The blue tube in K1 Max

I just bought a new K1 Max, but found out it didn’t come with the small blue tube, I asked the seller about that, and he said there are new editions without it. Is that true?

If it has the unicorn nozzle the tube between the extruder and the heat break is apart of the nozzle.

It indeed came with this tube, but I didn’t install it, isn’t it a spare nozzle? I’ve printed a few prints now, but afraid about the blue tube.

The upper part of the nozzle is the replacement for the Capricorn PTFE (blue tube) it goes directly to the bottom of the extruder drive.


The Unicorn nozzle replaces the nozzle/heatbreak/blue PTFE tube as a all in one part, this was to prevent leaks and some jamming issues.

The printer has a built-in nozzle, should I replace it with this one? Or is the built-in also a unicorn nozzle and no need to replace it? Sorry for these stupid questions, I’m new to 3D printing and this is my first 3D printer.

Yours should have the unicorn nozzle system already in it. The newer models have that as standard equipment now.

The extra nozzle might be a steel tip one you could use for printing Carbon or other highly abrasive filaments.

The one that is installed is brass for PLA and other non abrasive filaments.

I can’t thank you enough.
Thank you all!

This was a very useful thread as the documentation doesn’t have the extra nozzle in it and I was also mystified as to what is inside it and what’s in the box as extra.

As a follow up question can the hardened steel tip be used for all filaments then? such as the easier stuff like PLA… or do I need to always swap?

I use the hardened nozzles for everything

You can use the steel nozzle for all filaments but things to keep in mind:

:white_check_mark: You might need to bump up the desired temperature as the thermal conductivity for steel is different than a brass nozzle.

:white_check_mark: The steel nozzle might take a little longer to reach your set temperatures.

I always watch the temperature graph in Creality Print. It tells me how well the thermistor is controlling the temperature and how long it takes to reach a temp setting.
