A collection of some classic Lemmy memes for your enjoyment
An open source 2d printer is possible but will probably never happen
The print head is incredibly complex, the drivers and communications to talk to printers are all closed source, and unlike 3d printing the level of quality people are accustomed to is covered by patents for another 20-30 years
Are you saying the very concept of high resolution 2d printing is patented? Or that the way so and so manufacturer does it is patented?
IANAL but I think patents don't necessarily mean open source isn't possible.
