Down the road, you might want an enclosure. You really only need one for printing things like TPU and the like, that need to stay hot throughout the printing process.
I host a user's group at our local public library for their 3D printer. I've helped quite a few people getting started and keeping running. IMO, the first couple of criteria are dependent on YOU! More than half the people getting their first one end up with it on the shelf. Here are the main stumbling blocks I have observed. I'm not implying these apply to you at all... It's just what I've observed by many first time purchasers.
Assuming you're good to go on those two, here are some lesser items (Just my opinion)
- Many people I've worked with are artists wanting to just print art. They have no ability or interest about learning CAD or similar software to make their visions. Most aren't even computer literate. They end up merely printing Thingiverse.com models that others have built. They get bored and frustrated that they're not building what's in their minds and aren't willing to put in the huge learning curve to build their own models. Assuming you are on this forum and are primarily interested in printing planes or parts for planes, there are many fine airplane models available. Some free, some for a nominal fee. You may already be a CAD expert and have a vision and the ability. I don't want to sound immodest, but I would consider my CAD skills toward the expert side. Trying to take Internet images of some airplane you like and making a 3D model of it... is a HUGE project. In this project https://forum.flitetest.com/index.php?threads/p-38-lightening-epic.71024/ I probably already have 30 hours in it and I'm starting from very nice, high-resolution blue print type images. Just modeling the outside geometry will probably take several more hundred hours. Then there is a huge learning curve to get the knowledge of how 3D printers work, their strengths and liabilities. You'll need to cut your models into manageable pieces to fit on your printer in a way that is both strong and doesn't require "supports". Designing the internal structure is almost as daunting at the exterior geometry.
- Then... they were expecting it to be bullet proof like an ink-jet printer. You must be mechanically inclined! You must be able to adjust the printer, tune the printer, take apart the printer and successfully put it back together. You must have the logic to be able to diagnose problems with the printer, typically on your own, but with help from the Internet can often overcome most hurdles. Many people, I've seen get their first clogged extruder and that's the last print they'll do. I know of no shops or Internet places that will fix your printer like the "Geek Squad" and if they did, it'd cost as much as the printer.
That being said, I bought the kit version of the Prusa i3 Mk3. Building the printer was well worth the experience when it comes to tuning it, fixing it... etc. I have modified it and built a heated box for it. It is a work horse... Prusa uses their printers to make the parts for the printers they sell. Mine has...
- I wouldn't go with anything over the nominal size of 220mm x 220mm x 220mm. Meaning going to the 300, 400, 500+ sizes. Most are in this ~200 range. No matter how big you go with the printer, you'll always want to print something bigger. Might as well get used to printing in pieces and fusing/gluing them together.

- Speed... Get used to 8, 20+ hour prints. If your pocket money is measured in thousands... then by all means get the best. But you'll spend 10x more to get a high speed printer using high-end nozzles, rigid frames and typically will be using CoreXY type designs. You might get on-average twice the speed... so still 4, 10+ hour prints. I just CAD up a part get it on the printer and start CAD'ing the next part. Even when I printed a pre-made plane off the Internet, it took about 24 hours total. https://forum.flitetest.com/index.php?threads/cub-training-j-3.71041/ I spent maybe 1 hour changing out pieces while it printed... during dinner, while sleeping, while doing other things. You'll just get over needing speed. Save 10X.

That being said, I only recommend the Ender 3 series printers for those starting out as a cheap, but good quality printer that will give great service for less than $200. There is a huge closet industry of available help on the printer and parts to mod the thing as you learn what is important to you.
Good luck.
So I have this friend...... she needs to mass produce a tschotsky
I wouldn't say 220x220x220 is the max size you need to go; that's more of the average build size. But I agree with most of what you're saying there.
Only thing I KINDA disagree with is that the Ender series is the best. It's the best option for sub $250.
Well you took something out of context... I said, I would not suggest spending extra just to get the bigger models starting out. The price nearly doubles just to go to 300mm cubed. And 2... I never said the Ender 3 was best. I said it was a good/solid/cheap printer. If you know of a better sub-$200 printer, I'd be interested in hearing it. I help a lot of money strapped parents trying to support their home-schooled children and a $400 printer is not in the cards for them. Nothing from Monoprice is better. I have IIIP Delta and use it as a paper weight. I know one that had the Monoprice Mini and gave it away. The volume size on those are real handicaps unless all you want to make are chess pieces and D&D characters. None of the people that I helped with getting an Ender 3, had any trouble, but I was there to mentor them before and as needed. Sure... if you're well healed and starting out, you can get one of the $2000+ models that are all nice and pretty plastic sealed chambers with carbon filters and blah, blah, blah. Our library has one of those... and frankly all the bells and whistles get in the way when something goes wrong. And they have had more trouble with it than any of the Ender 3 people.
About the only feature that a base model Ender 3 doesn't have that I would recommend looking for is the auto bed leveling. It is worth some extra. I haven't looked at their models in some time, but I checked Amazon... before Black Friday, an Ender 3 is $189 and that's not the cheapest it can be had.
The MP10 is mostly assembled, is a 300x300 print bed
auto bed leveling, heated beds, all metal hotends
I've not kept up with them as I'm happy with what I have and no one lately has asked for a printer. I will take a look at the MP10.
I would like to clarify a few things and ask your opinion on...
I acknowledge that they cut corners.
- Although I like the pseudo bed leveling on my Prusa, my son says its easy enough to do with the big knurled knobs on the Ender 3 and he rarely has to do it anyway.
- All Ender 3 that I know of have heated beds. The one I bought my son 4 years ago had one... the $179 one on Amazon: https://www.amazon.com/dp/B07D218NX3/?tag=lstir-20 has one.
- All metal hot-end. I can't find anyone that can tell me what the advantage of an all metal hot end. My Prusa came with a non-all-metal hot-end and they recommend keeping it below 260C. I don't use PLA and I run the Prusa at 255 for ABS, Nylon and Polycarbonate. A little colder for TPU+. Have never had trouble and still on the same tube. I've changed the nozzle quite a bit from hardened steel for Carbon filled filament and use different size nozzles, but have never run into a need for an all-metal-hotend. When I first started years ago, I seem to recall reading that all-metal-hotends tended to clog easier, but I don't recall the source. Out of the 80 kilometers of filament, I have had the hot-end clog only once and that was using PETG which I'll never use again. Never had it clog with ABS, Nylon or even carbon fiber filled Nylon or Polycarbonate.
