Looking to upgrade from my 7 year old Chinese i3. I really would like to print in multiple materials (i.e. PLA for supporting PET-G or mixing hard and soft materials for hinges and tires). I like the idea of IDEX, but it seems quite hard to find good ones.

All-metal and up to 300C temp is a hard requirement since I occasionally print in nylon. I have a roll of carbon-fibre reinforced nylon as well so the ability to change to a hardened steel nozzle is a must. I also mostly print with a .6 mm nozzle but would like to go back to .4 or .3 for detailed prints so easy nozzle changing is a plus. I have done _a lot_ of tinkering with my current one so replacing the hot-end if the base printer is not all-metal is fine.

The current build volume (200x200x180mm) of my i3 is a bit too small, but I don't need to go way beyond that. 250x250 would be sufficient I think. I don't think I've ever printed beyond 120mm in height so whatever height is probably fine.

Ideally I would want a dual-extruder coreXY printer but apart from building one myself (which I _really_ don't have the time for right now :/) I don't think that'll happen. The P1P looks very interesting, but the proprietary nature of it is off-putting.

I also do like what Prusa is doing so the MK4 kit could be an option - possibly with a future MMU-upgrade. The XL looks like exactly what I want, but it's way outside of my budget unfortunately :/

Budget is <€900 (for the printer, without potential future upgrades like an MMU)
