Dear fellow iMechanicians,
Here is our recent paper that studies and models the rheological behavior of PLA deposited by 3D printing and allows to highlight the important process parameters than enable a full healing of the interface between printed layers.
Abstract
The new group of Prof. J. Gaume at the Swiss Federal Institute of Technology of Lausanne (EPFL, Switzerland) invites applications by highly motivated, committed, and talented students/researchers for 2 PhD and 1 PostDoc positions in the field of Computational Mechanics for Snow and Avalanche Modeling.

Hi All,
I would like to know if anyone has had the opportunity to investigate cellular rubbers rheology. I am thinking of characterizing the viscoelastic properties of cellular rubber during cure and after cure in the rheometer, using ASTM D6601. What I am expecting is a distorted cellular structure due to very constrained foam expansion during the blowing agent's decomposition, so the results would obviously be different than the ones obtained from a DMTA machine.
Would like to hear from anyone with some rheology / viscoelastic characterization experience.
