In the comparison photos, is the poor quality one from something like a MakerBot? Maybe I've never seen a close-up photo before, but I always thought they created higher quality than that.

it's an issue of the size. makerbots can print nice looking things but not that small. the objects being compared are the size of a quarter.

The call to action link says: "Pre-Order on Kickstarter" They must have not gotten the "Kickstarter is not a store" memo. They appear to be ready to pull the trigger on their manufacturing partners, so this is sort of a "how big should we make the first run?" type of kickstarter rather than a "let's create something awesome". Details… • Stereolithography printer (laser, not extruder) • Much nicer than extruder style…

The layers seem to be 25 micron vs 100 micron for the Replicator 2, although I'm not sure what they mean by the 300 micron resolution:

Yes it is. Extruded pieces can be pretty gnarly. This is exacerbated at small feature sizes, which is what you see here, especially on the birdcage which is about 3cm tall. To be fair, most people would clean that birdcage up a bit before showing it to anyone.

Most of the objects you see on the page have been cleaned up. For instance, over the "Accessories - Form Finish kit:" heading you see a part that hasn't had its temporary supports removed. The bracelet is a little furry on the bottom. It looks much better near the top of the page where it shows in a montage after cleaning.

Can an expert in 3D printing compare this with, say, the MakerBot Replicator 2? How does the extruder technology compare with SL on resolution, hardness, speed of printing, etc?

Lithography printing from what I've seen so far is significantly better than extruder tech. We have a Projet 1500 and an original Makerbot at my hackerspace (Columbus Idea Foundry). The Projet absolutely kills the makerbot for resolution and jitter. If you made a sphere on the projet, it will be pretty damn smooth. On the Makerbot (original) it will have a strong texture to it. No experience with Replicator 2.

Yet, its also around 10x as expensive to run (ABS is cheap, whereas the liquid stuff is expensive). It also takes a lot more room (there's separate machines for a drying/curing thing). The resolution on the Projet 1500 (which isnt the best one in the world, just what we have) is pretty limited at like 1024x768 since it uses a projector instead of a laser. I'm thinking the laser might allow for finer resolution, but I'm not sure.

Also, our Projet machine won't operate (like, at all) if its above 75F. Most of our hackerspace is un-airconditioned in a warehouse, so that just doesn't work. We had to get an AC and put it in an office. Extruder machines just don't care.

I haven't used the Replicator 2, but the replicator looks promising. At the same time, if the Formlabs ones does as it says, then its a HUGE move forward as its around 1/10th the price of something like our Projet 1500.

This looks pretty exciting initially. If I had the money- I'd consider buying one.

I put together a small comparison chart in this post: http://www.wired.com/design/2012/09/formlabs-creates-a-low-c...

That birdcage was actually pre-cleaned to make it look as good as possible.
