Closer to natural
The key is that the wooden filament changes colour depending on what temperature it is extruded at. So if you print an object at 200° C, it will be lighter in colour than a print made at 230° C.
What Jeremie’s plugin does, is to programmatically vary the temperature of each layer, within a set range. The end result is an object that “looks more like wood and less like cardboard”:
Jeremie is not entirely satisfied with the result, since the texture is only horizontal, but he thinks that it’s an interesting change. He’s also had trouble with the experimental filament drying out and becoming brittle, so there’s still a ways to go before hobbyists everywhere are printing wooden objects.
This video captures one of the vase prints with temperature changes enabled:
