Electronic Sensors and High-Tenacity Fibers are both 3D printer ingredients in Call of Duty: Modern Warfare 4’s DMZ, and you loot both of them in Hajin. Each one comes from a specific container type. Container loot can change between deployments, so treat the spots below as places to check rather than guaranteed drops.
Quick answer: For Electronic Sensors, check the IT Bag on a desk inside the holding-cell building in Cheongun Village, west of the D50 Radar. For High-Tenacity Fibers, search the Duffel in the Hajin City barber shop at grid F8.
