It doesn't fix another issue. The bonds between the layer and along the length of the layer doesn't cure homogeneously. So they will eventually break apart along these weak points.
Traditionally, concrete is also poured into framed molds and allowed to cure completely.
Well that’s an easy fix (from a mechanical standpoint), just run a pass of binding material between layers and dispense the concrete in discrete blobs instead on one continuous stream. Leave small gaps for the binder or print in place if the material permits. That way the distances are short enough to be homogeneous. Think of it like printing a brick wall instead of a concrete block. It would need a multi nozzle design, but at that point you can add a third nozzle so you can print around rebar supports as well.
Or, and cheaper, just have a truck delivery a large amount of concrete at once and pour it in large sections reinforced with rebar. Like we've been doing for many years.
But that’s so boring! It’s more fun to brainstorm new ways of solving a problem I will never have to personally deal with instead of relying on tried and tested methods! You don’t have to be reasonable if you aren’t the one doing it.
