This fantastic newly developed product by 3D Solex has a core of stainless steel and a multi-component molecularly interlocked tempered surface with 3 main advantages:
1) PLA ( or any other filament we know of ) is hindered from sticking to it.
2) Cold Pulls work so much better, the inside of the nozzle is “ICE” too.
3) Its surface is much more wear resistant than that of stainless steel, so it will last much longer printing abrasive filaments. Compared with brass, – it is in a class of its own.
It also works exceptionally well with chemically challenging chemicals, like glow, flexible materials, + many more.
These are the three fantastic advantages of this nozzle.
Now blobs of filament will not be carried around and deposited on your print.
Downside: A stainless steel based nozzle will not allow you to print as fast as a brass one, it is about 1/3d speed.
Use: Run-in period of 2 hours at max 220C. This hardens/tempers it, after that, Max temp 270C.
For HardCore Pro for UM3 only. This nozzle can not be used with any other system,
It will last much longer with abrasive filaments than the original nozzle.
