Micro Swiss All Metal Hotend with Slotted Cooling Block for Wanhao i3 w/.4mm Nozzle

Its working like a charm. Easy to install. After doing a PID tunning with Octoprint i have not had any issues.

A huge upgrade over the stock hotend. This allows printing of high-temperature materials, but also allows significantly higher print speeds due to the all-metal construction having better thermal conductivity. The slotted cooling block allows tight clamping on the heatbreak, which gives better thermal contact. Definitely worth it!

All I can say is that this is the best upgrade I have made to my 3D printer. Besides the ability to print more exotic filaments that require a temperature above what the stock hotend can provide, the print quality on my printer has greatly improved. Following the instructions as provided on the Micro Swiss website, the installation of this hotend took me about 15-20 minutes and was rather easy to perform. By looking at the negative reviews of this hotend, I can tell that those reviews are the people that have not followed those instructions resulting is clogs and misprints. However, if you follow those instructions, this will be the best $50 you will spend for your printer.

After burning my pfte tube, I got this as a replacement for my monoprice i3 plus and it works flawlessly! Just make sure you follow directions step by step and you should have no problems. Also, make sure to adjust your retraction settings. For PLA I used 50 mm/s retraction speed, 0.6mm retraction distance, and 20 mm/s retraction prime speed.

Perfect this part turned my really good budget printer into an awesome budget printer. The workmanship on the part is top-notch and the installation kit/instructions worked perfectly. Highly recommend adding this upgrade to any Wanhao i3 or the clones out there.

Easy to install using the online instructions. This Micro Swiss All Metal Hotend has printed every filament type I have loaded into my printer, including PLA, PLA+, PETG, TPU, NinjaFlex, and probably others. I did install this with the MicroSwiss all metal extruder plate. I totally satisfied with this upgrade.

best upgrade for the wanhao duplicator i3 plus!

I did not expect much when I order Micro Swiss, especially after reading so many complains in forums when peoples Wanhao i3 with plastic leaks, clicking, jamming stories. I was a little bit scared. However, the original extruder finally starting to mess up my PETG prints big time, I knew that it is time to move on. To my surprise, the installation went smoothly. Very little efforts needed if you follow Wanhaos YouTube disassembly video. After that I screw the nozzle in, backwards 1/2 rotation and install the block. 10 min later I am ready to print. The first print, I use 10mm/s speed. Then in the next project, I use 20mm/s, and then 30mm/s and then 35mm/s on PETG and all of them are successful prints. No more wasting plastics and the model came out much more strong than the original extruder! I do not understand how it is possible but it just does! Do not hesitate if you want to print PETG, it works great!

So far this product has worked perfectly! At first I was skeptical because I heard about clogging issues on some forums, but I have had 0 clogging issues so far. By the way if anyone is wondering this is compatible with the Monoprice Maker v2 (Which is a clone of the Wanhao i3 and not the mini.)

Works great with Monoprice Maker Select V2. Took me about 30 minutes to install. It would only take about five minutes, but I didnt adjust it to the right height the first time. It prints PETG with much better quality than the stock Maker Select hotend and nozzle.
