Proposal Type:



Hardened steel nozzles for the 3D printer

Submission Date:


Current Status:

Awaiting Approval


Kit Wallace


Currently with a brass nozzle fitted, there are restrictions on the filaments which can be used with the new Prusa I23 printer. Fitting hardened steel nozzles would allow it print abrasive filaments such as glow-the-dark, wood- and bronze filled filaments and carbon-fibre (as well as non-abrasive filaments).

Proposed Purchase:

Suitable nozzles are available from E3D

or the slightly more expensive Nozzle-X

Proposed Installation:

Suggest that the hardened nozzles be fitted by a maintainer (ie Nick!) as standard since swapping nozzles is a tricky procedure.


1 steel nozzle @ 0.4mm nozzles = £18 + p&p


1 nozzle-X @ 0,4mm = £27 + p&p

In general, nozzles are the only wearable part and might be considered to be consumables
