TJ, there's one commercial multi-materials printer so far, and it prints both hard and soft polymers. It's the ObjetConnex, now owned by Stratasys. We've written about it a few times: http://www.designnews.com/author.asp?section_id=1386&doc_id=265793 http://www.designnews.com/author.asp?section_id=1392&doc_id=260118 http://www.designnews.com/author.asp?section_id=1392&doc_id=247146
I don't know if I'd call it a trend but the medical industry is moving forward quickly using 3D printing.
The printed jawbone Jennifer mentioned is cool. I just read on iht.com about living human tissue being printed too. If my ACL-less knees can be effectively re-printed and replaced, I'd take up fencing again.
3D printers are definitely fascinating everyone who just love the idea of being able the power to manufacture products on their own. I think that It might even lead to peope starting their own home business by manufacturing either engineering parts or decorative items. It would certainly bring a big change in the mind set of people.
One would guess a big goal of the printer manufacturers is to get into the home market. But to do that, I would expect people to desire a printer to be flexible with regard to matierals. I would not want a printer that could handle only one type of material. A printer that can fab both hard items and soft, or a mix of them both is the one that will take off.
Jenn, I don't know where I saw it (maybe here), but body parts have been printed for surgeons to use to practice for complex operations. These parts have the properties of the human organs from a surgeon's point of view, but are not "real".
On the other hand I have run into a small company that uses a CNC machine. They also us 3D printing for some specialized, one off, parts. They also just make stuff that is fun. I was over one day and they gave me a small Tardis made of a corn based plastic. How's that for new trends?
Jennifer, it seems that everything can be printed with 3D printers. Starting from space application tools to finally wearable clothes. If it's going like that there is no doubt it can print human parts also.
Applied Research Associates has delivered several of its Pointman Tactical Robots to the CBP in Tucson, which the agency is using to explore drainage tunnels that run between Nogales, Ariz., and Nogales, Mexico. These tunnels are out of sight from border surveillance and are increasingly being used for illegal activity.
