How come there are no open-source 2D printers?

We have all this open-source hardware—3D printers, soldering irons, single-board computers, and even some phones.

But there’s still no DIY/open-source printer that lets you use any ink without hacks or tricks, one that’s easy to upgrade and expand, without forcing you to buy all kinds of proprietary nonsense. Why?

I wish I had enough knowledge to start such a project. Hopefully, one day I will.


Let's start a discussion!

What do you think are the biggest challenges in creating an open-source 2D printer? What solutions could help overcome them?
