This is touted as a major discovery.
In fact people have been exploring and building and trying to sell a variety of 3-d printers.
Form fill filament is just one technology.
another technology is using an injet printer to print a binder on plaster powder one layer at a time then dipping the part in Ca or epoxy to finish it.
SLS selective laser sintering uses powdered metal as a base and a high power laser melts the selected are together.
STL stereo lithography uses a laser to selectively cure a liquid polymer. Or turn the monomer into a polymer. though selective heating.
the paste extrusion method above is another viable option.
there is company in England selling a 3D printer for decorating cakes and other food.
I see a future with refrigerated 3d printers and chilled bed plates for printing chocolate and Ice cream.
I see numerous articles of 3-d printed organs and body parts still experimental but there could be a future of 3d printed organs for transplant.
NASA and GE are using the technologies to make metal parts for the aerospace industry.
The one caravat is sometimes it is hard to separate the true breakthroughs from the dreams the hype and the gadgets.
So more than one technology competing and complementing,like I said earlier in the toddler stage. What will it look like when it grows up. will it thrive or fail.
IMHO a lot of R & D is going into this. So an ever changing landscape I think 3-d pringing will be a big part of manufacturing in the future. And like computers the applications are near endless.
