Looking to buy
I'm interested in experimenting with inkjet print heads: mounting them on a CNC machine to make a flatbed printer, alternative inks (eg., bioprinting or UV-curing inks), building my own electronics to control the print head, that sort of thing. Could you help me choose a good place to start? For example:

- I hear print heads are typically either thermal or piezoelectric. Sounds like piezo would be more versatile for alternative inks
- A line of print heads that's been around a while, so that I'll still be able to find parts a few years from now
- No DRM shenanigans where they're working against the owner
- Bonus points if there's pre-existing work where people have already documented interfaces or built driver boards. I've found a few, but they're for pretty old heads.

My plan would be to buy a (hopefully inexpensive, but doesn't have to be) printer and start experimenting. If it turns out that heads for real flatbed UV printers are also available then that's interesting too, but my guess is that they'll be prohibitively expensive.

........- I hear print heads are typically either thermal or piezoelectric. Sounds like piezo would be more versatile for alternative inks.......
For modifying an inkjet printer to Direct To Garment or Printed Circuit Board flatbed printers Epson is the preferred brand as their piezoelectric print heads can handle the special inks used for these purposes. Thermal print heads as used in for instance Canon and HP printers cannot handle the special inks.

I don't know if the Epson print heads can handle UV curable inks.

Some also modify 3D printers so they don't have to build a CNC machine from scratch. Here a 3D printer is converted into a milling machine by replacing the 3D print head with a Dremel or similar. I think an Epson print head could be attached in stead of the Dremel making a CNC printer.

Good luck with the project and please report your results.
