[ULTIMAKER 3 (DUAL EXTRUSION?)]

UM2 and 2+ owners, don't worry. I'm pretty sure Ultimaker's community will not leave you behind.

 

Fixed that for you.

[Made by the new Ultimaker]

I'm disappointed.

I mean, a reliable dual extrusion looks fine, but there is nothing really innovative for that price point.

People already developed equally interesting ways to do it, even as hacks on UM2/UM2+ models.

Those new "print cores" look like unnecessary complicated swappable hot-ends that are pretty far from the "keep-it-simple" approach and will probably be overpriced. Doesn't really fit in the open-source mindset.

But that's probably fine, as you are now only targeting professionals.

[Has anyone tried out ColorFabb nGen filament?]

Thanks a lot for your tips, gonna try that

[Has anyone tried out ColorFabb nGen filament?]

Hey guys, I'm also really disappointed with nGen.

It prints very well and the finish is good, but the layer bonding is terrible!

I tried different printing temperatures, even at 245 celcius, layers are not properly bound.

Am I the only one to experience that?

[Multicolor print]

This is probably a dumb question.

How do you guys ensure that the STL file you load into cura happens to be at the exact

coordinates, so there is no shift with the previous print ?

Thanks :>

[Did anyone try the new Advanced 3D Printing Kit?]

I don't see the logic behind selling the sheets as a kit only.

Once you used the 25 sheets, should you buy another complete kit?

What will you do with the ton of doors?

[Curling comparison - Colorfabb XT vs Esun PETG]

Hey,

I am quite disappointed with the Colorfabb XT filament, especially at this price point.

There is a lot of curling, especially on overhangs.

Strength-wise, I didn't feel any difference between XT and Esun PETG. It doesn't mean that there are not, simply that I didn't perform tests to actually measure it.

I should have tested the filament instead of relying on the spec sheet and marketing words on the official website before dropping 130 euros (4 rolls).

By the way, I contacted Colorfabb's support and they replied:

The results you have achieved with our _XT material are in line with what I would expect to see for such a model.

So yes, I would say this is an expected result.

It does seem indeed that eSun's PETG handles the dissipation of the heat better in this case.

Until somebody compare the properties of Esun PETG vs Colorfabb XT, I would advise you to stick with Esun PETG. You'll get a much better finish.

[[UM2] [UM2+] - Reduce plate vibration]

Don't forget to adjust for the reduced travel if you put something underneath the platform, it's pretty tight under there.

 

The steel plates I plan to use are of 6mm height.

I think it won't touch the chassis of the machine as there seems to be around 1cm of gap.

I really hope it works, it would be cool to finally have a stiff plate

[[UM2] [UM2+] - Reduce plate vibration]

Hmmm, in my original idea, I planned to put the bars ABOVE the plate.

But... actually is much easier (and quite obvious!) to simply put it underneath the plate, with longer screws

Good idea Meduza! Seems straightforward to do!

[[UM2] [UM2+] - Reduce plate vibration]

Hmm... But the rods are attached to a printed part screwed on the Acrylic panel where "Ultimaker 2" is written, no ?

That doesn't seem very rigid to me. Am I missing something ?

[[UM2] [UM2+] - Reduce plate vibration]

Here how the current plate looks like.

As you can see, there is a single hole that we could use.

Currently, there is nothing using that hole, at least on my model.

I'm not sure that this single hole would suffice to clamp the steel bar really tight, and I agree that it would ease a lot the overall project.

Plus, no original parts would need to be modified!

[[UM2] [UM2+] - Reduce plate vibration]

Hi,

Let me preface this by stating that I'm not an engineer, probably a dumb dude and very new to the 3D printing world.

I witnessed quite a lot of vibrations on the build plate of my Ultimaker 2+ and I think that it has a detrimental effect on the quality output.

I was wondering if we could put two small steel bars as an attempt to rigidify the whole plate and limit those vibrations.

I checked with my local hardware store and they supply flat bars of 35mm wide and 6mm thickness.

Here is a quick model I did, based on the source files of the plate shared on Github (thanks btw :->.

I calculated that each of those bars weight ~500g, so I would be adding more or less 1kg to the current plate.

A quick check with a 1kg spool filament showed me that the motor seems to lift the plate pretty well, not sure if the Z-accuracy is conserved though.

Do you think that adding those bars would help with the vibrations ?

Thanks for your help !

[Stains on alluminium bed]

Hi!

I have my Ultimaker 2+ for 3 weeks and enjoy it very much so far.

I recently identified some stains on the aluminium bed, just below the glass.

I tried to wash both the glass and the aluminium bed but it didn't do much.

It seems that the glass facing the aluminium got a little bit deteriorated at this specific spot (rough to the touch).

Should I be concerned ?

Thanks!
