Hot-Ends review


Prusa Nozzle V1 One of the first single piece stainless steel nozzles - The original V1 nozzle was right on the edge of thermal design. without exactly the right amount of barrel cooling I found even the slightest insulation around the heater block could cause problems with flow when extruding PLA, leading to stalls or jamming. With too much cooling a similar issue could happen where material, especially when being retracted could cool too fast and jam in the barrel. The V1 design could also be driven at vastly higher temperatures (+280 Degrees C) to extrude PLA at amazing speed, I eventually ran out of extruder performance to go much higher than around 180mm/Sec print speed, but the nozzle was still capable of faster speeds. When it’s setup well, this nozzle could extrude at the fastest rate (0.6mm nozzle / 3mm filament) using the 2finger test, and with minimal pressure applied.

Overall opinion and general recommendations: 1. No longer available. 2. Use the V2 nozzle.
