Hi,
I’m a newbie here in the HUBS, and I’m printing the famous marvin keychain, I have tried many times, but never with successful results…Here are my photos
At the very beigining, I tried with no support, but it never happened to me, all failed
My printer is a Deltabot Dforce, with extruder of 0.3mm, slice software is CURA
PLA: 0.05mm, temp. 200C, walls 0.9~1.5mm, print speed 20~45mm/s, travel speed 180~210 mm/s, fill 15~20%, fan ON, no support, etc…
The results were too bad…
Then I thought without the support I could never finish it, so I added the support and changed the layer to 0.1mm, print speed 25mm/s
This is what I got at the end, I’m still not satisfied with the detail, but I think layer 0.1mm seems OK, and I wonder how you guys finish this test printing? For me it is really strange, I have spent two much time to print such a tiny thing!
Do you think this will pass the test??
Thanks for a feedback

I have wrote “extruder 0.3mm” but what I intend to say is “nozzle 0.3mm”, sorry for the word…;-p
Did you try printing multiple Marvins separated by some traveling distance?
No, I didn’t try that…The slicing results for 1 single Marvin were from 1 hour 40 minutes to 3 hours 20 minutes, so I didn’t think about it in that way, but I should try tomorrow, the models will have more time to be cooled, this may help, thanks for your idea 
The print does really seem to take unnecessarily too long. Try increasing the printing speed to at least 90 as well. And you could want to try printing a good one in 0.2 resolution first and then starting to reduce the resolution to figure out the machine!
Let me know how it all works out
Hi Arnoldas,
Yes, you are right, this morning I found out that 0.2mm is really better. I printed a single one using a speed of 20mm/s and the results are much better, you can check it in the photos below.
Thanks for your support

Glad to see it worked out! Make sure to share more prints, once you get a hang of your printer. Cheers
Hi Gabriela,
I already uploaded some photos of my prints, welcome to check
