No, 2d printer tech is fine. It’s the ink scam cycle for them that are the problem. There’s literally no functional reason they couldn’t all use the exact same few cartridges. Capitalism ruins everything.

I once had to boil ink cartridges

In my 10 years of being a High School Robotics teacher i find that my group has less problems with the 3d printers than the 2d printers.

The irony is that making an Open Source 3D Printer is far more accessible and affordable than making an Open Source 2D printer.
