In my previous blog I asked for any of the readers and Ultimaker users to share some of the experience you were having with Dual Extrusion. I am glad to say I have got some feedback and I would like to share this with you.
We have received quite a few pre-orders and I am happy to say no serious leadtime was formed. Everyone received their Dual Extrusion within a couple of days.
The word on the street is that the wiki-instructions on how to disassemble, assemble and calibrate the Dual Extrusion have reached an all time high and are considered to be rather detailed.
Even though the Dual Extrusion upgrade is considered to be experimental I virtually only hear positive experiences. The most criticism is, as expected, about oozing. In the second slideshow in this blog I added a picture which illustrates this, but also what kind of beauty lies beneath. The oozing could and should be reduced to a minimum/zero but that is something I believe we can all work on.
A few tips on how to bring the oozing back to a minimum:
- Print at the lowest temperature possible. 190Â°C seems to be a good temperature for a normal speed (50mm/s) but if you are suffering from oozing it may be worth experimenting with a lower temperature.
- Put your fanduct at the appropriate angle so you get maximum cooling.
- Make sure your Dual Extrusion offset is calibrated. X, Y and Z.
- Set retraction speed to 40/50mm/s at 4,5mm
If anybody has any additional tips, please share your knowledge.
Here in the head quarters we have doing some testing and making some more Dual Extrusion prints:
Some more info:
Layer height: 0.12mm
Print time: 45hours
I also received some pictures from the community, which I want to share. Thank you Nelson!Â I did not take the liberty of downloading images from the forums without permission.Â What I consider good about these pictures is that you can see the oozing, but also how good it looks after a clean up.
