3D printing does bear some similarity to vibe coding/LLM-generated code. I do occasionally see "product" 3D printed items but the bigger value-add for 3D printing has been rapid prototyping and then running that design through actual production testing.

An example 3D workflow: Prototype design -> 3D print -> test/break -> production design -> real manufacturing process

The equivalent vibe code Vibecobe -> slop -> test/break -> real developers -> real development process

The real test for vibe coded stuff (much like 3D printed crap at craft fairs) will be if someone actually buys it. But much like those 'makers', vibe coders will have to go through the "real development process" if they want to make money at scale.
