3D Printed smokeless powder

[Cris T]

I am too old and no longer can take on projects. But If I could. I would develop 3D printed smokeless powder. There are so many possible applications. This is just an idea for you folks that have the means and education to work on this project.
This video shows just one of the possible applications:

I don't understand how this would work. You can't 3D print gunpowder...

Until someone does.

It is an interesting concept; perhaps someone will achieve it some day. It seems that doing so will be far more costly in both time and materials should it be achieved.

If powder can be extruded, adding a chemical binder or light reactive binder should be doable. Powder has been extruded and cut for over a century. We just need to solidify it quickly in the printer.

3d Printing, with the exclusion of SLS, is just extruding. Nothing to really "3d Print". You just need to extrude it and cut it at the same length, then dry it. Formulating it is a bigger hurdle, given a lot of the ingredients are somewhat restricted. If you want different size kernels, you just adjust the diameter of the die, or the length of cut. There is nothing to 3d Print in my opinion.
