Unfortunately this incredibly selfish and screwed up claim may have a scientific basis: http://www.ted.com/talks/william_li

I only hope she didn't pull focus and attention from these actual doctors who are trying hard to find different solutions to a shockingly misunderstood illness.

I'm not extremely familiar with the SLA process, other than the fact that photo resin is hit with a UV laser, but have been thinking about the possibility of a rotary style printer. Does anyone know if it has been done before? I'm thinking a slotted wheel with the head/laser much like a CD player...

Oxygen inhibition is all the rage from the Carbon3D videos, but it's not necessary to get too carried away with that tech. There are plenty of ways to SLA print without it.

Itching for a test flight.

I know that this has been done before, but was wondering if anyone in the community has tried and succeeded. I'm using a Da Vinci 1.0 ( so, so far this has been complicated).

I've tried cold acetone vapor smoothing, but don't have the equipment to try the more dangerous hot technique. It did smooth the part quite a bit and gave me a nice sheen, but also turned out slightly hilly where there were thinner areas of material. I'm thinking if I can't remove the small ridges they would simply result in a more gradual bumpy surface. Also, the last time I attempted the cold method it didn't work for some reason...not sure why.

Does anyone know if there had been any initiative to build smart slicers tuned for things like thermal stresses, shortest paths, and least amount of support material? I'd love to try to create/help with some slicer software.

 I think it is very possible to do what you are saying, and it would be very fast to change the layer thickness using surface projection on the analytical geometry. I'll get crackin' on it. This can go on my projects list right behind everything else...so like 2 years from now ;-)

Sony is so behind the game. That price is insane. Check out the Cowon players if you want great audio and long battery life. The X9 has 110 hr music listening life.

Found a great new band: The Interbeing. A Danish mixture of Mnemic and Sybreed.
