Hi, I got just back from my trip last night and I decided to print a simple double color test overnight, the results were very good. Printed in ABS in fine settings, it took about 4 hrs. Sorry for the crappy pics, not enough time to take them properly.
I’ll try to post more pics and experiments with dual printing soon. Sadly I haven’t been able to get ahold of some PVA or HIPS filament to test dissolvable support, but hopefully soon!
Cheers
Looks pretty descent. It looks like there is a small indent where the top orange meets the white.
@luis-bustamante is that something you modelled or downloaded?
also did you import STLs or OBJ files as i have had a few problems with import and needing to ungroup and then parts moving on the layout area that i have reported to support
@microcan I believe the indentation you mention is caused by a slight missalingment of the nozzles. The calibration process is a bit coarse so that’s as close as I was able to get it with that process. I haven’t had the opportunity to fine tune it directly in the numeric head parameters.
@streatsi This was downloaded from Thingiverse here. To load the separate stl files correctly you have to load them together (select both files in the dialog box that comes up when you press the “add model” button in Automaker). I have been able to load stl files created in Fusion360 in the same way, creating a separate STL file for each part and then loading them together in Automaker. When importing files this way they are loaded as a group and you can double click to select the different shells and change the material per part. This system works but is a bit difficult when loading designs with several parts, as the selection can be very difficult if one part is occluded by another. That’s why I mentioned before that it would be good to have a list to select the different parts even if they are not visible, similar to the list we had in prior versions of Automaker.
So, continuing with my testing, yesterday I tried to print the famous dual color frog found here but the postprocessing failed and aborted the print without providing any feedback, I tried several times with no luck. I’ve had problems loading very complex models in the past so I’m thinking Automaker has some limitations when loading files too big, I did tried to fix the model in Netfabb but I haven’t tried to simplify it through 3D Builder so that might help. If the problem persists I’ll post a ticket later, but it would be great if some of you with the DM head could confirm if this is a bug in Automaker or something wrong with my setup.
I’ll let you know how it goes. Good day to all!
@microcan I forgot to add that I think the calibration of the nozzle separation parameter is crucial to have proper overhangs where the 2 materials interact with each other and I think that might have the reason the 3dbenchy boat test posted before didn’t come out as well as it could. I just wish I had more time to play with the printer!
In any case, I’ll keep you posted on my progress.
Talking about the 3dbenchy in the article below there is some interesting info about bridging, for the roof part of the boat. If you have exactly the right speed, temperature and cooling you a reasonable job.
Thanks for the link @microcan, I’ll check it out.
