vertical resolution, but the horizontal resolution is extremely limited by the projector being used underneath to illuminate the goo. Even a hypothetical 4K resolution projector (which I don’t think exist commercially yet) would be fairly limited. You can either have tiny builds at high horizontal resolution or medium sized builds at low horizontal resolution. And I suspect you can’t correct for that using a scanning laser illuminator like some other systems because the oxygen requires a single layer to be built and lifted out of the dead zone all at once. A laser can only polymerize a single point, and, depending on the chemistry, I suspect the oxygen would be de-polymerizing everywhere the laser isn’t any more.

Finally, photopolymers have their limitations. This system will absolutely crush certain markets (those guys who make those little dungeons and dragons figurines are pretty f~~~ed by it), but I personally wouldn’t trust an engine with any parts using this method or any other additive 3d printing method. I’m still waiting for a consumer market desktop metal SLS system, and even then I don’t think I’d trust it to make, say, a crankshaft or connecting rod.

3D printing is the big leap of technology.

Imagine if they sent robots with 3D printer on mars, they can make dwellings very fast and according to the blueprints without mistake and cheaper.

One day, your house will be built by 3D printer, i guarantee it.
