Is it really? I've looked at the Bambu Lab printer and while on paper it looks nice I would be very hesitant to buy it, their "advanced" features not that convincing: - IMO multi material printing has always been a buggy gimmick (mostly multi material setups are very prone to failure). - Them advertising that the printer can print "advanced" materials like PC is a gimmick too, the main issue with FDM printers is laye…

> - IMO multi material printing has always been a buggy gimmick (mostly multi material setups are very prone to failure). Agreed, with the asterisk that this applies more to multi-feeders (Prusa's MMU, Bambu's AMS) rather than IDEX. Which is where Prusa's going with the XL, and I'm excited about it. > - Them advertising that the printer can print "advanced" materials like PC is a gimmick too, the main issue with FDM…

> PC printing is really handy for intrinsically bespoke things like tools in the wood shop.

Can you name some examples? As a hobbyist woodworker I've used my 3D printer to print router templates where PLA was fine enough for the task.

> Aside from cost of development and manufacture, I don't understand developing new bedslingers

Another reason is that bedslingers are good enough for most users. If you dont try to print 30cm high columns with 300mm/s a simple bedslinger will do. I've printed my best minis with a slightly modded Ender 3 and I have a pretty high end CoreXY printer. I could tune the CoreXY one too to be on par with quality but for such stuff bedslinger vs CoreXY doesnt matter

For that price tag I would add a couple of hundred dollars and go with the SnapMaker 2. The nice thing is, that it is capable to do also laser engravings and simple CNC milling. Only made good experience so far. https://eu.snapmaker.com/de

Everything I've read about the snapmaker suggests it's a "jack of all trades" and not really great at anything.

I've been always a huge fan of Prusa and always wanted one (just haven't for various reasons, not so much financial related). But this feels too little too late. Bambulabs is absolutely eating the market and I would be sweating if I were Prusa Research. It sucks since Bambulabs is using their slicer and a lot of Prusa's technology as a foundation. But most of the people I know have decided to skip waiting for the XL…

>It sucks since Bambulabs is using their slicer and a lot of Prusa's technology as a foundation. Prusa's slicer is just a fork of Slic3r so I'd say that's fair play. Prusa just aggressively brands opensource stuff.

It's not just a fork with rebranding though. The development done on top of slic3r are genuinely huge. And you can use this fork for any printer too (and plenty of people do).

It's nice to pay for actually open development.

From outsider perspective (fdm) 3d printers plateaued relatively quickly; while the speed improvement is undoubtedly nice for heavy users, even at 3x speed I don't know if it is really transformative. Meanwhile the print quality hasn't changed really that much afaik? Of course being more reliable and less fiddly are certainly good improvements but I don't see them being transformative or making 3d printing conquer ne…

The speed is far more important than immediately obvious. To be able to iterate on the scale of minutes and hours and not hours and days is a game-changer. Imagine how productive a programmer would be if their compiler used to take 1.5 hours every time they saved something and it now took 10 minutes.

This is so true. My iteration time for printed parts has gone down from 4 hours to 1 hour with the faster speeds. At first, I couldn’t iterate fast enough to keep up. I can pump out a few revisions in a day or play with several concepts in little time. It’s a great time to be get into 3d printing.

Personally, I think buying any Chinese product when an alternative exists has become unconscionable. China's current support of Russia is an obvious issue, as well as their threats towards Taiwan and their destruction of democracy in Hong Kong. Problems with IP infringement abound, and in this case it's particularly disappointing as Prusa is committed to open source. I hope Prusa continue to innovate, but I also hope…

good luck avoiding the components, materials, and packaging everyone uses that are made in china. including the stuff made in india, malaysia, thailand, japan, singapore, indonesia, germany, usa, canada, and mexico. i say if you want to fight for democracy, pick up a rifle and join the marines, or go work for lockheed or raytheon. our military could always use more smart people.

That's ridiculous..

There's a huge difference between supporting a product fully developed, designed and marketed from China, with Chinese companies taking all of the margins -- versus a product with various sub-components with razor thin margins supplied from China.

China is desperate to climb up from low-value, low-margin contract manufacturing to higher end work. Their rising wage levels and demographic shift demands it.

The rest of the world needs to put its foot down and say "No, you can keep taking low end contracts if you want, but if you want to move up the chain you have to grow up and act like a mature industrialized country. If you're not going to let foreign companies operate and compete on fair terms in your country, don't expect us to let your companies compete freely in our countries."

Manufacturing is already slowly moving out of China due to rising labor costs and automation. If we stop buying stuff fully owned, designed and marketed from China, the pressure will keep increasing for China to get its act together.

I mean, otherwise we might as well giving up on designing and marketing anything in the west. China will have a crazy advantage if they get to play by completely different and unfair rules, ignoring our IP laws, getting subsidized shipping on everything (since they're a "developing" country), getting to ignore quality control because returns are hopeless, getting to flood Amazon with low-quality products with fake reviews, while working from the place where all this stuff is manufactured anyway.

It says high speed printing will come in a firmware update... Have they released remote printing support for the Prusa mini yet?

The update with wifi support for Prusa mini was released ~3-4 months ago. Or are you referring to something else?

The Prusa mini has an ethernet port, so people assumed that you could hook it up to your LAN and print over the network.

As far as I can tell, that doesn't work yet, and the Prusa website [1] says:

> Full control of your printer will be added in future releases

Edit: It looks like remote printing was released in a Firmware update in Nov 2022 [2] and the documentation website wasn't updated yet.

They also just published a blog post[0] discussing the hardware equivalent of SSPL if I get it correctly. 0: https://blog.prusa3d.com/the-state-of-open-source-in-3d-prin...

Several of those suggestions would violate the OSHW definition, a definition that was endorsed by Prusa himself: https://freedomdefined.org/OSHW

Thinking about it a bit more, I think Prusa is simply struggling to maintain a foot hold in the industry and remain open source. All the complaints are about the printers. But Prusa does more than just printers.

Prusa forked Slic3r into PrusaSlicer and continuously deliver great improvements and still keep it open source. If you go to the PrusaSlicer page, their github link is right there. And they support Windows, Linux and MacOS. They also attribute Alessandro on the website and the launch screen. The Prusa github also seems to have all their projects and software.

Bambu Labs forks PrusaSlicer and the github link is no where on their site and they only support Windows and MacOS On a piece of software that already had Linux support and the only acknowledge it's a fork on the github. Fortunately the github is still the 2nd link in google. But they aren't really committed to releasing their work if they won't even link to it. And their github has like 2 projects.

Prusa created printables.com to clean up the mess that is thingiverse. Creality created Creality Cloud and then just steals your models even after Naomi Wu advised them not to do that. Prusa runs competitions, has prizes.

Prusa seems to want to keep things open source, try and create a community. But like most open hardware, it's expensive relative to the competition.

As an Apple user, I completely understand the need to not mess about. But I also like to use opensource where possible. Especially for things I want to tinker with. So it's really surprising to me that what seems to be the majority of the hobbyist 3D printer community, a community that tinkers by definition, wants more closed, less repairable hardware. And more propriety software. They just want the cheapest appliance they can get for the money. I think this is what broke my brain. We started open, and could remain that way. But we'd rather not.

It's hard to fight against the might of cheap Chinese manufacturing. I hope Prusa works out a good strategy to survive before we end up in a situation where all the 3D printers requires Windows or MacOS and a login to some cloud service that I don't want.

maybe you should try to stop buying cheap crap in general instead of getting angry at shady internet marketers on the other side of the planet.

you're not going to stop china's economic rise without military intervention. the world is a big place with lots of markets. join the military and be on the front lines of the coming cold war where you can do some real good.

>But i recently got a resin printer and that thing lives in the bathroom now beside the washing machine. It has build in ventilation through a coal filter but the stench is just awful. It's also worth noting that the smell varies considerably between different kinds of resin. having a dedicated space is optimal, but with the right materials it's farily manageable, especially if you're not planning to run it 24/7.

I use water washable resin because it is super convenient. It is supposedly not that bad smell wise. But I find it still unbearable.

The printer is used to print the occasional tabletop model and stuff if it where in use all day I would try to get a better solution

> Just spend some time on the Bambu Labs subreddit and you will see a lot of frustrated owners. I have had mine (w/ four total AMS units) for two months now and have over 500hrs of printing so far w/ minimal failed prints. I often print in sport and/or ludicrous too. I own eight other 3D printers of various major brands (including Prusa) and it’s by far and away the best I’ve ever owned. Easily comparable to printers…

Just curious, while I’ve ordered various 3D printed parts, I’ve not bought a 3D printer. What do you use 9 3D printers for?

> What do you use 9 3D printers for?

I’m probably going to start pairing that back, in fairness, and sell off 3 or 4 Creality printers in the near future. The reason they were useful is they were decently reliable and “good enough” and the multiples of the same were to run jobs in parallel. With the massive speed up from the Bambu Lab X1 and the better likelihood of a consistent print experience, I don’t need to have as many parallel prototyping runs. The other remaining printers have characteristics that make them worth keeping (huge print beds, different tech as in SLA resin, or simply sentimental value).
