Indeed. I always thought they deferred the launch of any new model after X1C in order to take the true "just works" crown back (with the hopes of it would be something like Intel/AMD feuds where the monopoly had finally came to an end and customers can finally see some real competition). But apparently it is just a classic Prusa printer with better parts but still a very very high price to usability ratio (compared t…

It's a proprietary versus open source argument. You can build a mk4 clone for much less than the price of a Prusa-branded one, as everything is open source. The higher price tag is like a donation to open source. Prusa also makes the open source XL if you want an CoreXY model, or you could go with a Voron which is also open source.

Thats an odd analogy.

Prusa loves open source and maker mentality. Just look at PrusaSlicer and Printables.

I've owned an MK3 since 2018, since then some defects have started to appear (the LCD has a contrast blob at the center, and I cracked the X-axis stepper bracket), but nothing that prevents the printer doing its occasional job. I print mostly functional parts (home repairs & improvement, prototypes), and while I could have printed a fix for the broken part, the prospect of taking the whole thing apart (as well as for…

It would be wise to print a new part while you can, just in case the cracked part fails completely at some point.

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…

My FDM printer is not stinky enough to cause a big problem (might be still unhealthy though). 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. In a pinch Bathrooms are not the worst place for printers because they have ventilation and are not in use most of the day. Just don't store y…

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.

God damn it - I just bought a MK3...

The announcement article says people who bought a Mk3S within the last month will receive a voucher for $150 or $200 which could be put towards the upgrade kit (or, I assume, filament etc).

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

There are so many variables which one might want to tweak depending on their specific use case that it seems a bit difficult to boil it down to one-click.

Especially with slicers still introducing all sorts of improvements which might need tuning of their own to adapt to older designs.

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…

I have two MK3S and I have to say I love them. They're simple, they work well, and I can repair basically any part on it using their documentation. The new model adds mostly refinements for people who want to do production printing.

I have a Mk3S and a Bambu X1C. The Bambu is much, much better. The Mk4 covers most of the distance, but at a price point matching the X1C, and it's only most . Speeding it up is nice, but... pressure advance depends on detailed characteristics of the filament, such as viscosity, which varies from brand to brand and color to color . The X1 has a lidar, which from experience actually does work as advertised. The Mk4 ha…

As far as I've seend the X1s lidar is mostly useless, it's doing fine-calibration at most based on the current filament profile and seems to be inconsistent.

That's not to say that the X1 itself is - just that lidar is imho a gimick.

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 layer adhesion and no matter what material you are using its going to suck compared to injection molding.

- bashing bed slingers is wrong too, they have their advantages compared to CoreXY setups (mostly simpler mechanics)

IMO FDM printers have 2 main issues:

1. Unreliable due to lots of moving parts. A solid design with quality components mostly mitigates this.

2. Layer adhesion sucks limiting possible applications. Some very innovative non-planar printing could be a solution but it does not exist yet. Or could be solved by printing metal, but these devices are far from home use.

Resin printers solve both issues, but bring their own (mostly that resins are very toxic stuff that you dont want in your home.)

So no, this printer is in no way revolutionary (neither is the Prusa). Until both of these issues are solved home 3D printers will be mostly used to print benchies and accessories for tabletop games.
