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've been putting off going to Columbus Idea Foundry, but with all the cool tech there I might just have to get my membership.

I'd highly encourage you to come by for a tour, and sign up for a class before jumping into membership. Not that membership just right away is bad, but doing this will give you a better idea of if the place is a good fit for you and your needs. Send me a PM if you'd like a tour or hit up our contact info on the main website.
