Challenge - chap 3D printer

tada9

Hi Ben,

I have a chalange for you.

Try to build the cheapest possible 3D printer by hand with no use of CNC or 3D printer.

It should be based on Raspberry PI(another chalange?) becouse it is cheaper than Arduino.

    There are hundreds of people building 3D printers everyday continuously looking for ways to build them cheaper, myself included.  I think that at this point in time if you want a usable printer, it's not going to be possible to do it for much under $400-$500, and even that is pushing it.

     

    As for the stepper motors from old printers, most of those stepper motors are strong enough to move in 3 dimensions.  As for the ballscrew, you need something to move the print head around - and using a ballscrew is fairly accurate.  You could use a trapezoidal screw, or belts but then you have other things you need to consider.

     

    That being said, I'd love to hear or see about cheaper alternatives, but I've been thru it so many times I can't imagine building an entire printer from scratch for any less.  Between the stepper motors, electronics, linear bearings, etc.

    If ti would be easy, it won't be chalange.
