These are genuine stainless steel nozzles for the Formbot 3D printers, compatible with both the T-Rex and Raptor series. These nozzles are unique in their shaping, with a very flat end to ensure a solid locking fit with no filament leakage during print.
The stainless steel nozzles are more rigid nozzles that are able to work with more aggressive materials like metal and wood based filaments, but do not print as fine as their brass counterparts.
These nozzles are available in 0.25mm, 0.4mm, 0.6mm, 0.8mm, and 1.0mm sizes.
