Noztek have introduced a new pre-heater band for the Noztek Pro and the Touch extruders. This extra band adds a number of benefits to the single nozzle band. It ensures the polymer is molten after it leaves the hopper which will prevent jamming and also removes most of the strain on the DC motor increasing the longevity of your machine. In testing the Noztek Touch with a 60 RPM motor, under load will run at 60 RPM with the extra band and 50 RPM without.
Depending on the polymer you’re using, you should see up to a 50% increase in filament production with this additional heater band
