3D printers, anybody ever build one?

A CNC laser/plasma/water table would be 10000x more useful than a 3D printer.

Pat-you know there is a machine shop in the basement of physics department...Bob who runs it allows staff to use the shop with waiver and a little proof you know what you are doing...along with normal stuff mills and lathes there is a 3 or 5 axis CNC that is not even being used b/c they dont really know how run it/maintain it??

So yah thanks Zarken. Looked at youtube for homemade waterjets. Found laminar flow fountain sat for 45 min watching that thinking water a neat fountain for the pool. So much work to do. Dammit!!

lol, Yeah I have seen those. Things are awesome. And you're welcome.
 
I will agree that I mostly print useless shit with my printer also. Depends what you're trying to do really. You will probably notice 75 percent of the things you can download to print are more parts for your 3d printer lol. It is cool to draw some small part in CAD and then have it in your hand a couple hours later though.
 
Yup, I know Bob well. I've played with both of those CNC machines, and I was hoping that I could eventually buy that little 10krpm one from the university.

Where I have seen 3d printing excel at lately has been two areas.
1. Casting Models. You create a 3d part. Make a 2 piece mold using the 3d printed part. Then create a poured casting of the item.
2. Thermo Form molds. Create the basic mold you need. And have your vacuum table setup and form away.
