and then the universe blows up and the big bang happens again then the multiverse explodes( if that exists) and everyting beyond that is obliterted.

It is not possible for the universe to explode.

Theoretically, we are living in the aftermath of a huge explosion.

3D printers already exist, but they can only print in plastic.

Correct. There are also printers that can print circuits using conductive ink.

Yea, the itty bitty bang.

3D has length, breadth and width.

2D has length and width.

1D has length.

0D is a dot with a position but no size.

I don't think a black hole is any of those

Nothing is any of these. We just see things in one of these.

I think this kind of printing would be great for prototyping something without paying for mass production.

It wouldn't work that with the buying.  You'd need all the materials, and then you'd have to put it together.  But 3D printers do exist.  Also, black holes are either holes or 3D.

But you would be able to make a very professional prototype, straight from a design on the computer.

Blacks holes could be 4D if they exist in the theoretical 4th dimension, but this is getting off topic.

But the universe did not explode. My fact is still correct.

The Big Bang theory is not proven. It is not one that I completely believe.

It is one thing to be a theory, and another to not have any sufficient evidence.

Exactly. Although one reason why they invented the theory, is that the Universe is expanding continuously, however, this could be a continual expanding and contracting over time.

But even when you get past the boundary where nothing is, an area of nothing . . . is still an area.

And really, is the area past the farthest star systems any different than the empty space between two objects in space? The dark, empty void? I personally don't understand why people think that the universe is limited. Truly, with the current technology many of our predictions of the universe are likely to be wrong. With telescopes (and I don't just mean ones on Earth, things like the Hubble too) we can tell that the universe is expanding, but it is extremely difficult to be researching much outside of our galaxy.

Okay, I need to clear up so many misconceptions here.  I'll do recent first.  It's not really possible (or at the very least, practical) to compress something to the point of a black hole.  The only real way to do it is a supermassive star's (I meant supermassive as in just ultra-really-super-big) gravity.  The area outside of our galaxy is empty space just like within it (maybe with a bit less rock and dust).  But outside of the universe, nothing exists.  The very concept of 'existence' is not possible.  Although it may be difficult to think of, not ever space nor time exist outside.  It is so pure of form of nothing, that we, as forms of something, can not begin to comprehend it.  Of course, even fish can see the ripples in their pond, and given time, deduce the existence of rain.  Also, the universe is expanding at a speed far faster than light AND ACCELERATING (for reasons similar to above), so there is no hope whatsoever of any interaction with it.  Ever.  Next off, the big bang was no explosion.  It was NOT an explosion inside space and time.  It was an explosion OF space and time.  It was a massive expansion of the concept of conception itself.  It is impossible to truly visualize it and see a big exploding ball getting bigger really fast, because outside of it, there is neither space nor time.  Just thinking about the speed it was going at- then, which has gotten faster today- makes my head hurt.  Next off, black holes are not necessarily 4D.  They are huge stars that collapsed, and, fueled by their increasing gravity, condensed into a density so great that they are... well, black holes.  Just as another way of saying that, the space-time continuum makes a huge 'dip' there, like a well.   Next, a 3D printer would have to make all the little parts INSIDE of the stuff to make a good prototype.  That's not really physically possible unless it also assembles stuff, too, but besides the obvious difficulties in that design, I'll let you figure the rest out.  Whew, finally done.

And here is where we find topics becoming flame wars: any topic in which there is not sufficient evidence to accept any of the sides as fact. Personally I think we should drop the subject, as it does not relate to the original discussion.

I agree.  The discussion is about 3D printing - please don't turn it into a philosophical debate on the structure of the universe 

The concept of printing microchips and such sounds kind of far-fetched to me; I imagine that instead, you'd go to a phone (or whatever) store, purchase the internal components (battery, screen, et cetra), and then plug your own materials (or theirs for a fee) into the 3D printer and print the rest of the phone with your own modifications.
