A different multi-extrusion approach - UM tool / printhead changer

[Dim3nsioneer 557]

Oh, how time flies. Have a save trip home.

 

Indeed.

@Labern: have two nice flights! Hope you had a good time across Europe last three weeks...

[Labern 774]

Thanks.

Yes time does fly by and I had an amazing time. The first week was the best though

Ok, here we go!

!!! Can you make me a knee? I would like it to take away

Great print !!

@foehnsturm: Great use case! Is it more or less as flexible as a real human spine?

Well I should test it with my knee first

Never had a real one in my hands 8)

But I assume, at little less flexible. I'll run another print with only 2 perimeter lines instead of 3, and even lower temp.

Hi foehnsturm

Where did you get the CAD template for the model come from?

Would like to try to print.

Thank you and greet

Marin

Geometry is not so much the challenge but using Filaflex which is one most difficult to print flexible filaments on bowden setups (and with a standard UM 2+ feeder).

Thanks, I try my luck

May I ask, what type of pancake NEMA17 that is? ebay/aliexpress etc didn't show results...

Have you tried a little light oil in the Bowden tube?

I modified Roberts guide for the feeder and I now have a small hole running through from the back, I then insert a small pipe cleaner in with a few drops of oil on it . I still get the odd bit of under extrusion from FilaFlex from Recrues but I like the filament.

[foehnsturm 969]

I used that trick already. But the current print was intended as challenge for the the Machtless block and Race nozzle. Just wanted to see if this one performs better with Filaflex. And so far it looks like that..

Recently, we discovered a small glitch in our firmware's e-axis calculation after a tool change. So, this is the result after bug fixing.

That looks sexy!

Any release info on a kit? Looks pretty good!

Still under discussion ...

Another test:

maybe you need help from lance to go even smaller

Knotted Orbit by emmet.

GreenTec PLA and PolySupport. With 230°C this was at the lower end of PolySupport's temperature range but it looks like still a little too hot.

Green? Looks like the black pla-tec that I use from extrudr. If it's that one, I had to change the filament size from 1.75 to 1.725 to keep a perfect top layer. Also imo it needs like 5-7C + of heat vs the same print done on faberdashery.

[foehnsturm 969]

It's the extrudr stuff andprinted quite well. But the support was more stringy than I expected.

Wow, 3d printing has come on a bit since I last logged in a few months ago! Still leading the field foehnstrum i see! Great work

[foehnsturm 969]

Thank you!
