4. Behavior of zein under 3D printing conditions

4.1 Thermomechanical properties and melt flow

Zein plasticized by the addition of 20% by weight of glycerol has a glass transition temperature of approximately Tg≈42 °C  (determined by differential enthalpy analysis, DEA) – or DSC – ; figure  7 (a), with the primary mechanical relaxation of the extruded material, measured at
