Abstract
A material delivery device includes: a plasticization unit having a screw and configured to plasticize a material by rotation of the screw to produce a plasticized material; a flow path through which the plasticized material flows; a nozzle having a nozzle opening that communicates with the flow path and delivers the plasticized material to an outside; a cylinder coupled to the flow path; a rod inserted into the cylinder; and a first pressure detection unit configured to detect a pressure of the plasticized material in the flow path via the rod. In a longitudinal direction of the rod, the rod has a rod end surface facing the flow path and a transmission unit at an opposite side of the rod end surface, and transmits a force due to the pressure received at the rod end surface to the first pressure detection unit via the transmission unit.
