I know its probably impossible, but I thought I'd ask

I’m making some storage boxes for resin domino sets that I’m making. I wanted it to look like older wood, so, to that end, I bought this filament from our hosts here.

After a little experimentation, I think I’ve succeeded in making something that looks like older wood (see the attached pictures). The lid in the pictures is the filament straight off the printer.

The problem is the top surface of the lid (and the top surface of the bottom of the box)

I’m using PrusaSlicer and Cura 5, and the problem is the same. The 45 degree angle that FDM printers lay down filament. The surface ends up with a crosshatch pattern (small, but noticeable) and, of course, the “stitched” border around the edge. The stain highlights these details. It kinda ruins the illusion that it’s finished wood.

I know about ironing, but, that requires VERY slow feed rates, and that is anathema to this wood filament. It needs a bigger nozzle (0.6mm), and fast rates (I use around 75mm/sec), to prevent heat creep and clogging. Ironing, I think, is out, but I stand to be corrected.

I can’t sand it, because it ends up looking too shiny, and strangely, more like plastic again.

What I’m wondering is, if it possible to change the orientation of the top skins so they print parallel to the sides? That way, they would look more like wood. I can’t find a setting that does this, and I think it’s not possible, but I thought I’d ask the experts here.

Thanks for any ideas

@Andy.wpg I feel like I saw somewhere that could be changed but for the life of me I cannot find it.

You might however try using Archimedean Chords it is a spiral that resembles growth rings.

Hilbert might also work maybe.

Good idea! I like both of those. Thanks!

I’d love to know if it does what you hope. I also wonder if you ironed the print got it as smooth as possible and then used a wire brush to create grain. Heated brush? or maybe just force.

I know it is totally different but I was looking at the modellers.

The monotonic feature can be made to go vertical/horizontal by using the directional notation circled.
This will show in the slicer and you may have to reverse the numbers to get the final x or y axis finish.

Yes that is where I saw it! OMG thank you. Making me crazy (crazier)

Wow - that’s cool!

90 oriented them them the right way.

I tried the first couple of layers in Hillman and the concentric one, but they aren’t the right look.

I couldn’t find an equivalent setting in PrusaSlicer, though. So, Cura it is.

I’ll give this a try, and keep the thread updated

I have tried using a wire brush, unfortunately, it tends to leave behind fine metal powder from the bristles. It appears that they are “sanded” off by the rough filament. Leaves grey streaks behind.

Good idea though, thanks.

Found it in PrusaSlicer!

Under Print Settings - Infill

I have the top and bottom set to monotonic, but you have to adjust the fill angle to get it oriented.

Sorry, I do not know the settings to get this right in PrusaSlicer.

I probably said it poorly. My post IS the settings for Prusa. I was just updating the thread
