Hello Everyone!

Printer: Flashforge Creator Pro
Filament: ColorFabb PLA (1.75mm)

Was printing the 3DBenchy Boat (https://www.thingiverse.com/thing:763622) and was getting some filament drooping/sagging on the overhang. The overhang angle looks like it's around 30 degrees, so I figured I could handle that (I have yet to benchmark the overhangs, however ). Here are some pics:





Here's my factory file:

The photos above depict the model printed with the "Fast" quality configuration.

What I've tried so far:
Print speed: From 60mm/s to 55mm/s. Didn't see any improvement.
Upped to "Medium" print quality: Reduced layers that sagged, but issue was still prevalent.

My nozzle temp of 200c is fine - I've done some testing to remove 'zits/blobs' and I've found that printing at 200c works for me for this particular filament.

What I am thinking:

• I really think this should print without supports better than what I am seeing here.

• Do you think printing slower would help, or does this not apply?

• Could the bed (50c) be causing that overhang to droop? The overhang starts to droop at approximately 3mm from print bed.

Thank you!

Lower the outline underspeed and decrease the layer height. Those will both help with overhangs.

Yes, print slower and give thing time to cool.

Thank you for the replies everyone. I printed off a new fan duct (https://www.thingiverse.com/thing:1675208) to help distribute air flow towards the nozzles, and that did it!


- Medium settings

Overhang came out great. Are the zits/blobs shown in the image something that I can fix, or is this something I'll just have to live with?

Can changing my retraction settings really help?

Thank you again!

For me, enabling coasting fixed most of the blobs. I would suggest enabling that first at 0.2 mm and seeing if it helps/fixes the issue.
