There seems to be a couple variations on 3D / cad-cam dentures. So we're not entirely sure what has been proposed to you.

The impression taking involved can either be traditional (impression paste) or optical/digital (scanner).
In the case of a traditional impression, it is scanned (converted into digital) at the dental laboratory. So either way, the copy of your mouth that the laboratory has is a digital one.

Using that copy of your mouth the denture is then designed via computer. (So no, they don't print a copy of your gums, they print appliances that go into your mouth.)

The denture you go home with isn't a printed one. (During the denture construction process, some of the test appliances used in your mouth are printed items.)

Once the final form for the denture has been determined, then the actual denture is made. The (pink) base portion might either be:

1) Milled (cad/cam) out of a block of plastic. Then holes for the teeth are made and they are bonded into place.
2) Created using a process similar to conventional denture construction (kind of like injection molding), with the teeth then added later (a step that is not like the way conventional dentures are made).

As far as materials and "quality." Every thing we saw in videos and such was either associated with a dental school, a lab whose reputation we are familiar with or a well-known denture plastics manufacturer.

We anticipate that the materials involved (teeth, pink plastic) are very similar to those used to make conventional dentures (you should ask).

The biggest difference we noticed is how the teeth are embedded in the denture's plastic.

1) With 3D systems they are bonded in place as a later step, after the plastic is already hard.
2) With conventional denture construction, soft denture plastic is allowed to work it's way around the the teeth under pressure, thus helping to create a mechanical lock, not just a bonded one.

As your dentist about this point: Is there a history of teeth debonding from the denture base more so than with conventional dentures. We don't know that that's a problem but it would be our biggest concern/question.
