I'm curious what other things you might build with a 3/d printer?
You don't need to! There are several libraries filled with tens to hundreds of thousands of designs, ranging from marble tracks to spare parts of old appliances. Even something as a custom gear can be generated quite easily, fill in the diameter, amount of teeth, pitch and this site will generate a design for you.

The only reason I haven't got into 3D printing is that I haven't wanted to put in all the time to learn 3D modeling software. I figure if I ever NEED a 3D print I'll just have to pay someone to make it for me. If you are going to go for it Tom, then the turbine blade math and fluid dynamics probably aren't any harder than the rest of the modeling process.
John Weiland wrote:Not so much a windmill idea, but if 3D printers become efficient with the production of hardened materials, I can see all kinds of older farm equipment that could be repaired through 3D printer parts manufactured based on a 3D template. Even for newer equipment that may have been imported and for which parts are hard to find domestically. Right now, I have a Yanmar F15D with a broken front grille. It's made of molded plastic, but it's one of the parts that I would probably have to special order from Japan. Don't know how far off is the ability to print parts with the integrity of hardened steel. ?....

In order to decide if it was worth while to buy one, I made a list of things that I could build/repair/maintain with one - also to see how large a printer I would need. The largest thing I think I would want to make with a 3d printer is the blades for a vertical axis windmill. I have seen some models that use blades that are 24" long. Has anyone seen designs for wind turbines that can be built with 3D printers?
