RE: Prusa MK4 vs Bambu?

I'll *probably* go MK4 and stick with single-filament (unless the MMU3 really impresses).  Multi-material is really a nice to have more than a necessity, and most of the options are rather crude.  The AMS *appears* to be much more refined, but there's appeal to "hey I melted this part of my hotend, can someone reprint it?" 😀

Looks like this was a great head-to-head......if only I could understand it!!

Looks like the first layer put down by the MK4 is better then the X1C?

RE: Prusa MK4 vs Bambu?

I have both printers and I agree with the prior review.

One thing I could ad is the noise, I'm a modeler and I do other stuff in the room where my printers are, the MK4 i can live with for a few hours when it's printing, if the Bambulab is printing after an hour it gets very  annoying.

How the sound bothers you is different for everyone.

In the end for me there both good printers and while speed is nice as a hobbyist it's not the most important thing.

RE: Prusa MK4 vs Bambu?

The decision today is not as clear as it was 5 years ago. There was Prusa and some cheap copies (Enders is a different story). I did choose quality and never regret the additional money (even the expensive MMU did work for me). Now there is this nice looking and good performing Bambu. Why do I stick with Prusa?:

- I knew every screw and can easily debug and repair things on my Prusa MK3. The internet community is very helpful and special spare parts are not needed.

- Update (HW and SW) works @ prusa. 

- I'm looking forward to new features, because the new controller board has much to offer.

- There will be second source for the new prusa design nozzle. I'm looking forward to the quality of the filament tips (hoping that all metal will improve it and will work better together with the MMU)

- noise is an issue

- I do more care on quality than on speed (not saying that Bambu makes bad prints).

- I stick with a trusful supplier and I'm not always looking for alternative solutions (the same as for printing material)

Finally: my Prusa MK3 works and works and works!

RE: Prusa MK4 vs Bambu?

CNC kitchen recently released a video showing some details of the MK4 and also doing some Bambuu comparision, which I found quite interesting:

The decision really is not that easy. I am still waiting for my XL preorder or news on the XL that do not convince me to hold on to it, so I am already debating what other printer could be used then instead... Times were much easier some years ago ^^ (which basically is a way of saying: Great competition and great new features are coming our these days)

RE: Prusa MK4 vs Bambu?

The review was pretty good.. I do think that Prusa should have rethought how they presented the 20 minute bench info. In no way was it clear that this performance was not immediately available.. and the whole thing surrounding compensation is still confusing to me. If they are not providing accelerometers.. and are doing a ‘generic’ calibration model, I question why they have not released that now. At least some beta profiles.. get feedback from users.  There is more to this than I understand. So right now it is only a 15-20% improvement over the MK3 and so I will take a ‘wait and see’ attitude. My MK3 works fine. Didn’t they release the mini with the Ethernet port not working.. and, I might be wrong, but I thought it was about 2 years before that firmware came out of beta. And I really don’t want to upgrade my MK3 to 3.12 quite yet.. So I hope they beef up the testing and speed of firmware releases. Although I *do* think the Prusa Slicer product has been outstanding. Every bit as good as the reliability of the MK3.

RE: Prusa MK4 vs Bambu?

They should have clarified that, the benchy g-code on the X1 has nothing to do with the stock X1 settings either though. Yet, the Mk4 as it is now is substantially slower than the X1. We are clearly still missing the input shaper implementation. If it is a proper one, the Mk4 should be able to get fairly close to an X1 though.

It is good to see that the Mk4 does print at top nodge quality though, better than the Mk3. Granted this is only about artifacts but it is something I would expect of a printer launched nowadays.

RE: Prusa MK4 vs Bambu?

As and X1C and MK4 owner - proudly a big fan of both - that video does a disservice to those that really want to know the differences.  I love my MK4 for what it is and it will be my reliable go-to for single-color, slow but great quality prints.  But the X1C is super fast at the same print quality and the AMS is an amazing leap forward in MMU.  Yes we have the MMU3 coming, but as it's largely built on the same cludgy MMU2 design, my hopes aren't high for that.

Again, great video to highlight and cover the MK4 but did himself a huge disservice by only mentioning in passing all the benefits of the Bambu.

RE: Prusa MK4 vs Bambu?

Yeah.. he overemphasized buying the Prusa because of the philosophy of the company. While I laud the open-source nature and great support of Prusa, ultimately the performance of the products will determine how successful the company will be. Look at the closed garden of Apple and its success. As I mentioned in a prior post, I am helping a friend build an 1/10 RC car and one chassis part took me 6.5 hrs on my MK3S. His took under 3 hours and there was no performance degradation at all (on his X1C and we haven’t even tinkered with anything but the stock profile.. it can go faster).. . So if you are using these for education or if you do large projects, speed *is* important as long as quality doesn’t suffer. I will also add that my friend is super impressed by the AMS. He loves just putting the spools in and then deciding what to print .. no fuss.. and after I’ve shown him color change by layer, he is even more impressed. The AMS will require more TLC, but it is pretty good compared to issues I’ve read about the MMC iterations.

I think it is a fair review.  It is harsh in some locations.  Appropriately, it brings up my same concerns about the Bambus I own.  I really do like my Bambus, but they are not replacing my MK3Ss or Mk4 (when it comes).  Bambus are supplements and use additions to my print farm.

But quality does suffer at those high X1 stock speeds. Not so much the appearance, but for technical prints the performance matters probably more. The differences between fast prints and slow ones goes beyond shiny and non-shiny surface appearance. Especially layer adhesion can go seriously southwards. Given that the X1 also lacks a proper high flow hotend assembly, as CNC kitchen itself has shown that stock X1 profiles print faster than is good for the printer and on the edge of what the hotend can properly melt. In these circustances substantial reduction layer adhesion can be already expected. 

Granted, with more moderate speeds which are still beyond Mk4 stock settings the X1 could propably print without major compromises in material performance but then the advantage dwindles and if you are printing for technical purposes you might not care about ghosting artifacts. In that case the Mk4 will probably have no difficulties to reach the same speeds too, even as it is, without input shaper. It will be also easier to install a CHT nozzle on the Mk4 with the official adapter than some custom Ali express 3rd party CHT clone nozzle for the X1, to prevent heat transfer limitations at higher speeds.

Jo Prusa talked in a video about a highflow version of the Nextruder heater block and nozzle, that he expects to double the melt capacity.

I assume, maybe the release of input shaping for the MK4 is delayed until this block is available,
also to prevent users from running into layer adhesion problems when printing fast while using the currently shorter blocks and nozzles. 
Users always blame the printer first...

 

Anybody considering to buy a Bambu printer:

Very important components of these printers cannot be repaired by the user.  They cannot be disassembled and the components are not available as spare parts.

Especially the design of the carbon rod axis and the bushings sliding on these rods will limit the lifetime of the printer.

Make sure to read the "Banding/Ringing thread" in their "Bambu Lab Forum".

It tells also a lot, that no Bambu employees engage in this thread... They often do in other threads.

It better not be. It was marketed as a feature of the current MK4. I wouldn’t be at all happy if I’m then told I need to purchase extra parts, or upgrade the printer to a ‘MK4S’ in order to use a feature that was promised by default.

RE: Prusa MK4 vs Bambu?

Considering whether to ditch my MK4 Kit order and just go for a Bambu P1P. Although its proprietary, even as a new company they seem to have things running much more smoothly then Prusa. Above all else, at least I know what I'm getting with that printer from the moment I unbox it, rather then promised features with no timescales.

Actually you don't. Print performance of the X1 is well known by now. Durability, maintenance and self-servicability mid-term are in the best case big unknowns.
Of course, if those latter points aren't big issues for you, then the X1 looks like a great deal. While we have no long term data on the Mk4 either, obviously, we do have the track record of that printer series and long term experience with those and the company.
