These brass nozzles are individually turned as part of the main production process, not just die casted like budget models.
They are extremely precise, well machines parts that will out last other products.
The standard nozzle diameter that comes with the machine is 0.4mm
Please specify what hole size nozzle you would like.
If you do not specify, we will send you a 0.4mm nozzle.
Use a 0.4 if you want precision, but as you go larger, you will be able to build the model much faster.
A 0.8 mm nozzle on average can finish the build 6 times faster than a 0.4mm!
But also remember big nozzles mean less detail in the model, so do not use them for minute things or you will not be happy with the performance.
You need to adjust settings in your software to ensure you print with the larger sizes properly.
Please remember that nozzles can not be swapped after being used.
Please choose carefully, we cant refund or replace a nozzle once it shows even the slightest sign of use.
Please remember that nozzles can choke due to contaminants.
A brand new nozzle may print for 5 mins & choke if you are loading anything contaminated into it.
This is not a fault in the nozzle, but rather contaminants in the filament or dirt or known additives (like carbon fibre) that are choking the nozzle.
Such issues are not part of the warranty & do not qualify for a replacement.
