> then yes, that's vibe-carving.

This whole thread is a stretch, IMO. But, I like this phrase.

As a fabricator (large wood CNC, laser cutting and engraving, 3D Printing, UV Printing, Welding). I put engineering into a whole different job scope. I can make whatever you tell me really well, not vibe-carving.

I don't necessarily write the specs or "engineer" anything. I'm just saying, don't blame the medium, 3D printing. The fact is a fabricator is not necessarily an engineer, regardless of the medium.

Don't get me wrong, wood is great, I've made a lot of things and replacement parts from appropriate woods.

Using scrublands wood (slow growing tough long grain mulga) as a skid when a rubber tyre destroys itself is an old old hack passed on by my father (he's still kicking about despite being born in the early 1930s).

In the early 1980s I used to enjoy hanging out with Chris Brady and helped out making jigs to assemble snare drums: https://www.youtube.com/watch?v=jdBHtUN5gAE

His jarrah, wandoo, and sheoak snares are still loved: https://www.youtube.com/watch?v=tKmDuu5Iba4

Point being, I don't blame processes (3D printing, etc) for part failure, that comes down to whether the shape and material are fit for purpose, whether material grain structure can be aligned for sufficient strength if required, whether expansion coefficients match to avoid stress under thermal changes, etc.

Engineering manufacturing can sometimes be suprisingly holistic in the sense that every small things matter including the order in which steps are performed (hysteresis) .. there's more t things than meet the eye.
