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.
