Some impressive tooling will be heading to the factory: http://www.rrstar.com/news/20180717/rockford-made-machine-to-build-parts-for-next-generation-rockets (link discovered by reddit)

Ingersoll Machine Tools has built the largest machine of its kind in the world for the world’s richest man — Amazon boss Jeff Bezos, who will use the engineering marvel to build rockets to carry humans to the moon and maybe even Mars.

It took three years to design and manufacture the Sasquatch-sized machine, which stands 51 feet tall, 136 feet long and 43 feet wide. The machine — its trademarked name is Mongoose — will be disassembled in coming weeks and shipped to Bezos’ Blue Origin rocket factory, at Kennedy Space Center’s Exploration Park on Merritt Island, Florida.

There, the machine will be reassembled and will manufacture cryogenic tanks that will be filled with liquid oxygen and hydrogen to fuel rockets. The machine also will build fairings — large aerodynamic structures that encapsulate rocket payloads like satellites and other critical equipment.

it's a fiber placement machine, and they said it will be used to build tanks, does this mean New Glenn will use carbon fiber tank too?
It seems possible.  The machine will also build fairings, the story says, and is derived from similar machines made by Ingersoll used to build 787 sections.  Here's a video of a similar Mongoose machine in action.

I find this amusing.

If the NG is indeed a fiber composite cryo tank it will proceeded as an operational LV to that of BFR. Both of which will be large diameter applications. If this is correct this portends the beginning of the end for metal tanks on LVs. With Electron using all composite tanks/structure, BFR, even OmegA using composite case large diameter SRBs, and now it looks like NG as well completes the picture of advanced new designs of LVs (except Vulcan) going in the direction of carbon composite to save vehicle dry weight and improve performance significantly.

For reusable vehicles tank dry weight and it's ability to be reused often with very high strength margins for its weight is the holy grail. So far there is two candidates for this supper light weight tank structure designs: stainless steel balloon tank and carbon composite rigid structure. ULA is using the stainless steel balloon tank design for the Centaur V and follow-on ACES designs for weight and they have significant experience in manufacture and handling it. For others the choice of going with carbon composite yields about the same price point for performance as the stainless steel balloon tank design. It is interesting to note that carbon composite manufacture is mature enough that it yields a superior tank for the same ~costs as a aluminum alloy tank and may even be easier to manufacture for large diameter.

So awaiting the confirmation of whether NG is going to use carbon composite cryo tankage.

Interesting that it says "and hydrogen", with no mention of LNG. If that's accurate, it would be the upper stage at least.

In 2016 Bezos said the factory would have a "large-scale friction stir welding" machine. I can't imagine much use for such a machine on a rocket with carbon fiber tanks.

Sounds like upper stage / fairing to me.

Main reason is that it seems a bit short for the first stage.

Perhaps this should go under "advanced concepts", but a carbon fiber balloon tank could have an amazing mass fraction.  Carbon fiber is lighter and stronger than stainless steel, and if you can keep it purely in tension, as in a balloon tank, you can use these properties to the full.

As of 2016 New Glenn was said to use friction stir welding. Since this only mentions hydrogen and oxygen, most likely the first stage is still metallic. Also, its a bit of a reach given the image quality, but I found this cutaway picture which seems to show metallic first stage tanks and a composite second stage

Definitely not the best pics
