Eh, I see it as Prusa gives so much back to the community so I'd rather support them over a Chinese company pumping out clones with no innovation.

Glad to see your good results with your Fysetc clone, definitely a testamant to just how polished the MK3S is as a design. I own two clones, one from Trianglelab and another from Blurolls, as well as a genuine kit from Prusa Research. I am planning on adding at least a Fysetc one as well as a colored Sealand/Blurolls frame kit to my farm. Long as you understand that you may have to replace some parts on your own they'll assemble just fine. That said, if I hadn't bought my genuine Prusa first, I would've never known what to check for on my clones to make sure everything was being assembled correctly. Run Sunon fans if you can from the start and definitely just print the PETG parts yourself as even Prusa's own farm parts leave a bit to be desired. And if you can, do Paul's silicone bed mod to ensure a super flat bed, genuine or clone. It's basically the nylock mod but better. Also stock up on those POM/Delrin leadscrew nuts and linear bearings, especially the leadscrew nuts if you're prone to destroying them like me.

In my experience I ended up liking my clones better just cause I knew what parts I was throwing into them and the fact support was on me. I also had a pretty bad experience with Prusa Support that led to me lone wolfing my genuine MK3S. My Trianglelab clone has more hours printing than even my genuine MK3S and I had the genuine one the longest so make of that what you will.

I did hear the Fysetc clone ships with a PTFE 4.1 bore hotend which if that's the case is just plain stupid. I am running Trianglelab's pre assembled V6 clone specifically for the MK3S on all my kits and as far as I know they are all metal from factory.

For those saying the clones rip off Prusa Research, well the design is open source and the license specifically allows clones like these to be sold legally.

Overall, great video and I am interested to see if you'll be reviewing the Bear frame clones or other vendor's clone kits such as Trianglelab and Blurolls/Sealand in the future!

Mad assembly skills there. Well, editing skills.

Since then I have just found out that there is a hidden easter-egg "Experimental" menu in the new Prusa 3.9.1 Firmware where you can set up an "ALTFAN" (alternative fan option, because of the Noctua supply shortage the original Prusa had to deliver 3D printers with other fans also) which slows down the nozzle fan RPM and at the same time it makes the 3D printer more quiet. I will make a short video about it, but you can also try it out when you go under Settings -> HW setup and roll down to the bottom and push the knob around 3s. After it the new menu will pop up at the very bottom. Could be that it wont make any change first just after you restarted the printer. Tell me if you managed it.

Thank you for the side by side comparison of the two printers.

Outstanding video. I wish it had existed when I originally purchased a clone from Fysetc. I later bought an MK3s kit from Prusa. The clone has worked fine, but the assembly was challenging. Too many of some screws and nuts, not enough of others, no 3mm filament for the extruder cable support, a few other things that I have long since forgotten about. Both of my printers get used a lot. If I prorate the additional cost of the Prusa against the savings for the clone - especially after the E3D hotend and fan upgrade, the savings in price is negligible.

I completely agree. If this is your first build and you can afford it, buy a Prusa. You won't 2nd guess your decision later.

I already have a resin printer but also wanted a FDM for larger prints and was thinking about the Prusa until I found this video. Thank you! I will be ordering it as soon as I have time to build it!

I came to the same result as you.
I did the following changes to the clone:
1. original PRUSA fans
2. Original PRUSA Hotend (E3D V6)
3. Original steel sheets (smooth/coated)

everything else remained untouched.
Print results are equal as you mentioned.

But for unknown reason, if I need something, I always start the original PRUSA, I don't know why, but I do :-)

I don't mind paying for more for an original prusa. But man their lead times are horrible. If you want to pay more you expect great service but also decent shipping times. Your review makes it tempting to go for such a clone.

[macdorus]

The quality of this video is excellent, it's exactly the comparison I was looking for but I did not expect one so well made. It is clear, goes in depth, no annoying/unnecessary parts and a great chapter system.
I will for sure check out the rest of your channel, keep making great video :) !

Suspect the faste fan makes the temp sensor have an offset on the clone. That would explain a lot of the things seen together with the voltage levels. Would be cool to see the voltage measured by a separate instrument.

[BeefIngot]

Thanks for this. This might be the thing that tips me over the edge.

[hansratzingerselbstandiger]

Many thanks! Perfect testing setup. Your results fits to our experiences with Prusa clones in our Maker space.

[HASSTL]

Watching your content is very enjoyable, your profromance is outstanding

[maltoNitho]

And to think just the other day I was thinking about getting another Prusa...but now I might two or three of these!! Tyvm. Sub’d.

[jamesball]

Thanks for taking the time to make this available to the community.

[chaosfreak]

Great video. I have ordered the clone mini and it’s fantastic. Prusa mini original will arrive in December.
Prusa mk3s bear clone will arrive next week.

[shotbyarian]

can not decide which one to buy, so tempting!

[paudiaz]

I bought one of these instead of the trianglelabs one thanks to this video.I just finished the assembly today with my own printed parts in PLA exept for the extruder and the board case wich are PETG. Definitelly buy your own M3 *8mm screws, this is NOT OPTIONAL. I almost ruin the Z motors because of that.
The bearings I got were fine but you might get bad ones.
It worked perfectly once assembled, didnt even got that weird upside down LCD cable problems.
I didnt even needed to calibrate ther machine, not even the ESteps.
I already have an Original prusa mini and print quality is identical.

Honestly, its a great machine, I didnt expect it to work so well. Also is my first printer kit and it was super fun to build.

Nice explanation between the 2 printers, at home I have a MK3S and a mk2.5s printer. I was looking for some info of the fysect version but I couldn't get some clear answers until I stumbled upon this video ^^ good job!
