As I’ve mentioned before, I’m new to 3D printing as of last week, and aside from my initial octopus test print, I haven’t had what I would consider a successful print since. Very frustrating. I’m hoping the community experts can help me trace down the issue(s) and help me resolve them.
Here’s what I would like to know for each Exhibit.
- What is common terminology for this particular phenomenon?
- What’s likely causing it?
- How do I resolve or mitigate the issue?
My specs for these prints:
ABS (IC3D High Quality Green 3mm ABS - http://www.amazon.com/gp/product/B00TVL4R2G)
Extruder temp: 240C
Bed temp: 110C
Settings: Usually the default “high quality” setting or a slight variation of that
The top 75% of the print looks amazing. If the entire print looked like this I would be ecstatic. What’s going on in the first layers!?!
Bridging looks terrible from the bottom up. The other side towards the top of the model the bridging looks better but still not great. How do I resolve this without bracing? This model was specifically designed not to need any bracing.
The bottom side looks uneven and rough compared with the top side. What’s going on here?
This is the only time I’ve seen this phenomenon happen that I can recall. The overall thickness to the model seems to have increased after the line. Also, the line is more predominant towards the front of the vehicle and then sort of “blends” in towards the back. What’s going on here?
This is obviously delamination of the layers. I think room temperature and possibly humidity levels maybe causing this. What is the recommended room temperature and humidity levels for printing ABS? Is there anything else that might be going on here that could be exasperating the problem?

After having all of these issues, I went back and closely looked at my first prints. The print that was printing by the factory looks really good. Initially I thought my first print was near perfect, but after looking at it more closely I can see there is some evidence of some overhang issues as pointed out in the above photo. What can I do to help mitigate this?
Any help you guys can provide would be greatly appreciated. I’m sure all of these issues are a result from my inexperience, so I’d like to learn what causes this issues and how to tweak my print process to neutralize them as much as possible.
I did a rough check of my e-Steps (don’t have an accurate way to measure mm) and it looks to be pretty spot on. I’m getting a set of digital calipers in the mail today, so I will go back and re-check it, along with measuring my filament width.
Thanks in advance for your help!
