At least 80% of my FDM work is done below this wall thickness. Please don’t do this. One of my best clients places large orders almost every week for custom containers with walls that are often <.5mm. Are you going to start telling them that I can’t do it anymore?
I printed twelve 680 nylon medical prototypes a couple months ago with less than 1mm walls. I printed PEEK with .3mm for a major university last year. I printed graphene PLA for another University with .5mm walls. Would clients like this no longer find me after uploading their file?
Please rethink this. You guys are really scaring me here.

It seem they want the FDM printers gone.

Why would someone down vote this? Especially without explaining themselves? This is really sad.

Probably not hard to figure out who.

I upvoted it back to 0.
It takes forever to print a 1mm wall with a .15 nozzle 
Although keep in mind 3D Hubs doesn’t support FDM nozzle sizes at all and just lumps everything into the cheap and bulk slicer and model checker they installed.

Absolutely,
Parts at that resolutions are usually pretty small though. I’ve been experimenting a lot with multi-resolution prints over the last year. The trick is dual extruders with different sized nozzles. Then you only need to use your high res nozzle on perimeters or fine details.
Like you said, they haven’t even gotten around to incorporating nozzle size, so I doubt they have an interest in such things.

Their printability feedback/guides are based on what they (3D Hubs) sets as the limits for the printers. It is not an actual reflection of what the printer can do, but is there so they don’t have to give out refunds when a print with 0.1mm wall thickness fails.
If you’re comfortable printing it, than it’s not an issue. If I have someone upload something with really small surface details, and they are warned it may not print correctly because it’s outside of the design guidelines but choose to print anyway, then they have no financial recourse if the print doesn’t capture everything. Prints do still come though (I’ve had SLA files with details way lower than the limit come to me with no issue), so I think it’s more of a warning for the customer. Experienced customers don’t need this, but it is beneficial to customers new to 3D printing with broken files, impossible details, etc. That’s just my 2cents on it at least.

If I was a first time customer and saw that warning, I would assume I needed a different technology/hub. It’s not beneficial to the hub(unless you have an SLS machine) or the customer. If there is a problem with a file, I can promise you that I (and you) can do an infinity better job than 3d hubs and their automation.

That’s true and I didn’t think of that way; it’s definitely only there so they can cover refund issues.
