RISExtrusion Process Modeling for Aqueous Based Ceramic Pastes—Part 1: Constitutive Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The extrusion process for aqueousbased ceramic pastes is complex due to the nonNewtonian behavior of these pastes. In this study, the extrusion process is modeled by characterizing the ceramic paste viscosity using a ...
Extrusion Process Modeling for Aqueous Based Ceramic Pastes—Part 2: Experimental Verification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the Part 1 paper, a constitutive law for the extrusion process of aqueousbased ceramic pastes was created. In the study described herein, a capillary rheometer was used to calibrate the viscosity of an alumina paste, ...
Hybrid Extrusion Force Velocity Control Using Freeze Form Extrusion Fabrication for Functionally Graded Material Parts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Freezeform extrusion fabrication (FEF) is an additive manufacturing (AM) process that uses an aqueousbased paste loaded with ceramic or metal powder to build complex, threedimensional parts by extruding the material from ...
