Oh, good grief. I suppose you're going to tell me that a concrete
pump is a 3-D printer, too.

Hook it to the right controller and it is. I saw a youtube of someone
printing a kid's playcastle using a concrete pump device of some kind.

Don't be an idiot. The thread is clearly about modern marvels, like
carbon fiber, not concrete. Geez, people turn intentionally stupid
when they run out of ideas (like leftists).


whoa! "print" a garden using dirt !

"Print" a wood framed House !

"Print" sand castles at the beach !!

"Print" new teeth in place, (dentists)

"Print" new shoes onto your feet !!!

(leftist will run with that, also CNN)


Today, I would like to print a copy of keys which cannot be made at
the keymakers anymore.

Jewellry, utilities, tools, gadgets.


Could you be any more vague?

"Vague"? Do you not know what jewelry and such are?


Why on Earth would anyone print jewelry? Plastic jewelry? ...or are
you going to print gold? BTW, I'd like to see you print hardened
steel and water companies, too.

I can see a few, very few, people printing junk jewelry, mostly teenage
girls.


3D printing actually is quite useful as part of a bespoke
jewellery-making process. You design a 3D model using a CAD program
such as Jewelsmith, print a positive, then use investment casting to
produce a one-time mold, which is used to mold precious metal.


I can't see anyone printing an electric, gas, or water company.

Tools and gadgets are so vague they are meaningless.


Tools? I just 3D-printed a fixture for stencil printing a PCB. It
holds a small panel (snaps into the mounting holes) and has cutouts to
allow the PCB to sit flat after parts have already been mounted on the
other side. Crude but more than good enough. A machinist would have
charged me perhaps $500 and taken days. And I would have gotten bogged
down in toolpaths and cutter compensation and such like programming it
myself in a CAM program.
