Recommendations for a 3D printer with build area of 400x400mm or greater?

I concur.  Corners can be protected against heat variation with the right set up.

Now that is a printer.

I did just now run across this 500x500x500mm corexy printer kit that looks as though it might be ready to buy today.

They also claim to have some kind of tool changing setup based on E3D's open source design:

Unfortunately, rather than photos it looks like a lot of CAD  renderings, so I'm not sure how real it actually is.

Wish these kits had the option of including electronics. Not thrilled to be spending that money and still having to find the right steppers/board/firmware.

I'm just the opposite: I'm more worried about the mechanics of their build than I am about electronics or firmware.  It says:  

Designed around the popular Duet 2 wifi and Duex 5X board running reprap firmware.

At least that much seems pretty typical for these kinds of printers.

RE: Recommendations for a 3D printer with build area of 400x400mm or greater?

Duet 3 would make more sense than a Duet 2 with an expander board, however.  Duet 3 is made for handling a greater number of steppers (like the 3 on the z axis) whereas I get the impression Duet 2 is aimed more at an i3 design.

That said, it does look far more rigid and professionally designed than, say, a hypercube evolution, which is sourced from 2020 and 3030 aluminum extrusions and generic angle brackets:

Well, anyway, I sent them an inquiry and I received an automated email which promised a response within 24 hours.

If I had to guess, based purely on what's presented, I'd guess it's run by an engineer with a day job who put up the website to test for market interest before deciding whether to commit resources to it.

It is Chineese New Year.  You might not get a 24 hour response.

@dimprov

On the Big-60, I contact the Maker Space and they confirmed wit takes two standard outlets - total 1650 watts.  One outlet for the heatbed and one for the rest of the printer.

I think these kits have promise.  

RE: Recommendations for a 3D printer with build area of 400x400mm or greater?

No response from 3dfused.  It looks as though the primary way to learn more about it is to join its facebook group.

It also built an i3 printer, and there's video of that at least:

From the looks of him, I doubt he's in China.

Anyhow, other than the Voron, it seems as though all the other corexy printers for which there are kits follow the same basic notional design, and there is a book on amazon which alleges to explain how to build it:

@cwbullet

Thanks for confirming that.  I guess I will have to look at upgrading the electrical in my house before I get one.

RE: Recommendations for a 3D printer with build area of 400x400mm or greater?

The Big 60 is especially interesting because its heated bed can be set to a smaller footprint for small print jobs or the full footprint for large print jobs.  I'm not aware of any other 3D printer with that kind of flexibility.  Regardless, adding an extra circuit is usually not a big deal in most stick built homes.

Last datapoint:  Kay3D is interesting because they make a corexy upgrade kit that converts an Ender 3 into a corexy machine.  Consequently, it's not large format, but it would be a bigger build volume than, say, the Voron zero.  Cost is around $500, including the price of an Ender 3.

Anyhow, the CR-10 Max I ordered arrived a day early.  Up until now I could have cancelled delivery if I had found a viable corexy at a comparable price that was ready to ship.  The theoretically higher speed and print quality that might be possible on a corexy would have been nice to have, but it would not compensate for the time lost on my current projects while waiting for, say, a ratrig to be released and then delivered.  Thank you anyway though to the person who suggested ratrig.  It was a good suggestion.  If ratrig had already been released, I probably would have purchased one.  That said, when/if Prusa ever does release a cutting-edge well-engineered large-format Prusa corexy, I may yet buy yet buy a Prusa XL, as it would likely usurp my use for the Prusa i3 MK3/S.

RE: Recommendations for a 3D printer with build area of 400x400mm or greater?

Actually, Ultimaker kinematics (what reprap calls "parallel kinematics") looks a whole lot easier to implement than corexy and it has shorter cables too.  I don't see any downside to it really.  Two years ago there was the FLSun Cube for $250, but it looks as though it may no longer be made anymore.  In contrast, the Ultimaker's all seem to be multi-thousand dollar.

Anyone here aware of any other sources for this style of kinematics other than Ultimaker?

That link says "out of stock."

RE: Recommendations for a 3D printer with build area of 400x400mm or greater?

It doesn't say that for me.  I looked on their website and it appear you are current.  

RE: Recommendations for a 3D printer with build area of 400x400mm or greater?

I guess that website must like you.  😀  Just to be sure we're on the same page, you don't see either of the following?  In the first screen scrape I highlighted the "out of stock" text to bring attention to it:

and in the second, I tried to buy the FLSun Cube on the same page that you linked, but the website gave me an explicit out of stock message:

Again, just to be clear, neither of those warnings show when you visit those pages?

RE: Recommendations for a 3D printer with build area of 400x400mm or greater?

@dimprov

I see it now.  It was not as clear as it should.  FLSUN appears to be dedicated to Delta printers now.
