has anybody experiences with selfmade wood filled filaments?

[janedoe92 0]

hello,

i'm new here and hope i'm posting my question in the right category.

has anybody made any experiences with extruding and / or printing selfmade wood filled filaments? i'd like to recycle wood-plastic composite materials, which contain about 75% wood and 25% PE, but the ratio might be alterable. (i think down to 50 / 50)

in general, for my experiments, i can use any kind of plastic and wood particles, but i need to know if i just can stuff these materials in an extruder and will get a printable filament.

can you recommend a plastic material which is suitable for that?

would it work with PE or with already mixed, recycled WPC materials? is it possible to print that with the ultimaker? what kind of extruder can you recommend?

the plan is to buy (or build) an extruder, i have access to severeal 3D printers, but first i need to know if my thoughts make sense, if this idea ist generally possible?

looking forward to your answers,

best regards,

elisa

Hi Elisa,

I believe Colorfabb uses PLA as a binding material for their woodfill and their ration is 70% plastic 30% wood. It can be a tricky material to use, let alone produce it.

What you should look out for is the wood fibers not being to big, so they won't fit through the nozzle. I don't know what kind of wood you are planning on using, but I can imagine if it has additives like glue that won't benefit the quality.
