Preliminary expectations and design options for a prosumer, fully opensource 3D printer. Your opinion matters!

Call for feedback: designing an opensource, prosumer-grade 3D printer

(update 2017: this project is no more alive, sorry!)

We are currently designing a 3D printer for advanced, serious, or professional usage.

The main target is reliability. The price tag is secondary, but we expect it to be $3 to 5K. Would you help us with this short survey? Being open source, the preferences of the community is very valuable to us, and we think it may be a win-win strategy.

Update: as an example of a forthcoming growing list of publication, here is an automatic bed leveling and head height adjustment.
