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

Best upgrade you can possibly do for your Wanhao i3 or monoprice. Been using it for about a month now and Ive been able to print tpu nonstop now as well as wood pla with no clogs.

Very good

This along with some unrelated soldering has drastically changed the quality of my prints for the better. Super easy to install too

made all my problems with printing PETG go away.

Very nice and well made. My prints have a nice sheen in PLA with this hotend.

Worth every penny. Im printing PLA on the Maker Select Plus. Install this and calibrate your e-steps for beautiful prints.

Im really happy with this upgrade - the stock heating block doesnt seem to hold a steady temp well, and this block preheats in about half the time, meaning Im ready to start printing far sooner. The fact that it has replaceable nozzles is icing on the cake.

Upgraded to this set so I dont have to worry about PTFE liner decomposing. Install was a breeze but of course I broke one of the heating cartridge wires - my own fault, be careful when you do it. Print mostly PETG on Maker Select V2 with stock stepper and D4 drive gear, 0.25mm layers with 0.4mm nozzle at 60mm/sec head speed. Calibrated ESTEP at 3mm/sec which gives me a bit of a headroom for my head speed. It extrudes reliably, probably can push it even faster. Good experience so far.

I bought two of the cheaper knock-off all metal hotends you can find here on Amazon. In both cases I had trouble with heat creep causing clogging after several hours of printing PLA at 200 degrees. In one case I purchased a new nozzle and heatbreak from the same supplier as the knock-off hotend, and the nozzle was so poorly machined that it wouldn’t extrude at all. The .4mm hole was almost completely occluded with metal. Perhaps a drill or machining chip? Then I bough the Micro Swiss all Metal hotend for my Maker Select v2 3D printer. Should have bought this to begin with. My son has been printing Mandalorian armor almost non-stop for a week. 20-26 hour prints. Not a single clog or air print. Works like a charm! I don’t know what all the differences are, but Micro Swiss has something the knock-offs don’t have. It just works. First of all, the steel lower section is tightly fitted to the aluminum section of the heatbreak. The top hole, where the filament enters the hot end, is deeper and smoother making it easier to feed new filament in. The nozzle is clean and well made. The inside also seems smoother than the others. I’m very pleased with this hotend. I wasted over $50 on the knock-offs. Wish I had just bought this one instead. Lesson learned!

So far, so great! Get this kit, not just the all-metal tube and nozzle version. The block is much better than the stock version on my monoprice.
