John Hart, who had done much for raytracing quaternions and 3D IFS fractals, has some IFS code in his thesis. I took his Elm Tree and Grass setting and put them into my UltraFractal 3D IFS program. Here is what I got:


It look like prehistoric tree. Probably  most often IFS looks like prehistoric plants cause they are more basic.

Of course a triangular mesh of a fractal dust would be huge at any useful resolution. In practice meshes are always a compromise, especially for fractals with uniformly rough surfaces because there's not much scope for mesh simplification. Point cloud export would be more efficient for the 3D Cantor set, and the size is not constrained by memory. However, 100 million points (the current limit in XD point cloud export) is still only 464^3. You can do really cool animations with such point clouds in 3DS Max with Krakatoa or Realflow. However, for high resolution, export is a long way from competing with direct rendering (except for 3D printing, where it's currently ahead.)
