The fuzzy skin function in 3D printing slicers opens up new possibilities for surface design. Originally introduced as an experimental feature, this technique has evolved into a powerful tool for texturing 3D printed objects.
Fuzzy Skin creates a rough surface on the outer walls of a 3D print. The function is available in popular slicers such as Cura, PrusaSlicer and Orca Slicer. Users can adjust parameters such as dot spacing and thickness to control the intensity and type of texture.
A particular advantage of this technique is the ability to apply it selectively to specific areas of a model. By using modifiers, users can precisely define where the texture should appear. This is particularly useful for functional surfaces such as grip surfaces.
An innovative application combines Fuzzy Skin with the spiral vase mode. Contrary to initial concerns about stability, such prints turn out to be surprisingly robust. This technique opens up interesting possibilities for the design of translucent objects.
One challenge so far has been the texturing of top surfaces. Michael from Teaching Tech presents a solution: a similar effect can be achieved on horizontal surfaces by over-extrusion and special infill patterns. The recommended settings include a flow rate of 170% for the top layer and a Hilbert curve fill pattern.
Despite its advantages, the fuzzy skin technique also has disadvantages. It significantly increases printing time and affects dimensional accuracy. These factors need to be taken into account for accurately fitting parts.
