16:Holes and Gaps in Floor Corners
When building a 3D printed part, each layer relies on the
foundation from the layer below. However, the amount of plastic
that is used for the print is also a concern, so a balance must be
achieved between the strength of the foundation and the amount of
plastic that is used. If the foundation is not strong enough, you will
start to see holes and gaps between the layers. This is typically
most obvious in the corners, where the size of the part is changing
(for example, if you were printing a 20mm cube on top of a 40mm
cube). When you transition to the smaller size, you need to make
sure that you have a sufficient foundation to support the sidewalls
of the 20mm cube. There are several typical causes for these weak
foundations. We will discuss each one below and present the
settings that can be used in Simplify3D to improve the print.
(1) Not enough perimeters
Adding more outline perimeters to your part will greatly
improve the strength of the foundation. Because the interior of
your part is typically partially hollow, the thickness of the
perimeter walls has a significant effect. To adjust this setting, click
