October 2014 - Designing a prototype source pt. 2

A project log for Low Cost X-Ray Systems for Developing Nations

This is the result of 3,500 man-hours of labor and love, but we need your help to push it forward, HAD community

To house all the electronics, I needed a plastic shell. Actually, several plastic shells; one for the high voltage oil tank, one to hold an x-ray tube, one to hold aluminum filters, one to hold the high voltage oil tank, a handle to hold everything... it goes on!

To design these, I broke out my favorite CAD suite: Autodesk Inventor. I also broke out the caffeine, and spent some 14 days staring into inventor, to design the following *injection moldable :D* parts

-

A model of my chosen x-ray tube:

-

A shell to hold the tube, and a lead jacket around it:

-

An oil tank, to hold the tube, the shell, and its wrapping:

-

A lid for the oil tank, and a rubber chamber to allow for thermal expansion:

-

Aluminum filters of different thicknesses, and a disk to hold them in place:

-

A shell to hold the oil tank, and other parts:

-

Sides, and a handle to allow for easy carrying.

-

An LCD, and PCBs to hold components, buttons, and the voltage multiplier:

-

And finally, a top shell and a rubber flippity-flap to cover the power receptacle:

                                         |___/ 



Then came the 3D printing, the long, torturous 3D printing.

Some people have trouble with parts peeling off, but often, I have the exact opposite problem. x_x
