All it takes is a 405-nm laser, a 3D-printer or CNC router, and a roll of Kapton tape. As [Zach] ... This foam doesn’t have all the usual properties of monolayer graphene, ...

Kapton is an aromatic polyimide with outstanding thermal and dielectric properties. It can do things few other plastics can do, like withstand temperatures from nearly absolute zero to 400 °C.

Brief History of Kapton Wires Material scientists and structural engineers are consistently tasked with balancing essential thermomechanical properties that may appear mutually exclusive.
