The application of a permanent marker, glue or tape makes gummy metals such as aluminum, stainless steels, copper and tantalum much easier to cut for industrial applications. (Image courtesy of Purdue University/Erin Easterling.)
Permanent markers, glue sticks and packing tape may offer a surprisingly low-tech solution to a long-standing nuisance in manufacturing: Making soft and ductile, i.e., “gummy” metals easier to cut.
What makes inks and adhesives effective isn’t their chemical content…
