Fat first layer makes screw holes too tight

Recommended Posts

(Ultimaker S5)


Hi all,


My problem is that a fat first layer (perhaps even couple of layers?) makes features like screw holes too tight. The fit is fine the rest of the way through the hole providing I allow for shrinkage.


My first layer looks really good, generally. What should I be doing differently?


Thanks :)

There is a setting that can help with this, it is known as elephant foot.


The setting is called horizontal expansion for the first layer, if you set it to a negative value like -0.2 it will reduce the effect you see.


(I'm not 100% sure of the setting name i'm not in front of cura)

      The goal of this contest is to design a set of people figurines that could be used in such a project to make an area, office or mall seem populated. 
      Think of different types of people in different environments, like walking people, people standing still, working people, and both men and women.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
