I share with you some photos showing P-51 Mustangs on aircraft carriers. There was a naval version of this plane? To see the photos, visit the link below:

A quick search (or even just a visit to wikipedia) will reveal that while there were tests of a version modified for carrier landings, carriers were used to transport large numbers of the aircraft to the Korean war theater. (This posting is wildly off topic here and will probably be removed by moderators.).

Umm, exact same text posted to the "Off topic" foum of some south african internet provider, same "I share with you some photos" intro used for various aviation-related topics posted on (mainly) aviation-related message boards. Somebody desperately trying to drive up site views or ad revenue, flagging
as spam.

Seems to be a new pilot material there, and from the few pictures I found it seems to be similar to shapeways' Metallic Plastic with a sawdust filler instead of aluminum. (Does not look that appealing to me from their pictures - like a cross of miscolored FCS and tea-stained strong&flexible. Or salt dough gone wrong :-) )

Actually it is more than a surface treatment; it is comprised of fine wood particle powder laid down and laser sintered to the previous layer.

Which is why I likened it to "metallic plastic" - surely this is not pure powdered wood but some cellulose-filled thermoplastic polymer if they are laser-sintering it.

This is their official description of the material:

"Models printed in our wood material are constructed from a brown, very fine powder made from wood chips."

After some more reading, I think cellulose acetate (cigarette filters, artificial silk) would appear to fit the bill, and there has been some research into using selective laser sintering of this material to generate biodegradable tissue scaffolding for biomedical applications. So I stand corrected (but still do not like the visual appearance of that material - but if it is cellulose acetate it is probably easier to dye than shapeways' nylon). I am curious what would be the advantages of having this material ?

I think the better question is, will shapeways get a CDC machine... Its not 3d printing but it fits their business model. I imagine the files and workflow would be similar. Id love to do some work on blocks of aluminum... Guess I can go else where for this work but it would be nice to mesh this work into my store.

Also did anyone hear about the nano CDC machine on kickstarter? Called like PocketCDC or something like that. Really expensive but very cool looking. That may be something more financially feasible for shapeways to implement.

Just my two cents, enjoy.

There was some talk about wood laced filament for home printers. Not sure how popular that ever became.

http://www.3dprinter.net/wp-content/uploads/2012/10/wood-filament.jpg

I could see a woodish powder print having some advantages for sound related projects since it might dampen audio resonances better than plastic. Or it might take paints/varnishes better. It's probably weaker than WSF or aluminum plastic and more prone to breakage and handling damage. It has appeal for woodworker-like projects but it does look a bit egg cartonish. If it were 1/4 the cost of WSF with reasonable strength I could think of some practical applications like bird houses. Quite frankly if there were a low resolution much cheaper 3D printing process I wouldn't care much what the material was even if it was paper pulp made from ground up newspapers.
