lintel

Brick houses used to have stone lintels over doors and windows.

Sorry to nit-pick, but I think you meant lintel, not lentil.

This was a machine to make stone lintels for the tops of doors and windows in brick construction.

Being one of the first lintel democracies implemented, it got some things wrong.

But lintel consumption didn't go up, because lintels are a small fraction of building cost.

For starters I assume they wear a helmet with a face shield so they don't eat the lintel every time they step into the carriage.

But the size of the stone lintel market was determined by the rate of house construction, and cheaper lintels didn't affect that much.

That's not concrete obviously, but it too is under compression almost entirely, except for the corbel and lintel ceilings.

Still, it does seem pretty plausible that you could roll a big stone lintel up a hill of sand, or carefully balance it onto progressively higher stone pivots, without knowing the Pythagorean theorem.

If this guy had an actual 3D printer he would realize those doors and windows are a no-goIs easily solvable though by having the robot drop a plank across the gap before printing the lintel, so I don't think that is a showstopper.

His first email to employees, sent just after he assumed the CEO mantel on earlier this year, was filled with bombastic and false platitudes:”mantel: a beam, stone, or arch serving as a lintel to support the masonry above a fireplacemantle: a figurative cloak symbolizing preeminence or authority <accepted the mantle of leadership>
