Cura's Fuzzy Skin Feature - Add Texture to Your 3D Prints

The Cura Fuzzy Skin setting is a feature that adds a unique textured surface to 3D printed objects. This setting can be a great way to add a creative and artistic touch to your 3D prints. In this article, we'll explore what the Cura Fuzzy Skin setting is, how to use it, and its advantages and limitations.


What is Cura Fuzzy Skin?


Cura Fuzzy Skin is a feature in the Cura slicing software that allows 3D printing enthusiasts to create a unique, textured surface on their prints. Fuzzy Skin works by randomly varying the extrusion rate of the printer nozzle, which creates a textured surface on the printed object.


The Fuzzy Skin setting can be a great tool for creating decorative or artistic objects, or for hiding imperfections in the 3D printing process. It can also be used to simulate natural materials like wood or stone, giving 3D printed objects a more organic feel. However, it's worth noting that Fuzzy Skin may not be suitable for all 3D printing applications, as it can result in reduced dimensional accuracy and structural strength. It's important to test the setting on a small scale before using it on larger, more complex prints.


Enable Fuzzy Skin

Before we get started, make sure that you've installed Cura, preferably the latest version, but any version after V2.1 should work. Also, ensure that you've set your visible Cura settings to "All". 

To enable the Fuzzy Skin setting in Cura, follow these steps:

  1. Open Cura and import your 3D model.
  2. Click on the search bar and type "fuzzy skin".
  3. Enable the "Fuzzy Skin" setting by clicking on the toggle switch.


Adjust Fuzzy Skin Settings

After enabling the Fuzzy Skin setting, you can adjust the following settings to customize the texture of your 3D print:

  • Fuzzy Skin Outside Only: This setting tells Cura to only generate the fuzzy skin texture on the outermost walls of a model. If you check this feature box, internal features like screw holes won't have fuzzy skin.
  • Fuzzy Skin Thickness: This setting controls the magnitude and depth of each nozzle wobble used to yield the fuzzy skin. Increasing this value will make the surface more uneven and the fuzzy skin more noticeable.
  • Fuzzy Skin Density: This setting controls the density of nozzle wobbles used to make the fuzzy skin. The higher this value (measured in 1/mm), the more jitters the nozzle will make in a given area, causing the surface to be rougher and more detailed.
  • Fuzzy Skin Point Distance: This setting is inversely affected by the "Fuzzy Skin Density" and is the distance value (in mm) for the wobble density. This setting determines the average distance between the points where the nozzle wobbles in each line segment.


Generate G-code and Start Printing


Once you've adjusted the Fuzzy Skin settings to your liking, you can generate the G-code and save it to your computer. Then, send the G-code to your 3D printer and start the printing process.


Advantages and Limitations of Cura Fuzzy Skin


  • Provides a unique, textured finish to 3D prints, which can be desirable for certain projects or applications.
  • Can create a more natural or organic look, which can be useful for printing models of organic shapes or surfaces.



  • Fuzzy skin can increase print time, as the printer has to create more movements and wobbles to achieve the desired effect.
  • The fuzzy skin effect may not be desirable for all prints or projects, as it can obscure details and make the print less precise.



By using Cura's Fuzzy Skin setting, you can add a unique textured surface to your 3D prints. Experiment with different settings to achieve the desired texture and effect. Keep in mind that using the Fuzzy Skin setting may increase the print time and use more material than a standard print, and may not be suitable for all 3D printing applications due to reduced dimensional accuracy and structural strength.
