To explain what I'm trying to do a bit more, here is an overview of my ideas in this case.
As far as I understand so far, it's technically possible to create complete PCBs including chips, memory and screens with inkjet and or 3d printing and the right inks. Graphene seems to be a non toxic wonder material for this.
I am not an electrical engineer or a skilled programmer so my understanding of the limitations here is very basic.
The most promising examples I have found are these here:
print a working paper computer https://www.newscientist.com/article/mg22029374-500-print-a-working-paper-computer-on-an-80-inkjet/
printed 8-bit microprocessor: https://electronics360.globalspec.com/article/4824/8-bit-microprocessor-opens-path-to-organic-iot
Printed paper memory https://www.nanowerk.com/spotlight/spotid=36722.php
Printed tft Screens https://www.youtube.com/watch?v=2qg5BXH1mPs
I have been trying in my spare time to find simple DIY instructions so that I can start experimenting with printing usable electronics at myself.
By this I mean complete circuits including the microprocessing units. I love sites like Instructables for DIY things like this, but the best example I found there was an inkjet printed circuit with no processing capabilities. http://www.instructables.com/id/Print-Conductive-Circuits-With-An-Inkjet-Printer/
I know companies like PragmatIC are already quite advanced in this department. They make RFID tags, printed displays NFC, powered devices.
The instructions I have found on this topic are all very technical research papers that are mostly beyond my understanding.
I need the "How to make an inkjet printed computer - For dummies" Version.
Any links pointing to simple DIY tutorials would be greatly appreciated. With all the amazing posibillities in this field I imagine there must be a large community like this somewhere that I have not been able to find yet.
If further clarification is wanted please let me know and I will try to explain what I'm looking for better.
Thank you for taking the time to read this. I hope this is not too off topic for the site
Thanks to all the answers I am now realizing that none of these examples actually have inkjet printed processors.
Thank you all for pointing that out. I see my question should be about how to print transistors/processors.
Printed transistors apparently are possible, but as I see now the company in that paper seem to be the only ones claiming they have printed a processor and I'm not finding any further evidence yet
