Difference UMO+ vs UM2

Recommended Posts

Functionally quite similar. The UMO+ comes in a kit so you have to build it yourself, and the UM2 is pre-assembled.

In terms of operation, the UM2 is more automatic. More settings are stored on the machine itself like filament diameter, retraction settings etc. Whereas the UMO+ you configure that in cura.

The UMO+ is more mechanical in nature, so you can turn the extruder wheel by hand, disconnect the extruder and manually move the filament. UM2 is more automated, and those things are controlled through the menu. There's a wizard for changing filaments, leveling bed etc. UMO+ assumes you know how to do those things.

Hardware wise, UM2 has 3 fans on the head, one on each side and one to prevent the heat bleeding upwards into the filament. UMO+ has one big fan on the left. Generally the UMO+ is easier to self service. nozzle is easy to unscrew etc.

In terms of print quality, they can get quite similar. My UM2 prints better than the UMO+. There seems to be less stringing and blobbies and it seems overall more consistent. The UM2 prints wonderfully smooth surfaces. But this is a very small margin of difference. LIke you would need to compare the objects side by side to really see the difference in quality.

The biggest difference between the two is the ease of use. The UM2 is just plug in your file and hit print and leave. the UMO+ requires a little bit more attention. You need to pre-heat, then manually prime the nozzle a little bit to make sure it goes down smooth.

Thank you for that reply. it helps

I would love to get the UM2 as its the latest and greatest available. but it would cost be $2700 (CDN). I have never used a 3d printer and whatever i get will be my first machine.. in a way I want to get the Original+ as I want the experience of assembling the unit myself (remind me of the great time i had a a kid assembling my first RC car) I learned alot. the Original+ would cost me $1700 (CDN) still alot..

maybe I should start off with something low end.. in the $500 range to get my feet wet any recommendations for low end machines?

if i printed the same file on both would i see a difference?

 

Probably not. The biggest difference tends to be that the UMO belts are a bit loose which is easily fixed. The quality of my 2 machines right now is pretty damn close.

The "Printrbot simple makers kit" might also be something then. It's in that price range, a kit, so all the fun of assembly. Perfect to get your feet wet without spending a lot of money.

It does not achieve the same quality as Ultimakers. But you get what you pay for I guess. There is however, an quite active printrbot community, and the machine has been around for a while. And I've heard little complains about the latest offerings of Printrbots.

Different in print quality between the UM2 and UMO is mostly between find adjustments (which have been done in production for the UM2, and thus less to worry about there). And the dual-fans of the UM2 give better cooling for small prints. However, installing dual fans on the UMO is possible.

And the UM2 oozes a bit less, meaning certain prints with lots of retraction come out better for the UM2.

And the length of the heated area in the nozzle is shorter, which should help with printing of very fine detail (or so i've been told). I haven't printed up to a resolution where I was able to notice a difference.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
