3D printers?

Just need a STL file to create items. Here is a vid of a piggy bank I created for the grand kids.

Yep. I've seen working ball bearings as well as working adjustable wrenches made that my daughter brought home from High School 8 years ago that they made on a 3D printer at school. I saw the machine work. It's incredible but yet so simple once you see it work.
 

So, to make a part or mechanism that HAS to be of metal (for strength, heat resistance, etc.) the 3D printer comes in for making a pattern for the metal casting? Just asking. :?
 
There are metal 3d printers. The metal printers are fairly high end units, like around $50,000. With them you can do all sorts of things like print precision miniature turbo pumps for rocket thruster engines. The aviation industry and those whom are making rocket engines have found that jet and rocket engines can be produced with a 25% operating boost to their efficiency.

It is a marvelous time we live in now. Even Airbus is starting to use 3D printers to create airplanes.

Holy Smokes! I had no idea ........ Thanks!
 
If you want to read about what is happening in the news with 3D printers I suggest you bookmark the website

3ders.org

They are showing off people whom are doing medical implants for both humans and animals. There are printers that are making specific human tissue like ears and noses from the hosts DNA. There are printers creating houses and buildings all over the world. You name it, people are working on creating it.

Some day they will be sending 3d printers to Mars to create habitation for colonists. The printer could be housed in a telephone type pole that parachutes to the surface. When it gets close to the surface it cuts away the parachute and self pile drives into the surface. From there it will deploy a solar array for power. A snake like auger will fold out and as it rotates will attempt to pull martian soil to it. Mixing compounds that was brought with it, this unit will create housing and other structures needed.
