In the new generation of our printers, we use special nozzles with all-metal filament guidance. This means that the entire filament path through the Nextruder is all-metal, with no PTFE tubes anywhere. This increases the overall reliability of the printer, and nozzle replacement is much faster. If you have your favourite V6-compatible nozzles, you don’t need to worry – we offer a simple Nextruder-to-V6 adapter.
