This is one of Nicholas Seward's designs, though it's in such an early stage, he hasn't really designed much beyond putting up the one concept animation you've found. Oddly, he hasn't started up discussion on it here on the boards, just on Google+. (and where it got some exposure on the 3D Print Board forum.) It seems like a pretty logical combination of the Mondrian and CoreXY platforms, thouby Feign - General

Oh wow! I don't envy you the task of lifting and placing those turrets. (though they look amazing, I gotta say.)

It's worth noting that the Blacksmith team seems to have done just that, though they've gone and made a Indiegogo campaign for their printer ( I wish them the best of luck). It doesn't look much like a RepRap anymore, with a built-in laser and camera, for both 3D scanning and remotely monitoring in-progress prints. IMO, the $1,400 price is a bit much for the average RepRapper, so there's not aby Feign - Polar Machines, SCARA, Robot Arms
I'm a bit curious about this, especially the vinegar test. While vinegar has a little bit of ethyl acetate, it's mostly ascetic acid... But from what I understand, it's the acetone in it that does the magic, so there's reason for it to be feasible. If PLA can be smoothed with old-fashioned vinegar then I think we'd have a winner.by Feign - General

Definitely looking forward to getting one of these, though it's a shame it's PLA only (though I understand why).

CoreXY has two belts, each of which is on a planar belt path. No matter how stiff the frame, the HBot's torque on the y-axis will add friction to the y-axis bearings even if the frame is stiff enough to not allow defoby Feign - Mechanics

QuotecozmicrayA Wally cousin?This has more in common with the Morgan than the Wally. (Though the Wally was itself a decendant of the Morgan, so I guess cousin could be accurate) The Morgans have been very practical, heck there's some small mechanical changes that could be made to the Wally to make it a more practical branch.

Oh wow, that's just looking awesome! Of course, this project allways has me asking "How do you put a roof on it?" The tilt-up method the Chinese printer uses can do it, but that's (currently) very restrictive, footprint-wise.

See from my view, open source makes sense in many cases because the cost-benefit balance of protecting IP is not terribly favorable these days and getting more and more grim as time goes by. When a company releases a product, their competitors have it reverse engineered within a week. Aggressively defending patents seems like a way to squeeze out competition on the surface, but in the long runby Feign - General
Alternately, you could have two of the arms attach to the center pivot on large lazy-suzan style rings around the perimeter of the middle 'platform' where your hotends (or direct mount extruder) and stuff are mounted.

I'm gonna echo DrDIV, self-replecation is a goal in the same vein as getting to the moon was a goal. The value isn't in the destination so much as the advances made on the journey.

I wonder about using a paste extruder to make objects out of Bakelite or other similar thermosetting plastics, which allow quite a bit of working time before they cure. In any case, there's certainly nothing stopping you from getting such an extruder and printing with porcelain clay.

QuoteSrekProducing non round material would be costlier and i can't see much of an advantage.I could see ribbon or tape being more suitable for running reliably through rollers, less slippage in the extruder, less risk of breakage in shipping.

At a large scale, you can forget machines that have a moving bed, restricting you to x-y-z gantries and Delta style printers. Most of the large format printers have been cartesian gantries, I'm not exactly sure what limitations the Delta format faces when scaled up...

While this is an awesome concept, I see some problems... Namely the Gripper bot doesn't have a way to handle intersections.

I sort of understand the problems with the basic turntable style polar printer having the hard to resolve center point, but like I said before, I'm not a math person so much as a general concepts guy.

Actually, I kind of thought this might be useable with the polar printer idea waaaaay back in UnlimitedBacon's thread (link to that old post.). With the weight on the lower arm of the z-axis, you would have the printer default to an open position, and not risk the hotend falling onto the print if you lose power.
