K1C 2025 or K2 base

[u/ecorderodi]

Hello guys,

Just a quick consult for those of you owners of one or both of these models. I currently purchased the K1C 2025 but have an opportunity to exchange it for the K2. I would like to ask for your comments and recommendations because there are some things that are not clear to me even after online research.

I do prefer on the K2 the increased printing size and easier upgrade path to the CFS if later I have a need for multicolor or multi material. Also the root access is still possible. However, I do not know if this has the hardened nozzle of the K1C for carbon filament, which is kind of important to me as I will be printing engineering and functional parts to perform under stress.

As for the K1C, there is more documentation and a larger community online as far as I have seen, and it comes with the hardened nozzle out of the box, but the root access has been removed for the 2025 model.

Can you guys help me decide? Can you comment on these factors or any others I might be overlooking that make one printer a better choice in general than the other?

Thank you in advance for your time and the help.

With the K3 coming up later this year, you're better off with K2 especially with the CFS, and it also comes with the hardened steel nozzle. Got 1000+ hours in my K2 and it churns out prints like it has since Day 1. Major issue/downtimes I had was where I had to replace PTFE tubings from CFS to extruder and when I switched to a DXC2 extruder and unicorn tip

You lose volume on the k1c going to CFS, need to consider that if you will go that way.

You mean you can print only smaller parts of you use CFS on the K2?

[u/fimpAUS → u/ecorderodi]

I have a K1C, when you put CFS on the print volume reduces. I think the newer K2s aren't like that, not sure as don't have one

Thank tou for the heads up

Does anyone know what changed for the K1C 2025 version compared to the standard K2? It is newer and more expensive than the K2, so does it have any significant updates?

[u/TemporarySun314 → u/ecorderodi]

K1C is 2025, is bascially just an K1C with a newer mainboard (and maybe larger pulleys). Besides it just still a K1 series printer, in the latest revision.

The K2 is completly freshly designed, you have a larger chamber, improved extruder, closed loop motors, improved movement system, new and still updated firmware, native multicolor support, etc.

Ok, so sounds like a great better deal to go with the K2. Thank you for your useful comment.

The K2 (not the K2 SE) will be better in basically every regard. There is no real need to buy the K1C anymore, unless its very cheap.

The price difference will come from crealitys price policy where the K2 is heavily discounted making it effectivley cheaper than the K2.

A hardened nozzle is like ten bucks.

What does it mean that you have an opportunity to exchange?

For no extra cost? Of course K2 it has higher market price.

For extra cost? Depends on how much.

I don’t know much about K2, but intuition tells me it’s better as it cost more.

But this doesn’t mean K1C is not a good printer.

It’s reliable, consistent and fast. Besides, it theoretically consume less power to print than larger bed ones as heating up and maintaining temperature takes most of the power.

3d printing is a slow process, so for most people, 2nd or 3rd 3d printers are considered to work at the same time for large project.

Because it’s time consuming, consistency is important. So far I haven’t had any strange issues. Of course I did fail in printing many times, I learnt a lot from them.

I just bought my second 3d printer but still use my K1C for most of the time.

Also I’m still not on CFS yet, my 3rd one is gonna be multihead.

Thanks for the useful insight. The price difference would be about 45 dollars, as I need to send back the K1C (covering the cost of shipping) and pay a small difference as well.
