Here are my 6 recommended 3D printers, selected from the nearly 100 machines I have tested:
auroratechchannel.com
Welcome back to Aurora Tech Channel. Today, I will be reviewing the Kingroon KP3S Pro, which is an upgraded version of the old KP3S and is similar to the Prusa Mini. They are both cantilever-style printers, where the X-axis is only supported at one side, so they generally have a smaller print volume; the Prusa mini is a 180 cube and the KP3S Pro is a 200 cube.
Let’s take a look at the hardware of this printer. It uses linear rails on the X and Z axis, but the Y-axis uses rubber wheels. You can order an upgrade kit, but we will talk more about that later. It uses a Titan-style single-gear direct drive extruder with a 3:1 gear ratio, and the hotend is a modified V6 style with a PTFE lining heat break. It has belt tensioners on both the X and Y-axis and a 2.4” color touch screen. It uses an OEM MKS Robin nano motherboard with TMC2225 silent stepper drivers on all axes. By default, it comes with a glass bed, but you can pay an extra $10 to upgrade to a smooth PEI print surface. It has no auto bed leveling sensor so leveling has to be done manually by adjusting the knobs underneath the bed. The retail price of this printer is $209. I would like to thank Kingroon for sending me this machine to review, and with that, let’s get started.

Wow you have a string of budget printers that are really pretty good for the money. There should be a lot more young engineers in 2023. Thank You so much. Great Job. Dennis

Great video. You and your brother put so much effort into every video. Your evaluation is unbiased, even though you get the review units for free. Pure professionalism. Looking forward to the next video. Happy Holidays, Merry Christmas, happy Hanukkah to those who celebrate. May 2023 be filled with much better things than 2022 was. although I did manage to buy 5 new 3D printers for my business.
I am new to 3d printing and while researching best choices, I found your channel and it's awesome, unbiased and professional. Thank you for your efforts, Merry Christmas, good luck with your work, and looking forward to see more reviews.
nice review once again great job always love watching your videos :D
excellent, i really like that you catch 'issues', and show 'fixes' that you come up with. super-valuabke for a 'beginner's (like me!)
I installed marlin to mine and it made EVERYTHING so much easier. The stock firmware sucks, but once you get marlin on it, it's great. Even mesh leveling is better.
Thank you for the comprehensive video. Happy x-mas is
thanks for all your reviews. I actually like using Kingroon filament I hadn't realised, I needed some black and when I looked at the last spool which had been good before ordering, it was Kingroon
have a merry christmas & happy New year
Love your reviews! I printed you spool holder with the handle and love it! Thank you.
First mode, Fit a silicon sock to the hot end. KP3s was naked and wasting heat out the box. I will say though, The only issue mine gave was a stripped thread on the Z coupling so the bed wouldnt rise, After a quick check over That screw was replaced with one 5mm longer and everythings been printing nicely. This little beauty prints well, Faultless benchy (apart from the seem, that i could have lost in the slicer. Well worth a go.
I am surprised that they did not send you the all linear rails version to review.
IMHO, linear rail on Z is crucial too. As the rubber wheels will some times hit a "bump" in every rotation, that might be because of the low quality bearing inside. On my elegoo neptune 2s I often have Z bandings that are 72mms apart, due to the low quality wheels. The wheels are 25mm in OD, and the part that touches the rail is slightly narrower than 25mm, giving a 72mm diameter.
As far as i know it's supposed to come out in february.
To be honest, i don't think loosing 15mm in Z is such a big problem. One could probably fix it with a few printed parts as well.
Excellent . Thank you so much.
Man I always look forward to your reviews! Before I buy a printer your my go to and I always suggest everyone who wants to get into printing to check out your channel! Also Merry Christmas! If you don't celebrate Christmas sorry and Happy Holidays ❤️
Hmmm... I've been looking for a small parts printer and this looks very good for the money. Great review!
Holy scat... absolutely not worth the headache. Great review, you might've saved my wallet
This vs the sovol sv06 you reviewed recently?
Another great video!
For the money it seems pretty great
I think it actually makes sense to use it on xz, y probably needs two and z has leverage on it.
The bed issues are a shame tho
Great Review. I am just wondering whether it is comparable to ender. Please share you thought about whether should I choose ender over this in similar price range
What was buggy? The motherboard or the firmware? How about adding insulation to the heated bed? What new features did the firmware update offer? Do you think it's possible to use a text based screen instead of the graphical one?
It would be interesting to see how much you can speed up the print speed since it has linear rails and direct drive.
Great review. I recently got the S1 from Sliceworx. Same experience with heating and leveling. I also moved the filament up top, with modified roller holder, but haven't moved the sensor yet. I'm not a fan of the glass bed. (I already ruined it, removing a print pulled the finish off, haha.) I don't get the point of those tnuts, but whatever, it works.
Looks like you might have to open that configuration file in UTF8 or unicode, I'm assuming it compiled fine after editing?
Did you encounter any difficulties in installing y linear rails? Mines arrived wobbled and also the aluminium bars where not straight... At the end solved with 2 rubber rings between the new plate and the y Rails.
That's what I like about Aurora, she can outline something on what she prints and any model on what, in principle, she cannot print.
Is this printer not running Marlin? Since it is mentioned to run a board similar to the MKS Robin Nano, I would have expected it to be fairly easy to build a custom Marlin for it with all the options you want. Or ... add a Pi Zero 2W and Klipper (probably making the screen useless, but getting so much in return and controlling it via your smartphone.
Hi. Great review as always. Can you get baby stepping on the standard firmware?
Thank you for an amazing review! I have a KP3S and I'm interested in this one. One question: would it be possible to add the E3D Revo system to this printer? You say the hotend is a modified V6, so I'm not sure if the Revo Six would work there. What do you think?
Thanks again!
The E3D v6 is shorter. You will need to print another fan duct. Everything else is fit perfectly.
Hi! Where can I find the stl file for the BL touch mount ? Thanks And thanks for the great videos.😃😃
@AuroraTech.... Question for you 2. I was thinking of buying a PrusaMini+ but after watching your video I was thinking of maybe getting this printer. Considering I can buy 2 of the Kingroon KP3S Pro S1 for about the same price as the PrusaMini+, Would you say it is a better overall deal to pick up 2 of these? I would like to slowly build a print farm and these look like they might be a good fit. What is your opinion ? TIA and keep up the great videos you 2.
This printer is good and fun to play with if you have some experience to fix minor issues and know how to avoid the buggy firmware. But if you want to build a print farm, something like the Ender-3 S1(or S1 Pro), Ender-5 S1 that requires no tinkering or additional upgrades would be a more reliable option.
Glad you were not too hard on bamboo.
Do you have the stock firmware config file? I have the S1 and can't find the stock file anywhere, specifically for the Pro/S1.
Hi I have been following you for a long time and I find your reviews excellent and useful and today I wanted to ask you to give me your 3D printer preference for 2023 thanks
It would have been cool, if you had compared this Printer to the Tronxy Crux 1 you reviewed some time ago. I think this would have been very interesting for people who can't decide wich low Budget printer to get
Agreed. The Ender 2 Pro went from my list pretty quick. Crux 1, KP3S Pro and Prusa Mini is where it's at.
I love my crux 1, at first I didnt and it was because of the all thread heat break but after upgrading it to the one tronxy sells for 15 dollars Its never loosened again on its own due to the set screws now instead of a lock nut. Ive printed at 150mm a bunch of times, just need slow first layers
do you have link for new firmware? my KP3s Pro tend to stop in the middle of printing, and restart
Helios can really jam on the piano eh! ;)
Seems like a no-go machine until the "PRO" upgrade is truly pro. For now I'll wait
Thk u ❤️
I have a feeling with the limited knowledge I have with upgrades and such I should steer clear of this one and stick with some others you have reviewed at a little higher cost. Btw idk if its a different mic but it sounds like you may have been under the weather lately? If thats the case I hope you are feeling better.
Yes, I lost my voice last week and getting much better now, thanks
Where did you get the file for the 3d touch mount? I cant find it online and my sd card was cracked when I got it.

I have 2 issues with this review:
1. No mention of ringing
2. ABS needs an enclosure, and printing ABS open frame results in bad fumes and bad layer adhesion.
But aside from these issues, I think this review is good.
Not to mention the hotend is PTFE lined11, and you shouldn't really go above 230 degrees with it or you might get off-gassing.
@@CurlyTop1492 It is supposed to be safe up to 240c
Great review, it definitely needs some polish and I don't think that it can beat the Ender 3 at this price point but it has lots of potential.
Do you plan on reviewing the pro s1?
No, it just the same as the KP3S Pro but came Y linear rails preinstalled, the print quality and the performance would pretty much the same.
My gripe with their printers is you always have to upgrade something. In my case, their KP5S didn't come with an auto bed leveling. I think Auto leveling is a requirement for large bed printers. I had to install it, and update the firmware which wasn't easy to find btw. And now my screen goes blank during printing and I can't access the menu during the print. I have to reboot the machine after each project. This is so annoying.
I'm seeing the same issue with this KP3S pro.... For a machine that uses the word "PRO", I would've imagined the rails were already upgraded to linear. Magnetic Bed would've been nicel. Auto bed leveling would be good, but not necessary for a small bed. However, buying all these upgrades, it would cost me around $300 total. So instead, I bought a different printer with all those things I wanted for $300 and I don't have to mess with it.
Fair enough. But i think you don't need to upgrade. She was able to print a benchy without any updates.
If you have a glass bed, ABL isn't really needed i think, regardless of the size. Once dialed in, it works until you change the print surface or location of the printer.
PRO is just a marketing word. These machines are not made with European or US quality standards in mind, the end stop screws for example wouldn't fly here. A Company that does it's business like that would perish soon. If you want quality, you have to pay the price and go to Prusa, Ultimaker or someone like that.
The rails are just a gimmick, in my mind they aren't better or worse than OpenBuild rollers.
@@citronski
I prefer the rails. It doesn't necessarily make the prints better, but the maintenance is simpler. My old CR-10 and Ender 2 had the rollers, and i always get paranoid that the screws will loosen and start to wobble. And they seem to wear down faster than the rails from my observation.
Glass beds work okay, but I prefer the magnetic bed. I don't have to wait for the bed to cool down to remove prints. If the glass had a consistently even surface, then i would probably use that over magnetic beds.
When I first bought my K3PS. I really loved it. Small, accurate, and durable especially for the price. I expected that they up their game with the newer K5PL and K3PS Pro, but it doesn't seem like it's any better. I'll gladly pay the extra $$$ for properly upgraded versions.....
Ever think about building a voron v0.1?
Before Bambu Lab exists, I might, but now, I don't think it is worth the time and money to build it when you can get something that even better for less money.
Shame about the heat bed. Is the power supply weak maybe?
I ordered one for 205€ start of December on their webpage, with Y-upgrade and PEI. They said they send the Y-upgrade and PEI sheet from China, which i though wasn't a problem. The Printer itself was supposed to come from an European warehouse. They don't seem to react to my messages and haven't sent me any updates since. I'll soon start a Paypal dispute.
I wish this would be something TH-camrs would talk about. Having the printer isn't all, it's also customer support, ordering, payment and people you can contact if something goes wrong.
Same here. Anyone knows anything about orders of December from the oficial webpage? Thanks for the video Aurora
@@frange I have asked via Paypal, what is going on. No reaction. Started a dispute.
Also ordered a SV06 to keep me entertained.
Hi, can you give a stok firmware for this printer?
Hi, do you need a firmware can you give?
seems like getting a refurbished ender3 s1 from comgrow is a better deal.
For the most part refurbished is a better deal regardless of the printer.
👍🏻👍🏻
I just can’t imagine buying a 3D printer in 2023 without an ABL sensor. Especially one with a spring bed.
I don’t see why you would need it, especially on a printer this small. I have 5 printers and no ABL, but once I level them I’m good to go.
@@jeffreyepiscopo I agree, ABL is nice if you change build plates or location often, neither of which is my use case. No need for ABL really.
I also like the older 12864 RepRap displays more than touch screen.
ABL causes more problems than it solves.
@@petercallison5765 I have a Tronxy X5PS with a 330x330mm print bed. ABL is a must there.
But i agree with you with small printers.
Pretty disappointing number of QA issues. I get that it's a $200-250 printer, but basic stuff like bad filament path and bed heating failures make it feel more like a refurb Ender 3, in terms of experience, if not worse.
This. Chinese can't do quality. Look at this, look at Bambu Lab X1. I'm not sure why, but i have yet to see a company that offers European or US quality.
@@citronski what's the problem with the X1? Heard of Kickstarter backers getting flaky units, but that they fixed those hardware issues once they hit mass production. I know the software for the X1 has been a disaster, though.
@@theglowcloud2215 You have to tinker to keep them running and that is a nogo if you need them for production. We have 5 of which 3 are down as we speak, waiting for replacement parts.
We learned a lesson: If you need to rely on 3D printers to meet any kind of deadline, skip China made printers.
@@theglowcloud2215 I'm not against 200€ Chinese made printers at home however. You know you get a tinker device, you know what to expect.
@@citronski What parts failed?
The lack of baby stepping is enough to cry about
Is your health ok? your voice is different
wish you are ok
Can we just call it PET-G instead of pee ee tee gee? 🥺
I find this expensive for what you get on this printer
Crux1 is better
Had nothing but problems with mine, going back to Amazon.
