Morphology

extruder = extrude (transparent) = extrude + er

The agentive/nominal -er is added to the verb 'extrude' to denote a machine or device that performs extruding, a directly compositional relation.

Etymology

Extruder comes from the Latin extrudere, made of ex- 'out' and trudere 'to push'. So an extruder literally 'pushes out' material, which is why it is a machine that forces material through a mold or die to shape it.
