| Abstract Scope |
Non-beam additive manufacturing methods (AM) like binder jetting and fused deposition modeling commonly require an additional post-processing sintering step to densify porous parts to a desired level, in order to achieve a certain mechanical strength threshold. Due to the viscous creep of the porous material as it undergoes densification, such AM-built parts commonly experience undesired deformation in the form of warping, shrinkage, frictional drag etc., which are further exaggerated depending on the geometry of the part. This ultimately introduces dimensional variability and uncertainties in the final part. Continuum modeling approaches in sintering may be able to aid in this area via the prediction of final displacements and eventual geometric compensation of the parts. This talk will cover continuum modeling approaches and framework for modeling sintering process and the challenges associated with said approaches. |
