Right now looking into bang for the buck workhorses with a small footprint/build volume. A description that fit the Prusa mini+ perfectly in the past, but it feels like Prusa is a dinosaur that hasn’t moved with the times.
So who is still buying the Prusa mini+ and why?
Personally: While Prusa has outstanding support, good data protection, and does good things but there is now the Bambu Lab A1 mini.
Prusa mini is at the moment 500€ plus 20€ for a filament sensor (sic., it’s nearly 2024 and that’s an paid upgrade on half a grand printer) and another 7€ for WiFi.
Bambu Lab on the other hand is 320€.
Looking at the specifications, the A1 looks like a clear winner: For maintenance, there are three tasks: 1. cleaning and lubricating the mechanics (both are the same in this respect); 2. cleaning the build surface (both are the same); 3. maintaining the hotend and here Bambu Lab is clearly the better system as you can replace the nozzle in just a few seconds compared to Prusa’s E3D v6 hotend, which requires hot tightening.
The operation is not that different. Both support network, web interface, and automatic bed leveling probed at the nozzle. Bambu Lab has a camera built in, but this requires the printer to be connected to the BambuLab cloud, which may not be possible as the model data is shared with/uploaded to China. I would say this is still a strong point for Prusa as privacy is not an issue with their printers which means they can be easily deployed.
Performance should be close with input shaping enabled, but the A1 mini has the higher flow rate hotend, which means BambuLab is once again the winner (still no highflow at only 28 mm^3/s but twice the flow of a Prusa V6).
The build volume is identical and the footprint is also almost identical, so again no point where Prusa beats BambuLab.
Value? I have already mentioned it. 1.6 Bambulab for the price of 1 Prusa is a clear answer. If Prusa still had the 400€ original launch price and a filament runout sensor included, maybe the answer would be Prusa due to privacy/easier integration. The 200€/printer price difference is so significant that I don’t see who is still buying multiple Prusa mini+.
Btw. is there another printer on the market that just works paired with a small footprint and excellent value?

I have no experience with either of the two.
I did however buy a Prusa MK1 ten years ago for 650€. It has since received the MK2 conversion from 3mm to 1.75mm, plus autoleveling. The heatbed needed a new connector at some point, and I’ve enquired about old STLs to replace some parts. It’s still running great to this day, and support has been excellent.
If it ever gives up, I’ll go with another Prusa.
When it comes to my decision making for what printer to get, while the price does matter, what is more important to me is being able to maintain the printer for a long period of time.
And I am not talking about right here, and now. There are a lot of parts for the Bambu A1 mini on the market today. I am talking years from now when the printer is considered old and obsolete, but still does the Job.
Prusa has a proven track record of not just providing parts themselves for their older printers. Going so far as to even offer upgrade kits for previous printers. But also using off the shelf components, making matienence a non-issue for me, even if Prusa was to get wiped off the face of the earth.
Meanwhile Bambu doesn’t have that track record. And being, yet another Chinese Company, making an injection moulded machines using closed source firmware, and non-standard parts and tools to cut the costs down to be competitive. They’ve yet to prove to me that they will support their printer beyond when they are selling it.
Take for instance the most use and replaced part on a printer, the Nozzle. The Prusa Mini’s nozzle is just a standard E3D V6 nozzle with hundreds upon thousands of spares of various quality available online. While the Bambu Labs A1 mini is a proprietary affair that includes the heat sink, that’s only available from Bambu today.
Will someone make a clone? Who knows, but Bambu certainly hasn’t built the trust yet to make me confident that they will. Or will open up the designs when they inevitably chase the next shiny, and drop the A1 mini for… let say the A2 mini, which might have an entirely new hotend assembly.
I wasted my Money years ago on a Flash Forge Adventure 3, a printer which killed itself by breaking it’s X-Axis motor wire. I was out of warranty, there was no replacements on their website, and to even access the motherboard, I had to completely disassemble the printer. For $25 dollars more I can get a guarantee that not only my printer will work, but is repairable and will continue to work for years to come. I think I will pay the extra $25. Honestly I spent an extra $300 CAD to get a MK4 over the P1P for this reason alone.
I guess it’s people who care where the products they use are made.
I do care and that’s why at 400€ I would go with them but with 320€ vs. 520€ you have to put a lot of emphasis on this point.
As compromise to split it between Prusa and BambuLab isn’t feasible either. You want a standardized setup to keep it simple. Meaning all Prusa or all BambuLab.
Yea Here in the states the prusa mini + is $480 with the filament sensor.
The a1 mini is $300. Or $460 with the ams lite.
The a1 mini is $15 to ship while prusa os $45-66 depending on what I want
Also bambu is avaliable at microcenter by me while I dont k ow of any store that sells prusa here.
The new a1 is even a better value. $400 or $560 woth the ams lite vs the prusa mk3s at $650 for the kit or $900 built
I can get the a1 + A1 mini for just $50 more than the mk3s kit.
I’d love to support prusa but maybe they should think of opening a branch in the states or team up with a retail partner
Personally, a 3D printer that has to be connected to a cloud would be a hard no. Even more so when that cloud is located in China without EU or US oversight.
For what it’s worth (annecdotal and n=1 and all that), my Prusa mini has been absolutely flawless for 3 years now. I would buy it again even at a higher price point than the current.

I don’t see why a 3D printer in particular would be a concern, unless you’re prototyping stuff for a business and worried about proprietary commercial stuff getting out.
But I’m amazed that people in general are willing to connect their systems – 3D printer or anything else – to an outside provider’s service. It has a considerable number of drawbacks.
-
It punches a hole in what is normally the front line for home computer security, the firewall/NAT device. Most setups default to not allowing inbound connections. Now you’ve got some device that is opening connections outwards and could talk to other systems on your network.
-
It permits the manufacturer of the device to change the terms on which I can use the device. Maybe down the line the manufacturer of your smart TV – who is not getting any revenue from you after the initial sale of the device – decides to start inserting ads, say. This sort of thing has been done before. I want the manufacturer’s interests to be aligned with mine. Before the product is sold, they have to convince me to buy the thing. Afterwards, those interests could diverge. I don’t want the manufacturer to be able to alter the terms on which the product I bought may be used if our interests have diverged.
-
Even if you want to trust the manufacturer’s intent, can they secure their own system against people with more malicious aims? If someone can break into that, they can affect all of the customers, which may make it a tempting target. Russian intelligence attacked Viasat satellite modems, using an exploit that they’d clearly found earlier, when Russia invaded Ukraine to try to disrupt Ukrainian communications. They pushed a firmware update to brick modems. They didn’t even just impact systems in Ukraine, but also some outside, like a German offshore wind farm’s control system.
-
If any functionality depends on that manufacturer staying in business and being willing to keep paying for the operating costs, that seems fragile. Many companies do go out of business or decide that the costs of operating a service aren’t worth it.
-
Just being able to track someone’s moves across IP adresses has some value; reselling that information helps deanonymize people. Could happen down the line if a company is acquired by a larger company that data-mines its logs.
-
If you lose Internet connectivity for any reason, you lose local functionality. Home automation stuff is a particularly egregious example – you don’t want your light switches or climate control to stop working if you don’t have Internet connectivity to somene’s cloud service. But it’s true for any number of things.
I agree with all you said, but I think a 3D printer is actually a special type of concern next to generic cyber security and privacy, because it can affect the physical world. It’s not unthinkable that the machine can remotely be told to heat up beyond safe levels and as such create a fire risk. Not the type of device that should have an open and active connection to a server somewhere far away in my opinion.
Oh, that’s a fair point, yeah, I suppose that anything where only software avoids some kind of catastrophic physical failure does legitimately have its own risks.
-
I will just put in my 2¢. I maintain 3d printers for a local library and while the 4 mk3s+ machines have been solid the Mini+ has been nothing but trouble.
First we had issues with the extruder, then the Bowden tube kept causing jams. Replaced that but still have a ton of stringing with the default Prusaslicer profiles with every kind of filament we have tried.
And honestly having messed with both, the additional space needed for a “full size” printer is marginal once you factor in the spool holder.
Prusaslicer is amazing. The MK3 is/was great. I don’t know how much I love Bambu lab but the Prusa Mini was not great.
My big two gripes with Bambu are their software (just let me use Cura, I got experience with that and I can use it across printers) and their proprietary shit. Swapping pieces costs a lot, and they also seem to break extremely easy which makes me costly replacements extra annoying.
I haven’t heard they break easy. What more can you share?
I actually do like the Flashforge Finder 3, which comes with a direkt extruder and filament sensor at a price of 300€, works out of the box and is incredibly easy to use. But i wouldn’t consider this as a small build volume or a small printer.
Don’t buy Flashforge unless you want to hate your life. They were the first printer I ever bought and unless things have changed they use a proprietary slicer that’s years behind anything else, and they will claim it works with other slicers…until you discover you need to figure out all the settings yourself, including start and end codes
To be honest i am very happy with the printer. It works perfectly fine with cura, at least i have never run into a problem with it.
