Tips to close open gaps at the top of a figurine.

[burleysavage 0]

Hi, 

 

First timer. I am printing smaller figures on a .4mm nozzle using a .16 layer height. The issues I am having are how can I avoid gaps in the very end or top portions of the prints. As you can see the infill because the gaps were not closed. Normal temps for me have been 220 degrees and 65 plate temps. Speed is normally 75. Wall line count is 2. I already know I should try to print slower but I am trying to figure out if a setting is the issue. I am planning to print the German Shepard and I noticed I might have the same issue on the forehead and snout. The bear figure is about 30 mm tall.

 

Any help I will appreciate!

Hey burleysavage, 

It's a bit hard for me to judge what is going on just from the pictures.

 

I ususally try to avoid changes in speed and temperature, they have a lot of impact on your quality so I try to stick as close as possible to the default settings. 

 

But there are several settings that improve top faces:
- Increase Top Layers - This will add more material at the top layers
- Increase Skin Edge Support Layers - This will build up a structure to support the top in the infill

- Enable gradual infill or select the Lightning Infill Pattern - This will also build up a structure to support the top in the infill

- Lift Head - This will give the layers time to cool off before starting a new one

 

Good luck!
