Hey all!
I have been trying to find places that allow you to print your 3D models in unique materials. I think Shapeways is the best option so far, but I also found a company named i.materialise. They don´t print in as many materials as Shapeways, BUT they have a new trial project including printed wood. I thought it was super cool so I wanted to share. The prices are about the same as Shapeways. The wood appears to be more of a particleboard consistency, but still super cool in my opinion. Check out the link below:

Hey!! saw this one a few weeks back…In fact I was looking for places which printed wood! Unfortunately these guys are in Belgium!! unless you want international shipping :P!!
I just realized, thank you for pointing that out. It´s unfortunate because I think its one of the only places allowing for things to be printed in wood. All other wood 3D prints I could find are filaments for home based 3D printers.
