"LCD contact SLA" 3D printing: is it a legit technology? What are the downsides?

Well, I am always skeptical of a kickstarter, because if it were such awesome tech then theoretically they should be able to get funding, but there are good reasons to go that direction, I suppose. I think it's good mostly for hobbyist machines that aren't truly groundbreaking in scope like the Filastruder, LittleRP, or the SeeMeCNC Rostock Max v2 where there is a working final product and a small production batch initially that will ramp up into a small flow of products.

However, this looks like a decent machine with well-developed technology. The people behind it claim to have spent ~2 years engineering the "Alpha" prototypes that are in full working condition and are looking to fund the "Beta" prototype from tooled parts that will eventually make it to the final product. It uses a blue wavelength rather than UV as far as I can tell from the information I've gathered, but I don't really understand those implications.

They claim a resolution of ~75 microns on X/Y from a 2560x1600 pixel LCD and they claim it's liquid cooled to speed the process, but I have trouble, even with the video proof, believing that it operates at 1000cc/hour while they also claim that SLA such as the Form 2 do ~10-30cc/hour. I don't know if 1000cc/hour is realistic, but it seems to be (at a glance) unrealistic considering that wild speed claims in theh 3D printing world usually tend to be false. Again, I'm no expert.

The price isn't super low, it's in-line with where I feel SLA printers are going in the next year or two (~$2000 retail), but the kickstarter versions are quite cheap, so I'm worried they won't be able to recoup any engineering failures or delays due to poor parts QA, which is a common failure point for a kickstarter.

Overall, if I had $1200 to literally throw into the street, I might use it on this instead, but if it does make it to production I'd be poised to purchase one if it works well.

Thanks for the info!
