An industrial replicator was a large-scale replicator, typically used for construction purposes.
Deep Space 9 housed an industrial replicator on Level 17. In 2373 a Changeling posing as Julian Bashir overrode the security blocks on the industrial replicator and used it to produce a bomb consisting of trilithium, tekasite, and protomatter. Odo discovered the override by the saboteur but was unable to determine what was replicated because the memory core had been wiped. With that explosive device the changeling aimed to destroy the Bajoran sun along with the combined Federation, Klingon, and Romulan fleets in the system. (DS9: "By Inferno's Light")
