Not to be a stickler, but a dove tail is a sliding joint- the dovetail itself is a trapezoidal section with the narrow side facing the part it’s on.

The slot is similarly cut so it slides into place.

This is (basically) a fat biscuit join, which is good. Peg designs might be better - prefer pyramidal pegs, they self center and have more surface area for glue, and they print neater when they have suboptimal orientation to the print bed.

And this is, in fact, a dovetail. It slides into place. He just happened to do it on a curve. He shows it in motion at 4:00.

Skeptical of this, while the dovetail is a good joint in woodworking, it's not really the best joint for most applications. Even drawer boxes.
Modern glues are so good, that just a normal box joint or even a rabbit joint is actually stronger when properly made.

While you can control the layer lines and orientation to some degree, I'm thinking that a dovetail, in real designs, would be extremely hard to implement. Peg and hole with CA glue is most likely better when splitting parts that are too big for a bed.

For anyone confused I looked it up, a rabbet joint is what they call a rebate joint in the USA. Learn something new every day! :-D
