Asked about opinion for bambu vs Prusa Core

I'm opening a topic that i always said i wouldn't touch. 😞 

First to clarify that i was and am until now a prusa customer. Mk3 to S to S+ - added bontech, mmu2, SL/CW1 to SLS1, XL5th first day preorder. I never owned or am affiliated in any way with bambu labs. And i spend a bit of money to similar stuff like xcarve, xtool, genmitsu so i do go around doing some market research about this stuff

Recently a friend of mine wanted an advice about his first 3d printer. The comparison was between Prusa Core one assembled (for 1350) and BLabs P1S AMS combo for 800E. Honestly i could find anything solid to justify buying a prusa.

Lets skip the speed and print quality since im fairly sure that he cant go wrong with either in that part

Features: BL comes , amongst others, with a camera and multicolor system thats proven to work extremely well. From what ive read anyway. My own opinion was limited to mmu2s which was .. terrible PITA and after a lot of mods went to OKish. But i clarified that mmu3 has positive opinions. And of course adds 400E to the budget. Also BL has a carbon filter to the enclosure while PC sais that is optional.

OpenSource and reprap. Lets be honest here. The reprap approach and the ability to print various parts of the printer it became very limited to prusa. Not a bad thing  but a fact. And even some parts you have to print them in nylon due to the enclosures. The opensource doesnt say much if what you actually want is a good tool and not to tinker with software.

Upgradability. He saw the price and asked that since it costs 640 E to go from the late MK3s+ to MK4 and 490 60 Core one how is any combination of the above or as standalones better that a brand new p1s WITH AMS for 800E. I smiled and said .. its an option. He replied ... is silly. I disagreed but could say more.

Parts. Come on Prusa. I took a look (first time) to how much it costs for a nozzle for a BL. BL puts a price of 17 E to a hardened steel hotend and 37E to the complete set including fan , thermistor and heater. Prusa is 22 for brass and 55E (again brass) respectively.

I live in Europe. BL gives Free shipping for purchases above 120E. Prusa just adds up with weight.

I don't care if they are made in china since prusa , "probably" imports electronic components from there too and before 2023 i dont know who their pcb and electronics manufacturer was. I have a japanese car. im not going to be picky about my printer. And im sure a lot of other people

Finally again the cost. Come on man 800 vs 1750. This is more than twice the price.

Im HONESTLY NOT trying to promote bambu labs. Im trully trying to find a SOLID reason to advice someone to buy prusa. I highlighted the "you can print parts of your printer" -as much as this is limited as i said before, the bed leveling which i love on my XL, the huge customer base, excellent slicer and workflow  etc. I was honest about the support and said that whenever the problem was solvable by the chat or a replacement was needed the approach was excellent but if you where redirected to email was rather patience tempering.I didnt answer about support on BL because i dont know.

I LOVE my XL. Even if at the start was frustrated with various , rather small problems. And still are about some things. But if multimaterial is not your thing im trully struggling to find a reason to advice someone pro-prusa.

AGAIN im not BL sales agent  or own anything else than prusa for 3d printing.

Any thoughts on the above?

RE: Asked about opinion for bambu vs Prusa Core

You make a number of very interesting points here, several of which I ask myself often.

It seems to me that there are two approaches to 3D printing these days, frst the 'traditional' reprap route where the hobby is effectively centered on the machinery and tinkering with and updating it. We tend to be very patient as we update and upgrade, for instance the joy of setting up my MMU3 was finally getting it to work as much as seeing a first mult- colour print. Prusa, for now, works well in this marketplace but it seems to me that, as awarness of 3D printing has spread, newcomers want another approach; that is to produce stuff without too much under the bonnet knowledge. Many of these people, I suspect, are happy to simply download and print stuff - I imagine some would even prefer files to be ready sliced for their particular machine. In this 'chalk or cheese' world Prusa caters to the printer centric group very well for now and as long as this group is around they will continue to thrive.

Going back to your original point, if a friend asked me for advice I would have to advise them that other approaches are available and ask them to consider exactly why they wanted a 3D printer and whether they were happy to risk being disappointed. I am very happy with my setup as it goes well with my needs and interests; I like designing in Onshape, I like visiting the mysteries of various slicers, I am enjoying  exploring 3D scanning and more. Unless a friend asking me for advice showed an interest in some of these things I would feel obliged to say that, in my opinion, a Prusa machine might not be what they are looking for.

RE: Asked about opinion for bambu vs Prusa Core

@brianjordan Just a comment on something that you wrote. There is a third approach... i believe... to the kind of users that go for 3d printing. The people that enjoy making stuff, designing and 3d modelling, either mechanical parts on software like inventor , solidworks etc or "artfull" using zbrush etc but want their 3d printer to be like their brush or saw. A tool. Something that will give them the finished product reliably and rather quickly. The first thing i acquired was a cnc cutter. It was made using mdf , angle joints and a second hand makita router. After a while i went with xcarve since i wanted to use the cnc for fabricating and not fabricating my cnc. In my opinion this is the majority now. Like the guy that asked for advice. He want to do a lot of stuff but wants to start printing them and not having to tinker the printer first. The "rep rap tinkerers" you mentioned i believe are going for vorons and ragrigs rather than prusas. Forgive me if i am wrong but Prusa core one, as nice as it looks, has no clear audience except loyal prusa customers. Is it a affordable reprap? No if you consider what you pay for a voron, ratrig etc and play with them. Is it a reliable tool just to do your job. If it is something like the rest of the line up...  SURE. But its expensive in comparison with other brands that fall on this category. The market now is not as it was 10 years ago that you had ultimaker, and then a lot of unreliable cheap ones. And then you had Prusa. With all the bells and whistles at an affordable price in comparison with the UM and a bit more expensive that any other brand with zero reliability. I dont know. I really want Prusa to keep making good printers and retain a place on market. And i believe  what it can  do that because of stuff like the tollchanger, modular bed etc. But if it keeps going down the path of SLS, Core and mk4, price/feature wise at some point it will loose some of its customer base.

There are too many threads like this demonstrating that many users have not done any pricing or care more about owning a printer as an ornament than actually using it.

Whilst we cannot be completely certain until users get their hands on them it's reasonable to expect the Core One to be at least as efficient as the Mk4 and it's upgrades.

For anyone planning to print multicolor the Prusa printers are cheaper.

How?

Here is a repost of a reply made last week in:  https://forum.prusa3d.com/forum/english-forum-general-discussion-announcements-and-releases/black-friday-or-should-we-say-price-adjustment-for-the-upgrades-for-older-printers

Purchase price is not a good way to compare printers...

At a recent event I got to chatting with a couple of other users over an overpriced sandwich and low grade coffee ... memo to self, always take a packed lunch ... we did some ballpark comparisons: (Prices at time of lunchbreak, they are all over the place at this time of year, but close to...)

Purchase:

Bambu multicolour ca £1000

Prusa Mk4+MMU ca £1300

Prusa XL5H + enclosure used *just* for multicolour ca £4300 (if for genuine multimaterial it's a no-brainer automatic win)

 

Multicolour printing waste:

Bambu wastes 2-7 x the model weight as 'poop' and tower. Lets assume 3x.

Mk4+MMU wastes 1 - 2 x amounts as tower. Let's assume 1.5x.

XL wastes about 0.5% as tower and about 1.5m of the end of each spool in the bowden.

 

Assume you wish to print 50kg of multicoloured things: Easily done in a year.

Useage:

So the Bambu uses 50 + 3*50 spools = 200 spools

The Mk4+MMU uses 50 + 1.5*50 spools = 125 spools

The XL uses 50 + 3 spools = 53 spools (Perhaps less)

 

Using reasonable quality filament at about £25 per spool that's

Bambu - £5000

Mk3+MMU - £3125

XL - £1325

 

So for your first year's production, ignoring all other costs assuming they are equal (they aren't but not very big differences) you have spent

Total:

Bambu £1000+£5000 = £6000

Mk3+MMU £1300+£3125 = £4425

XL £4300+£1325 = £5625

...and Black Friday sales are often disappointing, many companies, not Prusa, simply raise prices for a while in the summer so they can announce reductions in november. Prices are often lowest at the end of winter when shelves are cleared for the new year's stock.

Cheerio,

RE:

@Diem You do make valid points but if you consider mk4+mmu2 vs p1s+ams then the price is a bit different. BL combo is 800 and MK4S+mmu goes to 1500. Im using in my comparison the assembled version since BL is  assembled. Also BL comes with an enclosure (important IMHO and its 370E for PRusa) and with a camera (dont care much personally but is another 40E for a buddy cam). These are the prices with what are they posting today. As far as filament consumption for the multimaterials i cannot argue since i dont know but i can definitely agree with you about XL being in a different league. It should not be compared because if you want a true multi material the cost of mmu3 and ams is irrelevant.

Again it matters what you are. If you are a hobbyist and want to occasionally print multicolor then the cost difference that you save with mmu ,in a period of 2-3 years, is not so big. Keep in mind that if you are not looking at it as a investment then paying twice the price upfront it maybe more "painfull" than a long term saving per spool. And especially if you are someone like me that after a while i used the mmu2s mostly for spool joining rather than complex models with  multiple changes (since this would exponentially increase the time). If i was looking as an investment or running a company and was looking for multicolor options i would anyway skip anything else than a toolchanger. Even if we dont take into account the filament savings just the printing time difference between the two option makes it a no brainer towoards XL. And in a company that time save will bring me a turnover faster on an XL than on an mmu or ams.

As for saving on filaments. Until last year  , just before i got my XL, i was buying filament from Prusa. When i started playing with my XL and i wanted a lot of spools to play around i tried esun from 3d jake. Its 18E per spool and free shipping over 100E. That means i get 5 spools of petg and have some change left while for 4 spools of prusament petg i have to pay 107E+23E for shipping=130E (With this much money i get 7 spools esun from 3djake). I mentioned esun since i tried PLA,PETG and ASA on the XL and gives really good results for the price.  Resin i get from siraya tech. Why do i mention all the above. Because the market has grown a lot the last decade. A lot of companies have products that don't lack on quality and are very competitive in price. I mean i bought the SL1(turned it to S)/CW1 combo. But the curing station it costs 750E on its own. It cost more than buying a decent sla printer. And you can find an anycubic curing station (with less features but it does do what is suppose to) for 250E. And we are talking about a curing station not a printer. 

All in all you are right about a lot of things but  prusa must keep in mind that a customer is not going to weight how mush filament is going to save in 2-3 years but how much will have to pay now and what features does it offer. Upgrade kits are a big plus for companies that if they want to upgrade their farm will be able to save a lot of money (100E for each MK3S to MK4S) are a lot of savings but for me the cost to upgrade my mk3s to mk4s and then to core one would not be justifiable. But still its there. Thats one thing that other than repraps approaches like voron i cant thing of other companies that offer it. A big plus for prusa.

As i said in my OP im staying with Prusa for now but im finding difficult to convince an average person, that wants a reliable printer just to print stuff (she/he finds or designs)  and doesn't care to tinker with it, to go for prusa instead with a cheaper and as far as comments go reliable BL.

I must emphasise, the initial purchase price is irrelevant.

The correct condition of a 3D printer is ... printing.   If your biggest expenditure is not filament you are wasting money and resources.

Even if just a hobbyist you would be expecting a 25% - 40% duty cycle. There is little point in having a faster printer if your duty cycle is less and even then two slower printers are better than one fast one. These days I run an XL5h and a Mk3s+. The Mk3 is mostly used for TPE's as the XL has to slow way down for them and it's as convenient to use the old printer while the XL does something else.

a customer is not going to weight how mush filament is going to save in 2-3 years but how much will have to pay now and what features does it offer

I disagree, most makers are practical folk who make just those calculations. Most 'features' are just gimmicks - I did fit a pi with camera and octoprint to my Mk3 when new but removed them within a month as I couldn't think of any use for the pictures and remote operation is pointless when you have to attend the printer at start and finish anyway - dry filament always has to be loaded fresh so load, go away and start remotely three hours later is stupid

im finding difficult to convince an average person, that wants a reliable printer just to print stuff (she/he finds or designs) and doesn't care to tinker with it, to go for prusa instead with a cheaper and as far as comments go reliable BL.

Curious, I would say exactly the opposite especially for a designer who will inevitably design slower than they can print whatever they buy.

I am effectively retired and I don't print commercially but I do some designs for local workshops and boatbuilders on a swapping favours basis - I prototype with the cheapest available filament and switch to higher quality for finished products. One shop, and I anticipate a couple of others will follow, has bought Prusa to make runs of my designs.

The most expensive filament?  I prototyped a part for a large yacht using cheap PLA but designing for metal deposition which was then emailed to Gibralter for printing and fitting in either stainless steel or phospher bronze at a dockside cost of several thousand pounds.

RE: Asked about opinion for bambu vs Prusa Core

@Diem. As i said i agree with you at some of the points you said. Personally even if i don't print as a job i would never go for an ams/mmu over the toolchanger now that i got hooked to it. And maybe im the minority but it wasnt so much about filaments savings as about printing time. The first time i sliced a model that was print on my mk3 for multicolor with mmu i was kinda shocked for the time overhead. And the addition that came with even just a fail change with cryptic to no reason. That why i said im not sure that people are printing so much multicolor. Coasters and signs are not so much hassle because the color changes on top layers. The people that build functional parts will not waste time and increase a 5h to a 24h print just to add color.

All in all the true answer will come from the customer base. Thanks for you input. I believe the only solid (and valid at least in my eyes) reason that i can give a person for choosing prusa with their price/features (taking in account or not ams/mmu) is that is a level between a voron/ratrig and a high end printer. It has an "alive" upgradability path and tinkering capabilities but in its original form is a solid printer.

RE: Asked about opinion for bambu vs Prusa Core

When I brought my MK3S+ kit it came down to a choice between a Creality or Prusa - what really swung it for me was the Prusa reputation for just working with minimum fuss.  In that respect the choice between Bambu and Prusa is not as clear.  I think the cheaper cost for Bambu is going to be hard to argue against - especially if they are likely not to print a lot once past the initial excitement stage.

Small upgrades from say 4 to 4S are good, but the likes of 3 to 4 where the kit cost is a significant proportion of the new kit, especially where you need to print parts for many hours are less appealing (that said I did order 3 to 4S Black Friday).

If I was making the choice today - I'd probably buy Bambu, but now I'll likely buy the Core sometime next (well unless I can resist the XL)

To be honest - I'd probably point them at recent Toms hardware best 3d printer pages and similar

RE: Asked about opinion for bambu vs Prusa Core

So I have a MK4s with a MMU3 thats in its box and I need to get built.

I also have a Bambu A1 Combo with the AMS Lite. 

I like Bambu's approach. Everything is super easy and just seems to work. Their AMS unit is just as easy to load up and get printing with. But my only issue is with waste. There is a LOT of waste. I cringe with purges, it just seems to purge forever. 

Therefore I will only use my A1 for prints where I can make items face down. Coasters or name plates for instance where only the face needs colours. I print them face down for a nice finish, but it also means after the first 3 layers or so I switch to a default colour and print the remainder one colour, hence keeping wastage to a minimum - theres no need to print such items multicolour all the way through.

When it comes to actual multicolour models, then I will be using the Prusa once I have my MMU3 bolted on, simply because quality is on par (if not slightly better TBH) and the wastage will be minimal. Honestly, if you intend to print a lot of multicolour then Prusa is the best out there right now for this - if only they had a proper multicolour feeding using like the AMS to put all the spools!!

RE:

Those numbers might be what you find from your experience.. but not realistic to extrapolate to everyone.. you didn't think a camera was a worthwhile thing, but. I use my camera everyday.. I start a print and leave.. but I often want to check on a print while out to make sure it is on track. Even for overnight prints, in the middle of the night, I might  turn on my remote camera from bed to ensure the print is behaving. 

I would say that 50KG of multicolour prints is.. much.. on the large side if you are a hobbyist with only one printer. I print a lot (by my definition) and I've only gone thru 80KG in 2.5 years. Of that, only about 1/4 use multicolour parts. I generally do multicolour by layer height.. and if I tend to look for multicolour models that can be assembled with parts of single differing colours.. I would not waste miles of filament on printing items that are inefficient for filament. 

So for those people who print like me, the actual performance of the tool and its speed are of importance. I might not be printing a ton of stuff, but if I can do a print in 3 hours vs 10 hours (actual numbers from the X1C to my MK3S+) then that's really valuable. As I can finish a print before maybe going on  chore outside. 

So how the tool performs is an important consideration to home hobbyists. A compact AMS that can detect filament color and type might be a superfluous feature to some, or might make it all worthwhile when the unit switches from one empty red to another red , primed and ready to go.

Have you ever watched the guy that designs and prints everything in white filament?  He's an edge case.. but I put forward that 50kg of multicolour prints a year as a hobbyist and only making a choice based on those numbers, might also be an edge case. I could only see doing 50k of color parts if you have your own storefront.

Truly my MK3S+ would have been a huge pain if I had not installed Octoprint and a camera and had the luxury of fast gcode transfers along with a host of apps that can run under Octoprint. Prusa's newer communication system is just terrible for their new XL/MK4/Core One by relying on very slow and inexpensive hardware.. compressing GCode makes it usable but not a great release especially for a platform for the future.. .. do they all require a USB stick just to buffer gcode?  Now Bambu has its own set of problems.. warped beds, initially.. I've only used the X1C/AMS for a few months a year ago.. but they are pretty nice systems when they work.

But there are so many factors to consider for such differing uses..

RE: Asked about opinion for bambu vs Prusa Core

Two things, why I prefer Prusa over Bambulab.

 

Prusa is an european company and the printers are manufactured in europe.

 

On Prusa, I am not forced to use a cloud. AFAIK on (consumer) bambu-printers you need the cloud, so all your models are uploaded to the bambu cloud (during slicing). Correct me, if Iam wrong.

RE:

No, you don't need cloud, especially not for printing. As I know, only A1 mini requires cloud for firmware updates.

I had bad printer which was PITA for me to use it so I sold it. I don't need it much now, but I would like to get one. And options I consider are Prusa mini+ (use one at work occasionally) and BL A1 mini. Now the price for new A1 mini is 200€ (discount), while mini+ is 460€, so it is significant. And mini was released 6 years ago. Though I am also checking used ones, that is more like ~250€. But again, as someone who might spend only 2 or 3 spools in a year, it's hard to justify buying anything else than BL at this price.

But I do really hate all this cloud services for simple local tasks, mobile apps, IoT, I prefer ethernet over wifi, and I really like to buy and use products that can be repaired and maintained for a long time. So I would says there are things that Prusa does better, and I don't expect it to be the cheapest product on the market, but I would like to see a bit lower prices for older models and/or some big discounts from time to time.

RE: Asked about opinion for bambu vs Prusa Core

You aren't forced to use the cloud - you can run completely standalone if you prefer, or LAN mode only. This is how I use mine - so I just send the print via my wireless network and can keep an eye on the printer from my computer at all times. 

You do lose the remote abilities of course, and use of the app, but all stuff that hasn't bothered me, and hasn't restricted my use of the A1 at all...

You can't do any firmware updates without connecting to the cloud. Maybe this will never be an issue, but it's worth noting.  As your aware you never need to connect your Prusa for anything.

@crab Those numbers might be what you find from your experience.. but not realistic to extrapolate to everyone..

Good, now you're thinking critically and constructively.  Just as you wouldn't buy a car without thinking how you would use it, fuel it maintain it and pay the running costs it you shouldn't buy a printer without thinking about the longer term.

@tsamisa: As far as filament consumption for the multimaterials i cannot argue since i dont know

And now (don't take my word for it) you can find out.  It's something you need to take into consideration.

Actually i will. After  i bought mmu2s i always "advised" people before deciding to buy it, or pallete (the only other alternative i could think at that  time) , if they would actually mind or not the extra time,"fuzzy" reliability and waste (ok i admit i was leaning more on the time part). I never bothered with bambu ams when it came out .. cause i wouldn't touch another single extruder multi-color solution that exponentially skyrockets print time so i never touched this aspect between the two of them. And lets be honest here. Before mmu3 (which i dont have but all reviews are positive) mmu2s was not a match for ams, waste or not waste. AMS was working. MMU2s had a lot of complains in this forum. Im  not a hopeless tinkerer but i do design, program and generally make functional things and i would consider mmu2 to be stuck to beta version. With mmu3 is a different game and i'll tell them to take waste in to account. I'm not 100% behind the numbers you write (different usage) but i'll use the point you are trying to make, even if this is actually concerns only the aspect of multicolor and no the 3d printer as such. Of course my final advice will be TOOLCHANGER. No comparison. Waste or no waste.

RE: Asked about opinion for bambu vs Prusa Core

A lot of great points made and as it has been stated, it depends on who is buying and what you plan to do with it. For an absolute novice to 3D printing, who is sticking their toe in the water to see if they even like it, cost is a big consideration. I typically would not recommend a near $1,000 printer to someone with limited resources who is not sure 3D printing is for them. BL A1 mini with AMS might be a good recommendation. 

However, my friend who is an engineer and loves to build, mod, and tinker. I would probably recommend the Prusa MK4S kit and MMU3. He has more financial means and the desire and aptitude to learn how a 3D printer works. He is not just interested in it as a printing tool.

We would likely have a similar discussion if the topic was whether to recommend a Tesla vs another EV brand. We could spend all day picking each one apart based on range, cost, handling, space, comfort.... Sometimes it comes down to what you like, even though there are choices that are faster, cheaper, or have more features.

I did buy an MMU2 and it worked well for multicolour - but I bought it for multimaterial ... OK, I learned a lot but once I discovered the Manual MMU method I removed it and cannablised the useful components.  Now, today, I have the XL printing two colours of PLA and one of TPU to make a print-in-place hinge;  the MMU could never manage that.

I'm not 100% behind the numbers you write (different usage)

Likewise, they were just the examples at hand for three users sharing a dodgy lunch and testing the sales hype. 

Cheerio,

RE: Asked about opinion for bambu vs Prusa Core

Thank you, @tsamisa for collecting almost all of my thoughts for me 🙂

I'm probably going to get a Prusa Core -- maybe even assembled -- partly because I have so many print sheets and nozzles (first Prusa was a Mk 2S upgraded to 2.5, then Mk 3 upgraded to 3S, now 4 waiting for me to have time for the 4S upgrade). I think Prusa's enclosure for the Core is very well designed -- I especially like the spool holders tucked into the sides. I have my printer on a desk with a wall behind it. Bambu's spool hanging off the back approach would be incredibly inconvenient for me (I have no interest in multicolor printing).

Bambu's use of LIDAR and AI to detect first layer issues and spaghetti failures is clever, but given how reliable both machines are, I'm not sure it adds that much value. And speaking of value, hey Bambu: if those $11 anti-vibration feet really are "The must-have upgrade part" just pack them in the box with your $1000+ printer already. Sheesh.

My printers also back on to a wall - so not only having spools behind it will inconvenience me, having to deal with the 'poop' that's ejected from the back of the printer would be a pain also. I'd need to print a slide that brings it down to the side etc. Hence I prefer my A1 which ejects the purged filament off of the side. 

As for the Prusa, I'm building my MMU3 for my MK4s right now, so looking at how I will mount the 5 spools of filament - most likely on a shelf above the printer - but at least there's no purged filament being flung about to deal with!
