I don’t know why this is being down voted. Prusa are trying to make an open source hardware company work and I guess this is what it looks like. There is so much noise on HN about repairability. Well here is some open hardware And it’s ”the Chinese printers have so much more features!”

My experience with repairability on Prusa is pretty awful, lots of $1 parts that need to be airmailed from Czechia for $50. At least the Chinese stuff is easily available.

If you're in the US, printed solid is basically prusa's US arm now and carry a majority of their parts.

So I would really like to get into 3D printing, but I struggle with discomfort over the health implications. I live in a small rented apartment and can't easily work out space or, much more importantly, external venilation. Yes, I've looked into PLA vs. ABS, I've looked into enclosures with carbon/HEPA filters, etc., but I still don't want to have it in my living space without a vent to the outdoors. Here's the best…

How about using a printing service instead?

These look like very solid improvements over the MK3S+ (I personally have two MK3S+, and use them a lot), and I love their commitment to open hardware and for making upgrade kits available, but it's a bit disappointing to see still how far Prusa is behind truly next-gen printers like the Bambu Lab X1-Carbon.

I just canceled my X1-Carbon order. Just spend some time on the Bambu Labs subreddit and you will see a lot of frustrated owners. It is insanely loud, and it seems unreliable and buggy. I have owned a lot of printers over the years, and the only printers I, or any of my colleagues come back to are Prusa printers. They are incredibly reliable. The few times we have had issues with a part, we have been able to print a…

In my experience this is true of basically all very niche brand subreddits. People go to those subreddits to complain and/or get help. It isn't a representative sample. The people who are completely happy with their Bambu Labs machines have little incentive to spend time on a 14k user subreddit when they can go instead participant in a 1.7m user subreddit like /r/3DPrinting.

I own two MK3s+'s. They are solid machines if you are looking to print PLA and some PETG. The stock extruder is a PITA. The MK4's redesigned nozzle/heat break & 10:1 extruder are basically a Bondtech LGX + Revo & should make for a great improvement. The MMU3 seems like a marginal improvement, you still have purge towers & large buffer boxes. Hopefully the reliability out of the box has improved. I wonder if it's too…

Voron? Apparently that takes about 30 hours of build time, that's definitely not my kind of project. I want to use the printer. Bambulabs? Looks very interesting, but it's as proprietary as it gets. With Prusa it's clear what I'm getting into.

I want to upgrade from my Prusa Mini and can't justify the cost for the XL, so the Mk4 seems like a decent choice. I'm sure people building and modding their own printers and flashing firmwares might have other favorites, but that's simply not what I buy 3d printers for.

Could someone explain to me what you get from paying more for a 3D printer like this one instead of a "basic" model? I have a Ender 3 V2 with self-leveling bed (without self-leveling it's not that great) and I use it a lot, enough to justify buying a better $1k+ printer but it's not clear what I get from spending that much money on it. Is it printing speed, better materials, or something else entirely?

Reliability and speed.

An Ender 3 will produce good prints if it's well tuned, but there are a lot of quirks to the design (mostly as a result of cost-cutting) that can cause problems out of the box and will cause problems over time. Prusa printers are far from perfect, but they're trusted by a lot of print farm operators to run 24/7 with very little attention.

Modern CoreXY printers like the Bambu Lab or Voron machines are crazy fast compared to an Ender 3, without any real compromise in print quality or reliability. That isn't necessarily a big deal for hobbyists, but it's very useful when you're iterating on a design. For users who care about print speed, the issue is generally latency rather than throughput.

Has anyone figured out remote slicing? I’d love to just click print on a thingiverse page and have my printer start going.

3dprinteros has an online slicer. So, assuming you are happy with the default profile and the printer is online, you can go "Upload stl" -> "next" -> "next" -> "next" -> "print".

I've been thinking about getting a Prusa 3D printer for a long time, but now I'm leaning towards a Bambu Lab X1-Carbon Combo 3D printer. It looks really cool and seems like a more professional tool. Has anyone tried both? What would you recommend?

EDIT: I read some of the other comments in this thread and did some more research. Found some Reddit posts as well. I think I'll definitely go with the Bambu Lab printer.

I don't own either (I have an Anycubic Vyper) but the two are not at all in the same category. The Bambu totally outclasses the Prusa printers, but the price is also a lot higher.

Core xy motion system is hands down a faster setup. Also has a smaller footprint for the same printable area. And enclosed means you can do asa and Abs and nylons as a normal think.

No matter what, make sure it’s in a room with an air filter and active ventilation. Safety matters.

There’s a lot of really cool open source printer designs too, and having an abs/asa capable machine really makes a lot more cool prjects possible.

I got the x1cc and I’ve been really happy so far. My biggest problem was accidentally printing pla as asa and I still managed to make ok but weird prints

> 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…

How easy is it to repair?

Parts for it are available from the manufacturer for decent prices. I've looked at some of the repair guides and they seem decently detailed.
