The University of Maine's Advanced Structures and Composites Center 3D-printed a tiny home.
It encapsulated wood waste from local sawmills in a bio-resin to create a durable printing material.
Take a look around the 600-square-foot home's bathroom, living room, bedroom, and kitchen.

Most or all of this drama, humiliation, wasted taxpayer money could be spared -
with even modest attempt at presenting balanced facts from the start.
#1. That must have been one gigantic printer. Or else the components were printed individually, and then assembled conventionally.
#2. There are already homes made from recycled wood waste, called “trailers”. The wood subfloor? Cheap MDF. The doors? Cheap particle board. These materials are literally made out of wood scraps or sawdust.
The quality is not great either. MDF around a toilet means replacing the subfloor in 20-30 years. Particle board disintegrates in a 30 year timeframe. Nobody bothers “recycling” trailers; just burn the thing down.

3D “printed” homes usually means homes that have been constructed using computerized concrete machines. That looks like a prefab home where maybe the walls were manufactured in one piece and then assembled on site. Probably some sort of computerized assembly that they are calling 3D printing.
This is what I think of when I hear 3D printed homes.

The way trailers are mass produced is impressive (and incorporates building techniques like that). The paint is all sprayed on nearly instantly and the roof drywall is likewise sprayed in a unique way. They can churn them out really quickly.
Since professional architects and engineers are responsible for the design they can also deviate from building codes a bit… you end up with a building that is technically structurally sound, but can be quite difficult to repair years down the road.

^^i have these same questions .. the University of Maine design wouldn’t have been so surprising coming out of Arizona or Texas.
My son has worked with 3-D printers, some large, in aeronautics, not home construction. The potentials are intriguing. Durability and flexibility, esp for homes, are important. Technology is built on obsolescence for profit, something lib activists never mention.

And it's not just pre-fabs that use MDF. Some builders seem to think that it is the greatest thing since *whatever*. It's a scourge when used on a roof. The slightest roof leak will quickly result in distortion from swelling or complete failure. Same for sub-floors, as you mentioned. Get a water leak under the kitchen or bathroom sink (or the toilet, as you said), and it results in a whole lot of work to fix.
Plastics in automobiles is the same sort of deal, although there it's mostly sun light that causes the deterioration. (Although there are molds or bacterias in the tropics that cause plastics to either turn into a glue-like goop, or crystallize. Same with many types of rubber, actually.)

The other problem with a lot of this prefab 3d printed stuff is that it is difficult or impossible to do good repairs. Want to knock out a wall, replace a window or door, deal with water or storm damage? Not so easy compared to traditional stick construction that is more or less infinitely repairable.
For that reason I don't think a lot of it is going to age well. How do you remodel a 3D printed house in 20 years?

Notice the lie sold that these houses are “recyclable”, when actually they have planned obsolescence. Conventional stick framed houses have always been “recyclable”.
I have a 40x30 shop/barn that the prior owner built by taking apart a derelict house and reusing anything he could.
