DetailsSteel nozzle! Meant for printing abrasive materials.
compatible with printers with M6 threaded nozzles such as E3DV6 including:
Raise3D N1, N2, N2 plus
Ultimaker UM2, UM2+,
Ultimaker UMO (need to modify or remove fan shroud so it doesn't hit bed as nozzle is shorter than shroud)
Printrbot UBIS 13 compatible
Is much stronger than a brass nozzle. The downside is slower printing speed due to the lower thermal conductivity of steel, compared to Brass (about 60% copper).
The JET RSS have a revised tip angle, revised jet shoulder width and revised internal geometry, with a gentle slope leading down to the exit. They are also slippery inside, due to a special treatment. These new nozzles are meant for Speed! Plastic will flow more easily than in most other nozzles. Atomic pulls work very well! The inside geometry makes it much harder for plastic to “hide in the corners”, so changing color/filament type will be quicker and safer.
WHY JET RSS? – If you print a multi-hour object with an abrasive material using a brass nozzle, you will experience that the nozzle wears down while printing. This increasingly affects print quality until it becomes unbearable.
