I don't know if this helps but the PLA material specs this person uses and the URL he references to the source of the info is in the screen shot linked here. https://forums.autodesk.com/t5/fusion-360-ideastation-archived/add-pla-polylactic-acid-in-the-material-browser/idi-p/8627210?lightbox-message-images-9265801=719602i7815F1DF1C52EFC6

Thank you for linking this! I believe I did use the paper mentioned as a source, but I adjusted some of the values based on other work as well.

The paper mentioned in the screenshot is: "Mechanical Property Optimization of FDM PLA in Shear with Multiple Objectives" by Torres, Cotelo, Karl, and Gordon of Department of Mechanical and Aerospace Engineering, University of Central Florida

The parameters mentioned in this screenshot are as follows (in case the link ever breaks):

Basic Thermal:
  Thermal Conductivity: 1.300E-01 W/(m.K)
  Specific Heat: 1.280 J/(g.°C)
  Thermal Expansion Coefficient: 56.000 μm/(m.°C)

Mechanical:
  Young's Modulus: 3.500 GPa
  Poissson's Ratio: 0.36
  Shear Modulus: 1287.000 MPa
  Density: 1.250g/(cm^3)
  Damping Coefficient: 0.00

Strength:
  Yield Strength: 70.000 MPa
  Tensile Strength: 73.000 MPa
