3d printers are wonderful for rapid development, but are much slower than industrial serial production.

Quantity has a quality all of it own, and all that.

Ukraine is doing wonders managing tons of different producers and models, but Russia production capabilities have always been a problem.

Ukraine was in the lead with their interceptor drone. Unfortunately now russia has refined their drones to not be multiple pieces sticked together, and has added small jet engines.

The new drones are both too fast for interceptor drones and might even survive a hit thanks to the body made from a single sheet of metal.

Now the new russia drones cost about double, but intercepted rate went down from 90+% to about 55%. Math says the new drones are more than paying for themselves.
