WANHAO FlashForge Builder Hotend Nozzle Review

I've been using them in my Flashforge Creator Pro for a little over 3 years and the performance is great. A must-have upgrade over standard PTFE tube nozzles and much better finished than cheap alternative all-metal hot ends. Finally, I recently had to replace one after a print came loose from the bed, covering my heater block and badly clogging everything with plastic. I really just needed a new nozzle, but regular nozzles don't work - they have an internal cone designed to mate with a thermal

It was easy to install if you take your time. I learned the hard way that this doesn't work with stock injectors. After installation, everything needs to be recalibrated, especially temperatures. The instructions state that PLA requires a much higher temperature. I've found that temperatures between 10 and 40 degrees Celsius give excellent results, even with poor quality yarns. I also found that my firmware does not allow operation at higher temperatures. A quick update solved this problem. The

However, I recommend that you DO NOT USE THIS FOR PLA PRINTING. There's a reason your 3D printer came with a PTFE hose and not a solid metal tip: it's because the PLA gets too soft to feed properly without it. So if you're primarily using PLA and only have one extruder, don't buy an all-metal hot end. This will jam up your extruder and ruin your…
