Humans exploring Mars will probably get around in a Humvee-sized rover with a pressurized cabin like this one NASA is testing in the Arizona desert. It contains about 70 parts made with a Stratasys production-grade Fortus printer, including pod doors, camera mounts, vents, and housings.
Ann, I just wanted to say. I know I go on and on about this 3D printing, but it just fascinates me to no end. We talked just a few months ago about materials and they are already here. Like you said, it's progressing very fast. I'm just really interested in this.
That person would still need machining knowledge. At least knowledge of the measuring tools. I can see it as a trade school thing. Now instead of going for machining you go for 3D printing. I might be wrong, but it seems possible.
I agree about tight tolerances. The fact that this technology is being used in commercial aircraft and medical applications speaks volumes about its success in achieving consistent, repeatable, very tight tolerances.
One more thought. One thing that comes to mind to me, being an ex-machinist is the precision i.e. tolerances they can hold. I am betting they get better at that. You can print something all day long with whatever material, but if you can't hold certain tolerances then it isn't good for precision work.
A lightweight electric urban concept car designed by several European companies weighs only 992 lb without its battery. It would have weighed 26.7 lb more if its windows were made of glass instead of the specially coated LEXAN polycarbonate resin from SABIC Innovative Plastics.
Skylar Tibbits' team in MIT's Self-Assembly Lab is now 4D printing self-assembling shapes made of programmable carbon composites and custom wood grain. The composites are being used in a sport car airfoil, and the wood grain is beautiful.
The NanoSteel Company has produced high-hardness ferrous metal matrix composite (MMC) parts using a new nanosteel powder in a one-step 3D-printing process. Parts are 99.9% dense, crack-free, and with wear resistance comparable to M2 tool steels.
The company that brought you 3D-printed eyeglasses has launched both an improved clear polymer material for 3D printing optical components and a high-speed, precision, 3D-printing process for making small- and medium-sized batches in a few days.
