FDM prints can be significantly enhanced visually with suitable texture techniques. One example shows how wood grain can be simulated through the targeted use of modifiers in the slicer – without having to make any changes to the model itself. Maker and YouTuber PandaN demonstrates this by using an STL model of a tree stump with concentric growth rings and applying it as a modifier to other objects.
In this specific case, the stump model serves as a so-called modifier in the slicer. This function allows certain print parameters to be changed only at those points where the object to be printed overlaps with the modifier. In this project, the fill angle is changed specifically in the affected areas. In addition, a “fuzzy skin” surface option is used to give the object a textured surface.
Combined with a wood filament – a PLA material with wood particles – a visually convincing effect is created. The structure created is reminiscent of a natural wood grain, especially if the layer heights and printing temperatures are correctly adjusted. As the filament also has the olfactory properties of wood, the print gains additional authenticity.
PandaN not only provides the STL files of the tree stump modifier, but also a prepared project file for the Bambu Studio Slicer. This makes it easy to replace new models without having to manually reconfigure the parameters. This enables quick tests with different geometries.
