Some test blocks to show how to use “fuzzy skin” settings to add texture to a part.
Previously I created a small set of test blocks intend to to show a significant amount of “fuzzy skin” on the surface of a 3D print. As I noted then, the meaning of the fuzzy skin settings is pretty straightforward, but the actual results obtained are hard to visualize. So I created a set of test blocks to provide actual physical examples of various fuzzy skin settings combinations.
This new set of test blocks uses more modest fuzzy skin settings in order to provide a small amount of surface texture to a print. This can be useful in several ways :
- to give a print a more pleasant “feel”
- to add a matte finish to a surface
- to hide minor imperfections in a print
- to disguise the “layer line” appearance of a print
Each block includes two combinations of settings, and the settings are printed on the top of the block. This enables the blocks to be kept as a visual reference for future use. For this remix, I added a column to the table below for print time - note that some settings add a significant additional time to the total print time.
| Block Number | Point dist. #1 | Thick. #1 | Point Dist. #2 | Thick. #2 | Print Time (min) |
| 2F | 0.3 | 0.3 | 0.5 | 0.3 | 19 |
| 2F | 0.3 | 0.2 | 0.5 | 0.2 | 19 |
| 2H | 0.2 | 0.1 | 0.4 | 0.1 | 20 |
| 2I | 0.1 | 0.1 | 0.3 | 0.1 | 21 |
| 2J | 0.4 | 0.4 | 0.6 | 0.2 | 19 |
In addition to the above, a “blank” block is provided (with the two sides labeled A and B). This block can be used to test additional settings combinations.
Additional observations :
For this set of prints, my primary interest was the “feel” of various fuzzy skin settings, as opposed to the look. However, I think it is accurate to say that for the settings used in this experiment, the visual effect was a add a finely pebbled appearance to the surface. As for changing the surface feel, in all cases the fuzzy skin settings created a textured surface which was perceptible to the touch, but at the same time does not feel “rough.” For objects like handles which need a non-slip gripping surface, these would be a useful addition.
Print Instructions :
Print the blocks in PLA using the 3mf provided. Files are provided to print each block individually, as well as a 3mf file to print all of the blocks at the same time. After printing, I used a felt tip pen to highlight the settings printed on the top of each block.
Note that the fuzzy skin does not “exist” in the STL files - it is an effect created in the slicer. If you simply load and print the STL files all you will get is a smooth block. This is also why you do not see the effect in CAD.
The fuzzy skins are added to each block by creating two modifier blocks (one for each side), and adding a fuzzy skin setting to each modifier block.
If you want to try additional settings combinations, load this file into PrusaSlicer :
- TestBlock2 - Box.3mf
The above file is already set up with the necessary modifier blocks; simply change the fuzzy skin settings as desired.
In general, the following settings should work :
- 0.2mm layer height
- 2 perimeters
- no infill
