Fundamental field replicator
A fundamental field replicator was a handheld synth tool used to replicate material through a neurocotamic interface. 

In 2399, the synths of Coppelius Station provided Cristóbal Rios a field replicator as a means of repairing his vessel, La Sirena. () Doctor Agnes Jurati later also used it in a duplication-ruse while fighting a Romulan fleet. ()
