PRINT WOOD
May 22, 2015 09:57AM
So I am looking into venturing into wood with pla filament on my prusa i3. I saw this neat article on how to create wood band looking effect by varying temps while printing, does anyone know how this actually works from a software point of view.

So far I only know the slicer software in repetier. I believe this requires a code and python software? I would appreciate some insight on how to integrate them together.

I'd also like to see any prints of those of you who have used this to generate a actual print.

Thanks

Well I don't use Repetier but Simplify3d and with it you just set multiple processes with different temperatures at different layer heights. But if your printer have a display, you can manually change the temperature as the part is printed.

I have printed with wood, but have not changed the temperature instead I use a little butane torch to create effects in the outer layer.

In Cura this function is called " tweak @ z"
But the butane idea I like better grinning smiley

I use Gizmo dorks for most of my filaments and the wood one they carry haven't give me any problems.

Regarding pictures, sorry I don't have any because are customers parts, but if I have some time this weekend I'll print a little piece (expensive filament) and take some pictures.

With the butane torch you need to be gentle and fast, you don't focused too long on a spot you do several fast passes with plenty of cooling time between them.

One key point is to make sure you're using a large-enough nozzle. I tried printing Laywoo with a 0.4mm nozzle and it jammed.

At least 0.5mm is required, probably larger than that to be safe.

I print with 0.5 without issues, but print slow for better results, and let the part cool for a while before you attempt to pull it out of the built plate.

Some wood filaments (laywoo and colorfabb woodfill for example) degrade quickly in the hotend so maybe better not "too slow".

What hotend do you have? Can you get different nozzle sizes for it?

I just saw that ColorFabb has a 30% wood filament with finer particles. While their own site says very little about it, other places claim it'll work with a 0.4mm nozzle.

However, they also say that it doesn't change color with temperature, so banding effects aren't achievable.

ColorFabb Woodfill Fine

You might try to create banding effects post printing.

If you use DMSO with abs wood filament, it can leach color, and some polystyrene. The rate of change would depend on the surface area exposed to the DMSO.
I haven't seen PLA wood filament, but you could use ammonia on that one. It can darken wood pulp, and get some alterations in the polymer.

I like this wood ...i'm not a big fan of ABS, had a bad first time experience with the beds acrylic support warping with the heat.

If I change out my nozzle to .5mm what is the potential negatives when printing my regular white PLA? Bad quality?

I could just drill out my .4mm to .5mm

A larger nozzle means less detail in the print, and less sharp corners.

I'm can't comment about drilling out nozzles. I've never tried that.

What hotend do you have? For some (e.g. E3D) swapping nozzles is easy enough that you could have one wide-ish one, like 0.6mm, for wood, and a 0.4mm for everything else.

I tried that once. It didn't work with newer versions of Cura.
