Switching Dual Input Single Nozzle Bowden Hot End 0.4 / 1.75 RepRap 3D Printer.
This hotend is high-quality all metal (no plastic/PTFE parts in hot zone, except for thermistor wiring insulation) dual input, single output hotend.
Printing with a Switching-Hotend is an exciting new frontier, although software and electronics setup are fairly simple and we are seeing great results. This hotend takes some extra learning and getting used to and may require a little tinkering and tuning to get awesome prints. If you’re looking for a more conventional system then dual input/dual output of the hotend may be a better fit for your needs.
