There is nothing mysterious about dark matter. "Dark" means just that you can't see it, not that it's evil or something.
There is just lot's of stuff between galaxies, that is ... well... dark, as in "invisible to us". We know it's there, but we just can't see it.
It is the same kind of matter, that you can find in any other place. There is no need to try to "artifitially create" it. There is enough matter around us, without mor ebeing created artifitially.

There is increasing evidence that dark matter exists but no one is certain exactly what it is. This is one of the biggest current mysteries in physics, astronomy and cosmology. So far the evidence for the existence of dark matter is almost exclusively astronomical. Astronomers have been able determine by the way that light rays bend around large galactic clusters and the motion of stars and gas within galaxies that the amount of mass that they are able to observe from the emission of electromagnetic radiation (light, radio waves, etc.) is much less than the amount that must be there.
As far as what dark matter is there are lots of theories but no final conclusions. As far as creating it in the laboratory, they are going to try but so far they have not been successful. I believe that they think some of the next generation of powerful particle accelerators might have some possibility of success but at this point it's pretty much pure speculation. There are a number of theories (e.g. supersymmetry) that predict whole families of particles that have not yet been observed. There is the hope that dark matter may be some of these particles that have already been predicted but not observed.
