Gaps between Infill and Outer Wall

This is by far the most common issue and is really easy to resolve. In your slicing software locate the ‘Infill Overlap’ option and increase the value

In Cura this is set to 15% by default. Raise it to 30%.

3D PRINTING TROUBLESHOOTING TIP: PRINT INFILL BEFORE THE PERIMETER SHELL

If you’re printing with a relatively thin outer wall the structure of the infill can show through. If this happens then you can switch the order by which the printer lays down the infill and perimeter layers. For example, in Cura check to see if you have ‘Infill prints after perimeters’ ticked.

3D PRINTING TROUBLESHOOTING TIP: LOWER PRINT SPEED

Okay, so you may be in a rush to get the printout, but printing at higher speeds can cause all sorts of issues if the printer isn’t perfectly calibrated. If you need to print quickly you can still avoid gaps by decreasing the speed of the top layer. […]
