The Ultimaker 3 has everything - from reliable, repeatable prints to impressive dual extrusion, except for one thing; abrasive materials. Enter the HardCore Print Core from 3D Solex - an Ultimaker 3 Print Core with hardened steel nozzles in multiple sizes. Print support material faster with the included 0.60mm nozzle, or utilize the wear-resistant 0.40mm for a longer-lasting nozzle over it's brass counterparts. This kit includes 2 nozzles and everything required to change between them.
The nozzles included with the 3D Solex HardCore Support Core feature a slippery coating that prevents any filament from sticking to the nozzle and degrading the quality of extrusion or clogging the nozzle. Having accurately printed support material is important in order for it to provide adequate support for the rest of the print. The benefit of a larger nozzle size is the ability to print faster, but with slightly less definition. This is perfect for support material because surface definition isn't important to the success of the print.
The number one rule when changing 3D printer nozzles is to always do so with the hotend heated. Trying to change nozzles cold will always lead to broken components and broken hearts. Changing nozzles on the HardCore Print Core is interesting as you need to have the print core removed from the machine to do the swap. Here is the procedure for correctly changing nozzles without damaging any components:
