Does it look anything like this? (All angles are right angles, BTW):

Anyone who read science fiction back in the 1960s knows that the 4th dimension is time. Unless the produced objects enable time travel, they cannot be described as 4D.

Kind of like the jacket in “Back to the Future” that drys itself when wet.

no matter how hard I try, I can’t really imagine what a 4D object would look like.

If only Escher had had this technology to play with.

Maybe the printer has a timer on it.

Nano particle additions to cotton fiber have been used to create jeans that shed water and remain dry.

They do travel in time. Forward. Like the rest of us. ;-)

“Anyone who read science fiction back in the 1960s knows that the 4th dimension is time. Unless the produced objects enable time travel, they cannot be described as 4D.”
Only SF writers who don’t know anything about science. They should have read Flatland instead of A Wrinkle in Time.
We live in 3 spatial dimensions and 1 temporal dimension. A 4th spatial dimension would add another set of points (W,X,Y,Z) like the tesseract displayed earlier in the thread.

I see 3-D printing as just one small area in the ever expanding world of technology. A lathe was needed to make the printer nozzle. Microcode and computers on a chip to control it. Hobbyist and robotics fan-boy websites, as well as thousands of youtube videos reveal amazing things people do in their garages and dens. 3-D printing is sort of an adjustable wrench in the larger scheme, as amazing as the milling machine or silicon lithography when they first came out.

I've got a lathe and milling machine. I can make 1600s era firearms just fine with them, thankyouverymuch. But 3-d printing really opens up fabrication possibilities that my standard subtractive technology can't do, like complex internal structures.
Printer nozzles can be printed. Just like I can build another lathe with my existing lathe. But you have to have the first one.

i thought 4 d was the power for one solid object to pass thru another.

Pshaw. I’m waiting for the 5-D printer to come out.

Dumb science journalism. It’s a shape-changing (bendable) 3d object.
