Anyone want to talk about wood(fill)?

I know that there's been a little bit of discussion about it previously, but I figured it would use it's own thread. I did a test figure to see how easily things would stain and what it would all look like when done.

It's not super obvious on a camera, but srwas that didn't get sanded have a sheen to them (that looks decidedly not wood). However, the ability to rub some of the stain off (after giving it time to absorb) did give some parts that lighter hue, which is nice.

However, getting a woodgrain effect seems like it'll take work. Either through velocity painting (waaaay more work than I really want to get into) or other means. After some drinking thinking, it occurred to me that I could purposefully use an incorrect layer height (like .21mm) that will result in an occasional 'off' layer due to stepping limits. That forced high then low layer should sand and stain differently than the rest, and give a grain effect, right?

I'm pretending to be a single parent the week (wife is out of town) so I don't have time to test this, but figured we could at least talk it through. What are your thoughts?

I've also heard that setting your slicer to print at different temperatures at varying heights has an effect on how wood PLA looks when stained.

In my limited testing that did not hold true. I tried two different brands and they looked the same.

That's unfortunate. I wonder if the people who reported these results used a specific brand with a different kind of wood fill.

I don't know. I was excited by that report too, but never actually saw any prints. It's a Bigfoot style Urban legend as far as I can tell.

I've got a spool that I will test next time I get around, but I'll bump it on the list.

I have some Miniwax gunstock stain lying around as well. Will report back with results.

I'm mostly curious about how weak it'll be... we'll see tho.

I'm also planning to do a 'wood' stock for my marker project, so I'll add to that data point collection soon too.

What two brands have you tried so far? I had heard that the Hatchbox stuff was the best, but admittedly i have not tried any wood-fill PLA yet myself

3d Hero and Geeetech. Both are inexpensive on Amazon.

I hate wood filament > keeps breaking at the spool, weak brittle filament. My spool must need drying but we'll see if that helps.

On a positive note, it prints nicely, "seems" strong after printing but my sample is quite small to test loads.
