We went from fax paper, to printers, to color printers, to laser printer etc?

From personal record players to, casset tapes, cd, flash memory, etc?

With 3d we went from plastic 3d, to high detailed and faster 3d, and now some people are doing metal 3d printing, and organ 3d printing which is interesting and strange.


So what steps would it take to make 3d printed cell phone for example fully assembled to print at the same time any material, color, texture, etc?

To even be able to print a spool of copper wire would be impressive enough but still what are some thoughts on the next step of 3d printing? I would assume less messy printing/more accuracy, Color plastics, mixed materials, etc. And the time it would be to reach 2 materials being used, who knows.

3D Printing with an insulator and a conductor at the same time seems very beneficial to the research going on here.  Imagine 3D printed motors and circuit boards.  Take it to the next level and imagine silicon transistors, diodes, carbon resistors, high Q capacitors, inductors, everything printed in one-shot.  Self contained energy generation devices saved in a file and distributed via the Internet as OpenSource.  Wouldn't that be something to see.  Maybe in our lifetime, who knows...

A funny point I am making which might need to be for another topic but since this one kind of set it up is the evolution part.
What is the time line for it evolving in how long it will take.
Do things stagnate when no new technology is present? sometimes
Should people see a chart to see the big picture to see what is next? I think so.
It is not only what is the next step, but what process leads to the next step and the steps after that.

How can one find what number is after 1 when their is no numerical order, what comes after A if no alphabetical order, Of what is after hydrogen if no periodic table. Try stating all the numbers form 1-10 without an order and pattern to see if you can do it as fast. I tell people go ahead try it out and EVERYONE can not go as fast or as accurately state them all despite its only 10 numbers. As just like that inventions take a while since their is no order of progression.

We can theoretically try to count to infinity till out hearts are content, or at least count to 100 easily. We can say it is so simple and obvious how something evolved by knowing the history of it, but to continue to state what is next and how to get to what is next is not so easy, when we do not know where we are going or the pattern how we got here so well.

Every thing you can think of in a chart, everything that can be made in a chart, or everything that can be predicted in a formula with its odds and probability. Maybe some charts can not be put on a 2D chart and might need 3D as another post points out.

I think inventing is not hard if one knows what they are doing with the proper understanding and formula. The thing I wonder is if it does happen will the person be a prick and become power hungry and greedy. I can't think straight to give an answer, maybe someone else might. Or maybe I am wrong and people just move on.
