I just tried a new filament from Prusa, Woodfill Linden Light. After printing it looks, smells, feels and has the weight of light wood. Stains like wood. One of the best parts, you don't have to dry it! Works with a 0.4 nozzle and prints well.
I printed a cabin and my eyes cannot see layer lines, the texture of the printed filament hides it. This is a picture of the cabin, 2 roof pieces and chimney assembled, but not glued yet.
I think this will do well making many "Wood" landscape projects.
