Yes, we have Hyrel users who print with Hot Melt Adhesive 3796 from 3M (essentially a high performance hot glue) with our Krakatoa series print heads.
These heads don't print with filament; the user fills a metal reservoir with paste, gel, or even powder or granules, loads the reservoir onto the head, loads the head onto the printer, applies heat if necessary (some models up to 250C), and then prints the gcode with positive displacement. The KR2 is like the KRA above, but it is made specifically for higher temperature, higher viscosity materials, with tighter tolerances and multiple gaskets.
I have used this model head to print materials including hot glue, polycaprolactone, porcelain, vasoline, toothpaste, plasticine, and metal clays.
See https://www.youtube.com/watch?v=QD2FrZ4kg1g for an overview of this head.
Note: I sell this equipment, and have used it since 2012.
