If you needed to choose a polymer to do FFF/FDM, how would you rank the following properties in terms of how important they would be to the FFF/FDM process and the subsequent use of what you printed. Using bullets briefly explain what each property is and why the property it is where it is in your ranking. List the most important property first. a. Density
b. Elastic modulus
c. Coefficient of thermal expansion
d. Melting
e. Temperature and Glass
f. Transition Temperature
