I want buy an UM2 DIY KIT in the Aliexpress

Posted · I want buy an UM2 DIY KIT in the Aliexpress

Remember you get what you pay for !

There are different opinions about China stuff, some say good some say pretty bad, but I wouldn't want to have a fire hazard in my house :)

and you might not be able to print any decent prints (or after a while) without replacing shoddy materials with better and more expensive ones,

why not buy a UM1+ ?

I am a freshman. UM2 must be better than UM1+, So I want it. China stuff have a lot of uncertainty, but the UM2 DIY KIT is only I found , It is also really very cheap .

First of all you're a man without 3d printing experience. Why not trust the experienced people here?

Or do you just wanted a positive statement?

Ok here it is: Go ahead and buy it ;)

I was going to say the same :)

I wouldn't trust a UM2 clone from aliexpress. Maybe it's a good "copy" but maybe it's a horrible one. Anyway, i don't think people on this forum have UM2 clones so probably no one here can tell you what it's worth.

Aliexpress is a bit like russian roulette, sometimes it doesn't blow in your face ;)

Exactly it's a gamble. If you already knew what works and what doesn't you could make a clone from parts of different places with great sucess.

Key parts of the printer:

-The board, you don't want the house on fire.

- Power supply, same reason.

- High quality smooth rods/shats. Quality disappear without good head movement.

- Perfect, not just good, nozzle. Same as above.

Head, ptfe, bowden, extruder. Bad quality means horrible and hard (imposible sometimes with bad quality) extrusion problems.

- Perfectly flat table. Quality issues.

- Great motors. Bad quality = bad prints, overheat, more problems.

- Perfect bearings. Bad bearings break fast overtime = more time and money expenses.

And a large etc

Hi! I am from Taiwan. And I am happened to be a user of that UM2 Clone, from same seller.

I can't promise you anything, and I can't say it is good or poor, because I don't have an Original UM2.

But I can share some of my prints.

Ofc an Ultimaker kit can have problems, but that's the great think about buying something with warranty. I had 2 bad shafts, they replaced it. A plastic part of the feeder broke, they replaced. The 1 year warranty and support it's quite good to have.

The way I see it, there are two issues here:

1) Are you going to get a decent printer?

2) Just how ethical is it, since these guys are using all the research Ultimaker did to build their clone without passing anything back to Ultimaker

On the first note, it's impossible to tell, because even if you get 100 good prints off it, it might deteriorate irreparably from that point forward, for a number of reasons. Or you might just get lucky and it's as good as the UM2.

On the second point, even the the Ultimakers are open source, it does not necessarily follow that commercialising their source without their permission is in the spirit of open source. So, difficult choice there.

Ultimately, it's a case of greed versus being sensible. If you are greedy, take the gamble and go for the cheap product. If you are ethical and sensible, buy the UMO+ and get a known quantity, and support the company that brought this research to you.

Yeah, thanks, you are right.warranty and support is the most important. I will consult that.

I just contact 3D printer not long time, I have been looking at UM 3D printers, UM2 is my favorite. But my budget is limited, So I am more concerned about that. At the same time I also like DIY KIT, I really enjoy the process of assembly that gave me a sense of accomplishment. Thanks for reply!

Everybody buying this or another UM2 Kit should be aware that such a kit is very likely not approved by Ultimaker. Official UM2 machines are only sold assembled. Ultimaker published the hardware details under a non-commercial license. I somehow doubt that a manufacturer from China has actually asked for a commercial license at Ultimaker HQ. If I'm wrong, I kindly ask someone from Ultimaker, e.g. @SandervG, to correct me.

To make a long story short: Don't expect any help or support from Ultimaker if something doesn't work as it should as those kits are most likely not really legal. Personally, I would also not feel an urge to help people here on the official forum who bought a wannabe-kit.

Ultimaker is aware that not everybody has the budget for an UM2. That's one reason why the UMO+ is still produced and sold as kit, as @Neotko proposed.

Nope, you are right. It is an unauthorized clone.

Just noticed that it's a non-commercial license. I am sorry for being a user of that clone.

To counter all the nay-sayers a bit (though not entirely), what you could do is to buy that kit, and use it as a base for the printer you really want...

That means replacing a lot of crap parts straight away as you assemble for the first time...

Its not uncommon for UM users, even (or perhaps especially) the more experienced ones, to replace parts of their printers... Though its more of a UM1 thing, the UM2 users are slowly following as the machine gets older...

So in the end "all original ultimaker" is not necessarily all that good, or what you really want.

However!

I can assure you that very few people (read: none) will be taking their UM apart to replace its parts with cheap Chinese ones (at least not the critical ones), and so, your end product (china kit + quality replacement parts) is probably going to be of quite a similar price as an Original UM.

On top of this, modifying a 3d printer, knowing what to get, installing it correctly etc., requires experience more than anything...Experience that you, as a first time user, do not have.

Another kit from them?

If so, why you ask on the forum if you already had one?

Their own research?

Please don't make me laugh...

This smells like a publicity stunt

I wouldn't really trust this clone, and for that price, I'd totally prefer to spend a little bit more and get an UMO+. I even prefer it over the UM2.

And I'm deeply sorry for Ultimaker, I understand your feelings about this. I share all my designs with a non-commercial license, but there's a lot of people that won't care about it, or they will just think "If I can download it for free, I can do whatever I want with it". :(

I'm trying hard not to point out the obvious...the Chinese steal/grab/take any intellectual property they can, legal or not, and make cheap copies. To come to this community looking to get something "cheap" then hoping for support is dishonest, at best.

Almost all components are made in China nowadays. That's not the issue.
