Why a mk4s instead of a Core One?
There's a lot of right answers, but a QIDI or a Core One would probably be my two options here.
You mentioned an IDEX, are you interested in multi material, like combining PLA and PVA, or are you interested in multi color, like with an MMU?
I mostly print PLA and I don't care too much about print speed, so I didn't think the core one will really bring much advantage.
As for looking at IDEX, it's more because it looks really cool. I'd like to be able to combine pla with tpu or petg, but realistically I don't think I need it enough to justify the cost. I'll get a lot more use out of a multi colour system like an MMU.
As a bit of Prusa fan boi myself, I too would recommend the Core One over the Mk4s at this moment. It's a matter of "Buy once. Cry once." Cheap often costs more in the long run.
When you are facing a 30 hour print or a long project, a bit extra speed is not only nice but helpful. Plus the heated enclosure can provide access to more engineering grade filaments. While you might not need to print nylon or ABS every day, you will probably find you are going to want to at some point a bit of those types for a project or two. And I believe the Core One also has filtered exhaust air to control nasty fumes that FDM printing can cause, (yes, even PLA has particulates that won't kill you immediately, but they ain't good for you either long term).
Personally, I find the MMU to be a god awful design mess. A rat's nest of loose tubes and spools of filaments, but it does work. I might consider the Box Turtle over the MMU just for the neatness of the design. I find the multi-filament units, cool for very little color printing I do, but it's the ability to use up spools that don't have enough left one them to complete a print by switching to a different spool that can finish the print automatically to be far more valuable. It's cut down my clutter of mostly used spools to near zero. I paid for all that kilo, I'm bloody gonna use it all dammit.
Thank you! I should convince my lab to buy the Mk4s to Core One upgrade kit, especially with the health aspect. It's a big lab with ventilation, most of my colleagues only print PLA, but we print a lot. The extra speed will make the mechanical engineers very happy.
Personally I'm starting to lean towards getting a small QIDI printer now, and build a Voron 2 next year with hopefully Bondtech's prospective INDX. That would be the perfect setup for me.
Honestly, my second choice from the Core One would be the Qidi Plus 4. I wanted the X-Smart 3 180^3^ sized printer as a second machine. But it was discontinued before I got off my butt to buy something. (I ended up with a Bambu mini combo as an impulse buy). But if I was starting over with my first printer, I would seriously consider a Qidi machine.
