The problem is that additive manufacturing technology does not deliver the same economies of scale that traditional manufacturing does. The cost to deliver a 3d-printed part will largely stay the same, regardless of whether one or 100 are to be produced. This is in contrast to traditional methods, where it is far more cost effective to produce parts in large quantities.

The problem is that home costs (or the cost of any good for that matter) have little to do with material costs. Cost to produce a specific good really only sets the floor on prices. Demand will alway set the ceiling.

If demand pricing falls below the floor set by costs for too long, businesses fold or stop producing whatever that item is until supply constraints pull demand pricing up past the floor again.

3D printing of homes mostly looks to replace labor intensive on site work like pouring foundations / framing / drywall. Since that is traditionally done on site and fairly customized to the building site additive manufacturing is a good use case to reduce the costs considerably. But they won’t be passed to consumers since it doesn’t really increase home supply at any great leap.

There is still significant work to be done, though, on the quality of the final product.
