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)

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
