I think both Rocket Lab and Relativity Space realize that even with 3d printing they can't compete on price without reusability. If SpaceX is even close to hitting their costs per launch with Starship/Superheavy they can undercut everyone, even to launch small satellites. SpaceX is shooting for $2 million per launch with Starship, that's cheaper than Electron today and Relativity Space's Terran 1 is planned to cost. Heck for small sats SpaceX could probably put them into orbit with just Starship and a kicker stage and not even have to fire up Superheavy.
