Is it possible to make a 3D printer yourself?

Question

3D printers

Interested in the issue of self-manufacturing electronics for a 3D printer.
In particular, I am interested in making a shield for an MMS card and a screen with control buttons for RAMPS1.4

Answer 1

Well, it goes without saying that it is possible?
It is not clear why.
If you just need cheaper, then now in Russia they sell models for assembly inexpensively www.electronshik.ru/card/nabor-komplektuyushchih-d... 17,317 rubles. and also a kind of "do it yourself"
If you are interested in your own development (as I understand it) - then it is logical to take a ready-made board, Raspberry Pi or Arduino, this will allow you to drive RAMPS1.4. Since you are writing about the screen and control buttons, it will be easier to implement it on Raspberry Pi and similar boards.
