PLA CTE (Coefficient of Thermal Expansion)

[sardar 0]

Hello.

 

Does anyone know the thermal expansion coefficient of the PLA that Ultimaker Extnded 3 comes with?

 

I have not been able to find solid information about the the thermal expansion coefficient of the PLA that comes with the printer. Moreover, I am finding contradictory information about the expansion coefficient online, for example 135 e-6 [C] in this paper  but 85 here , yet 41 in this  datasheet!! So, I would like to know if you have exact coefficient of thermal expansion for PLA's that come with Ultimaker 3 Extended, or any diagrams that show how this figure depends on temperature, or anything along the same lines please. 

 

Thanks
