Features

  • Drop-in upgrade: FlowTech hotend is designed to be an easy drop-in upgrade for each 3D printer model. This updated edition is designed for Creality K1 / K1 Max and K1C . Stock z-height, build volume and firmware remains unchanged.
  • Leak-Proof Nozzle: Tired of messy nozzle leaks that ruin your prints and waste filament? FlowTech Hotend combines nozzle and thermal break into one permanently sealed assembly that ensures a leak-proof hotend.
  • Cold Nozzle Change: Swapping out nozzles used to be a time-consuming and potentially hazardous task. With a FlowTech Hotend, nozzle changes are effortless, and there's no need for hot tightening, and you can do it with just one hand.
  • High-Flow Characteristics: Ceramic cylindrical heater and 28.6mm melt zone provides excellent volumetric flow rate.
  • All-Metal Design: Built to last! FlowTech hotend features an all-metal design that can handle most modern 3D printing filaments. The entire hotend is machined and assembled in-house, with quality control performed at multiple stages during the manufacturing process. At the end, each hotend undergoes a full thermal cycling test before it is packaged.

  • One of the best and easiest upgrades you can do.
So, when I got my new K1 Max, I was ecstatic. From opening the box to my first benchy...less than 45 minutes total. Now...there was NOTHING wrong with the printer AT ALL. It's a phenomenal machine right out of the box. But...I wanted to make sure I had replacements "on hand" for the inevitable. That included a replacement hotend. I did order a replacement direct from Creality, but then started reading about MicroSwiss and all the other print fanatics out there with their reviews. So, I decided to bite the bullet and order one of those the K1 Max as well...and a hardened steel 0.4mm nozzle. When it came to replace my first hotend, I skipped the stock replacement and decided to throw this in first. And I have not - ever - been disappointed. This thing really is great! Is it better than stock? Maybe? I am not a "print-head fanatic" by any means, so I never got into EVERY single aspect of this. All I know is that since I've changed it out...I've only had issues that were on ME (or filament)...never with the hotend. It prints flawlessly...every single time. It's quick, maybe even quicker (higher flow) than stock, but I've never messed with max flow rate. All I know is I can throw anything at it and it just prints. I only print PLA and PLA-CF, but even then...no swapping, no clogs, no stringing...nothing! Now, I do have some fat fingers, so trying to get it installed - only because of the tiny pins on the printer itself - was just a bit tight, but installation was straight-forward and easy. And, just having the option to do a COLD swap - if and when needed - is just icing on the cake. I've purchased several other hardened steel nozzles just to have - another 0.4mm and a 0.2 for finer details - and just got the diamond tip from MicroSwiss itself...again...just to have. That original nozzle in the FlowTech hotend has nearly 1,000 hours on it now, and it's still as good as the first day I dropped it in. ... show more

  • Finally NO MORE. CLOGGED NOZZLES
Got tired of the periodic clogs and finally made the switch. Easy easy install no clogged nozzles since, seems to produce better quality prints. So I am happy

  • Great replacement after I mangled the original.
While trying to clear a clog on my K1 Max, I managed to mangle the hot end. after looking for a replacement, I settled on this. Installation was easy, with the only problem being confusion on my end WRT which hot end I was replacing. since replacing it, I've had about 20 hours printing PLA & PETG w/o any issues. ... show more

  • It's ok
TLDR: Check to make sure your nozzle is tight after two hours of printing. I have battled all sorts of strange issues with this hotend from bed scraping, prints failing, and clogging to over extrusion. The problems were intermittent and would happen on some prints but not others and occurred after roughly 3 hours of printing with this Micro Swiss replacement. I went through all of the normal checks, bed leveling, PLA swaps, different prints, extruder replacement, etc., etc. When I finally gave up and decided to swap back to an older hotend and nozzle I realized that the nozzle had worked itself free by about 3mm. This would cause the nozzle to have about 1.5mm of travel which would cause all of the intermittent issues. I cranked the nozzle back into place, ran a test print and my printer is back to printing beautifully. I’m guessing that after a few heat cycles the nozzle’s expansion and contraction caused rotational-loosening. I hope this helps. ... show more

  • Best upgrade for your dollar
Started with this on my K1 and didn't appreciate the value until I seized a nozzle in it 7 months later. I replaced with the supposed unicorn hot end and was so utterly disappointed that I went back to microswiss after a week. The creality unicorn hotend dropped flow for petg by 50% and caused excessive stress on the extruder. And on top of that. Creality only offers hardened steel unicorn nozzles. So to hell with that garbage. This is the single best improvement that can be done for the K1 series. It's far better quality, far better flow, and provides consistent pressure advance response through fast even filiment heating. And you have a large selection of nozzle options allowing petg to be printed with the ease of pla. No stringing, no clumping, no failures. Once you calibrate your printer you will have the confidence of knowing it will not fail from print to print and roll to roll. You want numbers for petg. Microswiss 250mm/s print speed and 19mm3/s flow with a standard brass coated microswiss nozzle. Creality unicorn nozzle is 125mm/s and 9mm3/s max flow with clumps and strings on top of it. There aren't enough words to praise this product. Pictured is a voron cube scaled to 150% printed with standard polymaker petg at 250mm/s and 250C temp. Perfect layers, Perfect overhangs, and perfect bridging. ... show more

I’ve had more clogs than successful prints since switching.

  • Great Hotend!
Upgrading my Creality K1 Max to this Hotend has been a game-changer! I originally had repeated nozzle clog issues, ended up damaging it trying to remove it from printhead. That’s when I decided to upgrade to this Hotend. I haven’t had a clog since. The cold nozzle change feature has made switching nozzle sizes so much easier. I love how the high flow rate has sped up my print times without sacrificing quality. I highly recommend it if your having the same issues with your K1 Max. ... show more

  • Drop-in replacement. Excellent flow. Feeding new spools easier now.
The product is a straight drop-in. The install sheet and the linked video both does a great job of showing you what is needed. I had the newer K1M with a hotend that had the blob of death. Do yourself a favor and remove the glue properly without wiggling and applying force, you don't won't to break the connector off the board. And that's nothing to do with this kit, that's just cause Creality glues these connectors not thinking about future service needs. Immediately could feed my PLA+ from Elegoo and had it printing reliably again from the very next print. Already order more for my other K1Ms and Elegoo Neptune 4 Max's. Great job Microswiss! ... show more
