Robo 3D R1 or the non-cartesian Polar3D Printer?

[Magicolor]

I went over and looked at this wanhao company and they have some nice printers. Im looking for
a good one with a pretty large print area and this company seems to be doing things right.
Looks like they can print with lots of the filaments out there and can change their heads for
different filaments and the usnits look built well. Some of large print area machines Ive been finding
seem to be flimsy. Im looking for something proven and keeps working.
Im also looking at the BigBox on Kickstarter and I like the idea that they can use any filament
on the market. They can change their heads out and they have E3D as a partner with them.
I think they may be setting new standard when they hit the market in Dec of this year looks
like. They have a pretty large build area too.

As you mentioned large build area, E3D print head, filament compatibility, solid printer body,
I recommend you Fullscale XT Plus,
it is a large build size printer at 260*260*300 mm,
dual all metal 300 degrees extruders (similar to E3D V6),
full steel enclosed printer body.

If you are a green hand of 3D printing,
it might cost you some patience about plate calibration at the very begining,
but once you get the point, you are on a highway to funny printings!
