Hi @Maker5162 thanks for the clarification. I think price vs quality and reliability becomes a very difficult discussion when dealing with technology (or many other things for that matter!). It’d be lovely to be able to definitively say that a “thing” that costs twice as much as another “thing” does its job twice as well, but we all know that’s not usually the case. If we’re right down the bottom of the market, the lower priced thing could be virtually useless while the higher priced one does an OK job; at the upper end the differences between the two could be hard to spot (and the higher priced thing is almost certainly overpriced). And, of course, there’s every stage inbetween.

The Prusa Mk2 and the Makerbot M2 are, on the face of it, very similar machines. Virtually the same build area, both open source, both the same physical design, etc. The M2 can go down to 25 microns rather than 50 for the i3, but really I rarely print below 100 microns anyway so it’s debatable how important that is for a new user. So, someone looking to buy their first machine is left asking, what am I getting for my extra $1000? Your argument (and I’m not disagreeing with it) is that the extra cost is in higher quality components, greater reliability and so on, but that’s really only relevant if the i3 Mk2 has demonstrably poorer quality issues in terms of reliability, etc. What’s important to any user is whether they’ll actually be affected by any such issues. If the M2 will print 24x7 for 10 years and the i3 only 6, I’d argue that’s irrelevant to me because I can be pretty sure I won’t be using either in 6 years time. If the Prusa will break down in a year, that’s more of an issue, but it seems unlikely and if it breaks down, I’ve got $1000 in my pocket I can use to repair/upgrade it and, perhaps more importantly, by then there will be other machines on the market and that $1000 could buy something even better than the M2, who knows?

I think the M2 is a fine machine, I have absolutely no criticism of it, but this thread was started by @marczem who has said he’s a new user, looking for a hobbyist/enthusiast machine and that being the case I’d argue the Prusa is a better choice because it’ll do everything a hobbyist will need and it leaves $1000 in their pocket for filament, the multi-colour upgrade, spare nozzles, etc., or to reduce their wastage if they discover 3D printing isn’t for them. If the original poster was an experienced printer with specific needs, the M2 may well be the better choice, but that’s not the case here and we should consider the person as well as the machine.

If neither machine has a major issue over a similar time frame then your first paragraph is really irrelevant. Which it really is anyway. You are comparing two products built by different methods and different parts with a considerable cost difference that can do the same basic function. Really an apples to oranges comparison. There is no dispute that the M2 is a good machine but saying the MK2 is not because it is not built with the same parts is disingenuous.

In the second paragraph - again you make a comparison that is irrelevant. You compare “old-different” models of the i3 but not the MK2 of discussion to the M2 so your claims of reliability etc are again baseless.

“One of their new features is literally a software program that enables you to print on a mis-assembled machine — this is not something that one would even want if quality and performance are their top priorities.”

Again, you over dramatize a feature with “mis-assembled machine”. An advanced feature of the firmware and leveling system is its ability to adjust for very small alignment issues. To say that you can incorrectly put the machine together wrong but a magical “software” will make it all better is misleading.

The purpose of this feature is to let the builder and user know there is an issue and have a means to diagnose and correct it. No machine stays perfectly aligned and level as it is used. Some do better than others but we are not talking high end CNC machines here.

You must then feel auto leveling systems are also only to compensate for problems on inferior machines or for users who don’t know what they are doing and thus have no business on a “quality” machine.

With all respect, all you have done is give this guy a lot of miss information and innuendo. If you like and have experience with the M2 more power to you and provide him with useful pros and cons of the machine. It does seem to be a well made albeit expensive, well received machine.

If you don’t have direct experience with the MK2 then negative comments are hearsay and not useful.

Personal experience with older models can be relevant to address issues of past so a potential user can research to see if it is still there.

I tried to give the person my personal experience and opinion of the MK2 and made it a point to say I have no experience with the M2 thus couldn’t comment.

Ok, I think we have all said enough! Let’s move toward helping a new user make an informed decision.

Thanks for a spirited debate.

Yeah that is what I was discussing sorry if there was confusion I was abbreviating.

This guy has been on the attack on anyone who mentions anything other than worship for the M2.

My opinion for what it is not worth - if you like the M2 and have had a good experience with it then great but no reason to attack everyone with a differing opinion or experience.

He won’t like this then! Aside from “Make” another very respected site had this ranking of their top 20:

I spent a lot of time looking at these two printers, ultimately I went with the mk2. The most likely use will be 3d gaming scenery. The review on fatdragongames.com 2 ultimately sold me. I like when products over deliver… mk2 claims .05 resolution, but reports of printing with great success .025, and he isn’t the only one, appeals to the overclocker in me. Dreams of warhammer quality miniature armies, not really but the possibility of, are nice if not the current reality. I have waited years to get a 3d printer, till the quality, stability, and value/$ ratio got to the present levels. I am hopeful that in two years I will be buying a new one at even greater resolution, speed, volume , and ability than the current m2 even suggests at mk2 pricing or lower.

In the mean time I will build scenery for my games, toys for my kids, and start learning 3d. 20 years ago I’d have bought the kit version, at 50 now though, I’d rather concentrate on learning the use for now… time enough to learn the build if I discover a need/ability to upgrade components going forward. If I was looking at this from a buisness stand point, the ability to have two running in case one went down would be appealing… dual extruders would be nice for dissolvable supports but, that is a consideration for the future. My hope now is that the mk2 system will allow implementation of multiple spools of same material on same extruded, so that as one roll ends the next can provide uninterupted material supply. Might require sensor upgrades on the feeder, but problem seems solvable in my naïveté . It might not be a huge issue, but It would suck to have to have 9 or 16 pieces of scenery/ figures aborted because I ran out of material 80% of the Way through a print.

I have played the tech game on computers for almost 4 decades, Looking for the sweet spot far enough back from the bleeding edge to not waste too much money, but far enough forward to get the functionality I need to be happy. For me at least, I am going with the mk2. I understand that the m2, might be better. Like the top end $1000+ CPU is beter than a $300 CPU when I build a computer. But the demonstrable benefit to my life at this time, in a field I expect to continue developing relatively fast, is minimal.

I did appreciate the conversation I found here. For those like me who are starting out, this is where I landed. If the noise level is a problem, that will mearly determine which room this printer ends up in. Of course with three kids under 9, printer noise is likely the least of my problems there.
