Getting Woodfill to print on a UM2

Filemon · 2015-02-21T11:42:12.000Z

Wow, really sweet man!

Filemon · 2015-02-21T11:48:15.000Z

Ps. what kind of print bed do you have? Looks amazing

avanhanegem · 2015-02-21T13:05:19.000Z

That looks really nice indeed!

“I am grut”

That’s buildtak. Works great. I have never used anything else, so I have never experienced the inconvenience with glue and tape etc.

It works in 90% of all cases, but I will get a second build plate without buildtak.

BjornTM · 2015-02-21T13:42:06.000Z

The second attempt did fail again… Damn. It was over 2 hours in, and then suddenly the extrusion stopped again. It’s still way better than before since it stopped within 30 minutes before, but still no 100% success rate yet.

BjornTM · 2015-02-24T18:40:36.000Z

This is still my ONLY successful print with woodfill. I tried several other prints and all failed. My nozzle blocks every single time…

I have the same problem Bjorn, and I’m still searching for the most optimal setup. Any luck since the last post here…?

P.S. since i have lots of people asking me about woodfill and other special filament so I ordered 3dsolex “Olsson Block”, new modification for UM2 (link to the UM forum: http://umforum.ultimaker.com/index.php?/topic/7689-custom-heater-block-to-fit-e3d-nozzle-on-ultimaker-2/) and since it will allow me to change nozzle easier and to even be able to print with bigger nozzle I hope it will make all the difference when printing woodfill. But untill then still frustrated with failed prints.

I actually have an update: I printed 3 (Three) wooden objects without any problems now.

The trick in the end was to set the speed even higher.

I now have:

First layer: 20mm/sec (I think you might need to raise this for larger objects when the first layer takes very long)

Layer 0.2mm

Outer shell layer: 50mm/sec

Rest: 80mm/sec

Retraction: 5.5mm @ 40mm/sec

Layer 0.15mm

Outer shell layer: 50mm/sec

Rest: 100mm/sec

Retraction: 5.5mm @ 40mm/sec

For the rest of the settings I used the standard Cura Normal Print settings.

I noticed that even though I set 80 as overall printing speed and set the others to 0, that top and bottom still had variable speed. When I set the speed on 80 manually (so not on 0) it seems better and less risk of getting stuck at the final layers.

I tried the outer shell @ 80mm/sec but that gave a very ugly result.

Another trick I learned: In cura, you can add a second Ultimaker to your machines, but in stead of ultigcode you choose the Reprap / m… something. This gives you more options in the gcode, like printing temperatures, retract settings etc., so you don’t have to set them manually on the printer. I added a line to the starting gcode to make sure 30mm of material is extruded though, since in the default settings there is NO extrusion at the beginning. I’ll upload my profile later, so you can simply open it in Cura after adding and selecting the UM2 with different gcode setting.

Whoops I pressed submit before I was ready.

The Marvin above is scaled 200% and printed @ 0.15mm layers. The others (attached in this post) are print at 0.2mm.

WOW! This is sweet man

Mikrotvornica · 2015-02-27T16:02:42.000Z

Wow, Bjorn…this is awesome. Thank you so much for the information. I will try it out today.
Just one more question, at what temperature did you print these…?
And once again, great job.

BjornTM · 2015-02-27T16:15:47.000Z

210C nozzle, 50C bed

I’ll post all relevant settings tonight when I’m at home.

Mikrotvornica · 2015-02-27T16:25:57.000Z

Thank you so much. I so wish that it works, I’m setting up my UM2 as we speak.

BjornTM · 2015-02-27T16:34:20.000Z

lol yeah it’s exciting when it finally works

I’ll post a small howto tonight including how to setup a second printer profile etc… Hope that it helps for a lot of people since this stuff seems almost impossible to print

BjornTM · 2015-02-27T16:34:56.000Z

Didn’t you ask before? It’s buildtak (buildtak.eu) bought it from Makerpoint.nl

I am now successfully printing with Colorfabb Woodfill

Check my blog post here. Printing profiles provided.

BjornTM · 2015-08-26T13:45:06.000Z

I’ve been tweaking a bit after the post above I think. Did you try the profiles from bjornsblog.nl?

I do have those resin drops though. Usually after the first few layers. When I see it I pause the printer and whipe the nozzle clean. I do this very fast since this is obviously a risky operation with Woodfill.

My WoodFill prints are successful in many occasions, but still not always. It’s a beautiful material but it’s almost impossible to print 100% successful with it.

Alexander_K_hn · 2015-08-26T13:57:06.000Z

Great, thanks for sharing your experience, Bjorn! I am trying to print with ColorFabb Woodfill for a while now and can’t get it to work flawlessly. Your settings helped a bit, but still, I get these resin drops before the nozzle becomes clogged (See attached image, which shows just the support structure with one drop). Sometimes after a few millimeters of print height, sometimes significantly later (few centimeters). I tried the settings from your blogpost, from ColorFabbs blogpost and played with temperatures between 195 - 210. No success… Has anybody else experienced these resin drops?

Thanks everybody,

Alex
