Is there evidence that shows a trend in increased violent crime committed using 3D-printed weapons?

I’ve certainly seen projects and models demonstrating the ability to create firearms with the help of a 3D printer, but I’m not aware of anyone using one to commit a crime…

The Brian Thompson murder was with a 3D printed firearm.

A single crime isn't a trend.
