I’ve been waiting to finish up with some major life stuff before diving into the world of 3D printers. Now that is finally behind me, and I am currently trying to find out which printer I want so that I can place an order.

So far I’ve set my eyes on the new Prusa CORE One. It ticks a lot of the boxes that I think I am after, including:

  • As open as I can get (before going into that Voron-stuff, which I think I’m not ready for). I don’t want to be bogged down with having to run proprietary slicers through Wine and things like that. I am not sure how big of an issue that is with e.g. Bambu or Creality (if at all), but I’ve seen enough rug-pulls and enshittification processes that I don’t really want to risk that. I want to be sure that I can use FOSS tools such as Blender and FreeCAD for design, and similarly open slicers, and the whole workflow will work just fine.
  • As future-proof as I can possibly hope for. I think the upgrade path from the MK4 to CORE One shows that they are serious about sustainability and longevity of their devices, and as far as I can tell, I should have no troubles sourcing replacement parts. I also want to support companies with this philosophy.
  • Has a decent print volume (I know there are bigger, maybe I will be constrained by this at some point?)
  • Enclosed - a major reason I did not want the MK4S was that it was not enclosed (but maybe you can get an enclosure?). It will be placed in my study where I spend most of my computer time (which often times is a lot, so I imagine I will be in the room while it is printing). I imagine, with the additional filter, that it will be better with an enclosure. Also, it will be easier to keep good temperature control during prints, as it can get cold here during winter.
  • Locally produced (I’m EU based).

I understand that other manufacturers provide more “bang for the buck” and that I in that sense will be overpaying feature-wise. I am fine with that given my emphasis on the above criteria.

However, I am a complete newbie to 3D-printing. I am sure there are some limitations I have not thought about, and I was wondering if there are any major things I have not thought about that would actually affect me negatively and should make me reconsider this model?

    There are a fair number of methods to join pieces into larger assemblies.

    Some people have used a 3D pen to “weld” an assembly. But from my observation, it’s not particularly strong. Super glues are popular for PLA. It bonds and holds well to PLA. PETG is better glued with epoxies vs super glues. But super glue will work in a pinch. Sometimes printing threaded parts is acceptable. But issues with fitment and strength of threads can be a problem. Simple machine screws and nuts are good for somethings. Even self-tapping screws are popular. Heat set brass threaded inserts are cheaply and widely available. And can be set with a cheap soldering iron. Various “snap together couplers” can be designed and 3D printed.

    These are just a few ways to make assemblies with 3D printed parts. The trick is to learn how to choose what is the best for any particular model and that’s on you.

    Making a model hold water can be as simple as “the thicker is better” approach by adding more perimeters and top and bottom layers. Or it can involve applying various suitable paints and sealers. Again like fasteners, your use will most likely dictate the methods that you choose.

    Edit to add: From what I can see, PrusaSlicer currently offers the best tools to create cuts and locators right in the slicer. With perhaps Cura a close second, (but I haven’t use Cura in couple of years now).
