The present invention is a method for obtaining a ceramic slurry for the production of filaments for 3D FDM printing, comprising adding a polysaccharide, a glycol or an ethanolamine as a gelling agent to a suspension of ceramic material in order to produce said ceramic slurry. The invention also comprises the green body obtained from said slurry and the ceramic filament extruded from the green body.

Provided is an intermediate base material (incised prepreg) which has exceptional surface quality and mechanical properties when solidified and with which it is possible to obtain a fiber-reinforced plastic having excellent three-dimensional shape conformance properties. This incised prepreg has, in a prepreg that includes a resin and reinforcing fibers oriented in one direction, incisions substantially parallel to the orientation direction of the reinforcing fibers (the incisions substantially parallel to the orientation direction of the reinforcing fibers are referred to as parallel incisions) and incisions that cut across the reinforcing fibers (the incisions that cut across the reinforcing fibers are referred to as intersecting incisions).

A resin molded article contains a thermoplastic resin, a filler dispersed in the thermoplastic resin, and protein short fibers each having a fiber length of 24 mm or less and dispersed in the thermoplastic resin.

A small piece supplying apparatus includes: a raw material supplying section that supplies a raw material sheet; a coarse crushing section that coarsely crushes the raw material sheet supplied from the raw material supplying section to produce small pieces; and a reservoir section in which the small pieces produced by the coarse crushing section are accumulated. The raw material supplying section includes a feeder roller that feeds out the raw material sheet, and a contact section that changes a course of the raw material sheet by contact with an edge of the raw material sheet fed out by the feeder roller.
