    Buying a second hand UM2

    in Buying or selling your UltiMaker

    Posted

    so he is lying to you that's for sure :)

    the nozzle wouldn't block it after an hour.

    first of all, if the price is right, buy it. nothing much can go wrong with these printers.

    just look for exterior damage..

    how many printing hour does it have? below 2000 basically means it is as good as new..

    look at any exterior damage , are there cracks? are the belts ok? they should be tight. move the head around, does it move around smoothly? if not, put a little bit of sewing machine oil on it (take that with you!) and move the head again.

    then i would say a used UM2 is worth between 800 and 1000 euros depends on the hours it has ran..

    the problem he is describing is the PTFE piece.. that will clog up your prints..

    just buy the thing as cheap as possible, buy the upgrade kit for 400, it will have a new feeder, new head assembly and this will solve all those issues.. that way you have a basically almost brand new um2+ for about 1200 to 1400 euros.

    Questions about Ultimaker 3

    in UltiMaker 3D printers

    Posted

    The printer ships with 2 350g spools, but it is designed to be used with the normal 750g spools. As I understood, the main reason for the smaller spools is to keep the shipping packaging of the printer under a certain size. (But I could be wrong here)

    I'm not 100% sure if the 2.3kg rolls that you can buy at certain locations fit for a 100%. But the people that want to use those rolls will manage.

    little clarification, the 2200/2300 gram spools that you can buy don't fit. the spoolholder is moved down just a few CM as compared to the UM2(+) and the spoolholder hits the ground. the rest seemed to fit so I support a few 1 or 2 CM high supports would fix this issue..

    UM3, who's going to buy one?

    yeah, I'll get an additional one or more..

    love the printer.. sure, some things could be better, I agree witht he BondTech argument, but all the other things.. it's not necessarily better then my UM2+ printers, but it's more aligned to how I use them..

    But if I don't need the leveling then my old heater will work, right?

     

    suppose so.. you will have to take in mind that the back of the bed is now spring loaded, so it's flexible if that makes sense?

     

    The back spring-loaded? I'm assuming that's not the bedleveling spring, right?

    How is it spring loaded?

     

    O

    Do you mean that the bed itself is flexible and is held tight by the tension of springs?

    Or something else?

     

    yes, the back end of the plate can flex up and down

     

    Was that a deliberate design? Does it affect the top surface of the bed and cause it to resonate or move around?

     

    i think it is :) it doesn't impact any quality, works like a charm.

    Also, is anyone else thinking about swapping out the UMO+ aluminum build platform for a UM3 style one?

     

    Just did a quick rough measurement between the 3 and the 2 and it seems to me the 3 bed will just fit...

     

    THANK YOU. It's great to have someone who has both to measure it out :)

    I'm assuming that the heated bed has not changed. Is that correct?

     

    while UltiArjan is still asleep, i can help you out there ;)

    there are some small changes there, the Z stage has changed completely, but the temperature range and the glass plate have remained the same. I do believe it reaches the temperature a bit quicker as compared to the UM2 and UM2+ but that might just be my imagination.

    so i'll reply as well..

    the whole UM2 and dual extrusion discussion is pretty much dead. yes it was promised for the UM2, no it was never promised for the UM2+ and if you were expecting it for the UM2+ that is not something Ultimaker had anything to do with. sorry if that sounds harsh, but they have been very clear since the beginning of the UM2+ that that device would not do dual extrusion. if you were expecting it that;s not something you can blame on them..

    yes it was promised for the UM2 but they made a very good point about why it couldn't be done. and if you look critically at the UM3 (which i've been testing for the past few weeks) it is very obvious why it could not be done this way for the UM2.

    that being said, there's also the point of the UM2+ versus the UM3. the UM2+ is the improved version of the UM2. a lot of community feedback and testing went into that. the UM3 has, in my opinion, nothing to do with the UM2(+). it has a very different target audience, and a very different use case. the fact that some people are already saying they now need to replace all of their specialized nozzles with cores and how that is super expensive quite frankly just don't get it.

    this machine is not meant to be tinkered with all the time. this machine is a workhorse. you buy it because you need a lot of very reliable prints. done. if something's clogged or broken, you want to replace it on the spot with minimal downtime. if you put material in it, it needs to be back up and running ASAP.

    if you read the description of the UM3 carefully, you can see their target audience is universities, prosumers, prototyping environments. it's simply not the tinkerers.. if you want a lot of swappable nozzles, different feeders, and your own way of doing things, you need an UM2+.

    if you run them 24/7 and need a very reliable consistent printing experience, you need an UM3. they are simply very different machines.

    I run one of the, if not the largest 3d hubs of the benelux. i run 4 UM2+ printers 24/7 and I could not be more excited for the UM3. your comparison for 7 euros for a nozzle versus 100 euros is simply wrong. i've calculated maintenance cost for my UM2+ printers at around 125 euros per 500 hours, and I expect the print cores to last for about the same time. once the performance starts dropping, i'll throw out the core and get a new one. no more taking the head apart, risking damaging any of the axes, realigning the build plate etc. etc. you have to compare apples to apples.. if i run abbrasive filament through the head, i think i run a greater risk of damaging the feeder then the nozzle to be honest. but even if i damage the nozzle, I'll just charge more for abbrasive filament. it's just a business calculation. I can actually see my prices dropping with the UM3 instead of going up..

    that being said, if I'm focussed on building great models, like valcrow or any of the other great artists that we have on this forum, the UM3 would not interest me at all since it lacks the flexibility I would need. I would love the Um2+ in that case..

    anyway, that's my rant.. you gotta put things into perspective. the UM3 is not a successor to the Um2+. it's a new device for a new market. a market currently dominated by the 10K+ printers.. and I think the UM3 can easily hold it;'s own.

    Made by the new Ultimaker

    in Official news

    Posted

    Since we have tested the new machines for a few weeks I can say that I am pretty pleased that Ultimaker kept its open source mentality and build a machine that is user friendly *and* advanced user friendly at the same time. You are able to turn off every automatism the printer has and run it over spec.

    The print cores are awesome as they were able to take very different materials without a hitch. Printing ABS right after PLA and then Nylon and CPE is not something you'd have a nice memento of with other printers... Only PVA was problematic for me - even with the dedicated "BB" core.

     

    i can only second that.. been testing the Um3 for a while now and i run a 24/7 operation based on UM2s.. the Um3 is a different beast altogether, it's not better or worse then the Um2, it's different... and I love the new machine!

    ULTIMAKER 3 (DUAL EXTRUSION?)

    I thought the countdown was until 16:30. Or does another countdown start then :p

    Is there only a NY launch? Or also an EU/NL launch?

     

    There are launch parties in different countries, but I am not sure in which ones. At least I know there is one in Spain, The Netherlands, United States, Canada...

    I am sure @sanvervg know more about it. The only thing I am sure about is that tomorrow at 17:00 no matter where you live, you will know how the new Ultimaker looks like. :p

     

    poor people in the UK.. they'll have to wait till 18:00 ;)

    Anyone seen this approach to dual nozzles before

    ?

    Maybe this is the way the new Ultimaker is built? :D

     

    Could be that I'm just overlooking something, but isn't that just the default way of doing it? (eg the same way the UMO Dual extrusion kit does it?)

     

    in the video (after a while) there is a small mechanism that somehow lifts the head about 1 or 2 mm and lowers the other one.

    it's also the defacto standard way of doing this with 2 nozzles in a static head.. so not that surprising.

    I'm in no way unhappy with my UM2+, quite the opposite. It fits my needs well and I eventually decided against dual extrusion since I don't really need it in daily use.

    But it would have been  nice to have. People often dream about buying new cars even though they have one that perfectly fits their needs don't they? Dual extrusion opens up possibilities you can't do otherwise and it would have been nice to be able to do that on occasion. Of course we aren't sure what UM3 brings to the table yet so it's hard to compare the models fully.

    This was in no way meant as a serious complain or that I would like to return my still quite new printer. I just feel like my new dream printer was launched 3 months after I bought mine and now I have the need to find space in my house for a new one already :)If I had the money, or the need for dual printers hehe.

     

    i think that's a very healthy approach :)

    i always get very confused when people buy something, then a new version comes out, and now the thing they were so happy with is rubbish all of a sudden..

    I always think you bought something that fitted your needs, the fact there is a newer version doesn't make the old one bad..

    and yes, it will probably do more things :) but it might not fit your needs anymore..
