The 3D printer rapidly sprayed carbon powder onto the already formed metal plate armor, then another robotic arm released an electric arc, causing carbon atoms to instantly oxidize and reduce, bonding and arranging in a set pattern to form complex fiber clumps.
This was the best buffer layer Xiang Shan could find under these conditions. It was capable of effectively absorbing mechanical waves, reducing the damage of mechanical waves to the metal and cellular parts. At the same time, the extraordinary conductivity of the carbon fibers could provide a certain level of electromagnetic resistance for parts inside the armor.
Once the lining was complete, the plate armor was cast aside by a magnetic field, falling onto a shelf of a drone. The drone quickly navigated within the base, transporting this alloy external armor to the Maintenance Instrument.
