The default nozzle diameter for most FDM printers is 0.4 mm, and Snapmaker’s nozzles used in A150, A250, and A350 are no different.

Our nozzle is MK8, M6 thread. Please make sure that the nozzle you choose is the same type.

We have not tested any nozzles of other brand, so we do not know the compatibility between the 3D printing module and other nozzles.

In the near future, we will release more options of nozzles with various sizes so that you can use a smaller nozzle for more detailed (but slower) prints, while larger nozzles for faster prints.

If you need to replace the nozzle, please refer to the following tutorial：
