Yes they can
Penn state did it with simulated Marscrete. check out this video that talks about it.

Mooncrete has been around for a very long time and also can work in printers. Some designs do consider polymers or water(ice can most likely be found on both the moon and mars) but others do not. I am not sure what this moon base program is considering

pic related is mooncrete made decades ago and they already have practice printing concrete. This video is the company meant for the moonbase printing at camp pendleton.

So basically as shown this technology is already here, has shown proof of concept and is available to NASA. It just has to be put together and polished into a single project. That project is the ICON- BIG-Bjarke Ingels Group-SEArch+ collaboration with NASA. Since the first landing on the moon is not for another 4 to 5 years at least that means that this project has the better part of a decade to flesh out their plan. That makes this project not only doable but Probable.

We have made cement from real lunar dust that was strong and credible. The excavators we use on earth require traction in the other direction of the dig that can be an issue on the moon/mars. A printer is much more hands off than an excavator/welding type of build and thus is less dangerous for the supervising astronaut. A lot of the work and maintenance can be done while inside instead of out on EVA. A 3D printer is multi use, It can be tasked to make tiles for roads, dust shielding for equipment and can change designs without needing retooling. You can reinforce the regolith you bury the hab in like pic related. It makes inflatable habs actually useful. All of you materials can be gathered from the dirt around you and you can add your plastic waste to make it stronger. AI makes the manpower necessary much lower and can make remote construction possible. It is meltable material so it is easier to deconstruct, it doesn't need to be as thick, it can be built above ground and you could have a bunch of rovers/gatherers for the weight of one excavator.
