How 3D printing fills the gap between the outline

By  Steve Lowry 2018-10-02 10293 1

How to solve the gap between the outline in 3D printing? There are two settings here that you need to check, is easy but helpful.

gap between the outline

Overlapped contours

There is a setting in CURA that allows you to adjust the bond strength between the outline and the fill. Click "Tools - Open Expert Settings – Infill overlap  (%)". This value is based on the percentage of your extruded wire width, so it is easy to expand and adjust for different nozzle sizes.

infill overlap

For example, if you set a 20% overlap, this means that the software will command the printer. The fill will overlap 15% with the outermost edge. This overlap helps to ensure that the two parts are strongly bonded. For example, you used 15% overlap before, try increasing to 20% to see if the gap between edge and fill disappears.

Filling prints too fast

Your print fills parts too much faster than the outline. If the fill is printed too fast, it will not have enough time to adhere to the outer contour. If you try to increase the overlap of the outline but still see the gap between the outline and the fill, then you need to reduce the print speed.

infill speed

You can modify the infill-print speed in Advanced. For example, 30mm/s to see if there is any improvement. Try twice or more times to find the best result.
