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.

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…

Box around the printer with a vent/fan blowing outside. It'll be negative pressure in the box, so everything should just vent out. Even if you can just crack a window and get the airflow going out the window... you can push a flexible tube far out onto your balcony...

Would someone explain what is notable about this? I'm not familiar enough with the 3D printer space to know what new features and capabilities are developing.

Its more just a brand thing, Prusa was one of the early big names in (hobbyist) 3d printing scene. I don't think this printer coming from any other brand would have reached the front page

Prusa does have an official enclosure but I'm not sure of its MK4 compatibility. https://www.prusa3d.com/product/original-prusa-enclosure-3/

You may be able to get by with a regular air filtration system. Not sure where you are, but I have a Rabbit Air[0] that is very good at removing smells has multi-layer filtration.

Also, buying good quality filament is important. You want stuff that isn't made in China.

It’s the one FDM 3D printer worth buying that is being cloned and copied with so-so results by Chinese companies. Unlike Ender etc., Prusa is the true “just works” FDM printer

I do recommend Prusa to new 3D printing hobbyists because there are a lot of quality of initial experience features on them.

That acknowledged, my (lightly modded) Ender3s, a Flashforge Creator clone, and an SKTank kit-built printer all also “just work” and, other than capability differences, use the same machine settings in slicer/same gcode thanks to Klipper macros (to the point that I’ll often start a print on them in the basement without ever going down there and checking that the first layer looks okay). I’d say I’m well above 97% for prints work without any fuss.

Nice - but it's been over a year and a half since preorders for the Prusa XL began and it still has not shipped!!!

It is clear now that people who preordered the Prusa XL had availability sacrificed for the MK4. It just sucks if you've been waiting more than 18 months for that, only for the MK4 to get day-one availability before your long-awaited preorder.

Creality has this $60 enclosure that seems to do the job. I learned that the entire voron project is against separate heaters, they recommend to leave the heated bed on for an hour instead.

It is compatible:

> MK4 is fully compatible with the Original Prusa Enclosure.
